    PowerPoint presentation to accompany Heizer and Render Operations Management, 10e Principles of Operations Management, 8e PowerPoint slides by Jeff Heyl
  2. Outline Human Resource Strategy for Competitive Advantage Labor Planning Work Schedules Job Classifications and Work Rules Job Design Labor Specialization Job Expansion Motivation and Incentive Systems Ergonomics and the Work Environment The Visual Workplace Labor Standards Historical Experience Time Studies Ethics
  3. Learning Objectives Describe labor planning issues Identify the major issues in job design Identify major ergonomic and work environment issues Establish labor standards Compute the normal and standard times in a time study
  4. Rusty Wallace’s NASCAR Racing Team High performance pit crews are a key element of a successful race team and pit crew members can earn $100,000 per year – for changing tires! Each position has very specific work standards Pit crews are highly organized and go though rigorous physical training Pit stops are videotaped to look for improvements
  5. Rusty Wallace’s NASCAR Racing Team
  6. Human Resource Strategy The objective of a human resource strategy is to manage labor and design jobs so people are effectively and efficiently utilized People should be effectively utilized within the constraints of other operations management decisions People should have a reasonable quality of work life in an atmosphere of mutual commitment and trust
  7. Labor Planning Employment Stability Policies Follow demand exactly Matches direct labor costs to production Labor is treated as a variable cost Hold employment constant Maintains trained workforce Labor is treated as a fixed cost
  8. The Workplace Work Schedules Standard work schedule Flex-time Flexible work week Part-time Job Classification and Work Rules Specify who can do what Specify when they can do it Often result of union contracts Restricts flexibility and consequently efficiency of production
  9. Job Design: Labor Specialization The division of labor into unique tasks First suggested by Adam Smith in 1776 Development of dexterity Less loss of time Development of specialized tools Later Charles Babbage (1832) added another consideration Wages exactly fit the required skill required
  10. Job Design: Job Expansion Adding more variety to jobs Intended to reduce boredom associated with labor specialization Job enlargement Job rotation Job enrichment Employee empowerment
  11. Enriched job Planning (Participate in a cross-function quality improvement team) Enlarged job Task #3 (Lock printed circuit board into fixture for next operation) Present job (Manually insert and solder six resistors) Task #2 (Adhere labels to printed circuit board) Control (Test circuits after assembly) Job Enlargement Figure 10.2
  12. Core Job Characteristics Jobs should include the following characteristics Skill variety Job identity Job significance Autonomy Feedback
  13. Self-directed teams Empowerment Self-direction Enrichment Enlargement Specialization Job expansion Job Design Continuum Figure 10.3
  14. Motivation and Incentive Systems Bonuses Profit-sharing Gain sharing Incentive plans Knowledge-based systems
  15. Ergonomics and the Work Environment Ergonomics is the study of the interface between man and machine Often called human factors Operator input to machines
  16. Ergonomics and Work Methods Feedback to operators The work environment Illumination Noise Temperature Humidity
  17. The Visual Workplace Use low-cost visual devices to share information quickly and accurately Displays and graphs replace printouts and paperwork Able to provide timely information in a dynamic environment System should focus on improvement
  18. The Visual Workplace Visual utensil holder encourages housekeeping A “3-minute service” clock reminds employees of the goal Figure 10.8
  19. Reorder point Line/machine stoppage Parts/ maintenance needed All systems go Part A Part B Part C Andon The Visual Workplace Visual signals at the machine notify support personnel Visual kanbans reduce inventory and foster JIT Figure 10.8
  20. The Visual Workplace Quantities in bins indicate ongoing daily requirements and clipboards provide information on schedule changes Process specifications and operating procedures are posted in each work area Figure 10.8
  21. Labor Standards Manpower planning depends on a knowledge of the labor required Labor standards are the amount of time required to perform a job Labor standards determine labor requirements, costs, and fair work Necessary for determining staffing requirements Important to labor incentive systems
  22. Time Studies Involves timing a sample of a worker’s performance and using it to set a standard Requires trained and experienced observers Cannot be set before the work is performed
  23. Time Studies - Compute average observed time: - Determine performance rating and normal time: - Sum normal times of elements to find task normal time - Compute the standard time
  24. Rest Allowances Personal time allowance 4% - 7% of total time for use of restroom, water fountain, etc. Delay allowance Based upon actual delays that occur Fatigue allowance Based on our knowledge of human energy expenditure
  25. Normal time = (Average observed time) x (Rating factor) = (4.0)(.85) = 3.4 minutes Normal time 1 - Allowance factor Standard time = = = 3.4 1 - .13 3.4 .87 = 3.9 minutes Time Study Example 1 Average observed time = 4.0 minutes Worker rating = 85% Allowance factor = 13%
  26. Cycle Observed (in minutes) Performance Job Element 1 2 3 4 5 Rating Compose and type letter 8 10 9 21* 11 120% Type envelope address 2 3 2 1 3 105% Stuff, stamp, seal, and 2 1 5* 2 1 110% sort envelopes Time Study Example 2 Allowance factor = 15% Delete unusual or nonrecurring observations (marked with *) Compute average times for each element Average time for A = (8 + 10 + 9 + 11)/4 = 9.5 minutes Average time for B = (2 + 3 + 2 + 1 + 3)/5 = 2.2 minutes Average time for C = (2 + 1 + 2 + 1)/4 = 1.5 minutes
  27. Time Study Example 2 Compute the normal time for each element Normal time = (Average observed time) x (Rating) Normal time for A = (9.5)(1.2) = 11.4 minutes Normal time for B = (2.2)(1.05) = 2.31 minutes Normal time for C = (1.5)(1.10) = 1.65 minutes Add the normal times to find the total normal time Total normal time = 11.40 + 2.31 + 1.65 = 15.36 minutes
  28. Standard time = = = 18.07 minutes Total normal time 1 - Allowance factor 15.36 1 - .15 Time Study Example 2 Compute the standard time for the job
  29. Ethics and the Work Environment Fairness, equity, and ethics are important constraints of job design Important issues may relate to equal opportunity, equal pay for equal work, and safe working conditions Helpful to work with government agencies, trade unions, insurers, and employees
  30. In-Class Problems from the Lecture Guide Practice Problems Problem 2: Develop an Activity Chart for doing three loads of laundry.
  31. In-Class Problems from the Lecture Guide Practice Problems Problem 3: Carolyn Barrett, a marketing surveyor, takes an average of 10 minutes to complete a particular questionnaire. Carolyn’s performance rating (pace) is 110% and there is an allowance of 15%. What is the Normal time for completing this questionnaire? What is the Standard time for completing this questionnaire?
  32. In-Class Problems from the Lecture Guide Practice Problems Problem 5: The two steps in preparing chocolate candy bars are molding and packaging. Personal fatigue and delay allowances are set at 15%. The molding machine operator is rated at 110% and the packer is rated at 80%. Observed times per batch are given below. Determine the Normal and standard times for both tasks.
