The more people I talk to about my plans for leaving IBM and experimenting with business, the more real the idea becomes. The more excited and confident I get about it, too, which is a good sign.

Today I sent my formal resignation e-mail, the one that kicks off all the associated HR processes. I named February 17 as my date: four years, four months, and two days after I joined IBM.

I expect to feel more nostalgia as the date approaches, and perhaps uncertainty. That’s all normal, which is why I’m brainstorming and writing down my reasons. The notes will come in handy if I hit a slump. It looks like all systems are go, though. It’s clearly a good idea for me at this point in time.

I’ve found people to take over all of my extracurricular interests. I’ve been braindumping enough throughout my time at IBM to not worry as much about transitions. I’ve always worked on things with the lottery/bus factor in mind: would the project be endangered if I won the lottery or got hit by a bus? (The lottery is highly unlikely, since I don’t buy tickets; I usually look both ways when crossing the street, but one never knows what could happen in the streets of Toronto.) I’ve written lots of notes and shared as much as I could as publicly as I could, and now it’s easy to link things together in a knowledge map on a wiki page that people can even update after I’m gone.

My manager told me of ways back in, and contracting companies that IBM is used to working with. It might be an option. I’d like to spend some time up front seeing if I can develop a business. Freelancing sounds like a reliable alternative, but it’s similar enough to what I currently do at IBM that I think I would learn lots more from trying to build a proper sustainable business with compounding value.

One step at a time. The project that I’m working on looks decent in IE8, IE9, Firefox, and Safari, and it looks a heck of a lot better than it did when I took it over. I’m on track to wrap that up well. Then there’s some HR paperwork to take care of, and more braindumping of memories and thoughts before they fade into fuzziness. Then the transition! Then slowly easing into experiments and feedback cycles and little bets…
