Which of the following is the most appropriate example of standardization in the manufacturing industry?

a)Workload is balanced, and the types and volume of components taken in from the previous process are equalized.b)In order to rationalize production activities, the components and procedures that are required for manufacturing are unified.c)In order to improve the execution speed of a production management program, the optimum algorithm is selected.d)Production planning, production processes, and working methods are simplified through a reduction in product types and a review of work details.

Explanation

Unifying the components and procedures required for manufacturing — standardization sets common specifications and methods so that production can be rationalized.

In manufacturing, standardization means deciding one set of parts, dimensions, materials and work procedures and using it throughout. Common parts are interchangeable and can be bought in volume, fixed procedures give stable quality, and training becomes easier. It is one of the three S of rationalizing production: simplification, standardization and specialization.

Answer (b)

Why not others:

•(a) — balancing the workload and evening out the types and volume of parts taken from the previous process is production levelling (heijunka) in the Toyota production system
•(c) — choosing the best algorithm to speed up a production management program is performance tuning of software, not standardization of manufacturing
•(d) — reducing the number of product types and reviewing work details to make planning, processes and methods simpler is simplification, another of the three S

Key rule: Of the three S of rationalization, simplification cuts variety, standardization unifies parts and procedures, and specialization concentrates on particular products or tasks.
