OCSM exam 2 | UPDATED Questions with 100% Verified
Answers
Q1: Work Measurement Techniques
A: Methods used to determine time required to perform a task
Q2: Standard Elemental Times
A: Uses historical time data for repetitive tasks
Q3: Predetermined Time Standards (PTS)
A: Uses motion/time systems without direct observation
Q4: Work Sampling
A: Random observations used to estimate time spent on activities
Q5: Stopwatch Time Study
A: Direct timing of a task using a stopwatch
Q6: Work Sampling Formula
A: n = (z/e)² × p■ (1 − p■ )
Q7: Work Sampling Advantage
A: Low cost, minimal disruption
Q8: Work Sampling Disadvantage
A: Less precise, requires many observations
Q9: Observed Time (OT)
A: Average time of observations (sum of times ÷ number of observations)
Q10: Normal Time (NT)
A: OT × Performance Rating
Q11: Standard Time (ST)
A: NT × Allowance Factor
Q12: Performance Rating (PR)
A: Adjustment factor based on worker speed vs standard
, Q13: Allowance Factor (AF)
A: Accounts for breaks, fatigue, delays
Q14: AF (job)
A: 1 + A
Q15: AF (day)
A: 1 / (1 − A)
Q16: Work Sampling vs Stopwatch Study
A: Sampling = cheaper, less precise; Stopwatch = more accurate, more costly
Q17: Forward Scheduling
A: Start jobs as soon as possible
Q18: Backward Scheduling
A: Start from due date and work backward
Q19: Infinite Loading
A: Assigns work without considering capacity
Q20: Finite Loading
A: Assigns work based on actual capacity limits
Q21: FCFS Rule
A: Jobs processed in order they arrive
Q22: SPT Rule
A: Shortest processing time first
Q23: EDD Rule
A: Earliest due date first
Q24: Critical Ratio (CR)
A: Time remaining ÷ processing time
Q25: CR < 1
A: Job is behind schedule
