During PR14 and PR19 we have supported Thames Water in developing its draft and final business plans. This involved a number of elements:
 

• Development of the Service Risk Framework of service KPIs by which all investments are appraised and which link to their outcomes framework

​

• The provision and configuration of decision support tools, including the asset optimisation tool AIM and the cross-asset optimisation tool APS

​

• Detailed modelling of water and wastewater infrastructure assets and incorporation into AIM for asset level scenario analysis

​

• Support on cross asset optimisation in APS

​

• Customer engagement around customer willingness to pay, triangulation, resilience, performance commitments and outcome delivery incentives

​

• Discussions with stakeholders on the findings of customer research and the impact on the business plan
