   aWhat are the objectives of work measurement in an industry?
   How to answer

   • Definition of work measurement
   • Objectives - setting standards, costing, incentives, planning
   • Importance for productivity and labour control
6. 7 Marks
   bWhat are objectives of Time Study.
   How to answer

   • Definition of time study
   • Objectives - determine standard time, efficiency, wage fixation
   • Use in method improvement and production planning
7. 14 Marks
   A work sampling study showed that 25% of a work week of 48 hours was consumed by avoidable delays. If each time a work sampling observation was made the operator was rated and the average of such rating was 110%. If 80 units were produced by the operator in that period. Calculate standard time.
   How to answer

   • Calculate effective working time excluding 25% avoidable delays from 48 hours
   • Apply performance rating 110% to get normal time
   • Divide normal time by 80 units to get time per unit
   • Add allowances if applicable to get standard time
8. 7 Marks
   aWhat do you understand by Standard data? What are its advantages?
   How to answer

   • Definition of standard data for time study
   • How standard data is compiled from past studies
   • Advantages - quick estimation, consistency, cost saving
   • Applications in planning and costing
9. 7 Marks
   bGive the list of various advantages of using "Predetermined Motion Time Standards".
   How to answer

   • Meaning of Predetermined Motion Time Standards (PMTS) e.g. MTM, MOST
   • Advantages - no stopwatch, pre-planning, consistency
   • Cost, time and labour relations benefits
   • List of 5-6 distinct advantages
10. 7 Marks
    aHow will you integrate 'operation and operator'?
    How to answer

    • Meaning of operation and operator integration
    • Man-machine chart / activity chart approach
