Sharpen the Saw

“If I had eight hours to chop down a tree, I'd spend six sharpening my axe.”

- Abraham Lincoln

Without appreciation for true expertise...

20th Century: Industrial Efficiency

Frederick Winslow Taylor

The Peter Principle

Employees within an organizationwill advance to their

highest level of competence and then

be promoted to and remain at a level which

they are incompetent.

The Dilbert Principle

The most ineffective workers are systematically moved

to the place where they can do the least damage –

Management.

The Peter Principle

Employees within an organizationwill advance to their

highest level of competence and then

be promoted to and remain at a level which

they are incompetent – Management.

IMHO, companies that do not offer dedicated development career tracks

and/or force engineers to be managers are doomed to fail.

Dunning-Kruger effect

Where unskilled individuals suffer from illusory superiority, mistakenly rating their ability much higher than average...

TL; DR:

Most of your "Sirs" and "Masters" don't even deserve those titles.

Stop inflating their egos.

Thank you for listening!

Experts work from intuition

Proficient practitioners can self-correct

Competents can troubleshoot

ABs don't want the big picture

Novices need recipes
