Great Design

Fred Brooks in an interview with Wired:

“Great design does not come from great processes; it comes from great designers.”

This seems so natural and correct when talking about design. Applied to other professions, you might see:

  • Great software does not come from great processes; it comes from great developers.
  • Great engineering does not come from great processes; it comes from great engineers.
  • Great testing does not come from great processes; it comes from great testers.
  • Great management does not come from great processes; it comes from great managers.

Yet time and time again, we lean back on the processes that in the best of situations are mediocre and brittle.

Beliefs

Beliefs: The framework of things you hold to be true, and of which form the basis for all of your decisions.

Here are some of mine. Which do you disagree with? Why?

Workarounds are never a good thing. Short term workarounds are never short-term. They should be avoided. Do it right the first time, and if you can’t due to time or budget, delay the project. I hate technical debt.

Plan as you go is more appropriate to life and to projects, and returns better results, than planning everything up front (ie agile vs. waterfall). What we are talking about is predicting the future. Sure, you can be somewhat accurate, some of the time. But it’s just a guess. You’ll be more accurate if you don’t predict too far out. If you’re more accurate, you’ll be happier.

The problems of new are less than the problems of the old. On occasion you will run into a bug by upgrading software to the latest version. But I’ve found that on balance, I have far fewer compatibility & stability problems if I keep up to date. And as a bonus, new features!

Buy the well-built item once instead of the cheap thing multiple times. It’s eco-friendly, and you get to have the quality item to use every day. My wife and I had been wearing out a $10 garlic press once every 12 months or so with basic wear and tear — till we bought the Rösle Garlic Press for (at the time) $30. Five years later, it still looks good as new and works brilliantly.

Price is not correlated to the value. Just because it’s expensive doesn’t mean it’s worth a lot. Conversely, just because it’s cheap doesn’t mean it has no value. Open-Source Software, Wikipedia, a walk with your kids – these all have a lot of value, and they don’t cost you a dime.

Deals are rarely worth it. Everything is “on sale”. Everything is discounted. Of course, there are good deals to be had. It’s just that the effort to find and take advantage of the deal is more costly than any savings I might obtain. There is a reason why rebate forms are difficult to complete: it is in the company’s best interest that you never fill them out.

I believe in Scaling Software over Scaling People. See my blip on Techies and The Business, or the whole article here.

The most important attribute to any employee is their willingness and ability to learn. I’ve written about this one a lot. I think learning is the key to innovation, that through mistakes you get better, that Adapting is the Most Crucial Skill You’ll Ever Learn, and that progress (and who doesn’t want progress?) is an act of discovery.

So!  What are some of your beliefs?

Time Bombs

Ran across this quote recently, thought you might enjoy it:

“Don’t call your defects ‘bugs’. Call them ‘time bombs’ instead.”
- Watts S. Humphrey

From Wikipedia: “Watts S. Humphrey (born 1927) is an American software engineer, key thinker in the discipline of software engineering, and is often called the father of software quality.”

He has a recent book out that looks like it could be good, Reflections on Management: How to Manage Your Software Projects, Your Teams, Your Boss, and Yourself.  Has anyone read it?

My First iPhone App: Walk or Bus

Now Available in the iTunes App Store!!  I’m very excited about this! Never created an iPhone App before, and this was a great experience. Here’s a bit about the new app. If you try it out, please do let me know how it goes!

Do you ever wonder whether you’d be better off walking instead of taking the bus? This app will help you answer that question.

Fine tune your personal walking speed and your city’s bus speed for the most accurate Walk or Bus recommendation.

Measure by kilometers, miles, or by configurable city block sizes Receive helpful feedback: “at a brisk pace you will get there 4 minutes faster than the bus”

I’d like that feature, and that one, and that one…

Marco considers input from his users but ultimately says:

“If I let users steer product decisions, the result would be a massive codebase producing a bloated, cluttered product full of features that hardly anyone used at the expense of everyday usability and polish on the features that matter. Like Microsoft Word. Or Firefox.

By listening too much to outside suggestions, I’d destroy the very reason why I’m receiving them.”
