System Analysis and Design Waiters on wheels
They were two students Sue & Tom Bickford studying in college who also worked as part time
job in a restaurant and always dreamt to open their own restaurant. Their initial investment was
always out of reach so they noticed many restaurants that offer home delivery service .They got
an idea of opening their own restaurant without high investment .This idea came to their mind
after meeting many people who wanted home delivery service with their complete food
selection. By this, they opened a restaurant “Waiter on Wheels” in 1997.This restaurant provides
food delivery to the customers by gathering the meals form different restaurants and providing
under one roof. Customers liked this service very much and their business waiter on wheels was
increasing day by day. As there was increase in the number of customers and their orders they
started facing some problems to run their business effectively.
Analysis of current system
Now we are going to analyze the current system of waiter on wheels. Customer calls waiter on
wheels to place the order, waiter on wheels will then inform to related restaurants and to driver to
take the delivery form the restaurant and place it to the desired customer address. The driver
picks the order form restaurants and delivers to the customer and comes back to waiter on
wheels.
Problems faced in existing system
Limited user involvement
Inadequate resources & requirement
Business requirement have changed between commencement and deliverance
Absence of CASE support for analysis and design
Low level of involvement of users was due to lack on ownership and assurance of the
system
Inadequate techniques
Inadequate designing and tools
No updating of database management system
Solutions for the existing problems:
4 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
The only solution for the problem is to adapt the computerized customer support system to
support their business operations which will help them with the accurate and faster calculations
to produce
End of day deposit slip
Weekly report of restaurants
Sales report as per their desire i.e. weekly or monthly
Able to record orders effectively and informing end user efficiently
Inform drivers and restaurants at a click of button.
Increase delivery performance by flow of data in an efficient way
Feasibility study
Feasibility is defined as the viability of project feasibility does not solve any problem but it gives
a scope of solving a problem. The aim of our feasibility report is to find out the problem of the
current system in waiters on wheels and meet the end users requirements.
Realism of project
To decide whether the aims stated in the project are realistic within the given constraints.
Scope of improvements
In current system there are lots of problem with recording order, producing day and weekly sales
report which leads to inconsistency in delivering the meals ordered on time and running the
restaurant. We are developing a system which will help sorting out such problems effectively
and efficiently.
Specialist assistance
We are developing a user friendly system so that no specialization is required to operate the
system, even a person with little bit knowledge in computers will be able to operate it.
Principle work area
5 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
To determine whether the principle work areas relating to the aims stated in the project permit
planning of full investigation including the project teams departments and application involved.
Feasibility report
Our feasibility report consists of:
Technical feasibility
Operational feasibility
Schedule feasibility
Economic feasibility
Technical Feasibility: Technical feasibility address three major issues
Is the proposed system technology is practical
Does the organization currently possess the necessary technology
Does the organization possess the necessary technical expertise
And if the technology is not present then is it affordable by the organization
Generally, the technology for the any defined solution is available. The question which should be
considered is whether that technology is mature enough to be easily applied to the problem.
Some firms like to use latest technology, but most of the firms prefer a mature and proven
technology .A mature technology has a larger customer base for obtaining advice concerning
problems and improvements.
Assuming that the solution’s technology is practical, the next step is to determine whether it is
available in the organization has the capacity to use it?
If the answer to nay of the above questions is no, then the possibility of getting it from outside
should be considered. If it is available outside, but is too costly for the organization to purchase
it, then the alternative that requires the technology is not practical and is technically infeasible.
6 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
Operational feasibility: In operational feasibility study measures the urgency of the problem or
the acceptability of a solution .There are two aspects of operational feasibility which should be
considered.
Is the problem worth solving, or will the solution to the problem work?
What do the end users, and the management feels about the problem?
This feasibility was carried to get the answer to the question whether the system will be used and
implemented if developed. Would there be any resistance from its users.
PIECES FRAMEWORK
Performance: Receiving customer order till delivering Order.
Information: How the information is passed from WOW – Driver - Restaurants
Economy: It is cost beneficial
Control: Installing password, firewall and antivirus , so that there is no unauthorized
access
Efficiency: System is time efficient and effective, providing the information on single
click
Services: System will provide desirable and reliable service to customer and end users

