Avoiding Iteration Zero

Teams new to Agile often realize that they have a lot to do before they get their new development process at full speed. Looking at this big and unknown hill in front of them, many Agile teams choose to do an Iteration Zero (or Sprint Zero) to prepare before they start delivering regular increments of functionality. During this time, they may try to get their ducks in a row with
  • A list of features to be built
  • A release plan or timeline for those features
  • Setting up development infrastructure such as version control or continuous integration servers
  • Studying or practicing skills in new technologies they expect to use
  • … and other management, infrastructure, and technical endeavors.
They try to get all the preliminaries out of the way so they can hit the ground running full speed in Iteration One. In my experience, they’re still not ready to go full speed. These things are rarely as complete as expected after one iteration, and often aren’t quite in tune with the actual needs of the project.  The list of features will likely not be complete, but the attempt to approach completeness will dump in lots of ideas that have been given little thought. Any attempt to project into the future still has no data about how fast things can be accomplished. The infrastructure may or may not be the best for supporting the project, but it is likely that the project will now conform to the infrastructure rather than the other way around. The choice of technologies will be made speculatively rather than driven by the needs of the project. While we may do OK, we’ll have made a lot of decisions with the least amount of information we’ll have in the project lifecycle. And we’ll have burned an iteration without producing any working software that tests our decisions. My advice is to borrow an idea from Lean and look at the situation from the output point of view.  Ask yourself, “what would it take to start delivering?” The initial backlog really only needs to be one item in order to start delivering.  If you’ve got too many unknowns, then just start with one item.  Get the business stakeholders, the programmers, the testers, and anyone else who needs to be in on the discussion (User Experience? Ops?) to talks about it.  (I call this a meeting of the Three Amigos.)  What is the one obvious thing that needs to be done? (Hint: it’s not “login.” Start with the main purpose of the system.) I can’t imagine a situation where a project is started without any ideas at all. Take that one thing, and slice it into thinner slices.  Decide on the examples that represent acceptance of those slices.  Some of the slices will have questions that can’t be answered.  Put those aside for the moment.  Choose the most central slice that travels through the entire concept from end to end, or as close to that as possible.  Estimate that as one team-iteration.  (Estimates don’t have to be “right.” They’re just estimates.)  Start building it. Learn the necessary skills in the technology while accomplishing real work. Learn the parts that aid building the system, rather than developing the system according to some framework. When you don’t know how to accomplish something, or you think multiple approaches might work, do minimalistic spikes to give the information needed to make a decision. Along the way, start slowly building your development infrastructure. Set up a local code repository. You can always migrate the code to an “official corporate” repository later.  Right now, there’s not much code. Set up a simple build-and-test script so that everyone builds in the same fashion. You can always add other build targets later. If you’ve got time, you can set up a Continuous Integration server. Otherwise, just do it manually. Checkout & build into a clean workspace. Do what’s needed to run the code so that you can show it working. If you can’t accomplish this slice in one iteration, it’s probably not thin enough. Or, maybe you haven’t yet solved an essential technical problem. Or the goal isn’t yet clear enough. Figure out what impediment is most in your way, address that, and try again. More likely, you’ll get this slice done in less than a iteration length. If you get this slice done before the end of the iteration, then pull in another slice.  Estimate this as “the rest of the iteration.”  Repeat as needed.  As long as you’ve gotten one slice done, you’ve got a potentially deliverable product increment. Yes, there will still be development infrastructure to be developed. There’s no particular rush to get that done. Just keep improving it, so that it helps you get more done. Yes, there will still be technical skills to be developed. That should always be the case. Just keep experimenting and pushing your limits. Yes, there will still be features to be added to the backlog, refined, prioritized, split into stories, and prioritized again. This should continue throughout the project. It’s part of the “steering” process. Yes, there will still be a need for projections to estimate when functionality can be released, or how much functionality can be released by a certain date. When you think you’ve got enough information about what needs to be done, then consider the initial release plan.  By then you’ll also have accumulated a little information about how fast things get done. There will still be a lot of holes in your knowledge of what needs to be done and how fast things get done.  Don’t trust your initial release plan to be “right.”  It’s just a stick in the sand to help you judge how things are going.  Keep planning, and move the stick as needed. And as time passes, you’ll have a better and better indication of how fast the system gets developed. Even when you think the Release Plan is complete, it needs to be continually reviewed and adjusted. Since it’s never done until the release, there’s no particular hurry for a certain level of completeness. This sort of beginning is very like the Hudson Bay Start that Johanna Rothman describes in her book, Manage It (pp. 52-53).
The Hudson Bay Start approach was originated by the Hudson Bay Company in the 1600-1700s in northeastern Canada. The Hudson Bay Company outfitted fur traders. To make sure the traders hadn’t forgotten anything they needed, they left Hudson Bay and camped just a few miles away. By making camp just a few miles away, the traders ensured they hadn’t forgotten any tools or supplies–before they abandoned civilization. With just a short start to their journey, they had a better idea about their ability to endure the winter.
There’s really no reason (other than “that’s not the way we do things around here”) that this can’t work for the start of any team/project. It’s a great way of learning the right stuff for the current situation while also making a bit of progress. I use this technique in my Agile in Six Months transition plan.

