A lot of emphasis is given to the implementation of agile process and technical understanding for the success of a project. No one will argue that everyone has been benefited from agile methodologies, which really helped to reduce the waste in project execution and increase the probability of project success. In a similar manner, the importance of technology is also highlighted, right from the project inception, designing the architecture, choosing the framework, development of software, and the deployment of software.

With all the improvement in processes and the importance given to technology, teams faces fewer technical and process challenges. Although a lot has been done to improve the functional understanding of the team, most of the defects raised during development cycle are due to an understanding gap in business logic. 

Here are few best practices that can be implemented by teams to reduce functional defects:

  • Regular functional grooming for changing team: As team members keep changing, regular grooming of the entire product helps to improve overall functional knowledge. The Product Owner may schedule and drive weekly meetings to discuss various modules of product.

  • Review of an epic whenever its story is committed: Big epics are decomposed in several user stories, which are distributed across sprints. While grooming user stories for each sprint, each epic should be discussed in its entirety along with the story. It helps to discuss changes in the epic and if there are any changes in the requirements, new stories can be created to make the appropriate change.

  • Active participation of testing team in grooming sessions: Doubts or clarification that testing team may need addressed at a later stage of a sprint or functional gaps which might surface during integration testing have a higher chance of getting detected during grooming sessions, but only if testing team members are active participants in the sessions. 

  • Encouraging disciplined use of technology & tools: Disciplined use of tools like JIRA (or VersionOne) during the entire delivery cycle (epic elaboration, story elaboration, grooming, development, and testing) to link different stories and epics which are related to each other and to track discussions, helps identify dependencies earlier which helps in better overall release and sprint planning to avoid unwanted defects.

  • Vertical decomposition of user stories to smallest shippable size: Vertically decomposing user stories to their smallest shippable sizes helps to limit the focus of the developer and creates less noise, waste, and dependencies. It helps to complete the stories faster and also to reduce defects.

  • Explain value add by user story: Whenever a user story is groomed, the value added by a user story should be explained. It is a very important aspect of functional grooming, as it helps developers  understand the reason behind the change. If there is dependency on some other modules, developers can highlight during grooming.

  • High availability of Product Owner: One of the most important factors for the enrichment of functional knowledge of team, the proximity of the Product Owner helps team members to clarify their doubt immediately, which helps to reduce assumptions made by developers and consequently reduces defects in the application.

  • Walkthrough of user interface: It has been observed that if a walkthrough of user interface is done during sprint planning, less clarification and defects are raised mid-sprint. It also reduces unnecessary communication between the team and product owner.

Eventually with a reduced number of avoidable defects, the overall product quality improves and time to market the product reduces.
