PRODUCTION &
OPERATIONS MANAGEMENT
PRODUCTION
• The Process by which raw materials & other inputs are converted into finished products.
• Production is the creation of goods and services.
• Production means application of processes to the raw material to add the use and economic values to arrive at desired product by the best method, with out sacrificing the desired quality.
Production & Manufacturing
Manufacturing refers to the process of producing only tangible goods.
Production includes the creation of both tangible goods & intangible services.
Angles of Manufacturing Function
1.Production as a System
2.Production as an Organizational Function
3.Decision Making in Production
Production as a System
a)Production System
b)Conversion Sub- System
c)Control Sub- System
Production System Concepts• Production System: A system which
converts a set of inputs into a set of desired outputs.
• Conversion Sub- System: A sub-system of the larger production system where, inputs are converted into outputs.
• Control Sub- System: A sub-system of the larger production system where, a portion of the output is monitored for feedback signals to provide corrective action.

Production as an Organizational Function
• Conversion Sub- System is the Core/ Heart of Production System.
• Every Organization irrespective of its purpose, has a production function where departments and personnel play a central role in achieving the objectives of the organization.
Decision Making in Production
General Categories Of Decision Making:-
1. Strategic Decisions : Relating to products, processes & manufacturing facilities.
2. Operating Decisions : Relating to planning production to meet demand.
3. Control Decisions: Relating to planning & controlling operations, these decisions concern the day-to-day activities of workers, quality of products & services, production & overhead costs & maintenance of machines.

Production Management
Production Management refers to the application of management principles to the production factory.
It involves application of planning, organizing, directing, & controlling to the production process.
Production management is defined as
management function which plans,
organizes, coordinates, directs and
controls the material supply and
Processing activities of an enterprise,
so that specified products are
produced by specified methods to
meet an approved sales programme.

OPERATIONS MANAGEMENT
Productive systems are those that convert or transform resource inputs into useful goods & services as outputs. Such productive systems are generally referred to as Operations Systems. POM relates to the management of such systems.Operations Management is the conversion of inputs into outputs, using physical resources, so as to provide the desired utilities.
Difference Between Production Management & Operation Management
1. PM is more used for a system where tangible goods are produced, OM is more frequently used where various inputs are transformed into intangible services.
It Covers Service organizations such as Banks, Airlines, Utilities, Production Control Agencies, Super Bazars, Educational Institutions, Libraries, Consultancy firms & Police Depts.2. Evolution of the Subject. i.e. PM precedes OM in the historical growth of the subject.

Technology6. The Service Revolution
The Industrial Revolution
• Production System prior to 1700s are referred to as the Cottage System
• From 1770- early 1800- England• 2 Major Developments:a) Substitution of machine power for human
powerb) Establishment of the factory system• Advanced further with the development of the
Gasoline engine and Electricity in the 1800s• Cottage System of production had been
replaced by the Factory System• Missing…..? Management
Scientific Management
A Philosophy which was propounded by business leaders, consultants, Educators and researchers.Contributors:1. F.W. Taylor-time study, methods
analysis,standards,planning & control2. Frank B. Gilbreth-motion
study,methods,construction,contracting, consulting,
3. Lillan M. Gilbreth-fatigue studies,human factor in work,employee selection & training
4. Henry L. Gantt-incentive,humanistic approach,training
5. Carl G. Barth-math analysis,consulting to automobile ind
6. Harrington Emerson-principles of efficiency7. Morris L. Cooke-SM its application to education &
govt.
Essential Principles
1. Developing a science for each element of a person’s work which would replace the old Rule-of-Thumb method
2. Selecting workers scientifically & training and developing them
3. Cooperating with workers to ensure that the work is done according to the principles of science that have been developed
4. Dividing work & responsibility equally between management & workers
The Human Relations Movement
Refers to the ways in which managers interact with their employees.Better work done by the employees, organization has an effective human relationsWhen morale & efficiency deteriorates, human relations are said to be ineffective.Factory workers- uneducated, in disciplined, unskilledFactory managers developed rigid controls to force the workers to work hard-1800s-early 1990s
Operations Research
Characteristics1. Approaches problem solving & decision
making from the total systems perspective2. Draws on techniques from varied disciplines
& applies the appropriate technique from each field to the system being studied
3. Does not experiment with the system but constructs a model of the system
4. Primary focus is in decision making5. Computers are used extensively
Computers & Advanced Production Technology
In the beginning computers were used
for clerical duties- payroll, billing cost
reports, inventory transaction etc..
Today- used as Decision Support

