Study Notes

What is Agile Methodology?

Agile methodology promotes continuous iteration of development and testing throughout the software development lifecycle.
Agile is the ability to create and respond to change in an uncertain and turbulent environment.

Agile Software Development

Agile software development is an umbrella term for a set of frameworks and practices based on the values and principles expressed in the Manifesto for Agile Software Development and the 12 Principles behind it.
Agile software development focuses on the people doing the work and how they work together.
Solutions evolve through collaboration between self-organizing cross-functional teams utilizing the appropriate practices for their context.

Agile Manifesto

The Agile Manifesto was written in 2001 by 17 independent-minded software practitioners.
The Agile Man

ifesto values:

Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan12 Principles of Agile
Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.
Welcome changing requirements, even late in development.
Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale.
Business people and developers must work together daily throughout the project.
... Comprehensive documentation is crucial in Agile methodology, ensuring seamless collaboration between customers and development teams. Emphasizing customer satisfaction, comprehensive documentation dictates that the highest priority is to satisfy the customer through early and continuous delivery of valuable software. Effective communication is vital in Agile, featuring principles such as customer collaboration over contract negotiation.

The Agile philosophy welcomes changing requirements, even late in development, fostering adaptability. Iterative development enables deliverance of working software frequently, often within a couple of weeks to a couple of months, with a preference for the shorter timescale. Agile methodology emphasizes cohesiveness between business people and developers, requiring daily collaboration throughout the project.

Significant departures from traditional methods like Waterfall manifest in Agile's response to change.

Agile vs Waterfall Method

Agile is more flexible and accounts for experimenting with different directions.
Waterfall has a fixed timeline and does not involve the client or project owner during the process.

Key Differences between Agile and Waterfall

Timeline: Agile has a flexible timeline, while Waterfall has a fixed timeline.
Involvement: Agile involves the client or project owner throughout the project, while Waterfall does not.
Flexibility: Agile is more flexible and welcomes changes, while Waterfall is less flexible and has a fixed approach.
