What is Agile?

Definitions for cocktail party credibility. Helping you sound like you know what you’re talking about.

Agile is not a technology or even a methodology. It is a way of viewing software development through a lens of complexity science. It favors collaboration, conversation and adaptability over rigid plans and structures. There are many Agile methodologies and technologies that have been developed but Agile itself is a philosophical framework.

Themes, Epics, Stories & Tasks: Review

Themes, Epics, Stories & Tasks: Review from Bob Gower on Vimeo.

It’s important that information be presented at the right level of granularity at the right time during the planning process. We use different semantic structures to present information at each stage to avoid an over abundance of detail during strategic sessions and too little information during tactical stages.

Themes, epics, stories and tasks when properly applied keep things simple and keep things moving.

Tasks

Tasks from Bob Gower on Vimeo.

Tasks are created by the development team during a sprint planning session and include all the specific work items that need to be finished in order to complete a specific story.

Stories should be tasked out and each task sized and understood before the team commits to doing the work in a single sprint. If a story is too big for a sprint then it should be broken into two or more stories by the dev team and tackled one at a time.

Stories

Stories from Bob Gower on Vimeo.

A story is a narrow piece of functionality that can be developed in a single sprint. It is a vertical slice through the application that actually adds functionality a user would notice and be able to take advantage of.

That said a story need not be valuable to a user in and of itself and will usually be part of a larger story called an Epic.

Epics

Epics from Bob Gower on Vimeo.

An Epic utilizes the story format but rather than being a narrow slice of functionality that can be developed during a single sprint, an Epic is a set of functionality that is sellable. Once an Epic is completed the business has a new fully functioning capability it can sell to it’s customers. This may take a single sprint or it could take an entire quarter depending on the functionality being delivered.
