Software which doesn’t works or which is full of bugs is of no value, whether you develop your code using waterfall or agile it doesn’t matter. One of the fundamental principles of agile world confirms this “Working software over comprehensive documentation”. Agile follows the principle of satisfying the customer through early and continuous delivery of valuable software. This fundamental guideline/principle itself emphasizes the importance of the quality. If I talk in scrum terms all the stakeholders are responsible of quality. The Product Owner creates the story, gets the necessary feedback from customers and discusses the acceptance criteria with the team. When the team starts working on these stories, all these quality/acceptance criteria are verified within the sprint (and after the sprint by the customer). Any deviation is noted at the earliest and necessary actions taken.
The PDCA (Plan DO Check Act) cycle was made popular by Dr. W. Edwards Deming. This is a scientific cyclic process which can be used to improve the process (or product). This is cyclic in nature and usually time boxed. Plan This is the first stage of the process. During this step the team discusses the objectives, the process and the clear conditions of exit (conditions of acceptance). This stage sets the measurable and achievable goals for the team. DO Team works together to achieve the objective set in the planning phase. Team works with the set of agreed process. Check Once the implantation is done team regroups and verifies the output and compares it to the agreed conditions of acceptance decided during the planning phase. The deviation, if any, is noted down. ACT If any deviation in planned tasks is observed during the Check stage, a root cause analysis is conducted. Team brainstorms and identifies the changes required to prevent such deviatio...
