sdlc methodologies list

waterfall is the oldest and most straightforward of the structured sdlc methodologies — finish one phase, then move on to the next. each stage relies on information from the previous stage and has its own project plan. waterfall is easy to understand and simple to manage. this model doesn’t work well if flexibility is needed or if the project is long term and ongoing. also known as the verification and validation model, the v-shaped model grew out of waterfall and is characterized by a corresponding testing phase for each development stage. the iterative model is repetition incarnate. a new version of the software is produced with each phase, or iteration. one advantage over other sdlc methodologies: this model gives you a working version early in the process and makes it less expensive to implement changes.

this model allows for the building of a highly customized product, and user feedback can be incorporated from early on in the project. but the risk you run is creating a never-ending spiral for a project that goes on and on. this is one of the sdlc methodologies typically used for small projects with only one or two software engineers. by breaking the product into cycles, the agile model quickly delivers a working product and is considered a very realistic development approach. at each iteration, the product is tested. but since this model depends heavily on customer interaction, the project can head the wrong way if the customer is not clear on the direction he or she wants to go. each of these sdlc methodologies offers unique process for the variety of project challenges you will encounter in your career. discover the myths around end of year recruitment and find out why now is a great time to start updating… forget the december shutdown – the last month of the year is actually one of the best times to ramp up your search for talent.

think of it as the equivalent to the scientific method for software development and other it initiatives. the waterfall approach is one of the oldest sdlc models, but it has fallen out of favor in recent years. as its name suggests, the premise of devops is to bring development teams together with operational teams in order to streamline delivery and support. a blend of the iterative and waterfall approaches, the challenge with the spiral model is knowing when is the right moment to move onto the next phase.

the agile methodology is the opposite of the waterfall approach. in the prototyping methodology, the design team’s focus is to produce an early model of the new system, software, or application. certain projects may run best with a waterfall approach, while others would benefit from the flexibility in the agile or iterative models. with offices located just minutes away from atlanta in duluth, georgia and washington d.c., innovative architects is a gold certified microsoft partner and expert it consulting firm offering comprehensive microsoft consulting services for georgia, alabama, florida, tennessee, north carolina, south carolina, mississippi and new york.
