Proper management will help your team run projects of any complexity seamlessly. Software development methodologies (SDM) include the sets of techniques and approaches to organize an optimal project flow and bring your project management to a new level. However, before implementing any of the alternative software development models, you should understand the basic principles of each.
So, what are the different types of software development methodologies, and how to identify the right one for your task? The article covers a range of common SDMs, their pros and cons, and the guidelines for making the proper choice.
What is a software development methodology, and what does it include?
An SDM comprises several steps:
- Performance assessment.
The ultimate purpose of any SDM is to streamline the software development process. Generally, software development methodologies do not involve the technical aspects of software engineering. They target internal workflows and other operations related to the project.
What are alternative software development methodologies used today?
According to recent research, DevOps is the most pervasive method implemented by almost 47% of respondents in 2022. The reasons for choosing this approach include faster time to market, high code quality, and more efficient collaboration among developers.
To help you figure out which software development approach suits your organization best, we have collected a list of the most popular types of software development methodologies.
Much more than a mere methodology, DevOps also includes a range of practices supporting organizational culture. The approach focuses on enhancing collaboration among the departments responsible for various stages of the development process. Thus, the areas you need to cover include:
- Development phase,
- Internal operations,
- Quality assurance.
The method also implies consistency in task delegation between the teams involved.
This model denotes a disciplined software management process, giving room for frequent project changes. With this approach, developers design a conceptual framework instead of a rigid one. They develop software in iterations with the opportunity to add some new functionality at each.
Agile software development methodologies aim to counter risks, including the following:
- Excessive expenses,
- Unforeseen changes in software requirements.

Waterfall Development Methodology
This strategy implies a rigid linear framework consisting of sequential stages focusing on specific goals. The stages include
When applying this method, make sure that your team follows the major principles and fine-tunes every detail. Otherwise, it can be challenging to go back and revise the entire process.
The main difference between Agile and Waterfall software development methodologies lies in the working system. While Waterfall is a linear approach, Agile encourages the team to handle different phases simultaneously.
Scrum goes hand-by-hand with agile development as it focuses on implementing the agile approach. The scrum system utilizes various software projects to simplify the process.
The methodology comprises the following values:
- Transparency: maximum visibility into the organizational goals.
- Inspection: alignment of every process with the company requirements.
- Adaptation: immediate reaction to changing conditions.
Kanban accompanies an agile framework in its effort to enhance efficiency and collaboration. Although it lacks predefined roles, it enables greater flexibility in terms of task management.
Its general principles include
- Workflow visualization: the board displays every team member’s daily tasks.
- Workload optimization: it ensures that teams are dealing with only a few things at a time.
- Streamlining workflows: easy and smooth transition to the next steps once the previous tasks have been completed.
Lean Software Development Methodology
This methodology focuses on the improvement of quality and productivity. Here, the team determines the most appropriate solution through regular assessments to streamline the process.
The approach is based on the following pillars:
- Establish clear objectives to find the right solutions.
- Minimize wastage to enhance operational efficiency.
- Maintain consistency by continually analyzing performance.
- Exercise transparency by ensuring real-time data access.
Rapid Application Development
This methodology is a high-speed adaptation of the Waterfall model. However, in this case, you should build your process based on distinct variables.
- Requirements collecting
- User design
The team builds a platform based on the users’ responses to each activity. The primary goal of the method is to bring the best result in the quickest manner.

A checklist for selecting the optimal SDM
Once you have learned the different software development methodologies, it’s time to figure out how to select the one for your team. We have worked out a brief checklist to go through
- Ensure that the methodology meets your team’s and your client’s goals. Nevertheless, it should allow for certain adjustments throughout the process.
- Focus on your development environment rather than on the particular method. If your team lacks the necessary skills to implement DevOps methodology, you should better choose another approach.
- Consider the scope of your project. For smaller tasks, a throw-away approach may suit when you complete the development stage in a short term and perform re-evaluations over time. Larger projects can benefit from a feature-driven development that enables scalability and usability in the long term.
- Make sure your team understands the selected methodology and is properly prepared to apply it consistently.
- Remember to check if your existing environment is ready to support a tool or framework you’ve chosen to implement.
- Whatever methodology you select, it may sustain changes throughout the project development.
