Change management is an inevitable part in the engineering management of engineering projects so effective change management is critical to determine if the proposed changes add economic value to the project. The marginal cost methodology is proposed to effectively manage change and to parse the changes only to those which add economic value. The marginal cost methodology is valuable in engineering decision making and also facilitates statistical analysis in trade studies for applications to future projects.
