Work measurement (objectives): What is the main objective of conducting work measurement studies in manufacturing and services?

Introduction / Context:
Work measurement establishes the time required by a qualified worker to perform a defined task at a specified performance level. Accurate standard times are foundational for planning, costing, and incentives, impacting competitiveness and customer service.

Given Data / Assumptions:

• Defined method (from method study) and stable process conditions.
• Qualified, trained operator working at a standard performance rate.
• Allowances included for fatigue, personal needs, and delays.

Concept / Approach:
Using time study, PMTS (e.g., MTM, MOST), or work sampling, analysts derive standard times. These drive capacity planning, line balancing, MRP scheduling, due-date quoting, labor cost estimates, and incentive plan calibration. Without valid standards, plans are unrealistic, incentives unfair, and quotes inaccurate.

Step-by-Step Solution:

Verification / Alternative check:
Compare scheduled capacity vs. actual throughput; variance reduction after implementing reliable standards validates the objective benefits.

Why Other Options Are Wrong:
Each listed benefit is genuine and complementary; none alone captures the main objective’s breadth. Option (e) is incorrect and contrary to best practice.

Common Pitfalls:
Using outdated standards; neglecting allowances; failing to keep standards synchronized with method changes.

Final Answer:
all of the above
