1. Operations Management
Why Operations Management?
Every aspect of business revolves around operations. There is a significant amount
of interaction and collaboration amongst the functional areas of finance, operations and
marketing. Operations Management enables us to solve complex business problems
related to the journey of products and services from the manufacturer or provider to the
end customer. Help us gain an understanding of the techniques required for managing
and improving the integration of design, resources, processes and customer
requirements.
Operations Management can be defined as the management of systems or
processes that create goods and provide services. The purpose of the operations function
is to add value during the transformation process.
Goods are physical items that include raw materials, parts, subassemblies, and final
products e.g. Automobile, Computer, Oven, Shampoo
Services are activities that provide some combination of time, location, form or
psychological value e.g. Air travel, Education, Haircut, Legal counsel
The scope of operations management ranges across the organization. The
operations function includes many interrelated activities such as:
Forecasting
Capacity planning and Scheduling
Managing inventories
Assuring quality
Locate Planning etc.

Decision Making
Most operations decisions involve many alternatives that can have quite different
impacts on costs or profits. Typical operations decisions include:
What: What resources are needed, and in what amounts?
When: When will each resource be needed? When should the work be
scheduled? When should materials and other supplies be ordered?
Where: Where will the work be done?
How: How will the product or service be designed? How will the work be
done? How will resources be allocated?
Who: Who will do the work?
Decision Area What the Decisions Affect
Product and service design Costs, quality, liability, and environmental issues
Capacity Cost, structure, flexibility
Process selection and layout Costs, flexibility, skill level needed, capacity
Work design Quality of work life, employee safety, productivity
Location Costs, visibility
Quality Ability to meet or exceed customer expectations
Inventory Costs, shortages
Maintenance Costs, equipment reliability, productivity
Scheduling Flexibility, efficiency
Supply chains Costs, quality, agility, shortages, vendor relations
Projects Costs, new products, services, or operating systems
The primary function of the operations manager is to guide the system by decision
making.

2. FORECASTING
Demand Forecasting can be defined as a process to estimate sales and use of
products so that they can be purchased, stocked or manufactured in advance to meet the
demand at the right time. The primary goal operations and supply chain management is
to match supply to demand. A demand forecast is essential for determining how much
supply will be needed to match demand.
The forecasting can be broadly classified into the following:
1. Quantitative method: Quantitative forecasting methods are used when we have the
past information of the variable which can be quantified and assumed to follow the same
pattern over the future for example the prediction of quarter sales volume. The demand
forecasting tools for such analysis are the time series method and the causal method.
2. Qualitative method: If the historical data is unavailable or is deemed unfit to
extrapolate, we use qualitative method. For example, phasing out subsidies on LPG can
raise questions about the validity of past data to use for future LPG sales prediction.

Optimum 6
Delphi method, Expert Judgment, Scenario Writing and Intuitive Approaches are the
popular method used for Qualitative analysis.
3. Time series method: As discussed above, times series method make prediction based
on a set of observations on a variable measured at successive points in time and over
successive periods of time. This historical data forms a time series. A time series has four
components which are trends, cyclical, seasonal and irregular. Trend component of a time
series depicts the long term gradual shift to a higher or lower value. The cyclical
component captures the recurring sequence of points above and below the trend line
which lasts more than one year. The seasonal component is the regularly repeated
pattern which can be attributed to seasonal influences. The irregular component
accounts for the deviations of the actual time series values from those expected given the
effects of trend, cyclical and seasonal component.
Based on the above components, following forecasting methods are devised:
Smoothing Methods: It is used to smooth out the random fluctuations caused by the
irregular component of the time series. These methods are appropriate for stable time
series i.e. which does not have a seasonal, trend or a cyclical component. There are three
ways in which it can be done. First is the moving average method which uses the average
of the most recent n data values in the time series as forecast for the next period.
Weighted average method assigns different weightage for each data values and computes
the weighted average of the most recent n values as the forecast. The weights can be
assigned based on the accuracy of data for a particular period of time. Exponential
smoothing uses weighted average of past time values as the forecast. It is a special case
of weighted average where we assign only one weight to the most recent observation
and the weights for other observation is automatically calculated(the sum of weights is
always 1) and become smaller as the observation moves farther into the past.
Trend Projection: They are used to forecast a time series which have long term linear
trend which is not stable and hence smoothing methods cannot be applied.
Trend and Seasonal Components: This forecasts a time series that has both trend and
seasonal components. It involves removing of the seasonal effect which is done by
deseasonalizing time series and applying regression analysis on the deseasonalized data
to estimate trend.
Causal Method: Causal forecasting methods are based on the assumption that the
variable we are forecasting has a cause effect relationship with one or more than one
independent variables. For example, sales volume (dependent variable) for many
products is influenced by advertising expenditures. For this, regression analysis may be
used to develop the relation between the dependent and independent variables and we
can make a forecast by substituting the values of the independent variables in the
regression equation. Regression analysis in which the independent variables are
previous values of the time series is referred to as autoregressive models.