Operations Strategy
• Strategy is an organization’s action plan to achieve the mission. Each functional area has a strategy for achieving it’s mission & for helping the organization reach the overall mission.
• These strategies exploit opportunities & Strengths, neutralize threats and avoid weaknesses.
• It is concerned with setting broad policies & plans for using the resources of a firm to best support its long term competitive strategy.
• It involves a decisions that relate to the design of a process & the infrastructure needed to support the process.
• Operational strategies can be viewed as a part of a planning process that coordinates operational goals with those of the larger organization. Since the goals of the larger organization change over time, the operations strategy must be designed to anticipate future needs.
• Firms achieve missions in 3 conceptual ways:1. Differentiation2. Cost Leadership3. Responsei.e., operations managers have to deliver goods & services that are a)Better or at least different, b) cheaper, c) more responsive
Ten Strategic OM Decisions
•Differentiation•Low Cost•Response
Can be achieved when managers make effective decisions in 10 areas of OM
These are collectively called
as Operations Decisions
1. Goods & service design: Transformation ProcessDetermines Cost, Quality & Human
Resource Decisions Designs determine the lower limits of cost
& the upper limits of quality
2. Quality:The customer’s quality expectations must
be determined & policies & procedures established to identify & achieve that quality
3. Process& Capacity Design:Process options are available for products & services. Process decisions commit management to specific tech, quality, HR use & maintenance. These expenses & capital commitments determine much of the firm’s basic cost structure.4. Location Selection:Facility location decision for both manufacturing & service organizations may determine the firm’s ultimate success. Errors made at this juncture may overcome other efficiencies.
5. Layout Design:Material flows, capacity needs, personnel levels, technology decisions & inventory requirements influence layout.
6. Human Resources & Job Design:People are an integral & expensive part of the total system design. Therefore, the quality of work life provided, the talent & skills required & their costs must be determined.
7. Supply Chain Management:Determine what is to be made & what is to be purchased. Consideration is given to quality, delivery & innovation at a satisfactory price. Mutual trust between buyer & supplier is necessary for effective purchasing.
8. Inventory:These decisions can be optimized only when customer satisfaction, suppliers, production schedules & HR planning are considered.
9. Scheduling: Feasible & efficient schedules of production must be developed; the demands on human resources & facilities must be determined & controlled.
10. Maintenance:Decisions must be made regarding desired levels of reliability& stability, & systems must be established to maintain that reliability & stability.

Global Operations Strategy Options
1. International Strategy2. Multi domestic Strategy3. Global Strategy4. Transnational Strategy
International Strategy
A strategy in which global markets are penetrated using exports and licenses.• Least advantageous with little local
responsiveness & little cost advantage• Little local responsiveness because of exporting
& licensing a good from the home country• Cost advantage may be few because of the
usage of the existing production process at some distance from the new market
• Easiest- as exports can require little change in existing operations, & licensing agreements often leave much of the risk to the licensee
Example: U.S. Steel, Harley- Davidson
Multi domestic Strategy
A strategy in which operating decisions are decentralized to each country to enhance local responsivenessTypically subsidiaries, JV, franchises with substantial independenceAdvantage- maximizing a competitive response for the local marketNo/little cost advantage Many food producers use this strategy to accommodate local taste because global integration of the production process is not criticalConcept- “we are successful in the home market, let’s export the mgt talent & processes, not necessarily the product, to accommodate another market”.Example: Heinz, McDonald's, The Body Shop
Global Strategy
A strategy in which operating decisions are centralized & head quarters coordinates the standardization & learning between facilities, thus generating economies of scaleAppropriate when the strategic focus is cost reduction but has little recommend it when the demand for local responsiveness is highEnd products are similar throughout the worldExample: Texas Instruments, Caterpillar
Transnational Strategy
A strategy that combines the benefits of global scale efficiencies with the benefits of local responsiveness, by recognizing that core competence does not reside in just the “Home” country but can exist anywhere in the organizationDescribes a condition in which material, people & ideas cross /transgress national boundariesThese firms have potential to pursue all 3 operational strategies- Differentiation, low cost, responseKey activities are neither centralized nor decentralized- each subsidiary can carry out its own tasks on a local basisExample: Nestle, Coca - Cola
Global Strategy• Standardized

