1.0 - INTRODUCTION

In this project of ours, we have been given the task of making a system for an

event management company named Planit Event Management (Pvt) Ltd. The

management of the company has decided to invest in a new information

management system so that they can automate their office processes for work to

be done faster and efficiently.

There are different areas of the company that are going to be combined and

automated using thing system. The front office, the human resource office, the

stores where the inventory is kept, the accounts department and the management

are all going to be connected using this system.

The prototype system we are designing would be done using C#.net and we would

be using the SSADM methodology to develop the system and implement it.

The system would be mainly used by the staff and management of the company

only. No external personal would be using the system as it is an internal

information management system and allowing access to external people would

compromise the security of the system.

The system would handle all the inquiries by the customers, direct them to the

relevant officials, help in managing the events that the company is doing, help in

inventory management, payment process and create necessary reports for

management.

Page 10: System Development Methods

2.0 – ASSUMPTIONS

In this project, we have taken certain assumptions on how the processes work

manually and have implemented the same in the automated system. They are as

follows.

1. Each event managed by the company will be headed by one person called

the Event Manager who will have full control over everything that

happens in that particular event.

2. When a client makes an inquiry, depending on the type of inquiry

(consultation, event organizing, itinerary management etc.) the quotation

would take at least 24-72 hours to be prepared and sent to the customer.

3. If the company does not have adequate staff or do not have staff of a

particular type or do not provide a particular service in house (catering,

magicians for kids parties, security personal for events, etc.), they will be

obtaining the services of 3rd

party suppliers but all these will be going

through the company and not as external partners for the event.

4. At least 50% of the payment of the quoted amount has to be made prior to

the event and the balance depending on the final amount will have to be

settled after the event by the client.

5. The quotation would provide an estimated amount for the requirements of

the client while the final cost would change according to the changes in

plans and costs of the customers’ requirements while the event is being

planned.

3.0 – SELECTION OF METHODOLOGY

A good software project is the result of a proper structured development

methodology followed by all those involved in the project. Hence, we too decided

to use a recognized development methodology to handle our project. The

methodology we decided to use was the Structured System Analysis and Design

Methodology (SSADM).

3.1 - STRUCTURED SYSTEM ANALYSIS AND DESIGN

METHODOLOGY (SSADM)

SSADM was developed in the year 1980. It’s the standard design of information

systems in the United Kingdom. It breaks up a development project into stages,

modules, steps and tasks. The first model developed in SSADM is the data model.

The techniques used in SSADM are as follows.

1. Data Flow Modeling - It involves in data flow tracking in an information

system. This analyzes the data stores, process, external entities and data

movement clearly.

2. Logical Data Modeling - This engages with process identifying,

modeling and documenting data as a part of system requirement gathering.

And then data are classified further into relationships and entities.

3. Entity Behavior Modeling - This engages in identifying and

documenting the events influencing each entity and the sequence in which

these events happen.

3.1.1 – MAIN OBJECTIVES OF SSADM

1. Develop better and high quality systems.

2. Good communication between participants in a project by establishing a

framework.

3. Make projects resilient to the loss of staff.

4. Improve the project management and control.

Page 12: System Development Methods

4

5. Make use of experienced and inexperienced development staff more

effectively.

6. Allows projects to be supported by computer based tools as computer

aided software engineering systems.

3.1.2 – MAIN STAGES OF SSADM METHODOLOGY

1. Feasibility Study: It covers a large level analysis of business area to

conform whether the particular system is feasible to develop.

2. Requirement Analysis: In this stage, requirements are identified and

current business environment is modeled, business system options are

produced and presented. From these, one is chosen and refined. The

possible techniques that are used in this stage are Logical Data Modeling

and Data Flow Modeling.

3. Requirement Specification: In this stage functional and non-functional

requirements are specified as a result of the requirement analysis stage.

Data Flow Modeling, Entity Event Modeling and Logical Data Modeling

can be used as techniques.

4. Logical System Specification: In this stage implementation and

development environment are specified. The logical design of update and

enquiry processing and system dialogs are carried out.

5. Physical Design: In this technical specification and the logical design are

used to create physical design and set program specification.

