Any problems can be swiftly uncovered, corrected, and action taken to prevent their re-occurrence. However, it can be seen that the Definition of Done is not asserted atomically just prior to release, but rather at each point where effort has been invested in development and value is being added. The wider “Definition of Done”, which relates to the completed increment, would comprise these and all levels of “Done”. Such criteria would represent an additional level of “Done” to be satisfied before work-in-progress can be committed and integrated. Before that work can be committed to a repository though, it might have to be peer reviewed, documented, or expected to satisfy a particular type or degree of test coverage. Sometimes this particular level is referred to as “Story Done”. For example, if a user story is being implemented then it is reasonable to expect that all of its acceptance criteria ought to be satisfied.

The opportunity for complex rework to accumulate, and for waste to be compounded, is thereby reduced.Ī software development team can also use multiple elevations of “Done” in order to inspect and adapt work on an ongoing basis, and thereby assure quality in the timeliest possible manner. Defects or other problems can be detected and resolved as close as possible to the time and place of the work being carried out. Testing at multiple discrete points on the assembly line, each time significant value is added, reduces the magnitude of such risk. Extensive re-work might be necessary by that point.
The risk of finding problems so late in the day would clearly be high, and the opportunity to provide meaningful remedy at such a late stage would be limited. The testing of components as they are brought together is not likely to be deferred until the car finally rolls off the assembly line. In a car factory for example, quality is likely to be inspected on an ongoing basis as work is completed. There’s nothing to stop the evidencing of “Done” from being built up gradually as work is performed, and there can be distinct advantages in doing so. However, this does not imply that “Done” must be an atomic and indivisible measure. The Definition of Done sensu-stricto must of course pertain to the increment, since that is the artifact which is ultimately subject to release. The Scrum Guide tells us that there can be multiple levels of “Done”. This will give stakeholders an improved picture of how much work genuinely remains to be completed, and of the gaps which lie between the current operating model and robust agile practice. Any technical debt incurred as a result of that deficit may then be tracked, so the nature and extent of it can be understood. A team which runs with a deficit for release cannot be said to be operating in an agile manner, since no increment will be released and inspected and adapted, and this must be recognized.
A Definition of Done is instrumental to achieving transparency, and of course any “deficit for release” should be made equally plain. Only then can shortcomings in the standard for release be acknowledged and remedied. Hence a Definition of Done must be articulated clearly, no matter how shoddy it might be. In other words, an increment is not truly complete if it is not of immediate release quality, since more work must be done before the value invested in it can be leveraged. Any such technical debt will need to be tracked, managed, and “paid off” by completing the outstanding work so the increment is finally brought up to snuff. Perhaps there might be further tweaks to be done, or optimizations, or tests, or integration work with the wider product. Additional work will need to be carried out before the increment under development is truly usable. This debt reflects the fact that certain things still need doing, no matter how small or trivial they might be held to be. Can a team’s output actually be deployed into production and used immediately, or is any work still outstanding? We saw that a team’s Definition of Done will often fall short of this essential standard, and “technical debt” will be incurred as a result. That’s the acid test of what “Done” ought to mean. “The secret of success is to be ready when your opportunity comes” - Benjamin DisraeliĪ few weeks ago we looked at the Definition of Done, which describes the conditions which must be satisfied before a team’s deliverables can be considered fit for release.
