What is Agile

Founded as a methodologies for software development, Agile is an iterative development process built around self-organizing teams.

Agile Methodologies

• SCRUM

• Crystal Clear

• Extreme Programming

• Adaptive Software Development

• Feature Driven Development

• Dynamic Systems Development Method

Agile Basics

Emphasis on obtaining the smallest workable piece of functionality to deliver business value early and continually improving and adding more functionality throughout the life of the project.

Agile vs WaterfallAgile Waterfall

Iterative and incremental development methods' emphasis on building releasable software in short time periods

Structured of the methods, stepping through requirements-capture, analysis, design, coding, and testing in a strict, pre-planned sequence

Progress is measured by the production of completely developed and tested features (but a very small subset of the whole) every few weeks

Progress is generally measured in terms of deliverable artifacts: requirement specifications, design documents, test plans, code reviews

Breaks tasks into small increments with minimal planning, and do not directly involve long-term planning which makes it easier to adapt to changes in requirements

Ill equipped to adapt to change because it tends to fall apart when the problem being measured is constantly changing due to requirement modifications and new realizations about the problem itself

Emphasizes working software as the primary measure of progress

Emphasizes documentation and controlled processes as a measurement of success

• Scrum revolves around the ethos of simplicity, resulting in delivery of something that moves the project forward:• What have you done during the last 24 hours?• What do you plan to do in the next 24 hours?• What’s stopping you getting on with the work of the

next 24 hours?

• This is useful because:• This is progress, it’s work completed to date• This is forward planning, it is work you are about to do• These are your impediments or obstructions, it might

be things you need in order to work…more forward planning. It’s also identification of immediate risks.

Why Scrum & Agile Work for Web Development

• Collaboration across interdisciplinary team• Direct involvement of product owner

(stakeholders)• Flexibility to prioritize features based on

budget and time constraints• Adaptable to changing requirements and

evolving solutions to problems• Forward-moving iterative process
