The idea behind a "Sprint Zero" is that, where initialization demands time and effort before any empirical demonstration of value can be provided, it should still be accounted for in terms of a Sprint of some kind. The weakening of empirical process control, and the delayed delivery of value, might reasonably be identified as negative outcomes of such an approach. There is also a danger in norming the idea of a Sprint which does not actually yield a product increment. Sprint Zero has been discouraged by Scrum.org, and its use criticized by two of the signatories of the Agile Manifesto. In this article we consider these issues and look at some better alternatives.

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.

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. I also teach the Professional Agile Leadership course. See Upcoming classes

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.

Gargoyle of the Month


Ludlow Castle gargoyle, via Wikimedia Commons
This month’s gargoyle is from Ludlow Castle, a ruined medieval fortification in the town of Ludlow, Shropshire, near the Welsh border. It stands on a promontory overlooking the River Teme, and was one of the first stone castles to be built in England. It was further extended in the later medieval period with a Great Tower, outer bailey, and additional building.

Ludlow Castle was chosen as the seat of the Council in the Marches of Wales, effectively acting as the capital of Wales, and it was extensively renovated throughout the 16th century. By the 17th century the castle was luxuriously appointed, but fell into disrepair following the Civil War.

The architecture of Ludlow reflects its long history, retaining a blend of several styles of building. English Heritage notes that the ruins represent "a remarkably complete multi-phase complex" and considers Ludlow to be "one of England's finest castle sites".