Economic feasibility
The economic feasibility underlies the whole system development effort. We assume the
Economic feasibility to analyze the cost of the project in order to know whether it is worth
spending to develop the system. The system that we are going to design is flexible and less
expensive which will provide immediate access to records that are only periodically updated.
Cost – benefit analysis
This to analyze,
The cost to develop the system
Which includes man power costs, and the technology used to build the system etc.
The business cost
If the system is developed then what will be its maintenance costs?
Selecting the methodology
In this we have to select the methodology for our project i.e. Waiter on Wheels customer support
system. Basically there are two types of methodology used for the projects Structured System
Analysis and Design Methodology and Object Oriented Methodology.
We have chosen Structured System Analysis and Design Methodology (SSADM)
Reasons for selecting this methodology
It provides measurable, reviewable and definable product specification.
At the end, the process draws on more system personnel resources as well as user involvement.
It increases involvement and communication between system and users.
9 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
It also allows allocation of simpler tasks to junior personnel which mean each and
every .member is equally distributed among tasks.
A great impact of this methodology is that the total time and cost are greatly reduced, if system
developed by this methodology is implemented in the organization.
Stages that should be followed SSADM

Detailed business specification
Customer calls waiter on wheels to place the order, Waiter on wheels then informs to the related
restaurants for the order. Waiter on wheels then checks the availability of the driver and informs
driver to pick the order from the restaurants then restaurants will give the order to the driver
The driver will take the order and deliver it to customer, after delivering the order driver will
come back and give the bill to waiter on wheels. Now waiter on wheels keeps the record of each
and every restaurant, what are the orders taken from them and on which date and time. Weekly
or monthly waiter on wheels will pay the bill payment as per the wholesale price or the deal what
they have done.
Flowchart
A flowchart is a formal graphic demonstration of a logic sequence, work or built-up process,
organization chart, or similar formalized structure. Flowcharts are used for designing and
managing a program. It is represented by various symbols to show the flow of data in a logical
manner, each and every symbol has different meaning.

Physical design takes this logical design blueprint and produces the program specifications,
physical file or database definition and user interface for a selected target hardware and software.
These programs and files will fulfill the logical design requirements but may be subject to some
constraints and compromises.
Design objectives
The system is designed based on the objectives set for the new information system in the
strategic plan. Organizational objectives such as:
Increasing the business profit
Securing a larger market share
Improving customer service
There are three main objectives which the designer has to bear in mind while evolving and
evaluating design
Performance, how fast the design is secure against human error, machine hardware
resources
Control, the extent to which the design is secure against human errors, machine
malfunction, or deliberate mischief.
Changeability, the ease with which the design allows the system to be changes to, for
example meeting the user’s needs to have different transactions types processed.

started facing some problems to run their business effectively. So they decided to have a
computerized system to manage all the difficulties in their business. For the same they hired a
consultancy. We are working on the same and have clearly documented in the project. How to
overcome the existing problem? By making use of System Development Life Cycle (SDLC).
System Development Life Cycle (SDLC)
26 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
Systems Development Life Cycle (SDLC) is any logical process used by a systems analyst to
develop an information system, including requirements, validation, training, and user ownership.
Any SDLC should result in a high quality system that meets or exceeds customer expectations,
reaches completion within time and cost estimates, works effectively and efficiently in the
current and planned Information Technology infrastructure, and is inexpensive to maintain and
cost-effective to enhance

