Waterfall SDLC is one of the most primitive software development
life cycle management process, since its inception many other models like scrum, V shape model etc have evolved, but till this data if linear development needs to be undertaken then waterfall model is one of the best way to carry out software development.
Waterfall model is linear and sequential in nature, it doesn’t offer flexibility as compared to scum development cycle.
The waterfall model consist of the following stage:
->Requirement Analysis
The waterfall model consist of 6 PHASES, the requirement analysis and designing has to be done with precision because any changes ,rollbacks and amendments post requirement analysis stage can become highly complex and very expensive.
-> Designing Phase
-> Implementation Phase
-> Testing Phase
-> Deployment Phase
-> Maintenance Phase
Waterfall do involve lot of documentation, as each phase is associated with specific set of detailed documentation, documentation plays a critical role because without the right set of documentation, even if one Functional requirements needs to be changed then the whole waterfall SDLC will be effected resulting in higher cost and time implications.
The waterfall model can be highly effective based on project type, if it is small size and mid size project then the sequential nature of the waterfall model can be really beneficial due to high level of documentation and deep requirement analysis, But for big software projects which are dynamic in nature it is better to adapt to agile dev model/ scrum dev model.
