01

Waterfall Development

Waterfall methodology is the most traditional software development methodology. It is a linear and sequential approach that comprises six distinct phases: requirements, design, implementation, testing, deployment, and maintenance. Each phase must be entirely completed before moving to the next phase. This methodology is rigid and does not allow for changes once a phase is completed.

The benefits of waterfall methodology include its well-defined structure, making it easy to understand and manage. Additionally, it is suitable for projects with clear objectives and requirements. However, this methodology's disadvantages include the inability to accommodate changes and customer feedback, leading to increased project costs and time.

02

Agile Software Development

Agile is a flexible, iterative approach that emphasizes customer collaboration and continuous delivery. It is an umbrella term that encompasses different methodologies such as Scrum, Feature-Driven Development (FDD), and Rapid Application Development (RAD). Agile methodology values communication, feedback, and adaptability over rigid processes.

The benefits of the agile methodology include its flexibility, allowing for changes and customer feedback at any point in the development process. Additionally, it promotes collaboration among team members, leading to better project outcomes. However, the downside of agile methodology is that its flexibility may lead to scope creep, increasing project costs and time.

03

Scrum Development

Scrum is an agile methodology that emphasizes teamwork, accountability, and iterative progress. It comprises sprints, which are short development cycles that last between one and four weeks. Scrum methodology relies on three primary roles: product owner, Scrum master, and development team.

The benefits of Scrum methodology include its ability to accommodate changes and feedback, leading to better project outcomes. Additionally, it promotes teamwork and accountability, leading to better project outcomes. However, the downside of the Scrum methodology is that it may not be suitable for projects with unclear objectives and requirements.

04

Feature-Driven Development

FDD is an agile methodology that emphasizes the development of specific features or functionalities. It comprises five distinct phases: developing an overall model, building a feature list, planning by feature, designing by feature, and building by feature.

The benefits of FDD methodology include its ability to prioritize features based on customer needs, leading to better project outcomes. Additionally, it promotes collaboration among team members, leading to better project outcomes. However, the downside of the FDD methodology is that it may not be suitable for complex projects.

05

Rapid Application Development

RAD is an agile methodology that emphasizes rapid prototyping, iterative development, and close customer involvement. It comprises four distinct phases: requirements planning, user design, construction, and cutover. RAD methodology values speed and customer satisfaction over rigid processes and documentation.

The benefits of RAD methodology include its speed and customer satisfaction, leading to better project outcomes. Additionally, it promotes teamwork and flexibility, leading to better project outcomes. However, the downside of RAD methodology is that it may not be suitable for complex projects.
