The major steps involved are:

Step No 1:
The product designer and the process engineers need to work in close cooperation during the design of the part to ensure that all possible manufacturing problems are taken into consideration as the component part design is developed. This will also ensure economic manufacture of the component parts and for the product as a whole. Besides, the design changes that may be required at a later date to accommodate manufacturing processes, will also be minimum.

Step No 2:
Determination of the three basic factors of volume, quality and the availability of manufacturing equipment is possible once the design of the component part is completed. Purchase or development of new or more modern equipments may be considered.

Step No 3:
The next step is the decision to ‘make’ or ‘buy’. Comparison of the purchase price for a component part, with the estimated manufacturing cost, as determined by the process engineer, enables the decision maker to decide, whether to make or buy the component part. Other factors such as, maintenance of employment levels, optimum utilization of plant facilities and relationship with vendors, also enter into the considerations.

Step No 4:
Assuming that the decision is taken to make the part in-house, the next step is to consider all the work that is necessary to bring the part from the raw material stage to the completely processed part stage, which is ready for assembly.

Step No 5:
Determination of the various operations to be carried out and their sequences is the next step. The basic factors of volume to be produced, the required quantity off the product and the capabilities of the equipment available are carefully considered in this step. Each operation is assigned to the type and size of the machine or work station that will perform the job, most economically.

Step No 6:
The last step in operation analysis is to arrange the operations in proper sequence for the most economical manufacture.
