Which phase in the systems life cycle involves gathering and analyzing data?

The phase in the systems life cycle that involves gathering and analyzing data is the "Analysis" phase. Here are the steps:

1. Identify the Problem: The first step in the analysis phase is to identify and understand the problem or the goal of the system. This involves understanding the needs of the users and the business, and the problems that the system is expected to solve.

2. Gather Information: Once the problem is identified, the next step is to gather information. This involves collecting data about the problem, the users, and the business. This data can be collected through various methods such as interviews, surveys, and observation.

3. Analyze Information: After the data is collected, it is then analyzed. This involves examining the data to understand the problem better and to identify the requirements of the system. This can involve statistical analysis, data modeling, and other analytical techniques.

4. Document Requirements: The final step in the analysis phase is to document the requirements of the system. This involves creating a detailed description of what the system should do, how it should work, and what it should look like. This document is then used as a guide in the design and development of the system.