The better forecasts are, the more able organizations will be to take advantage of
future opportunities and reduce potential risks. A worthwhile strategy is to work to
improve short-term forecasts
Accurate up-to-date information can have a significant effect on forecast accuracy:
o Prices
o Demand
o Other important variables
Reduce the time horizon forecasts have to cover
Sharing forecasts or demand data through the supply chain can improve forecast

5. Process Selection
The main issue in designing process layouts concerns the relative placement of the
departments. A major objective in designing process layouts is to minimize transportation cost,
distance, or time.
The five key decisions in process management are:
I. Process Choice
II. Vertical Integration
III. Resource Flexibility
IV. Customer Involvement
V. Capital Intensity
These decisions are critical to the success of any organization and must be based on
determining the best was to support the competitive priorities of the enterprise.
Process selection
It refers to the deciding on the way production of goods or services will be
organized. It has major implications for
Capacity planning
Layout of facilities
Equipment
Design of work systems
Process selection criteria
Variety
Volume
Equipment Flexibility
Process Choice
The first choice typically faced in process management is that of process choice.
Manufacturing and service operations can be characterized as one of the following:
1. Project: A project process is characterized by a high degree of job customization, the
large scope of each project, and the release of substantial resources, once a project is
completed. E.g. building a shopping center, planning a major event, running a political
campaign
2. Job Shop: A job shop process creates the flexibility needed to produce a variety of
products or services in significant quantities. Customization is relatively high and volume
-
Optimum 13
for any one product or service is low. E.g. custom metal processing shop, hospital
emergency rooms
3. Batch Flow: In a batch flow process same or similar products or services are provided
repeatedly with a narrower range of products or services. Variety is achieved more
through an assemble-to-order strategy than the job shops make-to-order strategy. A
third difference is that production lots or customer groups are handled larger quantities
(or batches) than they are with job shop processes. E.g. scheduling air travel,
manufacturing garments, furniture manufacturing
4. Line Flow: A line flow process lies between the batch and continuous processes,
volumes are high, and products or services are standardized, which allows resources to
be organized around a product or service. E.g. automobiles, appliances, fast-food
restaurants.
5. Continuous Flow: A continuous process is the extreme end of high-volume,
standardized production with rigid line flows and tightly linked process segments. Its
name derives from how materials move through the process. E.g. petroleum refineries,
chemical plants
Layout is the configuration of departments, work centers, and equipment, with
particular emphasis on movement of work (customers or materials) through the system
Facilities layout decisions arise when:
Designing new facilities
Re-designing existing facilities
Basic Layout Types
Product layouts: Product layouts arrange activities in a line according to the
sequence of operations that need to be performed to assemble a particular
product
Process layouts: Process layout that groups similar activities together in
departments of work centers according to the process or function that they
perform characteristic of operations that serve different customers different
needs
Fixed-Position layout: Fixed-Position layouts are layouts are used in projects in
which the product is too fragile, bulky, or heavy to move. E.g. ships, houses, aircraft
Combination layouts
FMS (Flexible Manufacturing System): A group of machines designed to handle
intermittent processing requirements and produce a variety of similar products
-
Optimum 14
CIM (Computer Integrated Manufacturing): A system for linking a broad range of
manufacturing activities through an integrated computer system
Line balancing: The process of assigning tasks to workstations in such a way that the
workstations have approximately equal time requirements.
Why is line balancing important?
It allows us to use labor and equipment more efficiently.
To avoid fairness issues that arise when one workstation must work harder
than another.
Scheduling:
It establishes the timing of the use of equipment, facilities and human activities in
an organization.
Sequencing
Determine the order in which jobs at a work center will be processed
Priority rules for sequencing
Simple heuristics used to select the order in which jobs will be processed
FCFS - first come, first served
SPT - shortest processing time
EDD - earliest due date
CR - critical ratio
S/O - slack per operation
Rush emergency
Queuing theory - Mathematical approach to the analysis of waiting lines
Littles Law
For a stable system the average number of customers in line or in the system is equal to
the average customers arrival rate multiplied by the average time in the line or system
Options for reducing wait times:
Work to increase processing rates, instead of increasing the number of servers
Use new processing equipment and/or methods
Reduce processing time variability through standardization
Shift demand

