After getting a good response to the sprint duration poll, I thought it would be interesting to ask the question at a somewhat higher level. How long does it take your company to deliver business value?
Well the poll is closed and the results are in. And the results are a bit, well, puzzling.
% with equal or better cycle time
< 1 Month
So I published it on the Xing Agile Methods forum and the Xing Forum English Project Management Lounge and got some more responses. All in all, 35 votes: 77% claimed 3 months or less, 23% reported 8 months or more. A very small sample, but perhaps some interesting trends can be found in the data...
First of all, I think there are more results from agile companies than non agile companes, so while the proportions within the groups (<5>=8 Months) may well be OK, I do believe the slow group is in reality the larger group. But how to prove this? And why the low reponse rate?
Could it be that most people don't understand the relationship between speed and success in the market? Next time I will be sure to add the responses "Don't know" and "Don't care" (perhaps, "not an issue" would be a bit less provocative).
Or perhaps is this is an issue which companies focussed on agile are aware of, but people from waterfall companies really don't know -- or maybe just don't want to admit -- how big the difference is between themselves and their more agile competitors...
Here are some Lean questions for you: if your company cycle time is high (say a year or more), what would it mean to reduce the cycle time by a factor of two? Say from two years down to one, or one year down to 6 months? What does it mean to have competitors who are 4 times faster than you? What would it mean to be 4 times faster than your competition...?
