ArrAy captures information in a centralized Knowledge Repository that is customized for each customer and made available to them via ArrAyWeb. The Knowledge Repository promotes institutional learning and applies the ArrAy Way methodology to nurture collaboration, quality and productivity. ArrAy follows a scientific approach in which team members:

• Study the phenomena
• Pose hypotheses and test them
• Inspect the results
• Determine if a hypothesis holds true
• Implement a solution
• Further test and inspect the system to ensure the validity of the solution
• Review this solution, challenging it from a variety of technical viewpoints
• Retain the solution as a valid implementation

Throughout this disciplined process, the team documents all the knowledge they acquire, and the knowledge documents are retained in a Knowledge Repository that is available to all team members. As ArrAy teams work to resolve engineering issues, they continuously accumulate valuable information about software projects and the steps taken throughout the software lifecycle.

The ArrAy Work Activity Document (WAD) functions as the heart of the Knowledge Repository. As ArrAy team activity progresses on an engagement, team members continuously accumulate valuable information about software activities and the steps taken to address ongoing engineering challenges. This information is kept in an online WAD. Team members record all their hypotheses, strategies, plans, findings, tests, test results and implemented actions into the WAD.

During the engagement, customers can access the WAD via ArrAyWeb with any browser, enabling them to share the same view of the work-in-progress as seen by ArrAy team members. The WAD also becomes the nucleus of a central Knowledge Repository about software engineering that remains with customers after the engagement, providing a lasting transfer of knowledge that is independent of staffing.

Team members continuously contribute to the Knowledge Repository, and it is used to manage programs and personnel. Customers have real-time access to their Knowledge Repository via ArrAyWeb so they can monitor activities, instantly analyze progress and schedules and communicate with ArrAy.
