📘 The Phoenix ProjectBy Gene Kim, Kevin Behr, and George Spafford ()

Really great book, unlike most business books I've tried to read. I recognized myself and a lot of the people and corporate structures I've worked with before in there.

Four Kinds of Work

  • Business projects
  • IT projects
  • work/change scheduling
  • unplanned work

Three Ways

p. 91

  1. Fast flow of work, what's between business and customer.
  2. Shorten and amplify feedback loops, fix quality at source, avoid rework.
  3. Create culture that fosters experimentation, learns from failure, and understands that repetition and practice lead to mastery.

Three Internal Control Objectives

  1. Gain assurance for reliability.
  2. Compliance with laws and regulations.
  3. Efficiency and effectiveness of operations.

Constraint: Resources that dictate the output of the entire system.

Work center: machine, man, method, measure (p. 209)

WIP: Work in process. Code not in production is work in process. (Code is cost!)

Time resource is busy divided by time resource is idle equals wait time. p. 213
