Definition of common language
The aim is to create a "Single Source of Truth" for the FinOps lexicon within the organization.
In particular, the common terminologies and categorizations to be used in the model will be defined, based, for example, on the [Technical Business Management] taxonomy (https://www.tbmcouncil.org/) covered by Apptio in its [TBM Unified Model (ATUM)] (https://www.apptio.com/fr/company/technology-business-management/).
Once everyone uses the same terminologies, it is also necessary to define standard KPIs common to all applications and Business Units, while not forgetting to ask the right questions in order to avoid excesses that will be counterproductive:
And in the same way that one would prefer to use common KPIs across the organization, one would prefer to define standard reporting templates to make it easier for everyone to understand and compare.
