The Disciplined Agile Delivery (DAD) decision process framework is a people-first, learning-oriented hybrid agile approach to IT solution delivery. It has a risk-value life cycle, is goal-driven, and is enterprise aware.
There are clearly some interesting aspects to the DAD framework. DAD is a hybrid approach which extends Scrum with proven strategies from Agile Modeling (AM), Extreme Programming (XP), Unified process (UP), Kanban, Lean Software Development, Outside In Development (OID) and several other methods. DAD is a non-proprietary, freely available framework. DAD extends the construction-focused lifecycle of Scrum to address the full, end-to-end delivery lifecycle from project initiation all the way to delivering the solution to its end users. It also supports lean and continuous delivery versions of the lifecycle: unlike other agile methods, DAD doesn’t prescribe a single lifecycle because it recognizes that one process size does not fit all. DAD includes advice about the technical practices such as those from XP as well as the modeling, documentation, and governance strategies missing from both Scrum and XP. But, instead of the prescriptive approach seen in other agile methods, including Scrum, the DAD framework takes a goals-driven approach. In doing so DAD provides contextual advice regarding viable alternatives and their trade-offs, enabling you to tailor DAD to effectively address the situation in which you find yourself. By describing what works, what doesn’t work, and more importantly why, DAD helps you to increase your chance of adopting strategies that will work for you.
The development of the DAD framework was led by Scott Ambler while he was at IBM in their IBM Rational division, starting in mid 2007. The framework was applied at several IBM clients around the work, and evolved based on those experiences plus experiences within IBM itself, over a several year period. In 2012 the book Disciplined Agile Delivery: A Practioner's Guide to Agile Software Delivery in the Enterprise was published via IBM Press. The DAD framework continues to evolve at the Disciplined Agile Delivery home page.
The focus of the DAD framework is on the delivery of software-based solutions from project/product initiation to deployment into production (or the marketplace). It does not address cross-project IT concerns such as Enterprise Architecture nor Portfolio Management to name two. Other methodologies, such as Enterprise Unified Process or ITIL, are better suited for that.
