MMPC 009 Solved Guess Paper 2026 for Management of Machines and Materials (IGNOU Management Programme)

Manufacturing versus Service Organisations

Question: What are the major distinctions between a manufacturing enterprise and a service organisation? Discuss with suitable examples. Why is it more difficult to increase productivity of a service system as compared to a production system?

Meaning of Operations Management

Operations Management may be defined as the design, operation and improvement of the production systems that creates the firm's primary products or services. The concept of production is generalised as the process through which goods and services are created, bringing together people, machines and materials to satisfy human wants.

Major distinctions

The textbook, drawing on Richard B. Chase, lists seven differences. Tangibility: goods are physical outputs such as an automobile or furniture, while services are intangible psychological benefits, and services are non-inventoriable because no closing stock can be accumulated. Customer participation: in service the customer often participates in production, whereas manufacturing has little customer contact during production.

Heterogeneity: no two services are exactly alike, and a dentist treating two patients with identical ailments may render similar service yet the patients perceive different quality. Simultaneous production and consumption: service happens in the customer's presence, while manufactured goods are produced first and distributed later. Labour intensive nature: a typist's labour on one foolscap page may cost ₹20 while the paper is ₹0.20.

Market reach: manufactured products with automation can serve national markets, while services cannot be shipped and shrink to local markets. Irreversibility: a bad haircut cannot be undone, whereas a defective pen can be returned or replaced.

Why service productivity is harder to raise

Productivity is the output input ratio, P = O / I. Output is intangible, so services cannot be counted, stocked or weighed and gains are difficult to quantify. Demand varies hourly or daily, making capacity planning and standardisation harder. The customer sets the pace, so the provider cannot speed up unilaterally. Labour content is high, and heterogeneity means efficiency gains can easily reduce perceived quality.

Batch Production against Mass Production

Question: Define batch production. Distinguish it from mass production. Under what conditions is batch production justified? Discuss the advantages and disadvantages of batch production.

Meaning of batch production

In batch production a continuous demand for certain products exists, but because the rate of production exceeds the rate of demand, there is a need to produce products in batches. The scheduling problem here is concerned with determining the batch sizes for products and the order in which they should be produced.

Batch production is resorted to when a variety of products is to be made and volumes are not large enough to justify a separate line for each product. General purpose machines are used, material flow is more complex than in mass production, and a process layout is normally employed with similar machines grouped into departments while different jobs follow their own routes.

When batch production is justified

It applies when the rate of production exceeds the rate of demand for any single product, when several products share common general purpose facilities, when variety and flexibility matter more than speed, and when demand exists continuously for each product but not at volumes warranting a dedicated line.

Advantages

The textbook lists five: better machine utilisation so fewer machines are required, high flexibility in equipment and manpower allocation, low investment in machines, greater job satisfaction owing to the diversity of jobs, and the possibility of specialised supervision.

Disadvantages

Six are identified: expensive material handling from longer and irregular flow lines, involved planning and control, longer total production time, large in process inventory, space and capital tied up by work in process, and the need for higher grades of skill.

Value Engineering as a Human Relations Programme

Question: Explain the meaning and process of Value Engineering. Trace its historical perspective. Critically examine the statement: "Value Engineering is more of a human relations, team building and motivation programme than anything else."

Meaning

Value Engineering is an organised creative approach which has for its purpose the efficient identification of unnecessary cost, that is, cost which provides neither quality, nor use, nor life, nor appearance, nor customer features. The basic objective is equivalent or better performance at lower cost while maintaining functional and quality requirements.

Historical perspective

Value Engineering originated at the General Electric Company during the Second World War, when many materials were in short supply. L. D. Miles, associated with a committee to identify substitute materials, organised a formal team oriented methodology called Value Analysis.

Miles wrote his book in 1961 and is recognised as the father of Value Engineering. The first formal programme was set up by the Navy Bureau of Ships in 1954, and the Society of American Value Engineers followed in 1959. In India, the Indian Value Engineering Society promotes awareness of the discipline.

The Job Plan

The Mudge Job Plan has seven phases: General, Information, Function, Creation, Evaluation, Investigation and Recommendation.

