What Is Software Development Methodology?
Software development methodologies refers to structured processes applied in project work. It combines design principles and pragmatic reality rooted in the early days of computing.
Over the years, various Software development methodologies have been established. They aim to leverage evolving technologies and resources. These methodologies provide a foundation for developers.
They can collaborate more efficiently as a team. They formalize communication and define how information is shared within the team.
However, the debate persists about which method is superior. The development is that there is no one-size-fits-all solution.
Each methodology comes with its own advantages and disadvantages. Success depends on team structure, project requirements, and goals. It’s not uncommon to use different methods for various projects.
Why follow the software development methodologies?
It’s essential to understand the need for choosing and following a software development methodology throughout a project.
Taking this process for granted introduces numerous risks. It exposes developers to ever-changing customer requests and potential miscommunications.
Without structured guidance, revisions to the software may become frequent. Often, they don’t consider the overall project implications.
This can waste time, money, and effort. It can produce a subpar application that falls short of expectations.
Development teams and customers both benefit from the design of software development methodologies.
Ensuring that discussions are conducted through proper channels involves choosing the correct method. It also provides that we make decisions after thoroughly evaluating all relevant factors.
Using a software development methodologies helps teams minimize inefficiencies. It also helps them provide more accurate delivery timelines.
Let’s discuss software development methodology one by one in detail.
Waterfall Model
The Waterfall Model is a popular method of developing software. It can be compared to building a structure with Lego bricks. It involves progressing through distinct steps or phases. It’s similar to assembling one piece of the Lego set before moving on to the next.
This process unfolds linearly and sequentially. It’s much like a waterfall cascading down levels. Each phase in the Waterfall Model is like a building block. It must be completed thoroughly before advancing to the next one.
This approach ensures a systematic and disciplined way of handling software development. It helps to provide a clear road map for the project. Developers follow a rigid structure. They emphasize the importance of completing each phase before proceeding further.
This simplicity and orderliness contribute to the reliability and predictability of the Waterfall Model. This makes it a foundational methodology in software development.
Sequential Phases
The Evolution of PHP and Why it is Still Relevant?
2. Design: The design phase involves creating detailed plans, architecture, and system specifications based on the gathered requirements.
3. Implementation: Developers execute the design plans, translate them into actual code, and build the software system.
4. Testing: The software undergoes rigorous testing to identify and rectify defects, ensuring it meets the specified requirements.
5. Deployment: Once successfully tested, the software is deployed and delivered to the end-users.
Advantage and disadvantage
Use Cases

Agile Methodology
Agile is a dynamic software development method. It emphasizes flexibility and collaboration to enhance adaptability and customer satisfaction.
It prioritizes individual contributions, effective communication, and practical solutions. It values customer involvement and responsiveness to change over strict processes and tools.
You will also gain the knowledge to make informed decisions. This will help you select the best software development methodology that aligns with your team and project.
In Agile, we divide projects into small, manageable parts called iterations. These iterations follow an iterative and incremental development approach.
People do work in repeated cycles. Each cycle builds on the previous one. At the end of each iteration, we deliver a potentially usable part of the product.
This enables continuous feedback and refinement. This iterative process allows ongoing improvements and adjustments based on real-time insights. It ensures that the final product aligns closely with customer needs and expectations.
Scrum, Kanban, and Extreme Programming (XP) within Agile:

Advantage and disadvantage
Spiral Model
The Spiral Model is a software development approach that blends features from both the waterfall and prototyping methodologies.
It emphasizes iteration and risk analysis. This model guides the development process through a series of iterative cycles. Each cycle represents a phase in the project’s evolution.
The primary key feature of the Spiral Model is its focus on risk management. It encourages developers to assess and address potential risks at every stage.
This ensures that issues are identified and mitigated early in the development process. This iterative approach allows for flexibility and adaptation as the project progresses.
The model involves four main phases: determination of objectives, risk assessment, and mitigation. It also includes development and testing, and an evaluation of the current iteration.
This continuous spiral-like cycle repeats until the final product is ready. The Spiral Model is especially good for large, complex projects. When managing uncertainty and risks throughout the project’s development, we use it.
Iterative Development with Risk Analysis
1. Iterative Development: The Spiral Model follows a cyclical approach where the project evolves through repeated iterations, allowing for the incorporation of new features and improvements.
2. Risk Analysis: Each spiral iteration includes a risk analysis phase, where potential risks are identified, assessed, and strategies are developed to manage or mitigate these risks.
Phases in Spiral Model
1. Planning: Define the project objectives, risks, and constraints.
2. Risk Analysis: Evaluate potential risks and develop strategies to address them.
3. Engineering: Develop, test, and integrate the product based on the planning and risk analysis.
4. Evaluation: Review the results of each iteration to decide whether to proceed to the next spiral.
Advantage and disadvantage
Applicability and Comparison with Other Models
1. Applicability: Suitable for large, complex projects with changing requirements and a need for frequent risk assessment.
2. Comparison: Contrasted with the waterfall model, the Spiral Model accommodates changes more flexibly. It also provides a systematic approach similar to the waterfall model.
Feature-Driven Development (FDD)
1. Domain Object Modeling: FDD places significant importance on creating a clear and comprehensive model of the problem domain. This involves identifying and modelling the key elements (objects) in the system’s domain and their relationships. This model serves as a foundation for understanding and designing the features.
Feature-Driven Development (FDD) is a methodical and iterative approach to software development that revolves around constructing features as its central focus. This methodology incorporates several key concepts to guide its process:
2. Developing by Feature: FDD organizes development around individual features, which are distinct functionalities or capabilities that provide value to the end-users. Teams work on these features in a structured manner, breaking down the overall project into manageable, incremental pieces.
3. Individual Class Ownership: FDD encourages a sense of ownership and responsibility among developers. Each class in the system is assigned to a specific developer who becomes the primary owner of that class. This ownership model enhances accountability and promotes efficient collaboration.
4. Iterative and Incremental Development: FDD follows an iterative and incremental approach where features are developed in short iterations. A potentially shippable product increment is produced at each iteration.
Roles and Responsibilities
1. Chief Architect: Responsible for overall design and architecture.
2. Class Owners: Developers responsible for specific classes or features.
3. Domain Experts: Provide insights into the application domain.
4. Chief Programmer: Oversees the development team and ensures quality.
Advantage and disadvantage
