Personal Guidelines

Hard to reduce myself to a bullet-point list, but here we go:

  • Be Passionate. Be Curios. Have Fun.
  • Technology is NOT a solution by itself
  • Cause => Effect
  • Results are important
  • Agility = Discipline != Chaos
  • Embrace Change
  • Embrace Failure
  • Technology < Process < People

Special-Interest: Software Evolution

The core challenge of building Systems is coping with change and failure. Getting out version 1.0 can be tough, but the “real magic and skill” is shown on how you keep up with next requirements or influences when the baby is out the door. This Software Evolution aspect is happening on many areas/levels: team/company-organization, external stakeholders, growing usage of system, legacy technology, refactorings, system-build/deployment, introducing risk by changing your system… you name it. All these bigger-picture success-factors teach me new lessons everyday.
