Diego Hernández completed this course, spending 3 hours a week on it and found the course difficulty to be medium.
It presents a model called JAFAR, which helps to analyze the skills required for a job, find benchmarks to measure proficiency on those skills, recollect evidence, assessed them and obtaining a score. The model was encapsulated in a Excel spreadsheet with macros, that generate a summary of the data gathered.
I think the most valuable thing about this course is the model itself and the methodology followed for establish a concrete analysis of skills. The goal of this analysis is to help as a compass for career growth.
