Split it into bite-sized chunks that each deliver value.

Because small is beautiful, there is a strong preference for small items, as they:

  • enjoy shorter short cycle times;
  • show more progress on the kanban board;
  • take less effort to complete;
  • are easier to understand;
  • are easier to test and accept;
  • provide a predicable and continuous flow that facilitates expectation management; and
  • make “past results are a guarantee for the future” come true, just like yesterday’s weather.

To be specific, in planguage this looks like:

Small Stories
Scale   Average number of days per item.
Meter   Track the number of days per item in a control chart.
Wish   ≤ 2 days
Goal   ≤ 3 days
Must   ≤ 5 days
Now   20 days
  1. Split items until:
    1. the item has exactly one crystal clear acceptance criterium (or scenario) specified in gherkin; and
    2. each feature consists of ≤ 4 user stories; and
    3. each user story has ≤ 6 tasks.
  2. Identify and discuss outliers during or right after the daily standup.
