The 9 Most Popular Software Development Models 2025

The software development industry uses dozens of models that cater to niche demands or meet the general requirements of broad-use applications.

Here are 9 of the most popular software development models commonly used to build applications for businesses today:

9. Rational Unified Process (RUP) Model

The Rational Unified Process model is a framework through which the software development workflow is managed through consecutive revisions.

Designed for object-oriented models, a rational unified process (RUP) uses the Unified Modeling Language for design and documentation.

Five phases, Inception, Elaboration, Construction, Transition, and Production, form the structure of RUP models and allow for iterative development.

RUP models deliver customizable development throughout the project by taking a modular approach.

Advantages

• The RUP model emphasizes robust documentation throughout the project’s lifecycle for optimal transparency.
• Risk analysis and management are embedded in the process to minimize critical obstacles.
• The model has extensive online support and tutorials to help with implementation.

Disadvantages

• Rational unified process models are complex, requiring a team of professionals to implement.
• The process-heavy nature of the RUP model makes it unsuitable for small projects.

When To Use

With its component-based architecture and structured approach, the RUP model is ideal for larger, complex projects requiring iterative development.

Smaller, more manageable cycles allow developers to adapt to new requirements quickly throughout a project’s duration.

8. Iterative & Incremental Model

As the name implies, the iterative and incremental models combine two complementary approaches to software development to improve project management.

A close relative of the Agile model, it blends the manageable components of an incremental model with the cyclical iterative model common in software development.

This approach ensures the cost of software development is focused on maximizing efficiency throughout all stages while making necessary improvements.

Advantages

• By taking small steps from the outset, projects can be changed as and when required without necessitating a significant overhaul of processes.
• Blending the two models confers both benefits, from the incremental model’s cost-effectiveness to the iterative model’s adaptability.
• The stage-based approach to development speeds up delivery, allowing for early releases to be shared with stakeholders and beta testers.

Disadvantages

• This development model can require extensive resources and rigorous project management to offer a high degree of flexibility.
• Progress tracking and identifying issues is more complex, with overlapping development priorities to consider.

When To Use

Projects that begin as basic applications and can be incrementally expanded over time are ideally suited to this model.

The model also works well for projects that demand ongoing feedback from stakeholders and clients throughout development.

7. Prototype Model

The prototype model, which fits within a broader development life cycle, is a more simplified model often used in the software development process.

A prototype is a scaled-down version of the intended final product that serves as a preliminary design for clients and other stakeholders to experiment with.

The prototype model, typically not released to the broader user base, allows developers and clients to explore ideas that help the project evolve.

Advantages

• Through a flexible design approach, clients can clearly understand how the final product should work.
• Identify any bugs, errors, or missing functionality early in the development process to address them quickly.
• Provide a reusable model that can be applied to similar software development projects in the future.

Disadvantages

• The prototype model can be costly, particularly if the developed prototype isn’t reused.
• Potential for scope creep and expansion of features that go well beyond what should be sufficient for a prototype.

When To Use

The prototype model is best used within the context of a larger project to demonstrate core features in the early stages of development.

Once it has been used to demonstrate feasibility and gather feedback, the development process can focus on the core product.

6. Rapid Application Development Model

The Rapid Application Development model is another self-explanatory approach to development that shares many qualities with the prototype model.

Avoiding heavy planning and preparation, the model allows for quick development and deployment with a user-focused approach.

Sometimes applied to custom software development for startups, it’s a flexible and scalable approach with a potential short turnaround time.

Advantages

• RAD is an ongoing and transparent development process that helps to build confidence with stakeholders and investors.
• Combining the best elements of the prototyping and iterative model ensures faster time-to-market than other SDLC models.
• Ongoing feedback reduces the potential for missed errors and expensive debugging later in the project’s lifecycle.

Disadvantages

• Without robust communication protocols, rapid application development-based projects can veer off track due to a lack of coordination.
• Successful application of the model requires all parties to be on the same page to avoid overrunning.

