Incremental delivery planning is not an oxymoron. You just plan the soon-to-happen tasks in detail, and keep the distant tasks more vague. Does this make sense? Rolling-Wave Planning Johanna Rothman has posted an article that provides a good introduction to rolling-wave planning. She explains that she manages incremental projects with […]

Foundation Series: Continuous Integration
Continuous Integration is the software development and quality process where all team members merge their code and verifies it frequently – at least daily. This verification project includes both an automated build process and automated testing. The main benefits of continuous integration come from risk-reduction and cost-reduction.

The Agile Dragon
When Alan Cooper and Kent Beck debated the benefits of eXtreme Programming versus Interaction Design, they disagreed on a lot of things. One thing they agreed on is that Agile processes are designed to minimize the impact of changing requirements. Cooper believes that it makes more sense to minimize future change by understanding the requirements better up front. Beck believes that the requirements can not be understood by the team until something is delivered. Beck’s point is that the customer doesn’t understand the requirements until he has something in his hands. We’ve shown how this is both a strength and a weakness for Agile in the real world. In The Hobbit, the dragon Smaug was missing a scale on his belly, that made him vulnerable. Agile processes have a similar weak spot.

Where Did You Get That Estimate?
How good are our estimates? We can use PERT to estimate the time it will take to implement each requirement. We can use timeboxes to schedule the requirements within each release. If we don’t know how good our estimates are, its an exercise in futility. Scheduling is about more than predicting the future, its about knowing how much faith to have in our predictions.

Gartner research on Agile Requirements Definition and Management (RDM)
Gartner has a research report available for $95, titled Agile Requirements Definition and Management Will Benefit Application Development (report #G00126310 Apr 2005). The report is 7 pages long and makes an interesting read. Gartner makes a set of predictions for 2009 about requirements definition and management (RDM) systems, and the software created with RDM tools. Gartner misattributes several benefits of good process to RDM tools. We give them a 3.5/7 for their analysis – check out the details here.

Two big benefits of incremental delivery
Tarun Upadhyay wrote a fair criticism of our previous post on why incremental delivery is good on his blog today. It is great that he is extending the conversation, and he makes some valid points. We definitely missed a big benefit of incremental delivery, and will cover it in this post.

Scheduling requirements changes – part 2
This process goes against agile principles on paper, but makes teams more agile in practice. Scheduling delivery of a project is an exercise in managing complexity. Scheduling changes to the requirements on the fly is really only marginally more difficult. The key to managing changes is to set expectations with our stakeholders. By defining rational deadlines for change requests, we assure ourselves that we can manage the changes. We also demonstrate responsiveness to our stakeholders. Rational deadlines are not arbitrary deadlines nor are they unreasonable deadlines. Deadlines that vary with the complexity of the changes are rational, easy to communicate, and easy to manage.

Why Incremental Delivery Is Good
Incremental delivery is a key component of most software projects today – it allows us to deliver the most valuable elements of a system first, which allows our customers to start getting benefit from the system earlier. As additional features are developed, and additional use cases are enabled, they are delivered to the customers, who get incremental value from those features. This can have a significant impact on ROI projections for a project – and can be the difference between getting the deal and losing it.
