Some of the most important types of production are:

(i) Job Production

(ii) Batch production and

(iii) Mass or flow production!

A production manager will have to choose most appropriate method for his enterprise. The final decision regarding any particular method of production is very much affected by the nature of the products and the quantity to be produced. Production methods may be broadly classified as Job Production, Batch production and Mass or Flow Production.

Job Production:

Under this method peculiar, special or non-standardized products are produced in accordance with the orders received from the customers. As each product is non- standardized varying in size and nature, it requires separate job for production. The machines and equipment’s are adjusted in such a manner so as to suit the requirements of a particular job.

Job production involves intermittent process as the work is carried as and when the order is received. It consists of bringing together of material, parts and components in order to assemble and commission a single piece of equipment or product.

Ship building, dam construction, bridge building, book printing are some of the examples of job production. Third method of plant layout viz., Stationery Material Layout is suitable for job production.


  1. A large number of general purpose machines are required.
  2. A large number of workers conversant with different jobs will have to be employed.
  3. There can be some variations in production.
  4. Some flexibility in financing is required because of variations in work load.
  5. A large inventory of materials, parts and tools will be required.
  6. The machines and equipment setting will have to be adjusted and re­adjusted to the manufacturing requirements.
  7. The movement of materials through the process is intermittent.


  1. The economies of large scale production may not be attained because production is done in short-runs.
  2. The demand is irregular for some products.
  3. The use of labour and equipment may be an inefficient.
  4. The scientific assessment of costs is difficult.

Batch production:

Batch production pertains to repetitive production. It refers to the production of goods, the quantity of which is known in advance. It is that form of production where identical products are produced in batches on the basis of demand of customers’ or of expected demand for products.

This method is generally similar to job production except the quantity of production. Instead of making one single product as in case of job production, a batch or group of products are produced at one time. It should be remembered here that one batch of products may not resemble with the next batch.

Under batch system of production the work is divided into operations and one operation is done at a time. After completing the work on one operation it is passed on to the second operation and so on till the product is completed. Batch production can be explained with the help of an illustration. An enterprise wants to manufacture 20 electric motors.

The work will be divided into different operations. The first operation on all the motors will be completed in the first batch and then it will pass on to the next operation. The second group of operators will complete the second operation before the next and so on. Under job production the same operators will manufacture full machine and not one operation only.


  1. The work is of repetitive nature.
  2. There is a functional layout of various manufacturing processes.
  3. One operation is carried out on whole batch and then is passed on to the next operation and so on.
  4. Same type of machines is arranged at one place.
  5. It is generally chosen where trade is seasonal or there is a need to produce great variety of goods.

Mass or flow production:

This method involves a continuous production of standardized products on a large scale. Under this method, production remains continuous in anticipation of future demand. Standardization is the basis of mass production. Standardized products are produced under this method by using standardized materials and equipment. There is a continuous or uninterrupted flow of production obtained by arranging the machines in a proper sequence of operations. Process layout is best suited method for mass production units. Flow production is the manufacture of a product by a series of operations, each article going on to a succeeding operation as soon as possible. The manufacturing process is broken into separate operations.

The product completed at one operation is automatically passed on to the next till its completion. There is no time gap between the work done at one process and the starting at the next. The flow of production is continuous and progressive.


  1. The units flow from one operation point to another throughout the whole process.
  2. There will be one type of machine for each process.
  3. The products, tools, materials and methods are standardised.
  4. Production is done in anticipation of demand.
  5. Production volume is usually high.
  6. Machine set ups remain unchanged for a considerable long period.
  7. Any fault in flow of production is immediately corrected otherwise it will stop the whole production process.

Suitability of flow/mass production:

  1. There must be continuity in demand for the product.
  2. The products, materials and equipments must be standardised because the flow of line is inflexible.
  3. The operations should be well defined.
  4. It should be possible to maintain certain quality standards.
  5. It should be possible to find time taken at each operation so that flow of work is standardised.
  6. The process of stages of production should be continuous.

Advantages of mass production:

A properly planned flow production method, results in the following advantages:

  1. The product is standardised and any deviation in quality etc. is detected at the spot.
  2. There will be accuracy in product design and quality.
  3. It will help in reducing direct labour cost.
  4. There will be no need of work-in-progress because products will automatically pass on from operation to operation.
  5. Since flow of work is simplified there will be lesser need for control.
  6. A weakness in any operation comes to the notice immediately.
  7. There may not be any need of keeping work-in-progress, hence storage cost is reduced.
