Get a big thing done.

Therefore:

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
Therefore	Split items until: the item has exactly one crystal clear acceptance criterium (or scenario) specified in gherkin; and each feature consists of ≤ 4 user stories; and each user story has ≤ 6 tasks. Identify and discuss outliers during or right after the daily standup.
