Waterfall Model

The waterfall model is one of the most classic and sequential software development methodologies that simplifies the development process by following a sequential and structured approach. In this methodology, developers will only move to the second stage after completing the first stage in its entirety. It follows a rigid linear method where the development phases are placed in a cascading manner. The development process flow in this methodology is just like how the waterfall flows, going in a single direction and not backward.

Compared to the agile methodology, the waterfall software development methodology is less adaptive and flexible to changing requirements. This methodology is perfect for businesses that are dealing with projects that demand a high-planned and controlled development process. The waterfall model is easy to understand and simple to manage, as the next phase will process based on the information received from the previous stage. For smaller projects or software development with few or no changing requirements can adapt the waterfall development methodology.

Six Stages in Waterfall Methodology

  • Requirements: This is the initial planning stage, where the team gathers all the necessary information and determines the project scope, objectives, and process for each development phase. By the end of this stage, decision-makers will have a concise project development outline, including required resources, project functions, each stage of the process, key dependencies, and timeline.
  • System Design: The next stage in the waterfall model is system design. In this phase, the team decides the best suitable software architecture along with other information like the programming language to be used, user interface design, etc. Also, the team will document everything to use as a reference in the next stages.
  • Implementation: Following the project requirements, the team initiates the development process according to the defined outline and architecture in the requirement and system design stage.
  • Testing:  The development team will hand the project over to the quality assurance team to check for any bugs or errors. So the developed software will have no flaws at the time of deployment.
  • Deployment: After the testing phase, the software is deployed to the end-user or client in this stage. The team moves forward with software deployment only after ensuring the project meets the client's requirements.
  • Maintenance: Once the project is delivered to the client and the client requires fixing new bugs or issues and updating the software, the maintenance stage comes into the picture. This stage is common in software development, and the team continues to work on this phase as per the requirement.

But a side-by-side comparison of some popular development approaches can help you clear the clouds of confusion. Here we will compare some methodologies, including Agile vs Waterfall, Agile vs Lean, Lean vs Scrum, and Spiral vs Prototype Model.

Agile vs Waterfall

The comparison of Agile and Waterfall, the two most contrasting approaches in software development, will help you get broadly differentiate them. The Waterfall methodology follows a linear and sequential approach, which is ideal for well-defined projects with stable requirements. Although the Waterfall model offers predictability but is less adaptive to changing requirements and lacks customer involvement. On the other hand, the Agile methodology has an iterative and flexible approach to software development. With the Agile software development methodology, you can deal with dynamic projects by easily adapting to evolving customer requirements. Agile facilitates shorter development cycles, continuous user feedback, and team collaboration.

Aspect Agile Waterfall
Approach Iterative, incremental Linear and sequential
Flexibility Highly flexible Rigid
Process Divided into small iterations or sprints The process breaks down into several phases
Collaboration Highly collaborative Less collaborative
Customer Involvement High Limited
Testing Performed in the same iteration  Performed in a separate phase
Changes Embrace changes at any development stage Changes are discouraged once the development begins
Time-to-Market Performed in the same iteration Longer due to sequential cycles
Suitable Projects Dynamic projects with evolving requirements Performed in a separate phaseOnly well-defined projects with stable requirements
Customer Satisfaction High due to frequent involvement and feedback Customer involvement is not required

Agile vs Lean

Both Agile and Lean software development methodologies offer efficient software development. Agile, as you know, follows an interactive development while emphasizing customer collaboration and faster development. While the Lean methodology prioritizes efficient development processes and waste reduction. Select the best software development methodology based on your project requirements and desired results.

Process Streamlining Moderate Significantly focus on streamlining processes
Ease of use Easier to use for dynamic requirements Does not embrace dynamic changes in deliverables
Risk Management Continuous risk assessment Helps to prevent risks during the process
Suitable Projects Small and large projects with changing requirements Suitable for small and startup projects

Lean vs Scrum

Comparing these two software development methodologies, Lean and Scrum, both share a commitment to efficient development but differ in terms of user collaboration. The lean methodology aims to deliver the maximum value to the customer by streamlining processes and eliminating waste and inefficiencies. In contrast, the Scrum model focuses more on team and customer collaboration with consistent user feedback for product quality improvement.

