What is Agile? Agile software development is a

group of software development methodologies

based on iterative and incremental development,

where requirements and solutions evolve through

collaboration between self-organizing, cross-functional teams.

The Agile Manifesto introduced the term in 2001.

Some Agile Methodologies

Feature Driven Development

Scrum is… One of several agile frameworks in practice today.

Simple in concept, requiring diligence in practice and dedication to a near-term goal. For example:

The product owner must be prepared to dedicate a significant amount of time to the success of the outcome.

Team members must be dedicated to the team’s efforts , not allocated across multiple projects, and willing to do anything they can to deliver on the goal.

The ScrumMaster is the facilitator of the process, not the command-and-control manager of the project. The team and product owner are the drivers on a scrum team.

Scrum is Deceptively Simple…

Stories

Product Backlog The product owner is responsible for the business value of

the project The product owner creates a prioritized wish list called a

product backlog, which is Dynamic—Items may be deleted or added at any time during

the project. Prioritized—Items with the highest priority are completed

first. Progressively refined—Lower priority items are intentionally

course-grained. Articulated as user stories, which are reminders to have

detailed conversations when it’s time to develop: As a <user>, I can <action> so that <result>

Sprint Planning

Sprint Planning During sprint planning, the team meets with the

product owner to pull a small chunk from the top of that wish list, a sprint backlog

The team self-organizes and decides how to implement those pieces.

A sprint backlog is A negotiated set of items from the product backlog

that a team commits to complete during the time-box of a sprint.

Items in the sprint backlog are broken into detailed tasks for the team members to complete.

Spikes Spikes are time-boxed exceptions to the standard

scrum cycle that address a particular “unknown”

A spike is usually an investigation of a user story in order to be able to estimate the work effort.

A spike can also be used to build a proof of concept, secure funding for a project, or expand knowledge about a new technology.

Spikes usually take place between sprints, though can be included in a sprint backlog.

Sprint & Daily Scrum

Sprint & Daily Scrum The team has a certain amount of time, a sprint, to

complete its work - usually two to four weeks – via self-organized, collaborative efforts.

The team meets each day to assess its progress (daily scrum) to share struggles and progress and update the sprint backlog and burn-down chart accordingly.

The burn-down chart is an at-a-glance look at the work remaining (can have two charts: one for the sprint and one for the overall release/project)

Along the way, the ScrumMaster keeps the team focused on its goal, ensuring that the team is functional and productive .

Remaining Units of WorkFast Failure – remove lower-priority requirements from the sprint to ensure the highest-priority ones get done first.

Sprint Review & Retrospective

Sprint Review & Retrospective At the end of the sprint, the team demonstrates to the

product owner what it has completed during the sprint

The work should be potentially shippable, which means that the increment/deliverable could be released to a customer or stakeholder.

The product owner makes the decision about when to actually release any functionality or deliverable.

The sprint ends with a sprint retrospective, where the team, product owner and scrum master look for ways to improve the product and the process.
