Defect Debt

On an Agile project defects are fixed as they are found, so no story should be considered complete if there are outstanding defects with it. But this does not mean that defects do not persist. A defect may be found that is not related to a story in the current iteration, or the customer may decide that the defect on a story is not worth the effort it would take to fix it and would prefer to focus on another story.

In this way a team can start to accumulate defects, which I classify as defect debt.

Defect debt is just like technical debt. It is behaviour that the customer has not asked for. In fact I would suggest that defects are technical debt, they generally exist because of the way code is working, or the lack of code to handle a situation. In some cases defects are not fixed as they are extremely difficult to fix, so the customer would prefer to focus the effort elsewhere. Often these defects would require significant changes to the code.

I suggest that defect debt should be handled in the same way as technical debt. Defects that will not be addressed immediately should be captured as separate cards and fixed whenever possible without impacting velocity. So when a pair is in an area of code that contains a defect, or a pair has some spare time at the end of an iteration. Of course if a customer decides a defect is important enough then they can schedule it for fixing and treat it like a story, but the team should make all efforts to reduce the amount of defect debt they create.

    I do not agree that defects should be added to scope, this to me is saying that the mistakes the team makes should be covered by the customer. Defects are by nature not what the customer asked for and therefore the team should not ask the customer to pay for them. By adding them to scope there is the chance that the team will no longer see defects as their problem and instead hide them within the scope of the project. The team needs to take responsibility for the defects and do what they can to reduce the defects they are creating and the impact those defects have on the project.

    I prefer to look at unfixed defects as simply additions to scope. If a defect is not related to work currently ‘in progress’, then a change to the system needs to be made to correct the defect. This is analogous to a new story (traditional scope) that requires a change to be made to the system to implement it. In both situations, you can estimate and track in the same way, and they both affect the overall amount of work required to deliver a ‘completed’ project in the same way. This also allows the business to prioritise when a defect gets fixed (if at all), the same way they do with new stories.

    This is different from technical debt, which is not normally captured as discrete, independent work to be completed. Attempting to recover technical debt is usually considered when implementing any story that affects the area of code where the debt has been incurred.

    I’d like to experiment on a project by tracking defects-not-related-to-current-stories as ‘discovered scope’ (whilst clearly flagging that it is scope caused by a defect rather than a new feature).

    I agree with you Kristen, the defect debt should handle like technical tasks within a team, this gives a clear vision of defects that has been created and how much effort needs to fix them.
