Rather, it may be more related to the procedures your organization is willing to implement to make EVM work in a small environment. We quickly implemented some stronger contractual language stating that before starting a mini-task, boundaries must be setup. This boundaries included the estimated number of labor months expected to be required, along with what the deliverable would be. FYI - each task could be anywhere from 2 weeks to six months. And better yet, the Contractor applied basic EVM concepts to our boundaries.
Any advice is welcomed.