Process Strategy
It is an organization’s approach to transforming resources into goods & services.The objective of a process strategy is to build a production process that meets customer requirements & product specifications within cost and other managerial constraints.Every good/service is made by using some variation of one of four process strategies:1. Process Focus2. Repetitive Focus3. Product Focus4. Mass Customization
PROCESS FOCUS
• A production facility organized around processes to facilitate low- volume, high variety production.
• The majority of global production is devoted to making low volume , high variety products in places called “job shops”. Such facilities are organized around specific activities / processes.
• Factory, Office, Bakery• Such facilities are process focused in terms of
equipment, layout & supervision• Provide high degree of product flexibility as products
move intermittently b/w processes. Each process is designed to perform a wide variety of activities & handle frequent changes- Intermittent Process
REPETITIVE FOCUS
• Falls b/w the product & the process focus
• Use modules- are parts/ components of a product previously prepared , often in a continuous process
• Repetitive process line is the classic assembly line. Widely used in automobiles & household appliances
Ex: fast food firms
PRODUCT FOCUS
• High volume, low variety processes are product focused. The facilities are organized around products. They are also called continuous processes b’coz they have very long, continuous production runs.
Ex: glass, paper, tin sheets, light bulbs, bolts are made via continuous processSpecialized nature of the facility requires a high fixed cost but low variable costs reward high facility utilization.
MASS CUSTOMIZATION
Rapid, low cost production that caters to constantly changing unique customer desires.It is not just about variety, it is about making precisely what the customer wants when the customer wants it economically.Mass customization brings us the variety of products traditionally provided by low- volume manufacture(process focus) at the cost of standardized high volume(product- focused) production.
PROCESS DESIGN
The transformation process is used to convert inputs into
desired outputs
Types of Process Design
Types of Processes
Continuous Process
Project
Batch Process
Intermittent Process
Job Shop
Semi- Continuous
Process(Repetitive/ Assembly
Continuous Process • Continuous in nature• The set- up time for starting such
processes is usually very long• Once started, they continue for a long
duration• Products produced by such a process are
highly standardized with almost no variety & are measured on a continuous basis rather than in terms of discreet units.
• Ex: Steel, Plastic, Sugar, Textiles, Detergents…
Semi- Continuous Process(Repetitive/ Assembly
• Repetitive in Nature• They produce high volume of output• Products produced have little variety• These processes require highly
specialized machines, semi- skilled workers
• Low cost per unit• Ex: Automobiles, electronic items,
Intermittent Process
• This process is very suitable for a large variety of output, each output taking a different route and hence operations, with different time requirements and sequence.
• Stops at regular interval of time because the product requires processing on a variety of machines.
• The products produced are of different varieties, thus makes the production process slow in comparison to the other processes
The characteristics of intermittent process
1. It is suitable when the output variety is large and the volumes are low.
2. It is flexible in approach since it uses general purpose machines for a variety of outputs.
3. The transformation process is organized around standard operations in the intermittent form ( e.g. in a bank we have saving accounts counter, current account counter, cash counter, advances and time deposits departments etc). Here each functional group is a specialist group.
4. Material handling here depends upon standard operations, and there is a work in process (WIP) inventory.
Types of Intermittent Process
1. Batch Process: adapted when batches or lots of items are to be produced using the same set of machines in the same sequence.Ex: Biscuits to be made in oven…( Salted, Chocolate, batch of bread…)
2. Under the intermittent manufacturing system, the production is done for stock or according to a customer’s order. When the manufacturing is carried on according to the specifications of the customer’s order, it is popularly known as “job lot manufacturing”.
Job Shop handles a larger variety of products than
the batch. The products may be different from
each other that their processing requirements
may be varied processes, on different machines,
different sequences, different processing times.
The items produced may vary in size
Ex: In a restaurant orders given by the
customers……
Job shop results in low volume of output at a given
time & thus costlier.
Project
• Projects are processes that handle very
complex and unique sets of activities which
have to be completed in a limited span of
time.
• Example: R&D projects, Construction of
plants, Building Complexes, implementation
of specialized software in an organization.
Trends in Operations Management
1. Productivity Improvement
2. Global Competition
3. Ethical Workforce Diversity and
Environmental Issues
Theory of Constraints
