Assignment:
Susan Cottenden clocked the observed time for welding a part onto truck doors at 5.3 minutes. The performance rating of the worker timed was estimated at 105%. Find the normal time for this operation.
Note: According to the local union contract, each welder is allowed 3 minutes of personal time per hour and 2 minutes of fatigue time per hour. Further, there should be an average delay allowance of 1 minute per hour. Compute the allowance factor and then find the standard time for the welding activity.
Provide complete and step by step solution for the question and show calculations and use formulas.