Design Implementation
System Analysis and Design Waiters on wheels
In an organization or for a project system analyst is required to carry the project effectively in a
well planned manner. System analyst must possess some necessary skills as
System thinking: Must be aware of inter-related object or elements of the system. Once we have
identified system, must be able to understand the principles and concepts about system to guide
the design of information system and can easily co-relate with the environment.
Organizational knowledge: Must understand working procedures and function of the
organization.
Problem identification: Must be able to understand the current situation of the organization or
project concerned.
Problem analyzing and solving: Once the problem has been identified, then analyze the
problem how to solve it with the proven methods and documents. For analyzing and solving
problems some approaches need to be followed as: intelligence, design, choice and
implementation.
Technical skills: Must know to develop computer-based information system, further be practical
to adept with different notations for representing or modeling the various aspects of information
systems.
Management skills: As a system analyst must be able to manage work and use the resources of
organization in efficient and effective way.
System analyst is almost the member of project team and is frequently asked to lead the team. In
spite of working in a technical field system analyst must possess interpersonal skills such as
communicational skills (interviewing, listening and questionnaires).
Analysis of current system
28 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
For this project Waiter on Wheels current existing system has been analyzed in an effective way
as:
Customer calls waiter on wheels to place the order, then waiter on wheels informs to
related restaurants they have contract with
Then send the driver to take the delivery form the restaurant and place it to the customer
address
The driver picks the order form restaurants and delivers to the customer and comes back
to waiter on wheels
Driver took the payment including retail price and service charge from the customer and
reports to waiter on wheels office.
Problem identification
The major problem with waiter on wheel was they were not able to manage the extending
business as they keeps record manually.
Not able to manage database of customers
Not able to get the delivery on time specified by the customer as they were having only
one delivery driver
Solution for the problem
To have a computerized system so that it can keep the records and saves time and human energy
as well. This will also help to get the customer details such as address, contact number, etc…; if
the customer calls next time to place an order.
Selecting the methodology
29 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
In this we have selected the methodology for our project i.e. Waiter on Wheels customer support
system. Basically there are two types of methodology used for the projects Structured System
Analysis and Design Methodology and Object Oriented Methodology.
We have chosen Structured System Analysis and Design Methodology (SSADM)
After having meetings with the team the methodology was selected with the clear justification to
other related methodologies.
Reasons for selecting this methodology
It includes portioning a large system into a manageable smaller ones and organizing the
details into an understandable by utilizing a top-down approach.
It provides measurable, reviewable and definable product specification.
At the end, the process draws on more system personnel resources as well as user
involvement.
It increases involvement and communication between system and users.
It also allows allocation of simpler tasks to junior personnel which mean each and
every .member is equally distributed among tasks.
A great impact of this methodology is that the total time and cost are greatly reduced, if
system developed by this methodology is implemented in the organization.
It also includes developing and maintaining the system specification, especially for the
outputs
Example of structured methodology
An integral part of this methodology is the modular concept. Under which frame work can be
separated in a detailed management information system. For example the finance system of an
organization can be divided into minor and basic modules.

A logical design is conceptual and abstract. The process of logical design involves arranging data
into a series of logical relationships called entities and attributes
An entity represents a chunk of information. In relational databases, an entity often maps
to a table.
An attribute is a component of an entity that helps define the uniqueness of the entity. In
relational databases, an attribute maps to a column.

Conclusion
While doing this project I have reached to conclusion that SDLC is one of the best methods to
carry a project in order to save time and to learn the project management. Among this one of the
most important phase feasibility study taught us to do researches on various Technical and
operational issues that are required for almost all project. The methodology that we have choose
for developing the system required by waiter on wheel is also an one of best among other related
methodologies. Which teaches different techniques for developing an information system?

Abstract
I have played the role of logical designer, and had contributed mainly in logical designing and
operational feasibility as well. The main objective of the project is to identify the different
framework of activities associated with methodologies and describe how the techniques are
used together to develop a system. The selected methodology SSADM has been clearly
justified and compared to other related methodology. Logical designs are mapped accurately
with physical design by the physical designer of the group.

