Guess who? (Kill the Agile Buddha)

Guess who am I now.

I’m in a supermarket, I’m pushing a trolley. I’m putting items into it. I just need some bread and I’ll be going to the checkout. Who am I?
I’m in a bank, queueing up in front a machine for depositing cheques. I’ve got a couple of cheques I need to pay in. Who am I?
I’m in an electronics store. I want a new printer but I’m not sure what’s the best for me, I’m looking for someone to help me. Who am I?

Or maybe what am I?

I am a customer.

Aren’t I?

Business language backs up my assumption. The employee at the supermarket checkout is called a Customer Service Rep, my personal (customer) details are held in the banks Customer Relationship Management system, in the electronics store I’m looking for Customer Support. And after I’ve bought my printer I’ll be asked to complete a Customer Satisfaction Survey.

So everything indicates that I am a customer. Or that is what I thought I was.

Apparently not according to the Scrum zealots.

At Agile 2009 Tom Illmensee presented a paper “5 Users Every Friday: A Case Study in Applied Research”. It describes how an eCommerce division of an electronics retailers introduced agile and how the user experience team adapted to agile. It starts by describing how their initial forays into agile were deemed successful. It was collaborative with the disciplines well integrated; “whiteboard wireframes, minimal documentation, and product demos. Usability tests with paper and semi- functional prototypes were conducted with shoppers each sprint”. More than that, the whole team enjoyed the experience. A decision was made to “take agile to the next level”. The next level was the introduction of a consulting firm who brought in scrum training. The scrum dogma was painful to adopt, but they got there in the end. But there’s a line in the paper that made me angry:

“The peculiar semantics of Scrum were especially confusing at first. In retail customers were people who bought things like stereos and flat-screen TVs. Not anymore. Agile had changed the definition of perhaps the most important word in our business environment: customers were now internal product owners. Customers would now be referred to as shoppers—or users.”

I’ll write that again. Customers (the people who the business depended upon, and “the most important word in [their] business environment”) would now be called shoppers. Or users. Because in agile, customers are internal product owners.

Sorry, these consultants, these agile zealots, these software egos have got too big for their boots. Dan North, pulling to pieces the nonsense of ‘software craftsmanship’ put’s it eloquently:

Software Craftsmanship risks putting the software at the centre rather than the benefit the software is supposed to deliver, mostly because we are romantics with big egos. Programming is about automating work like crunching data, processing and presenting information, or controlling and automating machines.

Software at the centre rather than the benefit the software is supposed to deliver. Software is the means to an end, not the end itself. If a certified scrum master (certified master based on two days training and a multiple choice questionnaire, now there’s a farce) tries to rewrite your business language, tries to tell you that your domain language is wrong, show him or her the door.

There’s a budhist saying “If you see the Buddha on the road, kill him“.

If you see agile in your workplace, kill it.

Why kill the Buddha? because the Buddha becomes an object, your own illusion of what it is. And it this illusion is wrong.  To turn the Buddha into a religious fetish is to miss the essence of what he taught. Killing the Buddha means taking responsibility for yourself.  Same with Agile; to turn agile, to turn software development into a religious fetish is to miss the point of what it is all about.

I presented on the customer theme a while ago, here are the slides.

And here’s me narating the slides on google video.

Design vision

Don’t be fooled into thinking that you don’t need to do any design when you adopt Agile.  Agile development strives to deliver business value early and often, focusing on getting working software to market as soon as possible rather than dwelling in documentation and ‘analysis paralysis’.  But let’s be clear, “business value” and “working software” are not the same thing.  You can quite easily get something into production that fails to generate revenue, decrease costs or whatever other yardstick you use for ‘value’.  What differentiates the two of them is design.  I don’t mean big up front design that details all the features and provides a concrete spec, I mean a design vision that articulates what the product goals are and a roadmap for getting there.  And what is a design vision?  A short statement of intent is a good place to start, and soon after a user interface mocked up in pen and ink.  It is cheap and easy and helps bridge the path from idea to execution.

Sounds like a case for agile

..CIOs will be expected to become more and more strategic, delivering greater productivity gains while at the same time ruthlessly cutting costs. There will be a heightened debate about the role of IT in the enterprise. (ComputerWorld)

OK, so we can either spend months writing documents before a line of code is written. Do some application development then manually test what we’ve built and fix the bugs before eventually going live (late and over budget and not to the customers satisfaction).

