Three rules to make decisions like a boss.

  • Rule #1: Make quick decisions. It’s better to be 40% of the times wrong than 90% of the times undecided.
  • Rule #2: Overcome the temptation to stick to yesterday’s wrong decision just to look more consistent. Nobody hired you for consistency, but people will fire you for sticking to wrong decisions.
  • Rule #3: Accept that other people around you follow rule #1. If smart people reject your idea, it doesn’t mean it’s a bad idea.

S.M.A.R.T.

Ideally speaking, each corporate, department, and section objective should be:

  • Specific – target a specific area for improvement.
  • Measurable – quantify or at least suggest an indicator of progress.
  • Assignable – specify who will do it.
  • Realistic – state what results can realistically be achieved, given available resources.
  • Time-related – specify when the result(s) can be achieved.

Object-Oriented vs. Procedural-Oriented

Procedural code gets information then makes decisions. Object-oriented code tells objects to do things.