A Constraint is any factor that limits the
performance of a system and restricts its output.
When constraint exist at any step, capacity can
become imbalanced- too high in some
departments- too low in others.
As a result, the overall performance of the
system suffers.
• The theory was developed 3 decades ago by Eli
Goldratt, a business system analyst.
• The TOC is a systematic management approach
that focuses on actively managing those constraints
that impede a firm’s progress toward its goals of
maximizing profits & effectively using its resources.
• It outlines a deliberate process for identifying &
overcoming constraints.
Toc methods increase the firms’ profits more effectively
by making materials flow rapidly through the entire
system. They help firms to know how process can be
improved to increase overall workflow & how inventory
& work force levels can be reduced while still effectively
utilizing critical resources.
It is important to understand the relevant performance &
capacity measures at the operational level & their
relationship with the financial measures at the firm level.
Capacity Related Terminology
• What is a Constraint?– Any factor that limits system performance
and restricts its output.
• Capacity is the available time for production
• Bottleneck is what happens if capacity is less than demand placed on resource
• Non bottleneck is what happens when capacity is greater than demand placed on resource
• Capacity-constrained resource (CCR) is a resource where the capacity is close to demand placed on the resource
Operational Measures
TOC view Relationship to financial measures
Inventory(I) All the money invested in the system in purchasing things that it intends to sell
A decrease in I leads to an increase in net profit, ROI & cash flow
Throughput(T) Rate at which a system generates money through sales
An increase in T leads to an increase in net profit, ROI & cash flow
Operating Expenses(OE) All the money a system spends to turn inventory into throughput
A decrease in OE leads to an increase in net profit, ROI & cash flow
Utilization(U) The degree to which equipment, space, or workforce is currently being used & is measured as the ratio of average output rate to maximum capacity expressed as a percentage
An increase in U at the bottleneck leads to an increase in net profit, ROI and cash flows
According to the TOC view, every capital
investment in the system, including
machines & WIP materials, represents
inventory because they could all potentially
be sold to make money. Producing a product/
service that does not lead to a sale will not
increase a firm’s throughput, but will
increase its inventory & operating expenses
Kinds of Constraints
• Constraints can occur up or down the supply
chain, with either the firm’s suppliers or customers
or within one of the firm’s processes like
service/product development or order fulfillment.
• Physical –machine, labor, work station capacity,
material shortage, space, quality
• Market- demand is less than capacity
• Managerial- policy metrics, mind set that creates
constraints that impede work flow.
Seven Key Principles of TOC
1. The focus should be on balancing flow, not on balancing capacity
2. Maximizing the output & efficiency of every resource may not maximize the throughput of the entire system
3. An hour lost at a bottleneck or a constrained resource is an hour lost for the whole system. In contrast an hour saved at a non bottleneck resource is a mirage because it does not make the whole system more productive.
4. Inventory is needed only in front of the bottlenecks in order to prevent them from sitting idle, and in front of assembly & shipping points in order to protect customer schedules. Building inventory else where should be avoided.5.Work should be released into the system only as frequently as the bottlenecks need it. Bottleneck flows should be equal to the market demand. Pacing everything to the slowest resource minimizes inventory and operating expenses.
6. Activation of non-bottleneck resources cannot increase throughput, nor promote better performance on financial measures.
7. Every capital investment must be viewed from the perspective of its global impact on overall throughput (T), inventory (I), and operating expense (OE).
Practical application of TOC involves the implementation of following steps:
1. Identify the system bottlenecks
2. Exploit the bottlenecks
3. Subordinate all other decisions to
step2
4. Elevate the bottlenecks
5. Do not let the inertia set in
Bottleneck
• Special type of a constraint that relates to the capacity shortage of a process.
• Defined as any resource whose available capacity limits the organization’s ability to meet the service or product volume, product mix or fluctuating requirements demanded by the market place.
Identification & Management of Bottlenecks
Bottlenecks can be both internal or External to the firm. They Represent a process, a step or a work station with the lowest capacity.Throughput time is the total elapsed time from the start to the finish of a job or a customer being processed at one or more work centers.A workstation in a process is a bottleneck if-a) It has the highest total time/unit processedb) It has the highest average utilization &
workloadc) A reduction of even a single minute in its
processing time would reduce the average throughput time for the entire process.
