What is Agile Scrum Methodology?

One of the most popular agile methodologies in use today. Scrum is a lightweight software development methodology that focuses on having small time-boxed sprints of new functionality that are incorporated into an integrated product baseline. Scrum places an emphasis on customer interaction, feedback and adjustments rather than documentation and prediction.


Why Use Scrum and Extreme Programming (XP)?

Traditionally projects are delivered in a series of phases that are based on increasing levels of certainty around the system being built:

However this approach has many drawbacks:

  • It is not flexible to changes in customer requirements
  • Time is wasted building features that nobody needs
  • The end user cannot give feedback till it’s completed coded
  • You don’t know how stable the system is until the end

How Is Scrum Different?

One of the most popular agile methodologies in use today. Scrum is a lightweight software development methodology that focuses on having small time-boxed sprints of new functionality that are incorporated into an integrated product baseline. Scrum places an emphasis on customer interaction, feedback and adjustments rather than documentation and prediction.

Instead of phases, Scrum projects are broken down into releases and sprints. At the end of each sprint you have a fully functioning system that could be released:

With scrum projects, the requirements for the project do not have to be codified up-front, instead they are prioritized and scheduled for each sprint. The requirements are composed of ‘user stories’ that can be scheduled into a particular release and sprint:

Scrum is often deployed in conjunction with other agile methods such as Extreme Programming (XP) since such methods are in reality mostly complimentary, with XP focusing on the engineering (continuous integration, test-driven development, etc.) and Scrum focusing more on the project management side (burn-down, fixed scope for sprints/iterations). So project managers should choose elements of the Scrum project management methodology and other methods/tools together for the specific project. Since Scrum is a more defined project management methodology in terms of tools and processes, it is often easier to adopt from day one with less initial invention and customization.

How Is Extreme Programming Different?

The idea developed by Kent Beck was to use best programming practices but take them to the extreme – hence the name. As such, none of the individual concepts of XP are really new, but their application and combination is what makes XP different, or at least did in the 2000s, which is when it initially became popular. XP advocates adaptability; recognizing that each project faces different problems, applying those methods that will work and discarding those that will not. Partial XP therefore becomes a true possibility, often combined with Scrum, which has gaps in its definition particularly suited to adoption of XP practices.

XP embraces standard Agile principles such as short iterations; requirements being loosely defined with user stories until they are needed; almost immediate and regular testing; close, on-site stakeholder involvement with a rapid feedback loop; and team responsibility for success or failure.

As is necessary for Agile projects, the XP team expects and accepts changes in requirements based on feedback from stakeholders and the obligatory high level of communication within the team. Intense communication is necessary because everyone is required to understand the system as a whole so that anyone can work on and change any of the code. Quickly written code is often used as a means to explain ideas and try out designs. With short iterations comes regular layering of new functionality, thus refactoring is encouraged in order to consolidate separately written parts into a more efficient whole.

Testing taken to the extreme means using as many testing techniques as necessary, as often as possible. Methods include unit testing, acceptance testing, integration testing and test-first programming.

Pair programming is part of XP, the idea being that two heads are better than one. Using only one workstation, one person writes code while the other observes, injecting ideas, pointing out potential problems and thinking about the ‘big picture’ as the code is written. Roles are reversed frequently and the pair work as if joined at the hip. If a pair get too comfortable with one another they may begin to think alike and two heads thinking as one is no better than one head, defeating the purpose. Pairs should be split up and reassigned when this happens. While pair programming does increase staffing needs, it is an excellent technique for building in quality which is an Agile ideal.

Finally: Simplicity. The simplest solutions are encouraged, addressing the immediate problems, not problems that might arise tomorrow. This helps everyone to remain focused and meet deadlines but can result in considerable redesign and refactoring over time. To avoid architectural dead-ends, spike solutions are recommended, whereby the team creates user stories to prove out areas of most technical or conceptual risk. This, together with refactoring build into every iteration, prevents the system becoming atrophied and unable to support future needs.

One of the reasons XP is so popular is its flexible nature. It is easy to combine features of XP with other ideas; indeed, XP is more about technique than process and so dovetails well with process-centric approaches such as that of Scrum.
