Step-by-step explanation:
The first step in the System Development Life Cycle (SDLC) involves defining the problems that the IT system should address, examining various alternatives, and reporting the findings. This step is referred to as the problem definition step. In this step, the needs of potential customers are investigated, competitors' market positions are characterized, and constraints on the design effort such as available personnel, time, and money are established.