Operational feasibility: Operational feasibility is dependent on human resources available for
the project and involves projecting whether the system will operate and be used once it is
installed. In our project we have analyzed that the contents of operational feasibility in this
project are:-
Implementation
Processing
People oriented
Government agencies
Implementation: Implementation consists of three parts:
Taking order- in this process we are designing our system that will be able to receive orders from
customers it is going to work like this when a customer calls on phone or orders online the
system is going to record the call by the name and address and the order specified, when the
order is recorded by name and address the system is going to make beep sound which will alert
the operator and he will be able to hear the voice call directly on the desktop.
Order delivery: in this process the system is concerned about how the order is going to be
delivered this comes under processing which I will explain further.
Reporting back to office: in this process the system will keep a record of the drivers who are
reporting back in office after delivery.
The next step of operational feasibility is processing:-
processing contains following contents:-
1. Receiving the call from customer: which I have already explained that the system will
be able to record the call from customer according to their name, address and specifically
the order.
39 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
2. Informing the driver: In this process we have given the facility that system will be able
to inform driver according to the given database , we will store the names of driver in
accordance with their areas our system will be able to check the availability of driver by
following methods when a driver calls to the office and says that he is available the
system will immediately record his message and the time of call so it will be easy or the
operator to check the availability of driver and when he clicks the option call in front of
the names of driver then the system will immediately call the driver and the operator will
be able to inform him or leave him a message. And as the driver conforms that he is
ready to pick the order the system will be able to store his out time on the request of
operator clicking on the button out time.
3. Informing the restaurant: The next main step after informing the driver is to inform the
restaurant so we have done the following we will give the data base of all the contacted
restaurants in the system so the operator will be able to inform the restaurants according
to the requirements and the order specified just on a click.
4. Picking the order: Next is all manual process in case the customer wants to change his
order then we have decided a time limit for changing the order it is 15 minutes after the
original order if the customer calls in between fifteen minutes of his first order then our
system will be able to recognize the customers voice and in case voice does recognition
does not work system will recognize according to name and address of the customer and
it will be able to eradicate the first order and will beep with a voice message that the
order of this customer has been changed
5. Delivery: It is a manual process which will be carried by drivers.
6. Collecting money from the customer
7. Reporting back to office: In this process when the driver reports back to the office then
the operator will click on his name and on the button in time then the system will
immediately notify his time and store it.
8. Calculation of number of orders per day: This will be calculated by the number of
orders delivered which is done when the driver enters his in and out time which means
that the order has been delivered the system will calculate the number of orders
delivered .
40 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
9. Sending statements and paying the money to the restaurants by checks: This is done
by the accountant when he checks that how many orders are delivered from which
restaurants which will be stored in the system.
People oriented: this consists of the following-
1. Receptionist will be the operator of the system she will take orders from the customers
and inform drivers and the restaurants.
2. Drivers the people who will deliver the orders
3. Restaurants manager
4. Waiters on wheels manager
5. Customers
6. Accountant will keep track of the accounts
Government agencies: government agencies include tax and service charge.
Operational feasibility seen through PIECES framework: The PIECES frame work helps
identify operational problems to be solved and their urgency. PIECES stand for:
Performance: Receiving customer order till delivering Order.
Information: How the information is passed from WOW – Driver - Restaurants
Economy: It is cost beneficial
Control: Installing password, firewall and antivirus , so that there is no unauthorized
access
Efficiency: System is time efficient and effective, providing the information on single
click
Services: System will provide desirable and reliable service to customer and end users
Economic feasibility: The economic feasibility underlies the whole system development effort.
We assume the Economic feasibility to analyze the cost of the project in order to know whether
41 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
it is worth spending to develop the system. The system that we are going to design is flexible and
less expensive which will provide immediate access to records that are only periodically updated.
Cost – benefit analysis
This to analyze,
The cost to develop the system
Which includes man power costs, and the technology used to build the system etc.
The business cost
If the system is developed then what will be its maintenance costs?
Economic feasibility as per system perspective: our system is economically beneficial because
it will save time and money by storing and transforming the data in an effective and efficient
way. End user will be able to inform restaurants and driver for the delivery directly by sending
message he will also be able to check out the availability of drivers, so he can save the cost of
telephone charges the system will be able to produce end of the day slip in which it will show
total sales and profit done by sales both weekly and daily, by this manager of WOW need not to
keep an accountant, this will save money.
Selection of methodology: we have selected structured system analysis and design
methodology. Structured analysis is one of the most popular methodologies that are being used
to define system specification. Because of problems faced in traditional system development life
cycle approach structured advancement have come up whose purpose is to provide more closely
controlled more industrious development surroundings. These include structured analysis and
design methodology along with structured programming. A structured approach to the analysis
and design of systems differs from the traditional SDLC approach where it calls for the systems
analyst to look beyond a physical view of the current system. The result of SDLC is generally
42 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
inflexible and unmaintainable system. This methodology uses logical process design. The
structured system development cycle consists of:
Structured methodology
Structured tools ,and
Structured process
Structured methodology: the structured methodology of systems analysis, analysis, design,
and implementation centers on building a logical model of the system in order to provide
systems analysts, programmers and users a common picture of the system and its
interrelationships.
Structured process: it provides clear understanding of the system to system analysts. It consists
of the following:
Objective: organization, scope, and schedule of new system.

