A brief history of the agile methodology

View Original View Raw

Summary

Agile development is a common practice among tech organizations today, but it wasn't always the case. This article provides a brief history of agile development, from the heyday of the waterfall methodology to the birth of the Agile Manifesto in 2001. It outlines the differences between agile and waterfall practices and explains why agile is better suited for today's development environments, being based on flexibility, adaptability, collaboration, and continuous improvement. It also discusses the pros and cons of the waterfall methodology, how agile practices lead to better software, and the importance of agile development in the current digital era.

Q&As

What is the Agile Manifesto and how does it differ from the classic waterfall methodology?
The Agile Manifesto is a set of four major principles for agile project management, intended to guide teams on developing better software. It emphasizes collaboration over documentation, self-organization rather than rigid management practices, and the ability to manage constant change rather than being locked into a rigid waterfall development process. The waterfall methodology requires a lot of documentation up front, before any coding starts, and is based on the waterfall manufacturing method derived from Henry Ford’s 1913 assembly line innovations.

How did the waterfall methodology come about and why did it become its downfall?
The waterfall methodology was invented in 1970 and was revolutionary because it brought discipline to software development and ensured there was a clear spec to follow. It was based on the waterfall manufacturing method derived from Henry Ford’s 1913 assembly line innovations, which provided certainty about each step in the production process. The waterfall method was intended to ensure that the final product matched what was specified in the first place. However, its rigidity became its downfall as we entered the internet era, and speed and flexibility were more prized.

In what ways is agile methodology better suited to how developers and teams actually work?
Agile is designed for flexibility and adaptability. It does not require defining all the answers up front, as you do in the waterfall method. Instead, it breaks the problem into digestible components that are then developed and tested with users. Agile also encourages collaboration tools and agile development practices, which usually result in applications that are better quality and faster to develop.

Why is agile development better for creating digital experiences and how does it help enterprises attract and keep great talent?
Agile development helps enterprises deliver exceptional digital experiences in a hypercompetitive world, and it helps them attract and keep great talent to build great software. Agile prioritizes iterative development and leveraging feedback to improve the application and the development process, which is well suited to today’s world of operating smarter and faster. Agile also encourages ongoing improvement, which is necessary for software to stay up to date and relevant.

What are the principles of agile project management and how do they encourage ongoing improvement?
The four major principles of agile project management are: individuals and interactions over processes and tools; working software over comprehensive documentation; customer collaboration over contract negotiation; and responding to change over following a plan. These principles encourage ongoing improvement by allowing teams to adapt the effort quickly if something isn’t working as expected, and by allowing each team member to contribute to the solution and assume personal responsibility for their work.
