Adrenaline Junkies and Template Zombies

Filed under: Learning,Reading — Freek Leemhuis @ 8:34 pm

I’ve followed Tom DeMarco and Tim Lister ever since I read Peopleware, a great book about building great software teams. When a new book by these authors (and a few others) came out last year, I ordered it straight away. It’s called Adrenaline Junkies and Template Zombies, and it’s a great list of patterns of project behaviour.
It’s a fun read, although I’m sure for some of my colleagues and former colleagues some of the stories are too close for comfort.
I’ll describe why a few of the patterns really resonated with me:

At one of my previous assignment there were a lot of procedures to follow. Using project management procedures like Prince2 really revolved around having the specified documents in place at certain to pass certain milestones. Usually, the templates for these documents have little descriptions here and there where information is required.At the start of a project, one had to fill in an document listing predefined architectural concerns and design decisions for the system to be delivered. In itself not a bad practice, but ofcourse only valuable if you put the right amount of detail and consideration into it. As a test, I filled in the template with completely inane comments to see who would pick up on it. Where it asked: what are the logging and tracing requirements for this application I wrote This application has no specific needs for logging and tracing other than standard.
Under the heading: what security concerns need to be adressed for the information contained in the database I wrote : the information needs to be authorized by the guidelines specified in the technical design (note: there was at that time no technical design document – this was to be delivered only in the next project phase). You get the picture. I filed the document and it passed with flying colours: all boxes where checked. In reality, it amounted to nothing.
This kind of behaviour is what DeMarco et al refer to as Template Zombies. If procedures are more about form than content, be very careful. The Template Zombies are out to get you.
The other pattern that lends it’s name to the book is one I deal with quite a bit: Adrenaline Junkies. You will find these people in organizations where priorities are constantly shifting to the project that is particular urgent at that time. A new project was about to start, and after calculating the manpower required to finish on time we concluded that a 4man team should start right away to have any chance of actually meeting the deadline. However, after confronting the project manager with this information, he looked at us stunned, and responded: `are you kidding me? There are 10 more projects that we need to work on before we start that one!’
And so we did not start until it was too late, and ofcourse the project was late like any other project they were doing.
This is the thing when you are dealing with Adraneline Junkies: they react rather than consider, and there is no long-time planning, and generally they confuse being very busy with being very productive. There is generally a lot of burnout and turnover at companies that follow this pattern. Junkie behaviour does not scale, and companies that fail to recognize it will struggle to make a long term impact.
Mind you, the book does not really go into detail on how to handle the situations it describes. It merely gives a name to patterns that are, unfortunately, rife in our industrie. When dealing with Adraneline Junkies I have made my mind up to avoid in particular one other pattern mentioned by DeMarco: I will not be a Film Critic. Go ahead and look that one up, and many other similarly apt named patterns.

JP’s contest

Filed under: .Net,Reading — Freek Leemhuis @ 9:47 am

Jean-Paul Boodhoo is an well-known authority on agily methodologies and patterns in the .Net community. He is author of many published articles, and I have tremendously enjoyed the series of webcasts he has produced for DNRtv on Demystifying Design Patterns.

JP also organizes the Nothing but .Net training bonanza’s, and reading the description of these bootcamp style events have always had me thinking of ways to be able to sign up for one of them. So when he opened a competition for submitting stories that would foster the passion in developers I put in a few words. And lo and behold, I made it in the top 5! So now you can vote for me or any of the other contestants to give your favorite author the chance to enjoy a great week of training.

UPDATE:

So I did not win the top price, so I guess I need to persuade my company to stump up the money for the training course! I did come in third, which JP is generous enough to award with a 130 dollar Amazon voucher. I’m planning to spend it on this set of books:

Feather’s book has had some rave reviews, and I’m curious what tips and practices it offers, especially since I will be working on a lot of legacy code in the near future it seams…
This book apparantly has set a new standard in the publishing of programming books. It’s got syntax code coloring! And it’s a very good book on WPF, which I want to dive into a bit more
McConnel is my favorite author, and this is one of his books I have yet to get my hands on
Uncle Bob is another one of my favorites, and this brand new tome will no doubt contain many a pearl of wisdom. Dispite the ugly cover.

Thanks to JP for stacking up my reading list!

Reading: The Change Function

Filed under: Reading — Freek Leemhuis @ 4:29 pm

 If you build it, they will come.

This quote from the rather corny movie ‘Field of Dreams’ is used by author Pip Coburn to illustrate the mindset with which a lot of technology is build. Innovation is often driven by suppliers and not based on what users are after. In his book The Change Function:Why Some Technologies Take Off and Others Crash and Burn,  he addresses two key issues in the technology industrie:

1. High-Tech Failure rates stink

2. Suppliers think they are in charge but in reality users are in charge

Coburn describes the old school thinking that is paramount in the field as

Change = f(Moore’s Law * Grove’s Law)

Former Intel CEO Andy Grove’s mantra suggests that the surest way to success is to focus on creating disruptive technologies that produce order of magnitude, or “10x” changes that alter the landscape. Moore’s Law can be ascribed to anyone suggesting that as the price drops, the market will flourish.

Coburn does not consider this thinking wrong, but argues that since it focuses on the supplier, not on the users, it is incomplete. It would be better to include the user’s perspective, as decribed by his Change Function:

f(user crises vs. total perceived pain of adoption)

This is a much more user-focused : It’s essential the user is in a crisis to motivate him to move to new products. Just telling him he should use this new technology usually won’t work. The total perceived pain of adoption is the user’s estimate of what it will cost him to adopt the technology. This can be monetary value, but usually the bigger components here are time and effort it takes to learn how to use the technologies.

For example, the Blackberry took off because the perceived crisis is high (lack of access to email while traveling), while the total perceived pain of adoption is relatively low (it’s not that expensive, and easy to use). On the other hand, things like interactive TV have been less succesfull then anticipated because of the lack of perceived crisis.

What I like about Coburn’s reasoning is that it’s user-centric. It’s all about the perception of the user.

It’s a good read, with loads of great quotes, although the large number of examples does get a bit tiresome. It is ofcourse very speculative, and I would have liked to see some scientific research results to back it up. You’d think that with all the money going on in the industry it should not be hard to come up with some solid research.
