Step 1: Understanding the Concept:
In Functional Foremanship, Taylor advocated for separating planning functions from doing (execution) functions. He believed workers should not be burdened with the mental task of planning while doing physical labor.
Step 2: Detailed Explanation:
1. Planning Work: Requires mental qualities such as intelligence, education, special knowledge, and analytical skills. Thus, people with technical mastery and grit are assigned here (under the Planning Incharge).
2. Execution Work: Requires physical attributes like energy, health, and speed to carry out the physical operations on the shop floor. Thus, people with energy and good health are assigned here (under the Production Incharge).
Step 3: Final Answer:
Technical mastery is for Planning; Energy/Health is for Execution. This matches option (A).
