Show Answers:

  1. Constraint?
    • Anything that limits the performance of a system relative to its goal
    • constraints can be physical or policy
  2. the chain analogy
    • the contribution of a link a link is strongly dependent upon the performance of the other links
    • the chain is oonly as strong as its weakest link
  3. What is theory of Constraints
    A systems based directed process of ongoing improvement
  4. what is meant by systems based ?
    an integrative or holistic approach to identifying organization problems and the development and implementation of possible solutions
  5. fundamental Theory of Constraints Principles
    • -system thinking is better for solving problems
    • -there is no such thing as optimal solitons
    • -Assume all things are not of equal importance
  6. Chupchiks
    Those things which we commonly work on that provide limited or no benefit relative to our goal
  7. how TOC focuses the process of ongoing improvement for physical constraints
    • 1. define the goal
    • 2. determine the system measurements
    • 3. Five steps of focusing
  8. the goal ?
    What the system strives to achieve. The primary focus and objective of the system
  9. Necessary Conditions?
    That which must be satisfied prior to achieving the goal (ex. prerequisite)
  10. Performance Measurements
    Operating Expense
    throughput- the rat at which the system generates money through sales

    • Inventory-all the money the system invests in purchasing things the system intends to sell
    • Operating Expense- all the money the system spends turning inventory into throughput
  11. The Five Steps of Focusing
    • 1. Identify the systems constraints
    • 2.Decided how to exploit the systems constraints
    • 3.Subordinate everything else to the above decision
    • 4.Elevate the systems constaints
    • 5.If in the previous steps a constraint has been broken, go back to step 1
    • warning dont let inertia to become a constraint
  12. Five steps of Focusing ( Drum-Buffer- Rope)
    • Drum-the most constraining element in a process which should be used to pace the entire system(identify)
    • Buffer- a protective cushion in the form of inventory or timing to protect the planned flow against statistical fluctuationĀ  (Exploit)
    • Rope-backwards scheduling( offset lead time) of material released into the system on the basis of the constraint usage (Subordinate)
  13. Activation is not equal to utilization
    activation is not equal to utilization
  14. Paradigms
    • is a set of rules or regulations that do two thingsĀ 
    • 1. establish or define boundaries
    • 2. it tells you how to behave inside the boundaries
    • EX. Morning reteen
  15. Paradigm paralysis
    • terminal disease of certainty
    • everyone has paradigm paralysis
  16. creators of the new paradigms tend to be ____
  17. Switching to a new paradigms takes ______
  18. ______ type of thinking is a Paradigm
  19. systems
    a set of interrelated parts that must work together
  20. what paradigms do you feel are challenged in the goal
    that a busy employee is a productive employee
  21. ______ is a sign of not being efficient
  22. a company that is working at 100 % efficiency is heading into bankruptcy
  23. A bottleneck is a constraint, but a constraint is not always a bottleneck
  24. system thinking is better for solving problems (look at the bigger picture)
  25. there is no such thing as the perfect (optimal) solution
  26. improvement
    where you are at and where you want to go and measurements
  27. chupchiks
    • unimportant
    • ex Pissing in the wind
