With a goal of meeting and exceeding the customer’s expectations, Software Development Life Cycle (SDLC), also called Software Development Process is a framework of processes, that is designed and followed by the software industry, which consists of a detailed plan describing how to develop, maintain, replace and change or improve a specific software.
Considered as the most important and fundamental stage in SDLC is the planning and requirement analysis which is the first stage of the software life cycle process. In the planning and requirement analysis stage, as much information is gathered by the senior members of the Line of Business Software developer team 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.
Called defining requirements, the second stage process 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.
Designing the software product architecture is the third stage process which depends on the requirements specified in SRS, where more than one design approach is proposed and documented in a Design Document Specification (DDS). The best design approach is selected for the software product after reviewing well of the DDS by the client company’s stakeholders putting in consideration the following: risk assessment, product robustness, design modularity, budget and time constraints.
The building or developing the software 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.
The testing of the software product is the stage five of the SDLC 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 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.
