SDLC methodology for designing a system Essay Example for Free

SDLC methodological analysis for designing a system EssayThe primary aim is to evaluate the SDLC methodology for designing a system. Prior to building a system, a set of methodology is essential in keeping the process bitch in right force so that it adheres to entire coverage and successful completion of tasks. It demands professional approach in planning, building and operating a system. SDLC methodology which encompasses several techniques in making the system travel smooth, processing the various steps required in putting together a system successfully. The reel model which is a flavor of SDLC techniques corresponds in designing a system where job requirements be volatile in nature and communication with remote entities is a priority. The verticillate model would take into account all the primary steps in building a deliverable every time it completes a circle. erst it is finished with the planning and analysis phase the risk analysis task is taken in the picture. It i s followed by engineering, construction and release, client evaluation and finally customer communication. Once a round of drinks is covered, it results in a deliverable which is further processed upon customer communication and feedback.The SWOT analysis of the spiral model would canvass the coverage of whether it can be taken up as a viable option in designing a system. The following is the analysis Strengths The business environments are seldom volatile in nature where the requirements are ever changing and are adding every moment to expand their scope and stay combative in the market. The spiral model would shuffling sure that the proposed system is prone to changes. It provides enough mechanism to take into account the changes in the customers environment and act accordingly. foreign other SDLC methods where the business requirements are completely taken as standstill when taking into account the building of the system. Unlike the waterfall model where the design stages ar e non-reversible in nature, once the stage is surpassed it cannot be revisited again. Weaknesses The weaknesses of the spiral model are that it is sooner expensive in nature as every deployment is revisited with the spiral cycle once it receives a customer communication and feedback. It demands quite risk assessment expertise. The time taken to build the complete system is considerable high as for every new requirement is cycled all through from planning to implementation. The consumption of resources is substantially large as all the developmental stages are followed for creating a pas seul of the system in every cycle. Opportunities The opportunities of using the spiral model are relatively high in comparison to the other models in use. The business external environment is fast changing to the requirements and enveloping newer challenges to analyze their market and take risks to prosper. In this situation having a flexible system development strategy would make it easy to design and build a system susceptible to frequent changes with changing business requirements. Taking into account the other methods available in the market, the spiral model would stand out in the crowd. Threats The other prototyping methods like RAD and Incremental methods of SDLC pose a threat to spiral method. The incremental approach is quite complex in operation scarce its flexibility is quite high in solving discrepancies. The RAD methodology is quite popular in SDLC but is not prone to taking the frequent changes into consideration which is a drawback.
