📘 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
- Fast flow of work, what's between business and customer.
- Shorten and amplify feedback loops, fix quality at source, avoid rework.
- Create culture that fosters experimentation, learns from failure, and understands that repetition and practice lead to mastery.
Three Internal Control Objectives
- Gain assurance for reliability.
- Compliance with laws and regulations.
- 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
