Why Early Assumptions Drive Project Outcomes More Than Execution | ROMAN Consulting Group
Most capital project overruns are not created during execution. They are locked in during front-end planning, when scope is still forming, uncertainty is high, and early assumptions shape cost, schedule, and risk outcomes. By the time a project reaches sanction, much of the total cost is already committed, leaving limited ability to influence results.
The underlying issue is often cognitive bias. Optimism, anchoring, groupthink, and confirmation bias influence how teams interpret data, set estimates, and evaluate risks. These biases rarely appear obvious. Instead, they are embedded in everyday decisions and often masked by variation across contributors, making systematic underestimation difficult to detect.
Cost Influence Curve: The ability to influence project cost declines rapidly from FEL-1 to FEL-3 while capital commitment increases, meaning early decisions have the greatest impact on final outcomes.
Bias vs Noise in Estimating: Systematic bias can be hidden by variation across teams, making inaccurate estimates appear balanced when underlying assumptions are misaligned.
Reducing front-end planning bias requires structure and discipline:
Aligning estimate accuracy with actual scope maturity and estimate classification
Using tools such as PDRI to measure scope definition objectively
Starting risk analysis early in FEL-1 to quantify uncertainty before estimates are fixed
Applying independent estimate reviews to challenge internal assumptions
Creating structured environments where dissent and alternative views are encouraged
Managing project bias is not optional. It is a governance discipline that directly impacts cost certainty and investment outcomes.
At ROMAN Consulting Group, we help owners and project teams reduce front-end planning bias through independent estimate reviews, scope maturity assessments, and structured risk analysis. Our approach brings objectivity and discipline to early project decisions, helping organizations make stronger investment decisions before cost and risk are locked in.
