WHAT IS SCRUM?

Scrum is an iterative and incremental agile software development methodology for managing product development. It defines "a flexible, holistic product development strategy where a development team works as a unit to reach a common goal", challenges assumptions of the "traditional, sequential approach" to product development, and enables teams to self-organize by encouraging physical co-location or close online collaboration of all team members, as well as daily face-to-face communication among all team members and disciplines in the project.

- Please don’t go there. There are obstacles waiting.

- But, why? I won’t let them waiting.

Sprint Backlog

Product Backlog

Potentially shippable

NOT a status meeting

Only Development Team can participate

PRODUCT BACKLOG

Single source of requirements and changes to the product

Ordered by unique priority

Never complete

Dynamic and changes as needed responding to changing business needs

Anyone involved can contribute to it

PRODUCT BACKLOG

Highest priority items have the most detail

Detail on lower priority items deferred until it’s needed

SPRINT BACKLOG

Set of Backlog items that the Team commits to delivering in the SprintServes as a real-time picture of how work is progressingBelongs solely to the Development Team

DEFINITION OF “DONE”

A shared understanding of what it means when work is considered done

Defined at the beginning of the project

Applies globally to the project

Might include things such as: - Unit & functional tests - Documentation

USER EXPERIENCE & TESTING

All explained in details Agile_Testing presentation

USER EXPERIENCE TASKS

UX tasks happen slightly ahead of programming tasks

UX expertise stays involved

No big handoffs

TESTING

No distinct testing phase

Features are tested as they are completed during the Sprint they are developed in.

Either developers or dedicated Testers create Unitest
