How to choose a methodology that will work for you?<\/li><\/ul>\n\n\n\nThis article explains the variety of SDLC methodologies and provides the answers to all the above questions.<\/p>\n\n\n\n
Waterfall Development<\/h2>\n\n\n\n
The Waterfall model is most likely when you think about when you try to imagine a structured software development cycle. It\u2019s linear and sequential. That is, it consists of a number of consecutive stages that don\u2019t overlap. The next stage isn\u2019t going to begin until the current one is finished.<\/p>\n\n\n\n
Everything begins with requirement analysis. This is the first step that might sound obvious but is, in fact, so crucial to overall success it can\u2019t be overestimated. When all the requirements are clear, it\u2019s time to start designing the system. Then, implementation follows. As soon as the system is ready, it\u2019s tested to ensure appropriate quality, after which it can be launched via the deployment process. This is the last but one stage, followed only by maintenance aimed at keeping the system up-to-date.<\/p>\n\n\n\n
The Waterfall methodology offers the advantage of rigid planning and management, on the flipside of which there\u2019s a lack of flexibility that the team might need to deal with requirement and priority changes post requirement clarification. This rigidity is the key reason why Waterfall has been losing its popularity.<\/p>\n\n\n\n
The V-Shaped Methodology<\/h2>\n\n\n\n
The V-Model is a variation of the Waterfall methodology, which means it\u2019s a set of sequential stages. However, it adopts a more thorough approach to quality assurance by introducing a testing session at the end of each stage.<\/p>\n\n\n\n
This large-to-small methodology relies heavily on verification as validation and works well for relatively simple projects. However, it\u2019s not the most efficient methodology when it comes to dealing with complexity, concurrent events, and iterations.<\/p>\n\n\n\n
Agile<\/h2>\n\n\n\n
It would be inaccurate to designate Agile as an SDLC methodology. Rather, it\u2019s a set of approaches that share a common characteristic that gave it its name. In the context of software development, agility refers to the model being flexible enough to adjust to requirement alterations on the go.<\/p>\n\n\n\n
Scrum<\/h3>\n\n\n\n
A lot of people use the terms \u201cAgile\u201d and \u201cScrum\u201d interchangeably. This is far from correct but reflects the popularity of Scrum as a member of the Agile family.<\/p>\n\n\n\n
Simply put, Scrum is an iterative framework that comes with a small set of roles and time-boxed ceremonies that enable its three pillars, which are transparency, inspection, and adaptation. Each iteration, or sprint, delivers an increment to the product\u2019s value that\u2019s been previously agreed on, which leaves enough room for change in between sprints.<\/p>\n\n\n\n
Kanban<\/h3>\n\n\n\n
An even less structured model<\/a> compared to Scrum, Kanban refers to the practice of limiting the amount of work in progress using a visual radiator that shows the status of each task. Unlike Scrum, Kanban doesn\u2019t imply iterations and is more often used for maintenance.<\/p>\n\n\n\nThe Big Bang Model<\/h2>\n\n\n\n
This methodology is exactly what it sounds like, i.e. no methodology at all. Its use is limited to tiny projects involving one to two developers, who are supposed to deal with requirements and change as they arise. While being helpful at reducing costs and complexity, it\u2019s unlikely to work for more serious projects.<\/p>\n\n\n\n
Which Methodology is Right for You?<\/h2>\n\n\n\n
Which SDLC model to choose depends on the goals you are pursuing, your budget, timeline, and resources. It\u2019s safe to say, however, that Agile methodologies are currently dominating the market, and for a good reason: they are flexible, lightweight, and easy to follow.<\/p>\n\n\n\n
