This methodology is characterized by its iterative approach, allowing india mobile numbers list teams to make incremental changes and evaluate their effectiveness before implementing them on a larger scale. It essentially serves to plan and implement changes systematically. As we saw in Simon Sineck's golden circle , it can be applied in various areas and projects as a simple way to guide people and teams in the execution of actions.
1. Planning (Plan)
In the planning stage, the team identifies a problem or an opportunity for improvement. This involves a deep analysis of the current situation, identifying clear objectives, and formulating a detailed plan to achieve these objectives. In the context of software development, this could include defining new system requirements, planning sprints in agile methodologies, or identifying improvements to the development process.
Example: A development team notices that the response time of their web application is too slow. In the planning phase, they decide to investigate the causes of the problem and design a plan to optimize performance.
2. Execution (Do)
In this phase, the plan is put into action. The planned changes are implemented, whether to the software code, development processes, or team work practices. It is crucial that these changes are made in a controlled environment to minimize risk and allow for accurate assessment of the results.
Example: The team implements code improvements to optimize database queries and reduce server load, testing these changes in a development environment before deploying them to production.
3. Verification (Check)
Once changes have been implemented, it is critical to evaluate their effectiveness. In the verification phase, the team collects and analyzes data to determine whether the changes have achieved the desired results. This may involve performance testing, user satisfaction surveys, or analysis of key metrics.
Example: After implementing optimizations, the team performs load testing and monitors the application's response time. They compare this data to previous results to check if there has been a significant improvement.