Optimum 15
6. Facility Layout
Location decisions arise for a variety of reasons:
Addition of new facilities
1. As part of a marketing strategy to expand markets
2. Growth in demand that cannot be satisfied by expanding existing facilities
Location decisions are based on:
Profit potential or cost and customer service
Finding a number of acceptable locations from which to choose
Position in the supply chain
Web-based retail organizations are effectively location independent
Supply chain management issues such as supply chain configuration
Service and Retail Location Considerations:
Nearness to raw materials is not usually a consideration
Customer access is a
Prime consideration for some: restaurants, hotels, etc.
Not an important consideration for others: service call centers, etc.
Tend to be profit or revenue driven, and so are
Concerned with demographics, competition, traffic/volume
patterns, and convenience
Evaluating Location Alternatives
Locational cost-volume-profit analysis: Technique for evaluating location choices in
economic terms. The steps involved in this analysis are:
Determine the fixed and variable costs for each alternative
Plot the total-cost lines for all alternatives on the same graph
Determine the location that will have the lowest total cost (or highest profit)
for the expected level of output
Factor rating analysis: General approach to evaluating locations that includes
quantitative and qualitative inputs. The procedure for the analysis is as follows:
Determine which factors are relevant
-
Optimum 16
Assign a weight to each factor that indicates its relative importance compared
with all other factors.
Decide on a common scale for all factors
Score each location alternative
Calculate weighted factor sum for each alternative
Choose the alternative that has the highest composite score
Center of gravity method: Method for locating a distribution center that minimizes
distribution costs
Treats distribution costs as a linear function of the distance and the quantity
shipped
The quantity to be shipped to each destination is assumed to be fixed
The method includes the use of a map that shows the locations of destinations
The map must be accurate and drawn to scale
A coordinate system is overlaid on the map to determine relative locations
Transportation model: It involves finding the lowest-cost plan for distributing stocks of
goods or supplies from multiple origins to multiple destinations that demand the goods.

7. Quality Management
Quality is a strategic imperative for organizations where customers are very
concerned with the quality of goods and services they receive. It is a never-ending journey
where most organizational members understand and buy into this idea.
Customer satisfaction customer loyalty
Quality needs to be incorporated throughout the entire supply chain, not just the
organization itself. Quality is the ability of a product or service to consistently meet or
exceed customer expectations
Determinants of Quality
Design
Conformance to Design
Ease of Use
After-Sale Service
Costs of Quality
Failure Costs: Costs incurred by defective parts/products or faulty services.
Appraisal Costs: Costs of activities designed to ensure quality or uncover defects
Prevention Costs: All TQ training, TQ planning, customer assessment, process
control, and quality improvement costs to prevent defects from occurring
Total Quality Management

8. Supply Chain Management
Supply Chain
It is the sequence of organizations - their facilities, functions, and activities - that
are involved in producing and delivering a product or service. It is also referred to as
value chains.
Supply Chain Management (SCM)
The strategic coordination of business functions within a business organization and
throughout its supply chain for the purpose of integrating supply and demand
management
Effective supply chains are necessary for organizational success
Requires integration of all aspects of the chain
Supplier relationships are a critical component of supply chain strategy
Lean operations and six sigma are being employed to improve supply chain
success
The goal of SCM is to match supply to demand as effectively and efficiently as possible

The Bullwhip Effect
The bullwhip effect can be explained as an occurrence detected by the supply
chain where orders sent to the manufacturer and supplier create larger variance then the
sales to the end customer. These irregular orders in the lower part of the supply chain
develop to be more distinct higher up in the supply chain. This variance can interrupt the
smoothness of the supply chain process as each link in the supply chain will over or
underestimate the product demand resulting in exaggerated fluctuations.