Aspect Lean Scrum
Goal Eliminating waste and inefficiency in the process Building user-centric products based on consistent user feedback
Iterations Continuous improvements Sprint-based approach (1-4 weeks per sprint)
Outcome Improving and optimizing processes and reducing costs Incremental value delivery and reducing redundant steps
Implementation Widely throughout the organization  Often implemented among different teams
Roles and Responsibilities Flexible roles Defined roles and responsibilities
Collaboration Promoted collaboration Emphasizes teamwork and collaboration
Transparency Less focus on transparency Highly transparent through scrum meetings
Applied To Existing recurrent processes New feature development
Suitable Projects Small and large projects with changing requirements Suitable for small and startup projects

Spiral vs Prototype Model

The Spiral methodology, as we have mentioned earlier, is a risk-driven iterative approach that puts a strong emphasis on risk management and mitigation. While the prototype development methodology creates prototype models to demonstrate to the end users and gather feedback As both development methodologies involve users effectively, you can select the best matchable approach that aligns with your project goals and complexities.

Aspect Spiral Prototype
Focus Risk assessment and mitigation User involvement and validation
User Collaboration Moderate High
Planning Structured planning Limited planning
Product Improvement Cost Improvement in product quality increases the overall cost Improvement in product quality does not impact the cost
Requirements Validation Continuous validation Early validation
Project Understanding Does not need clear and defined client requirements The client and project requirements should be priorly well-defined
Suitable Projects Suitable for complex, evolving requirements Suitable for projects with evolving requirements

Factors To Consider When Choosing The Right Software Development Methodology

We are certain that with several software development methodologies enlisted above, choosing the correct one will be a bit challenging. Each development model has its own perks, disadvantages, and applications that are crucial to take into consideration. That’s why we have covered here some essential factors that will help you select the most appropriate software development methodology to lead your project to success.

Project Scope

Having a clear and concise understanding of the project scope and requirements can help you select the best development approach. Different methodologies work well with different project needs. For example, Agile is best suited for projects with variable and undefined requirements, while you can choose the waterfall model to implement a more structured and sequential approach for a large-scale project.

Development Team

The second factor you need to consider while picking the right software development methodology is development team dynamics. You need to take into consideration the size, location, skillset, and experience of your development team. For some methodologies like Agile, RAD, and FDD, the success of the project relies on how skilled and experienced the development team is.

Flexibility and Adaptability

For projects with continuously evolving or changing requirements, it will be beneficial for business owners to choose a development methodology that provides flexibility and adaptability. You can choose Agile, DevOps, Scrum, or Spiral software development methodology that allows you to work on projects that need a high degree of flexibility and adaptability.

Define End Customers

Defining end customers and understanding their expectations and requirements should be one of the most important aspects for businesses indulged in the software development industry. Before initiating software development, it is important to know whether the client has fixed requirements or if they vary a lot. For fixed project scope, you can select an iterative development approach, while you can opt for a collaborative approach for clients with fluctuating needs.

Project Size

The project size and complexity can play a crucial role when determining the suitable methodology. It will be better to choose the Agile or DSDM model if you are dealing with a large project that may engage several resources. However, you can select the waterfall methodology if the project can be efficiently completed by allocating fewer resources in the development process.


The budget can also be a viable aspect to take into consideration as it can impact the software development methodology selection. If you are opting for the Spiral methodology, you need to be prepared for its high expense due to multiple spiral phases and longer development cycles. However, if a project involves budget restraints, the Lean software development model can be a suitable option.

Risks and Uncertainties

Determining the uncertainties and risks associated with the project requirements can impact the overall success rate. Software development methodologies like Agile and Spiral are best suitable for projects that require high uncertainties and risk management. These approaches offer flexibility to carry out adjustments during the project development journey.

Time Constraints

Some methodologies can offer faster development, while others may offer slower development cycles. So it is essential to consider time constraints while determining the best suitable software development methodology. You can select the Agile or RAD methodology for rapid iterations and faster development, while you can select the Waterfall approach for linear, sequential development.


Hopefully, you will find the above-listed methodologies in software development helpful to cater to varying project requirements, team dynamics, and customer expectations.
