  * “Read 500 pages like this every day,” Buffett said to the students, while reaching toward a stack of manuals and papers. “That’s how knowledge works. It builds up, like compound interest. All of you can do it, but I guarantee not many of you will do it.”
  * "The performance of the whole is never the sum of the performance of the parts taken separately, but it's the product of their interactions" -- Russell Ackoff

  * "Often people want to devise formulas based on the output of various tools for scoring. It’s an understandable inclination. However, value is hard to measure. It is better to form a subjective judgment leading to a score. This lets us give weight to dimensions of value that rely on many forms of evidence, including just a felt sense of value." from [[https://communications.globant.com/public/wp/system-renewal-patterns/White_Paper-Patterns_of_Systems_Renewal-v4.pdf|"Patterns of Systems Renewal"]] by Michael Feathers but generally applicable.
