Which phase includes gathering user input and reviewing specifications?

The planning phase is crucial in the software development life cycle as it lays the foundation for the entire project. During this phase, gathering user input is essential to understand the needs and requirements of the target audience. This involves not only collecting direct feedback from users but also analyzing existing specifications and proposals to determine what features and functionality should be prioritized.

Reviewing specifications is also a key activity in this phase; it ensures that everyone involved has a clear and shared understanding of what the project aims to achieve. This process of gathering input and reviewing documentation helps in identifying potential gaps or areas for clarification early, which can ultimately lead to a more successful outcome as development progresses. By establishing a comprehensive understanding of requirements upfront, the team can allocate resources more effectively and set realistic timelines for subsequent phases of design, development, and testing.
