This white paper explores the concept of value leakage and the importance of operational readiness in maximising the value of a project. Value leakage occurs when the estimated net present value of a project is reduced over time due to actions or inactions by stakeholders. To unlock operational excellence, organisations must focus on three key parameters – people, processes and systems. Lessons from previous experiences highlight the importance of operational readiness planning, clear accountability and ownership, uniqueness factors, team integration, toplevel structure, ramp-up plans as well as operational reporting and control. By prioritising operational readiness and implementing effective strategies, organisations can prevent value leakage, maximise project success and achieve operational excellence.
