Example

Sprint 1 dates: Jan 2 - Jan 15

Sprint 2 dates: Jan 16 - Jan 30

Sprint 3 dates: Jan 31 - Feb 13

Sprint 4 dates: Feb 14 - Feb 28

Sprint 5 dates: Mar 1 - Mar 15

Story1 was created on Jan,1 and planned for Sprint1. The team started working on it on Jan, 5 and then on Jan, 10 it was decided to suspend development and remove it from the scope. Then on Feb,3 it was decided to work on in in Sprint4. It was started in Sprint 4 and finished on Feb, 20.

Story2 and Story3 were created on Feb,13, taken into Sprint4 iteration . Story 2 completed on Feb,25. Story 3 was completed on March,2.

Cycle Time for Story1 is Feb,28 - Jan,2 = 58 days, as Sprint4End - Sprint1Start

Cycle Time for Story2 is Feb,28 - Feb,14= 14 days as Sprint4End - Sprint4Start

Cycle Time for Story3 is Mar,15 - Feb,14 = 29 days as Sprint5End - Sprint4Start

Cycle Time for Sprint 4 = (58+14)/2 = 36 days

Cycle Time for Sprint 5 = 29/1=29 days

Unusual cases:

1 Issue completion date is earlier than a sprint start it is assigned to: issue SCT_sprint is calculated by a sprint lifetime issue completion date is covered by.

2 Issue completion date is later than a sprint finish it is assigned to: issue SCT_sprint is calculated by a sprint lifetime issue completion date is covered by.

3 Project has several 2 active sprints in the same time and one of the sprints is started later and finished early then other. Issue is assigned to this short sprint ans done and completion date in frame of it: issue SCTsprint is calculated by a sprint with later end date. Assigned sprint is not affected
