### Pqm bottlenecks

1. 1. WHAT IS A BOTTLENECK? Performance an entire system is limited by a single or limited number of components. The term is taken from its literal meaning. Fundamental intuition about bottlenecks carried over from the days of Henry Ford. Video
2. 2. TYPES OF BOTTLENECKS Process Bottleneck Activity Process Bottleneck Time
3. 3. TYPES OF BOTTLENECKS Functional Bottleneck Process 1 Process 1 continues Process 2 Process 2 continues Functional Bottleneck Process 3 Process 3 continues
4. 4. MANUFACTURING BOTTLENECKS It is a stage in a process that causes the entire process to slow down. Restricts the output of production facilities. Before After
5. 5. CAUSES OF MANUFACTURING BOTTLENECKS PHYSICAL HUMAN •Equipment breakdown •Inherent equipment capacity limitations •Poor training and skill levels •Technical support problems •Inappropriate scheduling LATENT
6. 6. MANAGING BOTTLENECK In 1984 Dr. Eliyahu M. Goldratt introduced the Theory of Constraints in his book the Goal. The Five Focusing Steps : Identify the process' constraints Decide how best to exploit the process constraints Subordinate everything else to the above decisions Evaluate the process constraint Remove the constraint and re-evaluate the process
7. 7. MANAGING BOTTLENECK 5 Focusing Steps : Identify the Bottleneck  Finding Largest WIP Inventory. Exploit the Bottleneck  Optimize bottleneck machine speed.  Give maintenance high priority.
8. 8. MANAGING BOTTLENECK Subordinate Other Tasks  Letting the non-bottlenecks help the bottleneck  Everybody works at the pace of the bottleneck Elevate the Bottleneck  Adding more people or machines  Training and mentoring more operators for the bottleneck Re-evaluate the process  New Bottleneck Emerges  Repeat the Steps and continue improving the system.
9. 9. BOTTLENECKS IN SUPPLY CHAIN
10. 10. BOTTLENECKS IN COMPUTERS A point in the enterprise where the flow of data is stopped entirely In the user network where there is excessive contention for internal server resources Hardware failures
11. 11. BOTTLENECKS IN CORPORATE SECTOR Communication gap Bottleneck as a bottleneck in HR Bottleneck in the process
12. 12. POPULATION BOTTLENECKS It is an event that drastically reduces the size of a population. It produces a decrease in the gene pool of the population. Production bottleneck may be caused by various events. Original Bottleneck Population -ing Event Surviving Population
