Delay Is Not Always Waste: Specifications in a Lean Organization

Key Takeaways:

  • Specifications are always waste - some are necessary waste.
  • We can minimize unnecessary waste in our specs by breaking them down, making them easy to use, making them visible and easy to change.
  • In a lean product development organization, the specs and the product design emerge together during early product development.

Knowledge Driven Design Reviews: How to Focus Design Reviews to Maximize Knowledge Creation

Key Takeaways:

  • Design Reviews are some of the best opportunities to grow and share knowledge, when we get mandatory checks and bureaucratic processes out of the way.
  • The person whose work will be reviewed is the person who should set the agenda.
  • Feedback in a Design Review is most effective when it’s given in the form of challenging questions rather than direct advice.

Integration Events: Pull Your Product Design Together

Key Takeaways:

  • Integration Events pull work through product development and help teams identify integration problems early.
  • Integration Plans line out the integration events and team expectations.
  • Integration Events require advance preparation, a format that allows for a lot of interaction and attention to detail, and the ability to “go and see” when the team finds problems.

Eliminate the Weak: How Probing for Weaknesses Leads to Better Design Decisions in SBCE

Key Takeaways:

  • We get the best results from convergence processes like SBCE when we eliminate weak alternatives instead of selecting winners.
  • Convergence tests that probe for weaknesses are more likely to find problems that could cause design loopbacks later in development.
  • Decision tables can help a team eliminate alternatives that are clearly not worth any investment - but they cannot substitute for a convergent decision-making process.

How to Build a Trade-Off Curve

Key Takeaways:

  • Trade-off curves organize product design data into reusable knowledge.
  • Data for trade-off curves can come from mathematical analysis, product design data, simulations and physical experiments.
  • Trade-off curves must be understandable, believable and actionable to be reused.
