Title: Scrum and XP: Myths, truths and how to do it.

Description: Scrum and Extreme Programming are two common Agile frameworks. You may have heard that Scrum is equivalent to XP without technical practices. Or, perhaps you have heard that Scrum is only a project management framework. The presentation intents to explore the truth in these matters and to discuss how to effectively integrate the XP technical practices within the Scrum framework.

Some differences of Scrum and XP

Scrum is agnostic with regard to technical practices

The Scrum model for Roles and Responsibilities is better defined

The Scrum Timeboxes (meetings) are better defined

Scrum explicitly lists Scrum artifacts: Product Backlog, Sprint Backlog, Release Burndown, and Sprint Burndown

Some differences of Scrum and XP

The XP model for technical practices is better defined

The XP model for a Continuous Process is better defined

XP introduces concepts that make delivering an increment of potentially shippable code possible

Combining Scrum & XP

Avoid ... mandating that all XP technical practices be adopter. Rather, educate teams on the different practices and allow them to decide when and how to adopt them.

Avoid ... unrealistic expectations. Rather, recognize that this is a paradigm shift in how teams write and deliver software, and expect that this will take time.

Avoid ... adopting Scrum without changing technical practices. Rather, recognize the limitations of existing technical practices and educate teams in the XP technical practices and their implications.

A Quote

Most high performance teams use Scrum and XP together.

Higher Performance

By using XP Technical practices we can deliver high quality software at the end of every Sprint

And, its only when we can deliver high quality software on a regular basis that we can know the true rate at which we can deliver functionality to the business

Combining Scrum and XP is a powerful way of taking your team to the next level

Build something beautiful and inspiring!
