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 Waterfall Emphasizes documentation and controlled processes as a measurement of success Emphasizes working software as the primary measure of progress 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 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 Progress is generally measured in terms of deliverable artifacts: requirement specifications, design documents, test plans, code reviews Progress is measured by the production of completely developed and tested features (but a very small subset of the whole) every few weeks Structured of the methods, stepping through requirements-capture, analysis, design, coding, and testing in a strict, pre-planned sequence Iterative and incremental development methods' emphasis on building releasable software in short time periods Waterfall Agile

Why Scrum Works

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.

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