Optimum 22
9. Inventory Management
Inventory refers to goods and materials that a business holds.
Why is inventory required?
Maintaining inventory is important to keep service time and lead time in check.
Differences in lead times of individual machines and fluctuations in demand, supply and
movements of goods necessitates maintain buffer inventory. At the same time placing
orders in bulk has economies of scale from both ordering and logistical aspects.
Problems with inventory:
Maintaining inventory involves holding costs like warehouse costs, store keeping
costs, cost due to damaged, deteriorated and obsolete goods.
Inventory management:
Inventory management is basically about what to keep, where to keep and how
much to keep. It involves determining the optimum level of inventory by comparing the
costs of too less with the cost of excessive inventory. Inventory may exist at various stages
of the supply chain- warehouse, in-process, dealer, distributor and retailer. Inefficient
inventory management ties-up cash and leads to supply chain inefficiency.
Although its sounds very simple, Inventory management can make or break
companies. Increasing size, global suppliers, geographically spread stores, warehouses
and factories have forced some of the worlds biggest and the best companies to focus all
their might towards inventory management. This is simply because managing inventory
can help them improve their bottom-line, improve customer response time by reducing
lead times and maintain quality levels.
Improving inventory processes can offer significant cost reduction and customer
satisfaction benefits
Types of inventory:
Raw material inventory
Work-in-process inventory
Finished goods inventory.
Just-In-Time (JIT): This is the most important widely used method of managing
inventory. In this system, companies plan to receive items as they are needed rather than
maintaining high inventory levels, and materials requirement planning, which schedules
material deliveries based on sales forecasts.
-
Optimum 23
Inventory Costs
Holding (carrying) costs
Cost to carry an item in inventory for a length of time, usually a year
Ordering costs
Costs of ordering and receiving inventory
Shortage costs
Costs resulting when demand exceeds the supply of inventory; often
unrealized profit per unit
Basic EOQ Model (Economic Order Quantity)
used to find a fixed order quantity that will minimize total annual inventory costs
Economic Production Quantity (EPQ)
Economic production quantity (EPQ) is the quantity of a product that should be
manufactured in a single batch so as to minimize the total cost that includes setup costs
for the machines and inventory holding costs.
Reorder point
When the quantity on hand of an item drops to this amount, the item is
reordered.
Determinants of the reorder point
1. The rate of demand
2. The lead time
3. The extent of demand and/or lead time variability
4. The degree of stockout risk acceptable to management

11. Theory of Constraints
The purpose of Theory of Constraints (TOC) is for an organization to be an ever
flourishing company which aims at continuously increasing its value for all its stakeholders
(employees, clients and shareholders) now and in the future by capitalizing on a decisive
competitive edge in the market. For this, TOC principle follows the strategy of Build,
Capitalize and sustain the decisive competitive edge (DCE) in such a manner that it
satisfies the significant needs of significant customers which no other significant
competitor can match. The DCEs that the market demands are: Quality, Price,
Reliability and Responsiveness. TOC focuses on building a strong DCE on reliability and
responsiveness.
TOC states that a supply chain is no stronger than its weakest link. TOC tries to identify
the weakest link to thereby improve upon productivity of the entire supply chain. The
Five focusing steps of Theory of Constraints are:
1. Identify the system's constraint (The bottleneck the set of operation/s which
gives the least amount of output). This is recognized as the drum which run the
entire operations.
2. Exploit the system's constraint (Create Buffer before the Constraint to ensure
maximum exploitation of the system constraint).
3. Subordinate other processes to the above decision (A rope which ties all the
operations activity to the above decision).
4. Elevate the system's constraint (make necessary changes required to improve the
capacity of the constraint).
5. If in the previous steps, a constraint has been broken go back to step 1.
The Theory of constraints can thus be reduced into three steps i.e. Drum-Buffer-Rope
(DBR). This process is used to improve the throughput of the entire system thereby
helping the organization build upon a DCE of higher responsiveness and reliability. The
theory was introduced by Eliyahu M. Goldratt.
He later went to construct a Simplified-Drum-Buffer-Rope which resolved the problem of
shifting constraints (as we went through the process of Five Focussing Steps we realize
that the bottleneck has shifted in the supply chain link creating a problem of shifting
contraints/bottlenecks). This move stated that instead of identifying a constraint we can
fix the constraint The Market demand.
The process of capitalizing and sustaining the decisive competitive edge is done through
a process called POOGI (Process of on-going improvement). This is done in such a fashion
that no significant competitor can match the DCE that the organization has built on.

