  • 1.Measuring and Improving Maintenance Performance Salih O. Duffuaa Systems Engineering Department King Fahd University of Petroleum and Minerals

2. Presentation Plan

  • Introduction
  • Evolution of Maintenance Management
  • Why Measure
  • Performance Measurement
    • Structured Auditing
    • Key performance indicator
    • Benchmarking
  • Improvement process
  • Case Studies

3. Role of Maintenance

  • Maintenance is defined as the combination of activities by which equipment, assets or a system is kept or restored to a state in which it can perform its designated function. It is an important factor in product or service quality and can be used as a strategy for successful competition

4. Introduction 5. Maintenance Versus Organization Objectives

  • The objectives and goals of an organization depends on the organization state, strategy and type of business. Some objectives are
    • Meet or exceed customer satisfaction
    • Maximizing profit, Meet set targets
    • Meet set safety standard,
    • Zero product defect
  • Does Maintenance affect these goals ?

6. Evolution of Maintenance Management

  • Prior to 50 th : Necessary evil
  • 50-70 : Preventive maintenance
  • 70 th : Life cycle costing, RCM and Productive maintenance.
  • 80: TPM an RCM
  • 9oth-date: Strategic view of maintenance

7. Why Measure

  • What can be measured will be
  • understood better.
  • What can be measured can be assessed.
  • What can be measured can be managed.
  • What can be measured can be improved.

8. Measuring Maintenance Performance

  • What to measure?
  • How to measure?
  • What to do with measurement output?

9. Continuous Improvement Develop Measurement System(1) Evaluate Maintenance System(2) Identify most deficient areas(3) Identify root causes of deficiencies(4) Develop and implement corrective and preventive actions(5) 10. Measurement System

  • Structured Audit
  • Performance Indicators
  • Benchmarking ( can be utilized by both)

11. Structured Audit Approach

  • What is an audit
  • Standard for the audit ( factors for audit)
  • Organization of the audit
  • Expected out put of the audit

12. Structured Audit

  • The American Heritage Dictionary defines audit as:an examination of records or accounts to check their accuracy.
  • Thomas and Henke (1989), Auditing is a process in which one person verifies the assertions of an other.
  • Carmichael et al (1996), defines audit as : Auditing is an independent investigation of some particular activity.
  • (http://www.columbia)defines an audit as a formal or official examination and verification of the activities of an organizational unit, system, function, or other aspect of the organization's operations. It may include a review of (1) economy and efficiency of operations; (2) effectiveness in achieving program results; and (3) compliance with laws, regulations, and other rules. The audit results in a written report

13. Standard for the Audit

  • Factors/activities to be examined.
  • Standard for each factor.
  • Aggregation of sub-factors and factors.

14. Audit Factors

  • 1. Strategic Management
      • Maintenance mission and objectives
      • Alliance of process with mission andobjectives.
      • Values
      • Performance measurement
      • Effective strategies
      • Strategy assessment

15. Audit Factors

  • 2. Organization and staffing
      • Organization structure
      • Job description
      • responsibilities and supervision
      • Polices and procedures
      • Shops organization
  • 3. Human resources
      • Shop manning
      • Employee motivation

16. Audit Factors

  • 4. Training
      • Management training
      • Planner training
      • Craft training
  • 5. Management control and budget
      • 6.1 Budget planning
      • Reporting and feedback
      • Effective control

17. Audit Factors

  • 6. Work order planning and scheduling
      • Priority system
      • Work order system and procedures
      • Emergency & shutdown scheduling
      • Planning procedures
  • 7. Facilities and resources
  • 8. Stores and material
  • 9. Preventive maintenance and equipmenthistory
  • 1o. Engineering Condition monitoring

18. Audit Factors

  • 11. Information technology
  • 12. Performance analysis and appraisal
  • 13. Safety in maintenance
  • 14. Maintenance and the Environment
  • The audit program we are using has 90 questions distributed over the above 14 main factors.

19. Audit Plan and Execution

  • Examine the audit program to reflect plant special characteristics.
  • Form audit team from consultant in plant personnel.
  • Regular meeting.
  • Corrective and preventive actions.

  • Factor 2: Organization and Staffing
    • Document procedures for PM
    • Supervisor technician ratio
    • Establish a suitable planner-worker ratio.
    • Decentralize some of the maintenance activities.
  • Factor 13:Safety in maintenance
    • Include safety within maintenance process
    • Enforce safety rules
    • Training program for maintenance personnel.

25. Performance Measures

  • An alternative or integrated approach with structured auditing ?
  • It links processes to objectives.

26. Performance Measures

  • There are literally hundreds of potential indicators
  • Appropriate indicators depend on many factors, such as
    • Level in the organization to use the information
    • Existing data collection systems, and how easily modified
    • Staff availability to develop/maintain systems
    • Demands of managers &teams for the information, and their level of sophistication (foreman vs. MBA)
  • Frequency of reporting also is situation dependent
  • Stratification options by plant, department, machine, product line, etc., are important

27. Managerial Classification

  • Macro Indicator
    • Macro-indicators(for upper management, primarily)
  • Micro Indicator
    • Micro-indicators(for lower levels of management)

28. Macro Indicator

  • maintenance expense dollars as a percent of replacement asset value.
  • maintenance expense dollars per unit produced
  • maintenance expense dollars as a percent of plant controllable expenses
  • regulatory compliance indicators
  • Productive capacity

29. Micro-Indicator

  • maintenance budget compliance (budget vs. expense)
  • monthly expense dollars (by equipment type)
  • percent overtime (3-9% sometimes cited as ideal)
  • percent emergency work

30. System Classification

  • Input Measures Primarily Cost Measures
  • Output measures
  • Within The System Measures

31. Input Measures

  • Input Measures are Mostly Related To Cost
  • Labor : Cost of trades, semi-skilled etc
  • Mate
