Analysis
Akopọ
Before a single line of a new system is built, someone has to find out exactly how the present way of working really works, where it goes wrong, and what the people who use it actually need. That detective work is the analysis stage, the first stop in the systems life cycle. Get it right and everything that follows has a firm foundation; get it wrong and the finished system will solve the wrong problem.
In this lesson you will learn the four ways an analyst researches a current system, when each one is the right tool, and the advantages and drawbacks of each. You will then see how the analyst records what they find, separates the inputs, outputs and processing, pins down the user and information requirements, and finally justifies the hardware and software the new system will need.