Abstract
I have played the role of Physical designer and had contributed mainly in physical designing
of the project based on the logical design. Physical design is clearly mapped to the logic given
by logical designer. The main objective of the project is to identify the different framework of
activities associated with methodologies and describe how the techniques are used together to
develop a system using SSADM.

Introduction
Tom Bickford and Sue were two students in the college they always wanted to open their own
restaurant which should provide meal delivery service to the customers. They started the
restaurant “Waiter on Wheels” with very low initial investment in 1997 .When customer calls
waiter on wheels and places the order, then waiter on wheels will inform the related restaurant
for the order and send the driver to pick up the order from the restaurant and deliver it to
customer. There business was increasing day by day as customer liked their food delivery
services. Now as there was increase in number of customer’s waiter on wheels started facing
some problems to run their business.

System Development Life Cycle
Structures of SSADM
1. Feasibility Study – in this we decide which and what are the methods or techniques that
we can adopt , what will be the cost of the project and how much time will project take to
accomplish
2. Requirements Analysis – in this we analysis the requirements for our system, do we
have enough technology or resources to fulfill the client requirements.
3. Requirements Specification -- detailed functional and non-functional requirements are
identified and new techniques are introduced to define the required processing and data
structures.
4. Logical System Specification – for each and every project we need to have a logical
design so that we can get entire idea for the project and it will help in the implementation.
5. Physical Design -- a physical database design and a set of program specifications are
created using the logical system specification

Problems faced in existing system
Limited user involvement: There were very few people involved in running this meal
delivery system. They were having only one driver for the night shift, contract with only two
restaurants in that area. According to increasing demand of customers, they need to get more
drivers and contract with more restaurants in order to deliver the variety of food on time.
Inadequate resources & requirement: As initial investment in opening restaurant was quiet
less, they were not having adequate resources like delivery vehicles, mobile phones as waiter
on wheels was meal delivery service. They need to get more delivery motorcycles and
mobile phones so that they might contact with the driver on the way if there is any change in
order or driver has to pick the order form some other restaurant.
Business requirement have changed between commencement and deliverance: As waiter
on wheels was a meal delivery service which provides food from different related restaurants
and deliver it to customer at one place. As this delivery business started by only contract with
two restaurants and few customer. Customers were increasing day by day there was change
in business functions which lead to problems like they were not able to deliver orders on
time, not able to get in touch with the customer, delivering wrong order. Then they realized
to input computerized customer support system.
Absence of CASE support for analysis and design: Tom and Sue started waiter on wheels
without analyzing the current business situation and future planning .They didn’t do any
feasibility study before starting this meal delivery system which later on started causing them
problems.
Low level of involvement of users was due to lack on ownership and assurance of the
system: As there was low level of involvement in the entire delivery system, there were few
people involved in this business. Their business was running smooth with limited number of
52 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
customers and restaurants. But when the customer demand increased they were not able to
manage the business effectively.
Inadequate tools and techniques: For each and every business some tools and techniques
are required to run it in effective way .But in waiter on wheels they didn’t use any techniques
to run the business that was the reason why they were not able to manage their business
properly. When all things started messing up, then they realized to input some technique in
order to manage their business and implemented computerized customer support system
which will help them in managing the details of orders, customers and sales report etc…
Inadequate designing: As waiter on wheels was a restaurant they need to have a menu and
forms for the customers, so that customer can place the order easily. But they were having
nothing like that when customer calls to place the order they just tell the lists of items on the
phone and receive the order. But as per the customer needs they start designing the forms,
bills, menu cards for the ease of customer.
No updating of database management system: They do not keep track of the sales report,
drivers, customers, order.

