Dan and Tim will introduce decision science tools and frameworks and use case studies to illustrate how adoption of decision science tools combined with project management processes can be employed to optimize remediation portfolios. Case studies will illustrate how teams can shape projects and portfolios that achieve multiple owner, regulator, stakeholder and rights holder objectives, while also saving time, money, effort and better managing project risks. A case study will illustrate how portfolios can be developed to align with organizational strategies and provide a framework to estimate environmental liability discharge per dollar invested. Learning resources and links will be shared.
