Software development models
When building software, one of the first decisions you’ll need to make is which development model to use. Different software development models offer various levels of flexibility, structure and adaptability, depending on the project’s needs.

Let’s explore five popular software development models:
- Waterfall model
The Waterfall model is a linear, sequential approach where each phase (requirements, design, implementation, testing, deployment and maintenance) must be completed before moving to the next. It works well for projects with clear, well-defined requirements but lacks flexibility for changes. This model is best suited for projects with strict regulatory requirements or predictable outcomes.
- V-Model (Verification and validation model)
An extension of the Waterfall model, the V-Model integrates testing at each development stage. Every development phase has a corresponding testing phase, ensuring early defect detection. This model is suitable for projects requiring high reliability, such as healthcare or aerospace applications, where errors can have serious consequences.
- Iterative model
The Iterative model involves developing software in repeated cycles, allowing for incremental improvements with each iteration. It enables early software releases and refinements based on feedback, making it ideal for projects where requirements evolve over time. This model allows developers to identify potential issues early and adjust the design before full implementation.
- Agile model
The Agile model prioritises flexibility, collaboration and customer feedback. It divides work into small, manageable increments called sprints, enabling continuous improvement and rapid adaptation. Agile is best suited for dynamic projects requiring frequent updates and stakeholder involvement, ensuring that evolving business needs are consistently met.
- Scrum
Scrum is a specific Agile framework that emphasises teamwork, accountability and iterative progress. It uses time-boxed sprints, daily stand-ups, and defined roles such as Scrum Master and Product Owner. Scrum enhances productivity and adaptability, making it a popular choice for fast-paced software development teams.
Choosing from the software development models
Selecting the right software development model depends on project complexity, flexibility requirements, software goals and team dynamics. While Waterfall and V-Model suit structured projects, Agile and Scrum provide adaptability for evolving requirements. Iterative development offers a middle ground, balancing structure and flexibility.