Selecting the methodology
In this we have to select the methodology for our project i.e. Waiter on Wheels customer support
system. Basically there are two types of methodology used for the projects Structured System
Analysis and Design Methodology and Object Oriented Methodology.
SSADM stands for Structured Systems Analysis and Design Method. It was developed for the
stages of system analysis and design of system development. This method is most established
and widely adopted. SSADM uses a mixture of text and diagrams in system development life
cycle, from the starting of the project till physical design
SSADM is waterfall-based methodology. It flows like the waterfall starts from initial stage and
then moves forward step by step till reaches the goal state , if there are any changes to be made
it will again start from the first and then carry on with the entire task .
We have chosen Structured System Analysis and Design Methodology (SSADM) because this
methodology is very helpful to systems analyst. It makes sure that they are not floundering in
deep of complexity but can beneficially work on a system .This methodology often results in
method for each project; it provides a firm basis for project controlling and scheduling. The
project can be broken in several steps of the methodology and a variety of individuals and teams
can set different steps to perform their task. This makes it easier for the project manager to
estimate the duration and cost of the project.

Techniques used by SSADM
SSADM uses a combination of three techniques:
Logical Data Modeling
Data Flow Modeling
Entity Behavior Modeling
Investigation techniques
The investigation techniques are
Questionnaires
Interview
Survey
Studying Documentation
Observation
For our project I followed two investigation techniques from the among above listed i.e.
Interview
Studying Documentation
57 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
Interview:
As the project is concerned with the restaurant which provides service as home delivery I went to
some restaurants providing the same service as waiter on wheels and I conducted short interview
with manager of Dominos Restaurant to know what are the procedures tools and techniques
followed by them in order to run their restaurant effectively. This information was very helpful
throughout the project and also gave us idea about the meal delivery systems. After the interview
in Dominos I went to other restaurants to know about their current delivery system followed by
them. As I concluded form this that almost all the restaurants adopt same procedure and
techniques for the meal delivery system.
58 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
Studying Documentation:
In order to find some different delivery system I referred to many journals, magazines,
newspapers and internet, but there also I found almost the same system used by the restaurants.

Physical Design:
Physical design takes this logical design blueprint and produces the program specifications,
physical file or database definition and user interface for a selected target hardware and software.
These programs and files will fulfill the logical design requirements but may be subject to some
constraints and compromises.
Design objectives
The system is designed based on the objectives set for the new information system in the
strategic plan. Organizational objectives such as:
Increasing the business profit
Securing a larger market share
Improving customer service
60 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
There are three main objectives which the designer has to bear in mind while evolving and
evaluating design
Performance, how fast the design is secure against human error, machine hardware
resources
Control, the extent to which the design is secure against human errors, machine
malfunction, or deliberate mischief.
Changeability, the ease with which the design allows the system to be changes to, for
example meeting the user’s needs to have different transactions types processed.
Logical to physical design
Files or database: Based upon the entity-relationship model and supported by the entity
life history and the data dictionary
Processes and programs: Based upon the processes of the data flow diagram and
supported by the entity life history and data dictionary
Input and output: Based upon the flow of the data flow diagram and supported by the
data dictionary
Interfaces : Underpinned by understanding of requirements and skills level explored
within the context of the data flow diagram
Controls: Supported by the data flow diagram
61 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
On the basis of logical designing i.e. ER-diagram and data flow diagram I have designed the
forms that are required by our develop system to keep the records of customers, drivers, orders,
sales report and weekly reports for the convenience of waiter on wheel employees.

