Scrum Table Berlin
Posted: | More posts about Scrum Event General
Last week I attended the scrum table Berlin. This time around Phillippe gave a presentation on "backlog colours", that is types of work items tracked in the backlog.
The easiest type to track are features - that is items that generate revenue and are on the wishlist of the customer. Second type of items he sees are infrastructure items - that is, things needed to implement several features but invisible to the customer. Third type are bugs. Basically these are diminishing the value of features one had already classified as done earlier in the process. Fourth and last type are technical debt items - that is shortcuts taken or bad design choices (either knowingly as intentional decision made to meet some deadline or unintentional due to lack of experience).
A very simple classification could be the following matrix:
|Technical Debt||Invisible Negative||Positive|
All four types of items exist in the real world. The interesting part is making these visible, assigning costs to each of them and scheduling these items in the regular sprint intervals.
