Shortening means:

15. We need a KISS (Keep It Small and Simple)

16. Now we are talking:
individual lead times in iteration 5 average lead times per iteration*
20 8
lead time in days
15 6
lead time in days
10 4
5 2
0 1
5 6 7 8 9 10 2 3 0
1 2 3 4 4 5
work items, # iterations
*an iteration is 5 days long

we changed here

25. One more example, just for fun :-)
‘M’ sized items on weekdays
number of items average lead time

Monday Wednesday Friday Monday Wednesday Friday
26. We don’t use it, but worth mentioning:
work in progress *
cycle time =
(lead time) capacity (throughput)
Our “ideal” WIP Limit would be: 8 * 1 = 8
* Little’s Law
