  • There are two different types of bottlenecks: - Capacity contraint resource - a resource limited by capacity, like a bottle - non instantly available resource - a resource that is not available all the time

    1. 1. What can traffic inteach you about yourdevelopment process<br />Håkan Forss - hakan.forss@avegagroup.se - @hakanforss<br />
    2. 2.
    3. 3. Little’s Law<br />Work-in-Process<br />Throughput<br />Cycle Time =<br />
    4. 4.
    5. 5.
    6. 6. 8 cars / min<br />4 cars / min<br />With less work-in-progress<br />Shorter cycle time<br />Or<br />Higher throughput<br />

    10. 10. TheoryofConstraints<br />
    11. 11.
    12. 12.
    13. 13. 5<br />
    14. 14. Don’t allow inertia to cause a system constraint.<br />
    15. 15.
    16. 16. Capacity = 4<br />Capacity = 6<br />Capacity = 6<br />Throughput = 4<br />You can never go faster than your bottleneck<br />No need for higher capacity after the bottleneck than at the bottleneck<br />Higher capacity in front of the bottleneck will lower total throughput<br />

    23. 23. Non-instantavailabilityresource<br />A resource that is not available all the time<br />
    24. 24. Non-instantavailabilityresource & bottleneck<br />

    27. 27.
    28. 28.
    29. 29. You can never go faster than your bottleneck<br />Balance demand against throughput to keep work-in-progress low<br />Low work-in-progress<br />Keeps cycle time down <br />Makes bottlenecks visible faster<br />
    30. 30.
    31. 31. Slow down to go faster <br />Slowing down can stabilize the process flow<br />A stable process can go faster<br />
