Jun 19, 2024 · The software development life cycle (SDLC) is a structured process that is used to design, develop, and test good-quality software. The SDLC life cycle model aims to deliver high-quality, maintainable software that meets the user’s requirements. In SDLC there are various models for software development models, waterfall model is one of them ...

Feb 8, 2024 · Software development is defined as the process of designing, creating, testing, and maintaining computer programs and applications. This diverse field combines creativity, engineering expertise, and problem-solving abilities to produce software that satisfies particular requirements and goals.

All SDLC models can be structured into several groups depending on how they approach workflow organization – linearly or iteratively – and what kind of relationships are established between the development team and the customer. The types in the lower quadrants of the chart take the sequential flow. They are easy to implement, use and manage. As yo...
Waterfall
Through all development stages (analysis, design, coding, testing, deployment), the process moves in a cascade mode. Each stage has concrete deliverables and is strictly documented. The next stage cannot start before the previous one is fully completed. Thus, for example, software requirements cannot be re-evaluated further in development. There is also no ability to see and try software until the last development stage is finished, which results in high project risks and unpredictable projec...
V-model
The V-model is another linear model with each stage having a corresponding testing activity. Such workflow organization implies exceptional quality control, but at the same time, it makes the V-model one of the most expensive and time-consuming models. Moreover, even though mistakes in requirements specifications, code and architecture errors can be detected early, changes during development are still expensive and difficult to implement. As in the Waterfall case, all requirements are gathere...
Incremental and Iterative model
The development process based on the Incremental modelis split into several iterations (“Lego-style” modular software design is required!). New software modules are added in each iteration with no or little change in earlier added modules. The development process can go either sequentially or in parallel. Parallel development adds to the speed of delivery, while many repeated cycles of sequential development can make the project long and costly. With Iterative developmentsoftware changes on e...
Using as basis the research data, we’ve compared the models in terms of core features – time, cost and quality – to make them easier to digest and comprehend. All estimates are relevant to small applications with code consisting of 1,000 functions.

- Waterfall. This sequential model is considered relatively easy to understand and manage due to its linear approach. Each phase has specific deliverables and a review process with detailed documentation of every stage, and each stage begins only after the previous one has been completed.
- Agile. Agile is highly flexible and adaptable to changes. It is not just one, but a bundle of models for agile development that reflect the 2001 Agile Manifesto.
- Spiral. Spiral software development model focuses on early identification and reduction of risks. Spiral is all about mitigating risk; it is its primary purpose.
- Kanban. Kanban is a derivative of Agile, focusing on visualization and work-in-progress limits. The Kanban software development model increases efficiency through visual management.
- Project requirements. Before you choose a model, take some time to go through the project requirements and clarify them alongside your organization’s or team’s expectations.
- Project size. Consider the size of the project you will be working on. Larger projects mean bigger teams, so you’ll need more extensive and elaborate project management plans.
- Project complexity. Complex projects may not have clear requirements. The requirements may change often, and the cost of delay is high. Ask yourself if the project requires constant monitoring or feedback from the client.
- Cost of delay. Is the project highly time-bound with a huge cost of delay, or are the timelines flexible?
Dec 21, 2022 · In general, software development models are the processes and methodologies selected for app development keeping in mind the goals and objectives of the project. These models define the flow in which a specific project needs to be carried out.
