Software development has been steered wrong by the word “requirement,” defined in the dictionary as “something mandatory or obligatory.” The word carries a connotation of absolutism and permanence, inhibitors to embracing change. And the word “requirement” is just plain wrong. Out of one thousand pages of “requirements,” if you deploy a system with the right 20% or 10% or even 5%, you will likely realize all of the business benefit envisioned for the whole system. So what were the other 80%? Not “requirements”; they weren’t really mandatory or obligatory. — Kent Beck, Extreme Programming Explained Read more →

Change Isn’t the Problem
Everything in software changes. The requirements change. The design changes. The business changes. The technology changes. The team changes. The team members change. The problem isn’t change, because change is going to happen; the problem, rather, is our inability to cope with change. — Kent Beck, Extreme Programming Explained Read more →

Happy Fathers Day!
Hi Dad! Happy Fathers Day! We didn’t spend a lot of time together but my owner says I have the heart of a much larger animal and I know I got that from you! He also says I have a “stubborn physicality” which I don’t know what that is but I know it’s good! LOL! Here’s a recent picture of me at the dog park. Well, I’m not a puppy anymore but I’m still the alpha dog of my whole neighborhood! If you’re ever in California, let’s get together! Love, Lightning Read more →

Visibility and Feedback
Forgive my ignorance. How do increased visibility and tighter feedback loops manage and reduce risk? Get in your car. Drive to a winding road. Get up to a decent speed. Close your eyes for two minutes. Then come back and ask your question again. — Ron Jeffries, Yahoo Groups (kanbandev) Read more →

Opting Out
What we need is competition and a chance for people to opt out of the system. You talk about opting out of ObamaCare? Why can’t we opt out of the whole system and take care of ourselves? — Rep. Ron Paul (R-TX) That’s a great question that I’ve wondered about for many years. For example, why can’t people opt out of Social Security? It seems to be in pretty bad shape. Why can’t I say to the government, “Do not take any Social Security deductions from my income. Let me keep all that money, and when I retire, you owe me nothing.” Why is that not an option? You might say, “Because you’ll screw it up. You’ll spend all the money now, and when you’re too old to work, you won’t have anything in the bank.” Why is that your problem? Read more →
