Above is a list of activities that you go through when performing problem analysis. Start by identifying stakeholders for the problem. These stakeholders are people who are affected by the problem. Next, understand the root causes for the problem (the real problem behind the problem). Once the real problem (root cause) has been identified, get all your stakeholders to agree to a description of the problem.
Armed with a description of the problem, identify any constraints that may be imposed on any solution. These constraints typically limit the solution you may provide. Next, identify possible solutions for the problem. Let is important that you identify more than one possible solution. By doing this, you can then compare and contrast the solutions to find the best possible solution.

The analyst should be able to see if some aspects of information systems applications can help the business reach its objectives through addressing specific problems or opportunities. Phase two is determining information requirements. The analyst strives to understand what information users need to perform their jobs. Phase three is analyzing systems needs. Analyze system needs by creating data or process flow diagrams, document procedures, and etc. Phase four is designing the recommended system.
The systems analyst uses the information collected earlier in order to accomplish the logical design of the information system. Phase five is developing and documenting software. This works with users and communicates to the developers what needs to be programmed and documented. Phase six is testing and maintaining the system. A series of tests to pinpoint problems is run first with sample data and eventually with actual data from the current system. Phase seven is implementing and evaluating the System. This is reviewing and evaluating the system. This also involves training users to use the system.
