    • CONCLUSIONSConclusions of this Report • The original Deterministic Schedule is “aggressive but achievable” provided no slippage occurs in Approvals Process and Project Sanction is not delayed beyond July 2008 • EPCI LL Procurement manageable with a schedule benefit and slight cost risk ahead of Project Sanction • Much effort has gone into ensuring that “team effort” at 2 x risk workshops contributed to refinement both of quality, content and appropriate detail of Risk Registers • A “face-to-face” knowledge management process was adopted to refine accuracy of schedule 3 point activity duration estimates – this proved a valuable exercise and encouraged risk “ownership” • Using a structured Risk Assessment Process and latest risk analysis methodologies applied to state of the art Risk Analysis software the consultant was able to : • Link Qualitative Risk Registers to Level 2 Schedule activities • Run probabilistic algorithms on Quantitative 3 point duration estimates and Class 2 Estimate • Risk Analysis / Outputs • Schedule : Monte-Carlo Simulation in PERTMASTER ( “Base Case” assumes Sanction Jul 08”) • P10 = 25th May 2010 (originally the P50 Deterministic Case) • P50 = 7th July 2010 • P90 = 26th August 2010 • Schedule : Monte-Carlo Simulation PERTMASTER (“Sanction Delay Case” assumes Sep 08”) • P10 = 5th Oct 2010 • P50 = 4th Nov 2010 • P90 = 6th Dec 2010