What People Say

“Kelly revolutionised the way our digital department operated. A true advocate of agile principles, he quickly improved internal communication within our teams and our internal clients by aligning our business and creating a much enhanced sense of transparency in the decisions the business was making. Kelly also introduced a higher sense of empowerment to the development teams...”

PETER SILVA-JANKOWSKI
IPC MEDIA

“Kelly’s a leading program director with the ability to take charge from day one and keep strong momentum at both a program and project level driving prioritisation, resourcing and budgeting agendas. Kelly operates with an easy-going style and possesses a strong facilitation skill set. From my 5 months experience working with Kelly, I would recommend Kelly to program manage large scale, complex, cross company change programs both from a business and IT perspective.”

LUKE SHARKEY /STRATEGY & IMPLEMENTATION LEADER
SUNCORP

“Kelly is an extremely talented and visionary leader. As such he manages to inspire all around him to achieve their best. He is passionate about agile and has a wealth of experience to bring to bear in this area. If you're 'lucky' he might even tell you all about his agile blog. Above all this, Kelly is great fun to work with. He is always relaxed and never gets stressed - and trust me, he had plenty of opportunity here! If you get the chance to work with Kelly, don't pass it up.”

GILES BENTLEY, DEVELOPMENT & OPERATIONS DIRECTOR
TIME INC

“Kelly is an Agile heavy-weight. He came in to assess my multi-million $ Agile development program which wasn’t delivering the right throughput. He interviewed most of the team and made some key recommendations that, when implemented, showed immediate results. I couldn’t ask for more than that except he’s a really nice guy as well.”

DAN PULHAM, DIGITAL DIRECTOR
TELSTRA

“Kelly and I worked together on a very large project trying to secure a new Insurer client. Kelly had fantastic commercial awareness as well as his technical expertise. Without him I would never had secured this client so I owe a lot to him. He is also a really great guy!”

GINA MILLARD
GLASS'S INFORMATION SERVICES

“Kelly came to the department and has really made a huge impact on how the department communicates, collaborates and generally gets things done. We were already developing in an agile way, but Kelly has brought us even more into alignment with agile and scrum best practices, being eager to share information and willing to work with us to change our processes rather than dictate how things must be done. He is highly knowledgable about agile development (as his active blog proves) but his blog won't show what a friendly and knowledgeable guy he is. I highly recommend Kelly to anyone looking for a CTO or a seminar on agile/scrum practices - you won't be disappointed!”

ANDY JEFFRIES/TECHNICAL LEAD
IPC MEDIA

“Kelly was a great colleague to work with - highly competent, trustworthy and generally a nice bloke.”

HANNAH JOYCE
GLASS'S INFORMATION SERVICES

“Kelly was engaged as a Program Director on a complex business and technology transformation program for Suncorp Commercial Insurance. Kelly drew on his key capabilities and depth of experience to bring together disparate parties in a harmonised way, ensuring the initiate and concept phases of the program were understood and well formulated. Excellent outcome in a very short time frame. ”

BRUCE WEIR/EGM
SUNCORP

“I worked with Kelly on many projects at IPC and I was always impressed with his approach to all of them, always ensuring the most commercially viable route was taken. He is great at managing relationships and it was always a pleasure working with him.”

BEATRIZ MONTOYA/CONSUMER MARKETING DIRECTOR
