Abstract: Different forensic schedule delay methodologies identify delays to the critical path in different ways: similar to Metric and English systems that can both measure distance but do so using different units. Some experts combine two or more delay methodologies in a single analysis to generate a specific result. Akin to combining meters and yards into a single measurement of units even though they are different distances. This paper will identify the situations where using two or more methodologies in a single analysis makes sense or is necessary, and where combining methodologies generates misleading and inaccurate results. The understanding of how different methodologies measure forensic delay differently is a vital component of this discussion, and this paper will explore current understanding of this issue.
