7. What is our scope? • The key functions that were identified that will help define our scope were: • Capital planning – how capital budgets are assembled, and project plans for planned maintenance developed and executed • Execution of work – which we hope and expect will very largely re-use large sections of the Reactive Repairs work • Compliance – specifically dealing with the regulatorily required aggregations and reporting • Analytics – including building intelligent modeling of specific asset expected life time, and using reactive repairs data to predict tipping points that trigger planned replacement programs • Assessments – fire risk assessments (FRA), water health etc. as well as surveys in so far as they are part of planned maintenance processes or may lead to the need for a planned maintenance program, for example condition assessments (e.g. roof survey) but excluding, for example, void surveys • Data migration – either during stick transfers, mergers and acquisitions or – acknowledging that the assets will typically out live the software that stores the data – migration of asset data from one system to another • In addition, the following potential areas for data models were identified: • Asset typology – a classification that standardizes the level of granularity of “asset” (e.g. ‘bathroom’ or ‘washer in tap’), and ties in with development handover and building information models (BIM) • Asset inventory – standard model for an inventory to make it easier to share with service providers, mine for analytics and to migrate between organizations and systems

8. Agreed Use Cases and scope In scope: Program of work instruction (data exchange) Program of work (data model) Asset – including lifecycle (data model) Certification (data model) Data migration In scope, but only if simple: EPC/SAP rating detail (data model) Component accounting Customer satisfaction

9. Use cases confirmed in scope c.f. Reactive Repairs process map and use cases (see previously and next slide)

14. Use cases in scope if simple The following use cases were considered to be relatively simple, and on that basis retained in scope. If, however, they turn out to contain unanticipated complexity they will be deferred.