Alternatively we could get more strategic and focus upon what value we can deliver in the shortest period of time. We could better align IT with the enterprise by delivering early and often, enabling us to test and learn from the enterprise as we go. We could adopt a more ‘just in time’ approach to requirements (whilst starting with a clearly defined vision from the outset). We could build testing into the development to lessen the bugs at the end, we could do automated testing (to ruthlessly cut manual testing costs). Downturn sounds like a case for agile.

How are you managing the change?

To the development team ‘change’ relates to scope and requirements within the project, but change runs far deeper than that.

A question that I am often asked is how do you manage business change on agile projects. Release regular and often is an often quoted mantra, but what does that mean to the business where rolling new software across the large, multi-site organisation? How do you manage the piecemeal introduction of new technology, features and functions to hundreds or thousands of people, many levels removed from the project across remote offices and geographical locations? How do you ensure the recipients of the new technology rapidly adopt it and accept the change, even when change is occurring every few months.

What are the financial and human performance implications of each new release in terms of training, productivity and morale? What is the overall burden on people in frequent change?

The reality is that it is not unusual for projects deemed successful by IT and the immediate business team to ultimately fail when released to the broader organisation. Effective change management can be even more important when an organisation adopts agile software delivery.

An analogy as an example. If I expect a screwdriver and you only give me a cross-headed screwdriver when I really want a flat head one I am going to be unhappy. The core team may have prioritised the cross-headed one first for good reason, a flat headed one maybe coming just round the corner, but if you don’t deliver to my expectations I am going to be unhappy. Worse, I am likely to become resistant to future change and less likely willingly cooperate with the uptake of future releases, even if they do start to deliver to my needs.

Keep it on the shelf
The first point is that regular and often does not necessarily mean release to production for the entire organisation or marketplace. Running a number of internal releases, keeping them on the shelf until a complete and marketable product is ready is a strategy often employed. Significant value can be accrued by getting tested and working software into a pre-production environment and held “on the shelf” awaiting a full release. This maybe a UAT environment where a limited number of stakeholders test the functionality in an ‘as-live’ environment. Or it maybe a beta release to a small, selected number of interested people (e.g. a ‘friendly user trail’). This can often pay dividends with usability issues and minor gripes being picked up and addressed before a major roll-out.

Communication

Let’s assume that the team wants to roll out the application early and often to the whole target population. Critical to the success of managing the business change is communication. It is important to manage expectations on a timely and appropriate manner. Explain what the upcoming release will do and more importantly what it will not do (and when it will do it). Keep all stakeholders informed of the project progress (setting up a project blog can be a cheap and easy way of letting interested people know of progress), yammer maybe another way of broadcasting updates and information. Having a release count-down can also prepare stakeholders for the change. The techniques can be googled, the important thing is to communicate and manage the expectations (and be ready for inbound questions and comment after go-live).

Adaptable user interface
It is not unusual for the core team to drive for as much functionality as possible in the first release, considering UI enhancements as ‘nice to haves’ and consigning them to later releases. This is a false economy. Consider the cost of training and lost productivity through a hard to use interface. Now multiply that across multiple releases that focus upon utility before usability. Delivering a first release that is self contained and compelling will go a long way to driving organisational buy-in of the new application and greater acceptance of future change. (Jeff Patton writes some great stuff on using story maps to explain what the system should do. Using these will help focus on complete and useful slices through the application rather than random features that are perceived to be of value but do not make a coherent product).

A new user interface, however well designed will inevitably take time to learn the first time it is used. The challenge is with each subsequent release to introduce funcitonality and interactions that leverages the users existing mental model of the application, building upon what has been already been learned. Starting with the end-state, wireframes that articulate the final application then trimming out features, feields and controls to represent each notional release can be a good way of ensuring a UI that will scale as new functionality is added.

Agile organisation
Ultimately the most successful way of introducing agile is to build a beta culture with everyone as agents of change across the whole organisaiton. More importantly change becomes a cycle of learning and continuous improvement. And here I’ll borrow this most excellent graphic from David Armano. David compares what he calls conventional and unconventional marketing but the parallel with software development is obvious. His iterative cycle is “plan-design-launch-measure” but that is not a million miles away from the lean philosophy of “plan-do-check-act”. And critical to the journey is the learning cycle between iterations.

Better, faster, cheaper…

Here’s a presentation I gave a while ago to a bunch of senior execs, introducing the concepts of lean and agile to software development.  Many of the slides are taken from a presentation given by Richard Durnall which can be found on the ThoughtWorks website [pdf].  If nothing else, the slides about the problems with conventional development methodologies – that they take time, are not responsive to change and rarely end up satisfying all stakeholders, struck a chord with the audience I presented this to.
