Scope of Software Development Life Cycle
Software Development Life Cycle (SDLC) or also called Software Development Process, provides a life cycle process for developing a software project, which consists of a detailed plan describing how to develop, maintain, replace and change or improve a specific software, that is followed by the software industry in order to meet or even exceed customer expectations.
Planning and requirement analysis is the first stage of the software life cycle process and is considered as the most important and fundamental stage in SDLC. In the planning and requirement analysis stage, the senior members of the software developer team gather as much information from the following sources: client company, sales department of the client company, market surveys and domain experts in the software industry, and the gathered information are then used to plan the basic software project approach, as well as to conduct product feasibility study in the economical, operational and technical areas such that the outcome of the technical feasibility study is to define the different technical methods that can be followed to implement the software project successfully with minimum risks.
The second stage process is called defining requirements which is done through a Software Requirement Specification (SRS) document which consists of all the software product requirements to be designed and developed during the software project life cycle and have these approved from the client company or from the market analysts of the client company.
The third stage is designing the software product architecture depends on the requirements specified in SRS, where more than one design approach is proposed and documented in a Design Document Specification (DDS). The client company's stakeholders review well the DDS and put in consideration the following: risk assessment, product robustness, design modularity, budget and time constraints, and, with these, the best design approach is selected for the software product.
The building or developing the Software for Small Business product is the stage four process of the SDLC where the programming code is generated based on DDS, such that developers must follow the coding guidelines, use programming tools like compilers, interpreters, debuggers, etc. and use a programming language, such as C, C++, Pascal, Java and PHP, with respect to the type of software being developed.
Stage five is the testing of the software product where product defects are reported, tracked, fixed and retested until such that the software product reaches the quality standards as defined in the SRS.
Stage six is the deployment of the software product at http://customsoftware.biz/ in the appropriate market in a limited segment and later tested in the real business environment and, based on feedback, the final and improved software product is released to a target market segment and its product maintenance is done for the existing customer base.
