KPI definition for cladding and cementing validation

Summary
To ensure a successful well design, KPIs related to cladding and cementing performance will be formalised with the assistance of the advisory board. This will be a live document, updated as the project progresses and new KPIs added if required. These KPIs will be used to validate the cladding and cement solutions in a credible scientific manner for work in WP3 and WP4 along with validation activities in WP6.
