Following on from my previous blog I will now discuss the second stage in the Systems development life cycle: Analysis.
In this stage the current system is studied. This is done by collecting information from users. This data is gathered using different methods, 1. Traditional methods: this consists of observation, interviews and surveys. 2. Modern methods: this consists of joint application design, prototyping and group decision support systems. 3. Radical methods: this consists of business process re-engineering. The system analyst needs to identify what the users want in this new system. The users are the most important people when it comes to designing the system because they will be the ones using it. It is up to the analyst to ensure it meets all their requirements and is user friendly, this will help ensure the introduction of the system runs smoothly and has a positive effect on the business. The main outputs of this stage are the formal requirements documents, dataflow diagrams and entity relationship diagrams of current system.
Thanks🙂 Blog again soon.
