To those unfamiliar with EVM, it might appear that this project was over budget through week 4 and then under budget from week 6 through week.
The original concept was called pert/cost, but it was considered overly burdensome (not very adaptable) by contractors whom were mandated to use it, and many variations of it began to proliferate among various procurement programs.