It should be noted that in the SSADM methodology, Implementation and

Maintenance of the developed system are not part of the stages. Hence we will be

using the Traditional Software Implementation Methodology about which we

have specified in this documentation below.

3.1.3 – ADVANTAGES OF SSADM

1. It offers better understanding.

2. It’s highly practical.

3. Coherent design.

4. High Quality system is delivered at the end of project.

Page 13: System Development Methods

5

3.1.4 – DISADVANTAGES OF SSADM

1. It has a long development times because every stage must be completed

before moving on to the next stage.

2. It costs time and money, Organizations must have large resources.

3. Lack of user involvement.

4. It’s not flexible.

3.2 – IMPLEMENTATION STRATEGIES

We are developing a prototype of our system. Prototype is building process of a

system. It’s a repeating process which is a part of analysis phase of system

development life cycle. In the initial stage of analysis some uses papers to get user

feedbacks and later on develop a prototype using fourth generation languages like

visual basic during the design stage.

There are many forms of prototyping -From low tech sketches or paper screens,

which users and developers can paste controls and objects. To high tech

operational systems CASE(computer aided software engineering).

There are many Advantages of Prototyping

It requires user involvement

It results in high user satisfactions.

It reduces development costs.

It reduces development time.

And there are some disadvantages also

Developers may become too attached to their prototypes.

It sometimes guide to incomplete documentation.

It can guide to insufficient analysis.

4.0 – PROBLEM ANALYSIS OF CURRENT SYSTEM

PLANIT Event Management (Pvt) Ltd is a large and successful event planning

company that has decided to invest in a new information management system.

This system is to allow for better information management. The following

problems have been noted in the current existing system.

1. The system currently maintains all its records manually I hardcopy form

and none of the process is automated at all. This leads to slower and a lot

of wasted resources in attempting to maintain the system and in trying to

keep all the records up to date.

2. There is a great risk of information being misused by people who should

not be allowed to view it. This problem is slightly improved by keeping all

the records in storage closets with locks. This feature can be easily

breached and also careless oversight on the part of the employee where

records re forgotten to be locked up after use.

3. Threat of records being destroyed easily. Since all records are maintained

in hardcopy format there is a really great possibility of the information

being ruined by factors beyond human control like water damage and the

possibility of harmful products accidently falling on to the records. The

possibility also exists that an external party may remove pages from the

legers containing the information.

4. Another threat faced by the current system is the threat of incorrect

information being entered into the system by accident. This is a great

threat as its only human to make mistakes and taking into consideration

the large amount of information passing through the company, it is

possible that a mistake might go unnoticed until it’s too late to correct it or

the damage is permanent. This will add to additional costs to the company

when it tries to rectify its errors.

5.0 – OVERVIEW OF THE PROPOSED SYSTEM

5.1 – FUNCTIONAL SPECIFICATIONS

Our team has been asked to develop a system for PLANIT Event Management

(Pvt) Ltd, Colombo. The system that has been requested is an information

management system. This system has several primal requirements that have been

requested for by the Management of PLANIT.

The Basic Requirements are as follow:

1. Manage Front Office

2. Managing of Events

3. Procurement and inventor Management

4. Payment Management

5. Managing of Employees

6. Monitoring Reports

In developing the new system our team took extreme care to ensure that the above

mentioned five basic requirements are met exactly as the client had requested.

5.1.1 – MANAGING FRONT OFFICE

This is where the customer of the company will make his initial request for

assistance in organizing the event. The front desk will be the point of contact for

the customer with the company. Here there are several processes that can be

carried out.

Registration of the customer – This will be the initial step. The customer

will provide all the required information to the front office and this

information will be saved in the company records.

Reservation – Here the customer will provide all the details of the event

and this information will be cross checked against the availability and the

customer will be told if the company is able to cater to the request.

Page 16: System Development Methods

8

Cancelation – In the event that the customer wishes to cancel his or her

event the customer will again inform the front office and the front office

will cancel the event and the appropriate charges will be applied.

5.1.2 – MANAGING OF EVENTS

The management of the events is a vital part in this organization. It mainly

will deal with customer in the event that the customer wishes to change

retails regarding the event.

The allocation of the event planner or the event manager will also be done

here. The system will check its records and allocate the most suited and

available planner to an event wen the customer makes the request.

