- 4. Do we really want or need another New Theory? 23rd September, 2008 “ The significant problems we face today can not be resolved at the same level of thinking we were at when we created them.” - Albert Einstein

- 16. Theory of Constraints is about Management 23rd September, 2008
- 17. <ul><li>The three important questions for a manager </li></ul><ul><ul><li>What is the Ultimate goal? </li></ul></ul><ul><ul><li>Where does he or she stand in relation to the goal? </li></ul></ul><ul><ul><li>The magnitude and direction of the change needed to move from the status quo to where he or she wants to be (the goal). </li></ul></ul>23rd September, 2008 Theory of Constraints is about Management
- 18. <ul><ul><li>“ Average managers are concerned with methods, opinions, and precedents. Good Managers are concerned with solving problems ” </li></ul></ul><ul><ul><li>- William Dettmer </li></ul></ul>23rd September, 2008

- 21. Concept of System Constraints 23rd September, 2008 What keeps your system from doing better? Is there something that is constraining your system from reaching its GOAL?
- 22. Systems as Chains <ul><ul><li>Assume the SYSTEM to be a chain with ‘n’ links and with a goal of transmitting force from end A to B . </li></ul></ul>23rd September, 2008 A B 1 2 3 6 5 7 4

- 33. Basic Questions for Managers <ul><li>What’s the desired standard of performance (System’s Goal ) </li></ul><ul><li>What to change? (Where is the constraint?) </li></ul><ul><li>What to change to? (What should we do with the constraint?) </li></ul><ul><li>How to cause the change? ( How do we implement the change?) </li></ul>23rd September, 2008 Note: These are system-level questions, not process-level

- 56. Theory of Constraints ……a summary <ul><li>Understanding of the system is mandatory to improving it </li></ul><ul><li>Any system has a Goal </li></ul><ul><li>The Leader is responsible for the Goal </li></ul><ul><li>Theory of Constraints is about Leadership and Management </li></ul><ul><li>Every System has one and only one constraint at any instance of time </li></ul><ul><li>If you don’t impact the constraint then there is no effect on the system’s improvement </li></ul><ul><li>Improvement is a long term and continuous process </li></ul>…… Goldratt has used business novels to get his concepts across which can be grasped by people like us and practiced… 23rd September, 2008