Conclusion
While doing this project I have concluded that system development life cycle (SDLC) is one of
the best ways to carry a project which also helps me in learning the skills of project management.
Among this there are seven phrases followed by a project manager or an organization to develop
the information system. One of the phases is designing under which logical and physical design
67 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
are mentioned. In physical designing I came to know how attributes and entities are related to
each other and finally to real life.

Analysis of the current system
The system on which we are working is a system on waiter on a wheel. Our system processes in
the following manners:
First, the customer call waiter on the wheel to place the order, herby waiter on wheel intimates
the restaurant and to the driver. The driver is responsible for the delivery. He takes up the order
from the restaurant and delivers to the customer address and takes the payment and hand over the
bill to the customers and after that he gets back to his waiter on wheels
Problems in existing current system
Since they are running the business on waiter on a wheel and have a tie up with other restaurant
so it is obvious that they will come up with many type of problem. No doubt they will have
benefit but at some point of time they will face some problems. The problems that they will face
are as follows:
1. Inadequate resources and requirement
2. Inadequate techniques
3. Inadequate designing and tools
4. Absence of CASE support for analysis and design
5. Updating of database management system
6. Low level of involvement of users was due to lack on ownership and assurance of the
system.
7. Business requirement have changed between commencement and deliverance.
Since there were many problems they might face so to sort out the above mentioned problems
there must be a proper solution. So we come up with the following solutions:
1. End of day deposit slips
2. Weekly rep[ort of restaurant
71 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
3. Sales report as per their device
4. Able to record order effectively and informing the user effectively
5. Inform drivers and restaurant at the click button
Feasibility report
Before I lay down the reports for the feasibility, we must be aware of the term feasibility.
Feasibility is defined as the viability of project feasibility does not solve any problem but it gives
a scope of solving problem.
The aim of feasibility report is to find out the problem of the current system and meet the end
user requirement.
Our feasibility reports consist of the following:
1. Technical feasibility
2. Operational feasibility
3. Schedule feasibility
4. Economics feasibility
Out here I will be reporting on technical feasibility. In this feasibility there are problems or
issues which have to be looked at. The issues are as follows:
Is the proposed system technology is practical
Does the organization currently possess the necessary technology
Does the organization possess the necessary technical expertise
And if the technology is not present then is it affordable by the organization.
Generally, the technology for the any defined solution is available. The question which should be
considered is whether that technology is mature enough to be easily applied to the problem.
Some firms like to use latest technology, but most of the firms prefer a mature and proven
technology .A mature technology has a larger customer base for obtaining advice concerning
problems and improvements.
72 | P a g eAsian Pacific University of Innovation and Technology
System Analysis and Design Waiters on wheels
Assuming that the solution’s technology is practical, the next step is to determine whether it is
available in the organization has the capacity to use it?
If the answer to nay of the above questions is no, then the possibility of getting it from outside
should be considered. If it is available outside, but is too costly for the organization to purchase
it, then the alternative that requires the technology is not practical and is technically infeasible.
Selecting the methodology
In this we have to select the methodology for our project i.e. Waiter on Wheels customer support
system. Basically there are two types of methodology used for the projects Structured System
Analysis and Design Methodology and Object Oriented Methodology.
We have chosen Structured System Analysis and Design Methodology (SSADM).

Screen 1: In the screen shot 1 we deal about the customer information. Here you can clearly see
that in the customer information we see that for every customer we have date, customer id, time,
customer name and customer address. When the customer places the order we keep record of all
the above information. First we note down the time and date at which the customer places the
order and give them a customer id. After that we jot down their address. This is all we have in
our screen shot 1

Screen4: Fourth screen deals with the transaction per day form. In this form all the details of the
daily transaction are mentioned. Transaction form consists of order detail, total number of order
placed in a day and total sale. In order detail all the details including the time at which it was
ordered, then the name of drivers and his id is written .the name of restaurant and total bill are
also mentioned. This helps them to maintain the record of their daily sales.
