Hold meetings with your key stakeholders and stakeholder groups to understand how the assets in the inventory are used, their business value and business risk. By identifying the value and risk of the information assets at the strategic and business area levels, you will have segmented levels of materiality of your assets. You also need to decide how many trust levels you should have in your trust model. To do this, examine the lineage and curation metadata relating to different asset types and differing levels of materiality, and then pragmatically determine how many levels of trust you need. Less than five will not support sensitivity in governance decision making, and more than 10 may make the trust levels too nuanced to be useful. Applying the trust model to your inventory of assets will help you decide where to target investment on asset improvement, and help to identify the decision areas that will benefit as a result.
