Software Development Life Cycle And Quality.

In this article I’ll take you through the world of software development and quality of software. SDLC is a framework for developing software of high quality at low cost. SDLC has six distinct phases i.e Requirements gathering, Analysis, Design, Coding, Testing and maintenance. Now let’s look at how to improve quality at each of the above phases. <ol> <li>Requirements gathering. Is the first phase in SDLC. In this phase requirements are collected from the stakeholders, including the end users. These requirements acts as an input for the development process, ensuring quality data is collected will lead to overall improvement of quality. Ensure that you collect data from a reliable source using efficient data collection methods.</li> <li>Analysis — The second phase in SDLC. This phase is all about analyzing and drawing meaningful information from the data collected in the previous phase. Ensuring that the analysis methods are up to standards will help you and your organization to achieve high quality information that will help in designing and development user friendly software systems.</li> <li>Design — The third phase in SDLC involves design interface for the software. The designers develop the user interface based on the information provided by the previous phases, you can already see how the entire SDLC is interconnected. In this phase you focus on the aesthetic aspect of the quality metrics , navigation and how users will perceive your application. Make sure the design is clean and users can navigate the software without much training.</li> <li>Coding or Development — in this phase the design is translated into a functional software. Here the aspect of the quality, your development team should focus on are realizability and conformance. Ensure that your codes doesn’t crash when wrong inputs were entered maybe through the input fields. Ensure the development approach used is in conformity with the established standards.</li> <li>Testing — In this phase the integration testing, unit testing and user acceptance testing takes place. Make sure that the testing is done correctly before software is delivered to end users. When it comes to quality user acceptance is very crucial. Make sure the software meets users expectations. Otherwise you can design and develop an expensive software but nobody wants to use.</li> <li>Maintenance — After testing is done, all the errors identified are corrected in this phase. Make sure that the system is maintainable. A high quality software should take less time and effort to repair and maintain.</li> </ol> <a href="https://bootcamp.uxdesign.cc/software-development-life-cycle-and-quality-7131379b52b">Read More</a>
