Identification of Need
The 1st step of the system analysis procedure involves the identification of requirement. The analyst system engineer meets with the customer and the end user if different from the customer. Customer may be a representative of an outside organization the marketing department of the analyst's organization when a product is being established or another technical department when an internal system is to be established. Like information engineering the intent is to understand the product's goal and to describe the target wants to meet the goal.
Once overall target are identified the analyst moves on to an evaluation of supplementary information that are: Does the technology exist to build the system? What special manufacturing and development resources will be needed? What bounds have been placed on schedule and costs? If the new system is really a product to be established for sale to various customers the following questions are also asked that are how does this product compare with competitive products? What is the potential market for the product? What position does this product take in the overall product line of the organization?
Information collection during the requirement identification step is specified in a system concept document. The real concept document is sometimes built through the customer previously meetings with the analyst. Regularly customer-analyst communication results in changes to the document.
