A Product Owner can be described as a "value maximizer", but how is value calculated? In this article we look at how empiricism ought to underpin any assessment, and at how the discipline of "Innovation Accounting" can challenge predictive value assumptions.

    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 is a gargoyle on Winchester Cathedral in England. The building is unusually large, with the longest nave and greatest overall length of any Gothic cathedral in Europe. It was founded in 642 on a site immediately to the north of the present location. This building became known as the Old Minster. In 1079, Bishop Walkelin began work on a completely new cathedral. A substantial amount of the fabric of Walkelin's building, including the crypt, transepts and the basic structure of the nave, survives. The cathedral possesses the only diatonic ring of 14 church bells in the world, with a tenor (heaviest bell) weighing 1.81 tonnes.

    Nowadays the cathedral draws many tourists as a result of its association with Jane Austen, who died in Winchester on 18 July 1817. Her funeral was held in the cathedral, and she was buried in the north aisle.

    Winchester Cathedral is possibly the only cathedral to have had popular songs written about it. "Winchester Cathedral" was a UK top ten hit and a US number one song for The New Vaudeville Band in 1966.

    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:


    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 seeĀ Agile Tom, the Scrum Shack's resident cat.

    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.
