development life cycle (SDLC) is important for the software project success, the good software engineer should have experience and knowledge to prefer and choose one model than another based on the project context. To choose right SDLC model according to the specific concerns and requirements of the project you have to gain in-depth knowledge for which you can join Software Course.
In this post, we will explore the top software development methodologies-
The waterfall model is one of the most traditional and commonly used software development methodologies for software development. Waterfall model describes the software development method in a linear sequential flow which means that any stage in the development process begins only if the earlier phase is completed. This development approach does not define the process to go back to the previous phase to handle changes in requirements.
The benefit of applying this model is that because of the rigidity of the model it is simple to manage. Moreover, each phase has specific deliverables and individual review process.
It is an extension of the waterfall model, Instead of moving down in a linear way, the process steps are bent upwards after the implementation and coding phase, to form the typical V shape. The major difference between V-shaped model and waterfall model is the early test planning in the V-shaped model.
The benefit of using this model is that it has a higher chance of success over the waterfall model due to the development of test plans early on during the life cycle.
BIG BANG MODEL:-
This model does not follow any trend in software development and this is usually implemented when the client is not aware himself of what his requirements are or how they should shape up. This is a very simple model and no formal procedures are employed in the development process.
The advantage of using this model is that it requires few resources and gives adequate exposure to beginners looking to develop their skills.
It refers to the process of creating prototypes of software applications, for example, incomplete versions of the software program being developed. It used to visualize some component of the software to limit the gap of misunderstanding the customer requirements by the development team. This will also decrease the iterations may occur in waterfall approach and hard to be implemented due to the inflexibility of the waterfall approach.
Being a highly sophisticated design, it is meant to reduce the early risks in the project. According to the process going by, the developers start on a smaller level and explore the included risks in it. Further to this, the developers are intended towards crafting a plan for iterating of the spiral. The success of any Spiral Lifecycle model is based on observant, consistent, and conversant management of the project.
The advantage of using this model is that it is suitable for large and complex projects and highly risky projects with varied business needs.
AGILE SOFTWARE DEVELOPMENT METHODOLOGY:-
It is an approach that is used to design a disciplined software management process which also allows some frequent alteration in the development project. This is a type of software development methodologies which is one conceptual framework for undertaking various software engineering projects. It is used to minimize risk by developing software in short time boxes which are called iterations that generally last for one week to one month.
The benefit of this methodology is that direct communication and constant feedback from customer representative leave no space for any guesswork in the system.
RAPID APPLICATION DEVELOPMENT (RAD) :-
It is an effective methodology to provide much quicker development and higher-quality results than those achieved with the other software development methodologies. It is designed in such a way that, it easily takes the maximum advantages of the software development. The main objective of this methodology is to accelerate the entire software development process.
This methodology encourages customer feedback which always provides improvement scope for any software development project
