A software development lifecycle model describes the types of activity performed at each stage in a software development project and how the activities relate logically and chronologically.
Types of Software Development Models
There are several software development lifecycle models, each of which requires different approaches to testing, and each has its advantages and disadvantages. Based on the project, an appropriate model is selected. A project’s quality, timeframes, budget, and ability to meet the stakeholders’ expectations largely depend on the chosen model. Here are some well-known Software Development Models or Methodologies:
- Waterfall Model
- V-Model (Verification and Validation Model)
- Iterative and Incremental Model
- Prototyping Model
- Rapid Application Development Model (RAD)
- Spiral Model
- The Rational Unified Process (RUP)
- Scrum
- Extreme Programming (XP)
- Kanban
- Lean Software Development (LSD)
- Test Driven Development (TDD)
Factors in Choosing Software Model
You have to consider several factors while choosing the Software model. Some of them are:
Nature of project
- Project size
- Project duration
- Project complexity
- Level and type of expected risk
- Level of understanding of user requirements
- Level of knowledge of the application area
- Customer Involvement
- Experience of developers
- Team Size
Phases of Software Development
Software Development Life Cycle describes the phases in the life cycle of software application development. Each model consists of the following Phases:
- Planning or Requirement Analysis
- Design
- Development or Implementation
- Testing
- Deployment
- Maintenance
Choosing the suitable SDLC model is one of the critical steps in delivering high-quality IT solutions for your organization. However, it is essential to understand that one solution may not work in all businesses or scenarios. But before selecting one, make sure to learn all about their pros and cons to discover the model that will fit your project best.
