0-100 Earned Value Method: Benefits and Best Practices

Introduction to the 0-100 Earned Value Method

The 0-100 earned value method (EVM) should be implemented at the lowest level possible, as Ruskin (2004) advocates, because it prevents individuals from attempting to "game the system," to "look good," or to falsify their actual progress. Such misrepresentation is more likely to occur with a 50-50 approach, where the individual or team receives credit simply for beginning a task. With the 0-100 approach, no credit is received until completion and passing the EVM assessment (Earned Value Analysis, 2012).

Even with quarterly approaches, EVMs can become somewhat meaningless, trivial, or simply viewed as overbearingly bureaucratic. There is a sense that too much micro-management is occurring, which can grate on individuals and teams who prefer a degree of independence, responsibility, and autonomy.

Accountability and Autonomy Under the 0-100 Approach

From this perspective, the 0-100 method also promotes responsibility because the work is not assessed until it is completed, leaving it in the hands of the workers throughout the entire process. This approach instills a feeling of trust and ensures a proper proportion of accountability at the end. Rather than subjecting workers to continuous checkpoints that can feel intrusive, the method grants them the space to work according to their own judgment and expertise.

Addressing the Risk of Late Error Detection

An argument against the 0-100 method is that by waiting until the end to perform the EVM, there is a risk of failing to catch mistakes early — mistakes that could have been corrected before triggering a chain of consequential errors. Against this argument, Ruskin (2004) asserts that the 0-100 approach can actually catch such early mistakes by being implemented at the earliest stages of work possible.

In other words, the Work Breakdown Structure (WBS) should be organized so that the early stages — which are, in a sense, the most important because they lay the foundation for a project and determine its overall direction — are reviewed almost immediately. Rather than dividing work into fixed percentage stages (whether 50-50 or 25/25/25/25), the WBS is structured so that the early integral steps are identified as single unit building blocks, with tasks budgeted appropriately and kept simple.

WBS Structuring and Early-Stage Evaluation

Just as early schoolwork tends to be easiest and shortest, growing more complex and demanding as the year progresses, this approach applies the same logic: early work is divided into smaller units to allow for correction on a 0-100 basis. Essentially, it is a pass-fail system throughout, with more frequent evaluations performed at the beginning to ensure the project starts on the right footing. As the project advances, the units grow longer and more complex, reflecting the increasing depth of the work.

Conclusion

With the 0-100 method, the WBS is guaranteed to get off to a good start, provided that the early stages are structured as unit building blocks that can be checked off by the EVM as they are accomplished and the foundation set for a successful project. As the project progresses, the units should grow longer, reflecting the deeper complexity of later-stage work. This approach balances accountability with autonomy, ensuring that project management serves both organizational goals and the well-being of the workers responsible for achieving them.