12. Project Management
Project management is the discipline of planning, organizing and managing
resources to bring about the successful completion of specific project goals and
objectives.
Objectives of Project Management
Make strategic business decisions
Control the minute detail that is necessary to finish projects
Understand current resource demands, set priorities, and evaluate long-term
staffing requirements
Use skilled resources effectively
Reorganize projects
Process of project management is guided by three key principles:
Planning
Controlling
Managing
Planning a project
The first step in project management is to define your project.
1. What is the scope of the work? What activities will make up the project and what
is their relationship to each other? Youll also want to identify the major
milestones that will help you monitor the projects progress.
2. What is the project duration? What are the dates when the project will begin and
end?
3. What resources are available to the project? Beyond labor, think about all the
types of resources you will require.
4. Who will perform what tasks? Determining your labor resources and their
available work hours is a key part of building a successful project. Youll need to
plan for downtime and holidays and determine the regular workweek for various
staffing types.
-
Optimum 29
5. How much will the project cost? What are the costs per resource? Are there any
hidden project costs?
6. What is the estimated budget? Establishing a project budget estimate in advance
helps you monitor possible cost overruns.
The answers to these questions form the framework of your project.
Controlling a project
Once you have built your project and estimated your budgeting needs, you save
this original plan as a baseline, or target schedule, to help you control the project. A
baseline provides a solid point of reference as your schedule changes over time. It allows
you to compare the original schedule to the current one and identify significant changes
and develop contingency plans.
You control a project to keep it heading in the right direction. Youll want to track
work progress and costs, compare them to your baseline, and then recommend what
actions should be taken.
Effective project control reaps many benefits. It allows you to keep a close eye on
possible problems before they become critical. It lets the project team and senior
management view cost and scheduling timeframes based on the reality of the schedule.
Managing a project
The process of guiding a project from start to finish is the responsibility of a
project manager. A good project manager wears many hats, acting at various times as a
motivator, communicator, coordinator, and advisor. As you control the projects progress,
it is your job to keep your team aware of changes to the schedule and possible
consequences. In many ways, you are the projects ambassador, ensuring that your
project organization is carrying out its responsibilities for the best possible outcome.
To be an effective project manager also requires consistency when you update
your projects. Select a day each week, or biweekly, when you will regularly update
projects. This regular update will include progress on values such as
Dates on which activities started or finished
Dates when resources are consumed
Changes to resource rates
Determine a standard policy for the update and scheduling procedure, and for
reporting progress.

13. Logistics Management
Logistics is complementary to Supply Chain. While Supply Chain management deals with
the flow of various materials/information/money from one partner to other, logistics is
the medium for facilitating this transfer.
Logistics Management can hence be defined as the task of coordinating material flow and
information flow across the supply chain.
Logistics were initially employed by one of the authors of military theory, Baron Antoine
Henri Jomini (1779-1869), a French general. According to him, Logistics was a theory of
movement, provisioning and accommodation of armies. After World War II, logistic
activities were extended for the solution of analogical problems in civilian use which
paved the way for the beginning of Business Logistics.
The institute of Logistics defines Logistics as ensuring the availability of
the right product,
in the right quantity and
right condition,

14. MRP and ERP
Material Resource Planning (MRP): It is an approach to inventory planning,
manufacturing scheduling, supplier scheduling, and overall corporate planning. The
material requirements planning (MRP) system provides the user with information about
timing (when to order) and quantity (how much to order), generates new orders, and
reschedules existing orders as necessary to meet the changing requirements of
customers and manufacturing.
MRP Inputs
Master schedule: It states which end items are to be produced, when these are
needed, and in what quantities. It should cover a period that is at least equivalent
to the cumulative lead time
Bill of Materials (BOM): A listing of all of the raw materials, parts, subassemblies,
and assemblies needed to produce one unit of a product
Inventory records: Includes information on the status of each item by time
period, called time buckets. Information about
Gross requirements
Scheduled receipts
Expected amount on hand
Cumulative lead time
The sum of the lead times that sequential phases of a process require, from ordering of
parts or raw materials to completion of final assembly.
MRP processing takes the end item requirements specified by the master schedule and
explodes them into time-phased requirements for assemblies, parts, and raw materials
Lot sizing
Choosing a lot size for ordering or production
Common lot sizing rules:
Lot-for-Lot (L4L) ordering
Economic Order Quantity (EOQ)
Fixed Period Ordering
