Knowledge Management (KM) in the Software Development Life Cycle (SDLC) integrates the processes of creating, capturing, sharing, storing, and applying knowledge to improve efficiency and quality throughout a project. By embedding KM into each phase—initiation, requirements, design, development, testing, and closure—organizations can reuse best practices, enhance collaboration, reduce risks, and ensure continuous improvement. This approach not only strengthens planning and execution but also improves product quality, client satisfaction, and team onboarding, supported by tools like Redmine, Google Drive, ZyxPM.
