解説
問 5
Incorrectア
Balancing the workload and “leveling” the types and quantities of parts is leveling (the idea behind the kanban system and just-in-time), which smooths out production volume and timing; it is a different concept from standardization, which unifies parts and procedures.
- イ
正解 Standardization means unifying and making common such things as products, parts, procedures, and methods, so as to rationalize and streamline production activities. Choice イ says “unified the parts and procedures required for manufacturing in order to rationalize production activities”, which describes the very essence of standardization, namely “unification”; therefore it is the most appropriate example of standardization. Standardization leads to securing interchangeability, stabilizing quality, and reducing costs.
Incorrectウ
Selecting the optimal algorithm to improve a program's execution speed is a matter of software performance improvement and algorithm design; it has nothing to do with standardization, which unifies manufacturing parts and procedures.
Incorrectエ
Reducing the variety of products and reviewing the work content to “simplify” the production plan, processes, and methods is simplification, which is distinguished from standardization whose aim is unification (it is a separate element within the 3S: simplification, standardization, and specialization).
ここがポイント
- Standardization is the activity of unifying and making common such things as parts, procedures, and methods to rationalize production; it leads to securing interchangeability, stabilizing quality, and reducing costs.
- Distinguish among the 3S of production rationalization (simplification, standardization, specialization) and leveling: “unification” means standardization, “reducing variety and simplifying” means simplification, and “smoothing production volume” means leveling.
