Improving the establishment of the Software Development Life Cycle (SDLC) process is dependent on a reliable method and a well-defined approach to ensure getting from point A to B. If you are starting to expand your background in the world of development, you need to have a full understanding of the SDLC.
SDLC types in action
The most notable SDLC models are cited as follows.
Waterfall. This is the oldest and most basic SDLC model. Using this SDLC methodology, one phase is completed then the next can be started. Every phase has its mini-plan and each “waterfalls” phase goes into the next. The largest model drawback is that small incomplete details can have an impact on the whole process.
Agile. This divides the product into cycles with faster working production. This SDLC methodology brings release succession. By testing every release provides feedback details that can be integrated into the succeeding version. Based on Robert Half, an American consulting company, the pitfall of this model is that too much emphasis on customer interaction can cause the project to be in the wrong direction in some instances.
Iterative. This model stresses the value of repetition. Software developers create an instant version at a relatively small cost. Then, they do validation and improvement through quick and successive versions. One main disadvantage is that it can consume resources quickly if left unattended.
V-shaped. This serves an extension of the waterfall model. This SDLC methodology evaluates every stage of software development. In the waterfall, this system can operate into roadblocks.
Big Bang. This is a high-risk SDLC model that puts most of its resources at the development and best to use for mini projects. It does not the thorough requirements definition stage present in the other methods.
Spiral. Among the SDLC types, this is considered the most flexible. This model is like the iterative model that stresses repetition. The spiral model undertakes the planning, design, build and test phases while at every pass gradual enhancements are undertaken.
Whenever the SDLC is accurately performed, this enables the highest documentation level of management control. Software developers know what they should create and why. Everyone accepts the upfront goal upfront and provides a better plan for achieving that goal. Everybody knows the required costs and resources.
Some pitfalls can lead an SDLC implementation as more of a challenge to development than a tool that helps us. When failures affect the clients, all users, and stakeholders, this can lead to poor system requirements at the outset. The SDLC co-exist if the plan is followed faithfully.
