Course was a good entry level discussion of WIP, but it seemed like most of the presentation was watching the instructor input data into a spreadsheet. Would have preferred a little more detail or to have this spreadsheet built out ahead of time.

It would be nice if there was more explanation of the concepts on the PDF slides and less about putting the WIP together via excel. More analysis of project positions and what it means.

The technical content was minimal. This was much more a class on basic use of Excel. I would not recommend this class.
