| Starting with prediction number 1, we find that our prediction does not pan out. Looking at the chart below we see that the most increase was with low churn was in fact higher than the no churn team, whereas, as expected they both had more increase than the high churn team. | Starting with prediction number 1, we find that our prediction does not pan out.

| We need to dig a little deeper to understand what is happening here. Interviews with the management involved in these changes revealed that there are differences in what happens based on who is being added or subtracted from the team, that there is a place for judicious change: | We need to dig a little deeper to understand what is happening here.

| Turning to the second prediction, that if you add or subtract a person from a high churn team, you basically have a similar increase or decrease in velocity going forward (since teams members have not jelled so the total ability of the team is simply the sum of the parts.) This prediction basically pans out. Subtract one team member reduces the velocity for high churn teams, while adding a team member increases the velocity. | Turning to the second prediction, that if you add or subtract a person from a high churn team, you basically have a similar increase or decrease in velocity going forward (since teams members have not jelled so the total ability of the team is simply the sum of the parts.)

| Note that I would ignore the results for the “-2” and “2”, “3” as the number of teams that actually went through this level of change are 3 or less in each case (versus more than 20 for the “-1” and “1”) case. | Note that I would ignore the results for the “-2” and “2”, “3” as the number of teams that actually went through this level of change are 3 or less in each case (versus more than 20 for the “-1” and “1”) case. | ||
