Software development life cycle models are used to define the processes to design and development of a software project. There are various types of software development life cycle that are used by in organization to develop a software project. Sometimes these all are called the standard models of software development life cycle. These all standard SDLC models follow some standardized format and/or series of steps to design and development a successful software product.
The selection of optimum model from the standard SDLC model based on the client project requirements. All these models have their own advantages and disadvantages, so on the behalf of these pros and cons of these models in industry software developer expertise suggest the best optimal way or model used to shoot the target project.
There are several standard software development life cycle (SDLC) models followed by various organizations. Here we are introduced to all these standard SDLC models in detail. The all of standard SDLC model follows by industry are listed below;
- SDLC Waterfall model
- SDLC Prototype model
- SDLC Iterative model
- SDLC Spiral model
- SDLC V model
- SDLC Incremental model
- SDLC RAD model
- SDLC Agile model
- SDLC Big Bang model
Selecting a right model from these available models of software developing or application development is very important. Based on the model selection the design, development and the testing processes are carried out.
Requirement of software development life cycle model:
Various software development companies and application development industries used these models of SDLC to design different software applications. Companies based on the requirement of software application or product select the type of developing SDLC model whichever suits to their application. Each model has their rules and principles those makes them unique to other and technique to handle the problem. Like “Waterfall Model” testing phase of developing software starts only after finishing the development phase. Due to that that cost of fixing these issues are very high. So the overall cost of developing software increasing when a company used waterfall model for developing software and then fixing issues in there. After waterfall model various upgrade models has come that overcome the deficiency of developing software processes in waterfall model. At present most of the companies using ‘Agile methodology’ to develop software application. This model has the functionality of after every sprint there is a demo feature available to the customer. Hence the customer can see the features whether they are satisfying their requirement or not.
In the industry and/or organization the project works are divided in to subdomains sometimes it is known as work destitution or sub modeling of the project. This way of sub modeling of the project is gives an expert solution to the shoot the project aims and provides a best solution to the customer as per requirement.
- Division of work in individual models
- Easy to planning and analysis
- Design a blue sketch of operation and functionalities
- Individual domain expertise work requirement.
- Calculating feasibility of the project.
