By following these practices during the implementation iteration, teams can efficiently develop working software that meets the goals set for each cycle.
Key Aspects of Implementation Iteration
-Focused Development: During implementation, the team focuses on developing the functionality outlined in the planning and design phases for that specific iteration. The goal is to meet the minimum requirements defined for the current cycle.
-Time-Boxed Approach: Iterations are usually time-boxed, meaning developers have a set period to complete the implementation. This helps keep the project on track and encourages efficient work.
-Building on Previous Work: Each implementation iteration builds upon the work done in previous cycles, gradually adding more features and improving existing ones.
Steps in the Implementation Phase
-Code Development: Programmers write the actual code based on the technical specifications and designs created earlier.
-Unit Testing: As features are developed, developers perform unit tests to ensure individual components work as intended.
-Integration: New code is integrated with existing work from previous iterations.
-Continuous Integration: Many teams use continuous integration practices to frequently merge code changes into a central repository.
-Documentation: Developers document their work, including any APIs, functions, or important code structures.
Best Practices for Implementation
-Prioritize Features: Focus on implementing the most critical features first, ensuring that each iteration produces a potentially shippable product increment4.
-Maintain Code Quality: Adhere to coding standards and use practices like code reviews to maintain high-quality code throughout the implementation.
-Regular Communication: Hold daily stand-ups or check-ins to discuss progress, challenges, and any needed adjustments to the implementation plan.
-Flexibility: Be prepared to adapt the implementation approach based on new information or challenges that arise during the iteration.
Transitioning to Testing: As the implementation phase nears completion, the team prepares for the testing phase:
-Prepare Test Environment: Set up the necessary testing environments that mirror the production setup.
-Create Test Cases: Develop test cases based on the requirements and expected functionality.
-Handoff to QA: Transfer the implemented features to the quality assurance team for thorough testing.
By following these practices during the implementation iteration, teams can efficiently develop working software that meets the goals set for each cycle, setting the stage for effective testing and review in the subsequent phases of the iterative process.
