    • Essentials of the Software Development Life CycleThe technological era has created a demanding customer who brings in a number of challenges fortodays enterprise. Since aggressively competitive world today depends on information technology, toencounter the challenges on a winning note, the enterprises further bank on technological innovationsto deploy world-class infrastructure and customize the software applications.Designing and developing software application requires a high level of understanding of thedevelopment process. Essentially made of a series of steps or phases the Software DevelopmentLife Cycle (SDLC) describes the tasks that are performed during the software development process.Based on a format followed by the development team it comprises of a detailed plan for developingand retaining the software. The life cycle is about the entire development process and themethodology applied for improving the software quality.The software development life cycle starts with the initiation, analysis and definition phases,wherein the purpose of the software or system is determined, the goals established, to the design,development phase followed by testing and implementation till disposal. This manual penetrationtests conducted during the testing phase ensure that the software developed cannot be exploited incase of a security breach. The SDLC solution from the leaders in the industry segment helps thesoftware development teams overcome the complexities involved in the process. Further, thestructured and standardized process for all the phases ensures that the strategic goals are achieved.However, with several models available to streamline the software development process, enterprisestend to choose any one or a combination of models. The models available include: • The waterfall model: a process, where developers are to follow these phases in order and proceed to next only after finishing the previous one. • Spiral Model: This model emphasis on the conditions of options and constraints to support software reuse and quality and involves in regular risk management during the development process. • Iterative and incremental development: involve in development of portions of software irrespective of the order to help uncover important issues early. • Agile methodology: With iterative development as the basis, this uses the feedback from regular tests and releases of the software as the control mechanism rather than planning.However, developing best-of-the-breed software applications requires number of tools. To achievehigher productivity and quality it is necessary to go in for integration of the development tools. Thesoftware development life cycle makes use of a number of tools for its various functions. Theseinclude the requirements management tools, test management, issue management, riskmanagement, release management and project management tool. Further for functions such asconfiguration and build management it makes use of third-party tools. Such solutions assure theenterprises of high-end software with management reporting and controls that will increase theproductivity levels.Other Links - requirements traceability matrix