5.1.3 – PROCUREMENT AND INVENTOR MANAGEMENT

This segment of the system will deal with the handling of the companies supplies

and the resources that will be outsourced. The system will check within itself for

records of the utilization of the company’s products and inform the system user if

the company has enough equipment on its own to provide for the event.

Procurement of supplies from outside dealer will also be done in the event that the

company does not have the required resources or when the company has depleted

its own resources.

5.1.4 – PAYMENT MANAGEMENT

The payments due for handling the event will also be provided to the customer at

this point. The customer will receive an invoice to which they are then expected

to provide the relevant payments.

Further the customer will provide information such as the method of payment and

the payment scheme. At the payment point the customer will also be given

information such as if he will be receiving a discount.

5.1.5 – MANAGING EMPLOYEES

For a successful event to be organized the key requirement is proper management

of resources. Staff is one such vital resource and the management and the

Page 17: System Development Methods

9

allocation of the staff for the events will be carried out from this point of the

system.

New employees can be added and existing employee information can be changed

or permanently removed.

5.1.6 – MONITORING REPORTS

The reports will be generated by the system as a method of overseeing the work

that has been happening throughout the company. This information will only be

available to the administrative staff of the company and the management.

There will be five different reports generated by the system for the use of the

management.

1. Monthly and Annual Reservation Reports

2. Low Supplies Report and Free Supplies Report

3. Staff event Report

4. Income and Expenditure Report and Profit and Loss Report

5. Cancelation Report

Each of these will be generated by the system and presented to the administrative

user. This way the administration of the company can keep a close watch on all

the activities in the company and make changes as and when the situation

demands it.

Page 18: System Development Methods

10

5.2 – NON – FUNCTIONAL SPECIFICATIONS

The user of the new system has requested for several non-functional

specifications to be present in the system that is being developed.

Performance – The system will have to be able to perform all of its tasks

fast and efficiently. One of the main reasons for incorporating the new

system was in order that the time spent on manual processing of the

information received can be cut down. The system will also have to be

user friendly so that the user of the system will not find the using of this

system more tedious that the manual maintenance of the same system.

Security – This was a major concern for the senior management of the

company as the previous system’s lack of security. The system was unable

to effectively safeguard the information of its clients and the details of the

events and other sensitive information. Therefore this system will

incorporate several levers of access granting people access to only what

information they have the right to view. Other people without access will

therefore be safely prevented from viewing the system.

Reliability – It is vital for the system to be reliable. It should not fail at

critical points and that checking mechanisms be implemented to prevent

the entry of wrong data as much as possible. This is done with validation

checks and other such features. Though this will not completely prevent

wrong details from accidently being entered it will prevent information of

the wrong format to be entered.

Usability - For an effective system to be developed the system will also be

usable and flexible for change. During the development of the system our

team has tried as much as possible to make the system flexible for future

change.

12.0 – DEVELOPMENT ENVIRONMENT

While designing the system, we as a team thought in terms of developing this

system in the future too so that it can be successfully implemented once the

development it done completely. Keeping in mind the knowledge of the team

members of the project and the clients requirements we decided to develop the

system in the following methods.

12.1 – LANGUAGE OF PROGRAMMING

All 3 members of the group were well versed in Visual Basic.net, C

Programming, C++ Programming, Java Programming and C# Programming. And

after much discussion, we unanimously decided to develop the system in C# since

we have not previously developed a fully-fledged system in that language as well

as taking on the project as a challenge to test our knowledge in this language.

12.2 – PROGRAMMING TOOLS

All three members of the group were well accustomed to use and program using

Microsoft Visual Studio 2010 and since we decided to go ahead using this IDE

software tool to develop the system too. We would be using the Microsoft .Net

Framework 4.0 as it is one of the latest standards in the industry.

12. 3 – DATABASE

Since it is an obvious fact that a system of this magnitude needs to be linked with

a server to store and retrieve data from, we decided to use the Microsoft SQL

Server 2008 for this purpose. The integration between Ms SQL Server and Ms

Visual Studio 2010 is very close; it would be easy to work with this database

technology. Also the security concerns were looked into when the decision was

made.
