System Development Life Cycle
(SDLC) is the process of implementing or updating a system. It includes six steps which starts with studying a system and is finished when the new or updated system is in place. At each stage in the cycle a decision is made whether or not to continue to the next phase.

Development
Life Cycle
(SDLC)
When the plan for a new system is developed or if an existing system requires a modification, the first step is to perform a preliminary investigation. The purpose of the preliminary investigation is to identify:
Nature of the problem
Possible solutions
Approximate costs
Benefits of each proposed solution
The end result of a preliminary investigation should include a
Feasibility Report

System analysis performs an in-depth study of the problem area and will include factors like the needs of the system users and the adequacy of the current system. The main takeaways from system analysis are data collection and data analysis.
Data Collection should be focused on gathering useful data about the system being studied. Helpful information includes how the system is intended to work, reviewing organizational charts, sending questionnaires to users, and observing those who use the system
