Steve, its been around for a while and was kind of inevitable. EV measures differences and ratios on the vertical axis and it was just a matter of time before someone measured differences and ratios horizontally.
It still ignores CPM and has other similar flaws as EV.
Wow! Something new! Thanks, Barry and Darren!
Im trying to digest it. Im still concerned (as I mentioned WRT SPI in the other thread) that it ignores the most important element of schedule theory, i.e., the CP. But maybe that can be adjusted also by putting the milestomes on the ALAP dates, as with SPI.
I look forward to discussing this further when I understand it better.

Yayan / R. Catalan,
Reading through both of your posts and forgive me if I’ve got the wrong end of the stick. I don’t think Barry wants to know about Earned Value per se, but rather Earned Schedule.
Earned Schedule
Traditionally Earned Value measures schedule performance as a cost, not in units of time. It also has an idiosyncratic tendency to show perfect schedule performance at the end of the project or if the project slips past its baseline end date.
Earned Schedule is supposedly the next step on from Earned Value as you can apply equivalent formulae and measure schedule performance in units of time and enhance your Earned Value reporting.
I’m yet to be convinced of its value (pardon the pun), however, that’s probably more to do with my limited understand of the subject. Perhaps I’m labouring under a misapprehension, but if I wanted to predict an end date for the project, I would be more inclined to utilise a Gantt chart and precedence network.
Regards,
Darren
