![]() ![]() What is a weak “Definition of Done” and what are the consequences of it?Īnything less than the ideal definition of done will be considered to be a weak definition of done. There will be no one to supervise or validate this but it is the Development Team’s responsibility to ensure all items that are worked within a Sprint should meet the “Definition of Done”. They must ensure every item they work on the Sprint should satisfy all the criteria of their “Definition of Done”. The Developers are responsible to conform to the “Definition of Done”. Who should conform to the “Definition of Done”? This ensures the same level of quality is maintained by all teams. However, when any team says they are “Done” with an item, that item must satisfy the common definition of done agreed by all teams. On top of that each team may add some additional items that may be specific to their team. So if there are multiple teams working on the same Product, then they should have a mutually agreed common “Definition of Done”. The “Definition of Done” is applied for the entire Increment. ![]() Can different teams work on the same Product have different “Definition of Done”? If the Definition of done gets changed, then the previously completed increments’ features must be brought to the current Definition of Done. As the Scrum Teams mature, their “Definition of Done” should be more strengthened. Sprint Retrospective is a formal opportunity for the Scrum Team to inspect and adapt their Definition of Done”. No, the Definition of Done can change based on the need. ![]() If the organization has any pre-defined quality standards such as “for every 5 KLOC there will be only 3 severity 1 defects” then those standards must be included in the definition of done and on top of that, the Scrum team can choose additional criteria. The Scrum Master facilitates the creation of the Definition of Done. It helps the Developers to forecast work for the upcoming Sprint. The Scrum Team together agrees to the Definition of Done and typically if it is created before the first Sprint begins. They should have a shared understanding on what kind of quality criteria the increment should have. The Scrum Team (Product Owner, Scrum Master and Developers) together create the Definition of Done that helps them to create a potentially releasable product increment. Who will create the “Definition of Done” and when? Acceptance criteria can vary for different Product Backlog items but the quality criteria will be mostly same for all the Product Backlog items. But the quality criteria will be decided by the Developers. For example, in the above “dinner” scenario, what items have to be consumed for dinner will be the acceptance criteria and it will be decided by the Product Owner. The Acceptance Criteria is related to the functionality whereas the Definition of Done is related to the Quality. What is the difference between Acceptance Criteria and Definition of Done? For example, if you build a house, the quality criteria may be different than building a software Product. This quality criteria can be different for different types of Products. It helps achieve a shared understanding between the Product Owner and the Developers on what “Done” means. The purpose of the Definition of Done is to decide whether a Product Backlog Item can be made part of an Increment or not. ![]() It is a formal description of quality criteria checklist. That means, each Increment that is created in a Sprint should meet the “Definition of Done”. The “Definition of Done” is a “commitment” for the Product Increment. If any of the above items are not done then the dinner is not done. If the above criteria is met, then the dinner can be considered as “Done”. Switch off the light and fan/air conditioner in dining area.Eat the dinner with: A soup, starters, main course, desserts.Let us take a scenario: What is the criteria that helps you to decide whether your family dinner is “done” or not? Below will be the probable criteria: So in this article, I am attempting to make this concept clear through a simple example. This is the most confusing topic also for most of the Scrum teams. The “ Definition of Done” is a formal description of quality criteria for the Scrum teams to have a shared understanding of what “Done” means for the Increment. ![]()
