Engineering Management – The Missing Manual (Dave Rensin)

Engineering leaders must build models, prioritize transparency, and manage uncertainty to create a culture of decision-making and growth, rather than control and anxiety.

Key takeaways
  • Our brains are wired to build models, and that’s not going to change.
  • Models don’t need to be perfect, just predictive and cheap to do inference.
  • All models are wrong, including the ones in your brain.
  • We need to be transparent about decision-making and reasoning behind them.
  • Humans need agency, and central control is not a good way to achieve it.
  • Uncertainty about the future is what causes anxiety.
  • We need to articulate principles and objectives to remove anxiety.
  • We should teach people how we will make decisions, not what decisions to make.
  • Leadership is about creating certainty and removing anxiety.
  • Good leaders are those who can build models, reason abstractly, and make decisions.
  • We should focus on uncertainty about the future, not control.
  • Certification should not be the goal, but rather creating value.
  • Humans are not computers, and our decisions are not always rational.
  • Our brains use glucose and cortisol, which increase with anxiety.
  • Anxiety causes stress, and stress affects our ability to think rationally.
  • Leadership is about creating an environment where people can build models and make decisions.
  • People want to be good leaders, not just successful.
  • A model that’s not cheap to do inference is not a good model.
  • Leadership should be about creating a culture where people can learn and grow.
  • The brain is a large and complex system, and we should not assume we understand it fully.
