A. Levels 1 and 2. I ship stuff when it's as excellent and finished as I can possibly make it.
B. Levels 3 and 4. I'm too busy to get every last detail tidied up, but when I ship stuff, it's 90% of what I wanted it to be. I don't always nail the deadline 100%, but on both quality and timeliness, I'm respected and seen as someone who doesn't let the team down. I secretly like peeling away when it's almost done, because there's usually something more valuable and exciting coming next.
C. Level 5. I'm very erratic. On a few key projects, I'm still shipping in a pretty dependable way. But the amount of half-done stuff in my mental attic is scary. I've still got the willpower and credibility every now and then to offload/kill the most hopeless projects, and that gives me a bit of a reprieve.
D. Levels 6 and 7. I don't have a coherent approach to shipping. Incomplete work leaves my control when someone else seizes it from me. There's a ton of stuff that's half-done that I may never have time to revisit. I'm too tired to sort out anything -- or put up a fight.
