Agile vs Scrum

Waterfall project management is a well-known method in software development, and its basic process is story -> development -> test. It is assumed that the final result is right, if each phase is done correctly. Microsoft uses the Waterfall method and it works well.

However, it has a relatively high failure rate, for the market and requirements are constantly changing. Software pioneers conducted a series of researches, thinkings, and summaries about the problems found in the Waterfall methodology and finally came up with the concept of Agile.

What is Agile?

Agile is an approach that helps one iterate on processes in the Software Development Life Cycle, such as development, testing, and so on. This technique has advantages, including the ability to produce high-value functionality in fast implementation times, which was previously a problem for the traditional waterfall approach. It also helps to enhance customer retention and satisfaction. This is accomplished by splitting down the product into smaller units/builds, allowing the operations to run concurrently. Agile encourages collaboration and face-to-face contact.

Agile Manifesto was release in 2001 by 17 independent-minded software practitioners.While the participants didn't often agree, they did find consensus around four core values.

Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan

Agile approaches include

• Scrum
• Kanban
• Feature Driven Development (FDD)
• Extreme Programming (XP)
• Lean Software Development (LSD)
• Adaptive System Development (ASD)
• Dynamic Systems Development Method (DSDM)
