IBMs can only be credited for activities that have been ongoing - they are not for one-offs or planned initiatives in the future. As such, you should be able to produce three areas of proof to demonstrate the presence of an IBM.
- Last Year's Financials. Showing total revenue and a breakdown of the revenue streams against which the IBM applies.
- Information on the beneficial product/service itself. eg studies, research, certificates etc.
- Evidence of outcomes. This applies if the outcomes are being identified and tracked or analysed.
