The Challenge

  • The studies, to determine value to shareholders of the Stage II projects, were to be completed to industry standards from a standing start with little preparatory work
  • Maintaining focus on this objective, tight definition of scope, and avoiding diversions into alternatives
  • Meet the immovable study completion date
  • Calculate shareholder returns from the necessary capital investment with defined confidence levels

The Outcome

  • Engineering deliverables sufficient to calculate the value to shareholders of the projects, and no more
  • Over-engineering, common in studies, was avoided
  • Shareholder value calculation of necessary accuracy from fully developed capital estimate and delivery schedule
  • Project Implementation Plans to facilitate launch immediately upon Shareholder approval were conceived and documented
  • Assignment completed on time and under budget
