An operation in a television factory has an average observed time of 6 minutes. The performance rating of the worker timed was estimated at 90%. Practice in this department is to allow 8% for the constant allowances. Currently, there is no variable allowance.
a. Find the normal time for the operation.
b. Compute the standard time for the operation.
c. Recompute the standard time if a variable allowance of 8% is factored in.

Constant Allowances

Fixed sums or quantities that are allocated regularly, such as allowances in budgets or time estimations in project management.

Performance Rating

A quantitative assessment often used to evaluate the efficiency, output, or success of an individual, system, or organization in achieving its objectives.

Normal Time