When To Use

If you’re launching a project with a tight deadline, the rapid application development model is ideally suited to deliver a fast turnaround.

That said, ensuring the development team has the relevant experience is vital to prevent issues from arising that may hinder the project’s success.

5. Spiral Model

Another frequently used software development model is the Spiral model, which combines elements of the Waterfall model and iterative model.

Taking its name from the spiral diagrammatic approach, it begins with defining priorities and performing a risk assessment before moving to engineering.

After evaluation and further planning, the next iteration of the spiral model is initiated, with the process repeating until completion.

Advantages

• This development model is oriented toward risk management across larger projects throughout the process.
• By incorporating regular reviews, developers and clients can remain on the same page and ensure customer satisfaction.
• Large and complex projects without clearly defined features can incorporate new elements at short notice without compromising overall quality.

Disadvantages

• Implementing and managing the spiral model can be complicated, requiring highly experienced engineers to handle risk assessment and compliance.
• Implementing clear milestones can be tricky, with many unknown variables that may arise throughout the project’s lifecycle.

When To Use

Large-scale projects with relatively open-ended requirements that need to adapt frequently often adopt the Spiral model.

The model is particularly relevant for applications involving sensitive data, where robust, ongoing risk management is vital for success.

4. V-Model

The V-model approach aligns development and testing processes by taking its name after the shape of its diagrammatical representation.

This strategy enables a continuous testing phase alongside the coding phase, from design and analysis to coding and unit testing.

The V-model is suitable for various types of software development. It is designed for transparency and facilitates clear communication in large teams.

Advantages

• The V-model, with its rigorous test-driven development, helps ensure the highest quality of the end product.
• Encouraging collaboration and efficiency is at the heart of the V-model, connecting different team members with relevant stakeholders.
• Comprehensive documentation ensures the development process is clearly understood, with easy code maintenance.

Disadvantages

• While the V-model is robust for many projects, its comparative lack of flexibility makes it unsuitable for projects requiring rapid changes.
• The thorough documentation process can make the model time-consuming, particularly for projects with a short turnaround time.

When To Use

The V-model, with its built-in enhanced testing processes and detailed documentation, is best suited for intricate projects that must meet high standards.

It’s also a good option for clients who expect to work closely with the development team through all project stages.

3. DevOps Model

One of the more recent software development models is DevOps, which represents a combination of development and operations.

This streamlined approach, related to the Agile model, provides a cross-functional platform that blends frequent software releases with fast development.

Many of the best-known custom software examples incorporate DevOps, with DevSecOps also utilized when robust security measures are essential.

Advantages

• DevOps employs a cutting-edge approach to the development phase, utilizing AI tools to support business transformation.

2. Waterfall Model

The Waterfall software development model is a more simplistic approach favored by developers working on projects with clear goals.

This model takes a linear approach, addressing each phase in sequence, completing one before proceeding to the next.

These phases include analysis, design, construction, testing, deployment, and maintenance, making this model one of the earliest used by developers.

Advantages

• The waterfall model’s clear structure makes it easy to stay on track and follow rigid milestones.
• Transparent goals reduce the risk of confusion by working toward implementing pre-determined software requirements.

Disadvantages

• Adapting to change is difficult with the Waterfall model, as its linear approach leaves little room for adjustment on the fly.

When To Use

Organizations with clear and typically simple application requirements can use the Waterfall model to develop their software.

Its highly methodical approach ensures a transparent structure and helps the team focus on the features that matter to the end user.

1. Agile Model

Perhaps the most commonly used development approach is the Agile model, which has been more broadly adopted in project management.

The agile methodology allows clients and the development team to create a flexible software development plan that directs resources where needed.

In addition to thorough requirement gathering and design, the Agile model also provides comprehensive testing and continuous feedback.

Advantages

• With its incremental approach and frequent feedback, Agile allows for highly functional results from the early stages of development.
• Characterized by efficiency and communication, it’s also capable of reducing the cost and duration of a project.

Disadvantages

• A lack of clarity from stakeholders in the planning stages can derail the project and create confusion among developers.
