Our big spike is due to all the items being placed on the backlog (TODO) - although some of these may never be implemented more on this in the future!
To summarize some of the information I can see (and you can't!):
Average Lead Time for any sized item from inception to live:
- 35 days - 7 and 11 items in progress
- 21 days - 2 and 5 items in progress
- Variability in size has an impact on lead time - large items increase lead time.
- Increase in Work in Progress decreases lead time.
