Working in the Web Development industry it’s easy to get the impression that everyone involved in software knows about Agile and is at least paying it lip service even if their processes are not really Agile in practice. Clearly this is not the case. The Unmitigated Disaster Known As Project ORCA describes how Mitt Romney’s team attempted to win the race to get voters out to the polls using new technology but fell at every hurdle. It presents us with a textbook copy of everything that can go wrong in software delivery with (depending on how significant its impact) potentially election losing consequences for Mitt Romney and the GOP.
The following are some of the glaring errors made that would have been avoided using Agile/Lean techniques:
- Putting a mission critical piece of software to its first real use on a day when failure was not an option.
- Giving themselves no opportunity for feedback or pressure testing and gaining no validated learnings as to whether what they had built would even work – conceptually, functionally or practically
- Using a top-down approach that ignored the huge amount of skills, knowledge and experience that could have come from the greater team (those on the ground that would have to use the product)
- Convincing themselves they had a product so great that it was better to keep it under wraps and maintain the element of surprise than it was to allow the product to be pressure-tested by the people that were going to use it
Agile software development recognises that you will not get it right in version one, that a delivery team needs to include its end users, that software improves iteratively and that not only your software but your business model itself must be able to pivot and adapt to the realities on the ground and the feedback you receive.
This is what Jason Fried of 37signals did when he gave his company a month to work on projects of their own choosing.
Sounds radical at first thought but if you have dedicated passionate people it makes a lot of sense. It’s the staff involved in the day to day running and building of your business that are most likely to know what your business needs. Fried has given them an opportunity to demonstrate what’s needed and the solutions to those needs.
How can you afford to do this? How can you afford not to? Argues Fried: “We would never have had such a burst of creative energy had we stuck to business as usual.”

Wonderful short video on how to be a Product Owner – should be required viewing for all PO’s and similarly essential viewing for anyone that’s trying to understand the principles of Agile. Captured in this video is the essence of Agile product development. Watch it once and if you don’t understand it all, watch it again. But most importantly, if you are a Product Owner, note the parts about working closely with the team.
My team at Westfield.com are always trying to educate the business sponsors to implement the simplest possible thing – to release the minimum viable product and generate validated learnings rather than implement gold-plated visions of what marketing folk think that people want.
Francis Is shows how successful Heroku were at doing this in Heroku’s Early History.
Heroku’s first offering bore little resemblance to what they finally became but it allowed them to pivot and adapt: to drop the offerings that no one cared about (online code editors, no deployments) and concentrate on the stuff they did (github integration, scalability). Early releases discovered what users really wanted and mining that seam of ‘want’ resulted in exponential growth and a $212 million cash buy-out within 3 years.
We are currently coaching a new team into the ways of Agile and one of the problems we’ve encountered is getting the devs to write cards or stories using the standard Agile story formats. To Agile newbies the syntactic sugar that surrounds a story’s details often seems like a waste of time. i.e. A developer knows exactly what he means when he writes:
“Add currency code to Data Warehouse views”
and feels like he is being made to jump through hoops to turn that into:
“In order to differentiate between international sales, we need to update the data warehouse transactional views to show the currency code, so that they can report on this data.”
The reason we favour this (or the “As a [user]…” format) on agile projects is that the story describes what needs to be done and why. This means that any member of the team can understand exactly why a story has been added to the backlog and doesn’t need to get an explanation from the person that wrote the story or drill down into the acceptance criteria to discover this.
The other benefit of this format is that it forces the person writing the story to find out exactly why the requester wants that story. Indeed, in drilling down to the real requirement, the analyst may discover that the real business requirement is not what the requester is asking for at all.
Aslak Hellesoy (the creator of Cucumber) illustrates all this perfectly in the cucumber documentation where he describes the process of asking the Five Why’s to discover the underlying requirements – the why in the story.

[5:08pm] Luis_Byclosure: I’m having problems applying the “5 Why” rule, to the feature
“login” (imagine an application like youtube)
[5:08pm] Luis_Byclosure: how do you explain the business value of the feature “login”?
[5:09pm] Luis_Byclosure: In order to be recognized among other people, I want to login
in the application (?)
[5:09pm] Luis_Byclosure: why do I want to be recognized among other people?
[5:11pm] aslakhellesoy: Why do people have to log in?
[5:12pm] Luis_Byclosure: I dunno… why?
[5:12pm] aslakhellesoy: I’m asking you
[5:13pm] aslakhellesoy: Why have you decided login is needed?
[5:13pm] Luis_Byclosure: identify users
[5:14pm] aslakhellesoy: Why do you have to identify users?
[5:14pm] Luis_Byclosure: maybe because people like to know who is
[5:15pm] aslakhellesoy: Why would anyone want to know who’s publishing what?
[5:17pm] Luis_Byclosure: because if people feel that that content belongs
to someone, then the content is trustworthy
[5:17pm] aslakhellesoy: Why does content have to appear trustworthy?
[5:20pm] Luis_Byclosure: Trustworthy makes people interested in the content and
consequently in the website
[5:20pm] Luis_Byclosure: Why do I want to get people interested in the website?
[5:20pm] aslakhellesoy: 🙂
[5:21pm] aslakhellesoy: Are you selling something there? Or is it just for fun?
[5:21pm] Luis_Byclosure: Because more traffic means more money in ads
[5:21pm] aslakhellesoy: There you go!
[5:22pm] Luis_Byclosure: Why do I want to get more money in ads? Because I want to increase
[5:22pm] Luis_Byclosure: And this is the end, right?
[5:23pm] aslakhellesoy: In order to drive more people to the website and earn more admoney,
authors should have to login,
so that the content can be displayed with the author and appear
[5:23pm] aslakhellesoy: Does that make any sense?
[5:25pm] Luis_Byclosure: Yes, I think so
[5:26pm] aslakhellesoy: It’s easier when you have someone clueless (like me) to ask the
stupid why questions
[5:26pm] aslakhellesoy: Now I know why you want login
[5:26pm] Luis_Byclosure: but it is difficult to find the reason for everything
[5:26pm] aslakhellesoy: And if I was the customer I am in better shape to prioritise this
feature among others
[5:29pm] Luis_Byclosure: true!
Employee Handbook describing Valve’s completely flat management structure. Not exactly a methodology that you could apply to a big shareholder owned corporate but a great example of how successful you can be if you hire good people and allow them to get on with their job.
In my job at westfield.com we’ve been dealing with the challenge of scaling a development team for years and are yet to get it anywhere near optimum.
This is great post on scaling a team from a company that should know all about it – Heroku.
This is a great way to think about scaling and well worth a read although I think that most of the challenges one will meet scaling a team are not answered by this post – i.e. exactly how and along what lines you break up your teams. It’s interesting to see that the way Heroku broke up their teams was along horizontal layers rather than through functional areas but this probably reflects the highly technical nature of Heroku’s business.
We are currently undertaking a team restructure and I have been convinced for some time that to minimise friction, distraction and duplication, our teams at westfield.com need to be structured based on vertical slices of business functionality; allowing teams to own certain areas and functions of the site and business.
I’ll post again with an update when the teams are restructured and the results are in..
