Both the Cost/Benefit Analysis and the more detailed Systems Analysis depend on investigating the requirements of the proposed system requested, followed by definition of these requirements in the Requirements Catalogue and subsequent modelling and refinement of these requirements. SSADM (Structured Systems Analysis and Design Method) envisages the following sequence of stages:
Wote Gharama / Faida Uchambuzi na kina zaidi Systems Analysis hutegemea uchunguzi mahitaji ya mfumo wa mapendekezo ombi, ikifuatiwa na ufafanuzi wa mahitaji hayo katika Mahitaji Catalogue na baadae modeling na ustaarabu wa mahitaji hayo. SSADM (Strukturerad Systems Analysis and Design Method) inalenga mlolongo zifuatazo hatua:
