SDLC methodology: A sneak in to the design and analysis of software
It is a well known fact that information technology industry has been growing at a very fast pace in recent times. People from different spheres of economy have contributed their knowledge in designing systems which are able to manage different aspects of the business in a major manner. SDLC methodology involves different stages that form integral components of the software creation process. Generally a company follows different sets of criteria which help in designing the software in easy and hassle free manner. Requirement gathering is a very crucial cog in the wheel that would go a long way in creating system requirements and specifications document. Similarly design and validation are also carried out to ensure that the software is able to meet the rigorous requirements of the clients. If system development life cycle is followed it would drastically reduce the overall cost which will impact the total price of the application when it enters the market.
Different aspects of SDLC:
If you undertake a deep analysis you will find that software which is launched in the market should run on different systems. Due to various platforms it becomes a problem for various hardware and software to effectively communicate with each other. In order to manage different heterogeneous models experts have proposed different variants of SDLC methodology like Cascade which is very famous among the software developers. Similarly Spiral rule is also followed that results in continuous enhancement of the capabilities of application launched in the market. Prototype is regarded as a back bone which could be used in obtaining more requirements from the clients so that final system is evolved in to a mature product. Major operating systems are designed in similar manner that makes them more effective and would go a long way in boosting productivity of the organization.
Early SDLC model and its drawbacks:
In the initial phase of software development many companies followed sequential methodology called water fall model which consists of various stages like analysis, design, coding and testing. One of the major disadvantages of the above system is that it was not possible to rectify faults if they were detected at design stages. Therefore great emphasis was laid on the analysis phase so that developers knew exactly the requirements of the clients however tracking errors became a costly proposition since process had to be restarted all over again. Due to increased competition among different companies who are jostling for space in the information technology market Rapid application development plan was initiated that used iterative model of development to exceed expectations of the ever demanding customers.
Maintenance is a very crucial aspect that requires lots of attention from companies because very few developers provide them at an efficient cost. Therefore if you are looking to place an order for purchase of the application you should interact with organizations that have required skill sets for after sales support. It would go a long way in making you feel secured and satisfied. Cost might be on the higher side but the deal would enable you to boost profitability and efficiency.
