Aug 11, 2019 · We clearly explain 8 key models of software development life cycle, compare them on 2x2 quadrant, show how they are performing, and explore popular use cases.

A key observation is that model management is a central activity in software design. Rather than seeking to build a single consistent model, software designers need to reason about the inconsistencies and dependencies between a set of inter-related partial models.
- 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?
Jan 30, 2023 · In this post, we will examine a number of questions related to the reasons for creating models, the selection of types of models, modeling languages, and model-evaluation criteria. The requirements enforced at any given moment have, in many cases, evolved and diverged from earlier requirements statements.
- Waterfall Model. Waterfall model is a famous and good version of SDLC(System Development Life Cycle) for software engineering. The waterfall model is a linear and sequential model, which means that a development phase cannot begin until the previous phase is completed.
- V-Model. V-Model is an SDLC model, it is also called Verification and Validation Model. V-Model is widely used in the software development process, and it is considered a disciplined model.
- Incremental Model. In Incremental Model, the software development process is divided into several increments and the same phases are followed in each increment.
- RAD Model. RAD model stands for rapid application development model. The methodology of RAD model is similar to that of incremental or waterfall model.
Sep 5, 2023 · Software process models facilitate robust quality assurance and risk management practices. These models ensure that software is thoroughly tested before deployment by defining specific checkpoints and validation processes.

A software process model is an abstract representation of a process that presents a description of a process from some particular perspective. There are many different software processes but all involve: Specification – defining what the system should do;
