SYSTEM DEVELOPMENT CYCLE I

Systems analysis is the process of understanding in detail what a system should accomplish, how it will accomplish it required to accomplish it.

To be a good and successful systems analyst, the person must have the following skills:

  • Information technology knowledge and programming expertise.
  • Understand business problems.
  • Use logical methods for solving problems.
  • Ability to find facts about the problem and develop how it should be solved.
  • Always wanting the improvement of the system.

Systems Analyst Problem solving Approach

The steps taken by a system analyst to solve problems are stated below:

  1. Study and understand the problem: The analyst must identify that there is a problem to be solved and specify that it is feasible to solve the problem.
  2. Define the requirements for solving the problem: The analyst will identify the facts or data that are required to solve the problem.
  3. Develop a set of possible or alternative solutions: If there are alternative solutions, the systems analyst must develop them and decide on the best solution to use. However, in most cases, there may be only one solution which is chosen.
  4. Define the details of the chosen solution: All the facts and method need to solve the problem are specified in detail.
  5. Solve the problem: The problem is solved using the chosen solution method.
  6. Monitor to ensure that desired result or outcome is accomplished: Here, the analyst will make sure that the formula is not miscalculated.
