During this step, the software analyst’s job is to work with strategy makers to establish an agreed upon definition of the project’s scope and define its goals and related objectives. Step two requires specifications definition. The analyst makes refinements to previously define goals during this step. Functions of operations for the software application will be broken out here.

They provide detailed level information on the SDLC process, layouts of each screen, relevant business rules and standards, diagram process and DFD, pseudo-code and other related documentation. Step five is called implementation and is where the actual program code is written and developed. This work is divided and assigned to specific team members. Step six is called integration and testing. During this step the developers bring together of all the developed modules into one coherent system and test case studies for errors, interoperability and bugs. There are standard testing methods that are applied for this step. Step seven involves the operation of the SDLC product. The team imports the software package onto an end-user unit and runs the business target data sets. Step eight is the maintenance of the product to...