Examining the statement

The statement is largely justified. The General Phase is the foundation of the entire Job Plan and its five techniques are predominantly behavioural: use good human relations so that assistance replaces resistance, inspire teamwork by subordinating personal prominence to the group, work on specifics rather than generalities, overcome roadblocks by recognising killer phrases that resist change, and apply good business judgment based on facts rather than feelings.

However, the statement cannot be accepted without qualification. Behavioural technique alone produces goodwill, not savings. It must be paired with rigorous functional analysis, since Value Engineering is function oriented while conventional cost reduction is item oriented, and it does not compromise quality whereas ad hoc cost cutting tends to.

Job Design and Its Historical View

Question: Define job design. How has management viewed job design since the Industrial Revolution? List the important factors that must be addressed in job design and discuss the various technological factors for an effective job design.

Meaning

Job Design is the consciously planned structuring of work effort performed by an individual or a team of persons. It is a function of specifying the work activities of an individual or group in an organisation to develop job structures meeting the need of the organisation and satisfying the job holder's personal requirements.

Historical view

Three broad phases are traced. In the pre industrial era, work was done by craftspersons using ingenuity and long experience rather than systematic study, and skill saving devices came from flashes of genius.

After the First World War, in the mass production era, the scientific method of work design achieved its greatest success on assembly lines, and man was viewed as an extension of the machine within a costly equipment dominated system.

In the modern era, industrial engineers initially applied a machine theory of man. Social scientists then redirected attention to behavioural aspects, giving us ergonomics, work physiology, job enlargement, job enrichment, job rotation and socio technical systems.

Four groups of factors

Design or technological factors covering equipment layout, seating, displays and controls; environmental factors covering lighting, ventilation, temperature, humidity and noise; organisational factors covering specialisation, work rules, supervision and structure; and behavioural factors covering motivation, satisfaction, enrichment, enlargement and rotation.

Technological factors in detail

Equipment design should start with the operator, laying out areas for vision, controls, sitting and leg room using anthropometric data. Operators leaving their work places frequently for a posture change is a sign of poor seating.

Standard measurements of men and women must be referenced, because many machines remain inconvenient having never been redesigned for human reach. Good seating elements include the length, width and shape of the seat, the shape and height of the backrest, height above floor and footrest design, with a flat surface preferred over a bar.

Classification and Codification of Materials

Question: Define classification of materials. Explain the classification of materials on the basis of nature. What is codification? Discuss the various objectives of a codification system and outline its essential features.

Meaning of classification

Classification is defined as the process of arranging things in groups or classes according to their resemblances and affinities, and gives expression to the unity of attributes that may subsist among a diversity of individuals. Its major purposes are to devise common planning and control procedures, common purchase, inspection, storing and issuing procedures, and common accounting and evaluation procedures.

Classification by nature

Ten categories are given: raw materials such as cotton and yarn; machinery and equipment including presses, lathes and motors; consumable items such as coal, oils and lubricants; chemicals such as acids, salts and carbide; inflammable items such as petrol and kerosene stored away from the main building; fuel stock used in furnaces and ovens; furniture; scrap materials; packaging materials; and general items such as cleaning materials and uniforms.

Meaning of codification

Codification is a process of representing each item by a group of numbers and alphabets indicating the group, the subgroup, the type and the dimensions of the item. Codes typically run to 8 or 13 digits. In the illustrated 13 digit code, digits 1 to 2 give the major group, 3 to 4 the subgroup, 5 to 7 dimensional characteristics, 8 minor variations, 9 location of storage, 10 to 11 the user department, 12 the product line and 13 other information.

Seven objectives

Accurate and logical identification, prevention of duplication, standardisation and variety reduction, efficient purchasing, efficient recording and accounting, easy locating, indexing and inspection, and easy computerisation.

Eight essential features

Brevity, logical structure, flexibility, uniqueness, easy understandability, proper choice of coding symbols avoiding confusable characters such as O and 0 or Z and 2, equal length layout, and adequate capacity given by C = S to the power p.
