“Competence, like truth, beauty, and contact lenses, is in the eye of the beholder” Dr. Laurence J Peter
Automation Federation has done fantastic work on competency required in Automation.
A must for every hiring manager to prepare job profile and for every Automation Professional to evaluate his skills and compare with this one for self development.
Another great resource is from ISA which describes various domains in Automation and explains knowledge and Skill set required.
Finally, I would like to quote Charlie Munger, “You’ve got to hang experience on a latticework of models in your head”. Because then only we learn an apply all the theory.
Keep learning, keep applying and keep succeeding …
