Software development methodologies are guidelines, principles, and practices software developers use to manage the software development life cycle. These methodologies help developers deliver software products efficiently, on time, and within budget.
This article will compare and contrast different software development methodologies, including Agile, Waterfall, and DASA, and highlight their pros and cons.
Agile Methodology
Agile methodology is an iterative and incremental approach to software development. It prioritizes customer satisfaction and collaboration between team members. The Agile methodology is flexible, adaptable, and focuses on delivering working software continuously. Some of the programming languages and technologies commonly used with Agile include:
Pros:
- Agile methodology is customer-oriented, prioritizing customer satisfaction over process compliance.
- The flexibility of Agile methodology allows teams to adapt to changes quickly.
- The Agile methodology encourages collaboration between team members.
Cons:
- The Agile methodology requires significant involvement from stakeholders and customers.
- The Agile methodology may not work well for large-scale projects requiring extensive documentation.
- If your organization prefers the Agile methodology and has large-scale projects, you could consider leveraging SAFe (Scaled Agile) which is specifically designed to adapt Agile at a larger scale.
Waterfall Methodology
Waterfall methodology is a sequential, linear software development approach involving a predefined set of stages. Each stage is completed before the next one begins. The Waterfall methodology is rigid, inflexible, and requires extensive documentation. Some of the programming languages and technologies commonly used with Waterfall include:
- C / C++
- IBM Automation
- IBM Business Process Manager
- IBM CICS
- IBM Cobol
- IBM Db2
- IBM IMS
- IBM ELM
- IBM WebSphere
- IBM z/OS
Pros:
- The Waterfall methodology is well-suited for large-scale projects with extensive documentation requirements.
- The Waterfall methodology ensures that each stage is completed before moving to the next stage.
Cons:
- The Waterfall methodology is rigid and inflexible, which makes it challenging to adapt to changes.
- The Waterfall methodology does not prioritize customer satisfaction.
DASA Methodology
DASA stands for DevOps Agile Skills Association. It leverages a methodology that combines Agile and ITIL. The DASA methodology prioritizes automation, continuous improvement, and collaboration between teams. Some of the programming languages and technologies commonly used with DASA include:
Pros:
- The DASA methodology combines Agile and ITIL, which makes it well-suited for DevOps teams.
- The DASA methodology prioritizes automation and continuous improvement.
Cons:
- The DASA methodology may not be suitable for organizations that do not follow the ITIL framework.
