The three Scrum roles of Product Owner, Scrum Master, and Development Team can certainly appear minimalistic and "lean" from the perspective of a big organization. Why is it then that a Lean-Kanban approach prescribes no particular roles at all, and what lessons might we draw about how a lean or agile enterprise ought to deliver value?

    Agile Development in Practice
    "Agile Development in Practice"


    I was asked to pull the In Practice series together into a book, so I have. Here's the blurb:

    The development of complex systems is fraught with difficulty. Many organizations have taken the vocabulary and outward form of agile practice, but without sponsoring the deep change that agile adoption genuinely requires. The benefits they hope for escape them...and their projects continue to fail. All too often, nothing really changes at all.

    This book tells you what agile practice is really about, and how to achieve it. The essential components of an agile way of working are laid out chapter by chapter. The book concludes with a concise treatment of the agile transformation problem, and shows how to leverage agile patterns and practices in order to resolve it.


    You can buy it at amazon.com. ISBN 978-1-908552-49-5, 260 pages.

    This month’s gargoyle is on Ripon Cathedral in North Yorkshire. The “Cathedral Church of St Peter and St Wilfrid”, as it is formally known, was founded as a monastery by Scottish monks in the 660s before being refounded as a Benedictine monastery by St Wilfrid in 672. The cathedral is notable architecturally for its gothic west front in the Early English style, considered one of the best of its type, as well as the Geometric east window. The seventh-century crypt of Wilfrid's church is a significant example of early Christian architecture in England.

    Today's church is the fourth to have stood on this site. Saint Wilfrid brought stonemasons, plasterers and glaziers from France and Italy to build his great basilica in 672. The Early English west front was added in 1220, its twin towers originally crowned with wooden spires and lead. The east window was built as part of a reconstruction of the choir between 1286-8 and 1330.

    The Doctor Is In...


    Have a question about Scrum or agile practice in general? I hang out in the Scrum Forum and I'm a certified trainer. Post a query there and I'll help if I can:

    scrum.org/Community/Forums

    If you're after an overview of Scrum and what it's about, you can have a look at my presentation Scrum in an Hour. There is also a companion text, The Agile Buddy Guide.

    For the low-down on many topical issues, you can see Agile Tom, the Scrum Shack's resident cat.

    I teach the Scrum.org Professional Scrum Master course fairly regularly. Classes are usually held in Aske Hall in North Yorkshire:

    A little information about me


    I'm Chief Scientist at proAgile Ltd. Agile transformation is my bag. I tweet and blog quite actively about this.
    I'm also the curator at agilepatterns.org.

    Too much information about me


    Hobbywise, I'm into Extreme Ironing. I've ironed underneath the ice-sheet of a frozen lake, and I've also gifted the world with the "fusion" sport of bog snorkelling + extreme ironing.

    I do quite a bit of scuba diving in lakes and rivers, mainly in pursuit of antique bottles.

    Cave diving is another interest, and I have traversed White Lady sump in the Dan-yr-Ogof system while training under the redoubtable Martyn Farr.

    Of course, I have plumbed even murkier depths on public sector IT projects. This latter experience once lead to an outburst of Vogon Poetry; you can commiserate by reading it here.
