When it comes to software development life cycle there are different types of software development life cycle which means that there are different ways to go about modifying, creating or altering software and technology and people play an important role in the process. There are various types of software development life cycle and before employing any of these companies first take into account which of the various software development life cycle models would help them achieve their goals.
Of the many types of software development life cycle, the waterfall model is one of the more known models. In the waterfall model companies tend to go from one stage to the next after the previous step is complete. So, one would first go through analysis of the software and right after the analysis is complete they would go on to software design. Once the design is successfully worked upon, integration and implementation of the software design is the next idea. What happens this way is that one goes on to the next step knowing that the previous step was successful. Sometimes reviews may be carried out or conducted before moving on to the next step to ensure that the last step was truly successfully carried out.
Another of the various types of software development life cycle is the spiral model and the main purpose of this model is to ensure that any risk is managed well first. Rapid prototyping methodologies were combined with the waterfall model in order to come up with the spiral model. This model consists of quadrants which are consistent of the formulation of plans so that the software targets could successfully be implemented and the restrictions of the project development are clarified. The next step is risk analysis which is a step that is even taken in other types of software development life cycle to ensure that any risks are eliminated and dealt with prior to the implementation of the project. This is usually the task of software developers who have the knowledge and expertise required to analyze the software and ensure that the spiral model would work successfully.
Then there is the agile approach. Of the various types of software development cycle mentioned here, this software is the more modern one. It has a people-centric approach which means feedback is considered to be important. This feedback would give an idea of how to improve the software and make it more efficient for users. The phases of the previous types of software development life cycle models are further broken down to make the process more efficient, better and it does not take more than a few days or short weeks to implement and succeed with these types of software development life cycle either unlike the previous types of software development life cycle which take much longer.
Though there are other types of software development life cycle these 3 are quite popular amongst software developers because they are easy to understand. It may take time to complete the steps though.
