There are a flood of reports being proliferated throughout the organization. Who knows what they are used for. And now the "On-Time Cases" KPI means something different to each department.
Hearing this within your organization? This could be a problem from lack of best practices and governance.
The use of "Content Clusters" for corporate reporting, as Aloys Hosman writes, is an approach to clearly define your governance rules, which could save your organization from this mess.
This technique, among many things, lays out who is responsible for meta data within centrally managed data warehouses -- The Gatekeepers. It is less about ownership of the actual data; instead the discussion is focused on ownership of the metadata.
What I would add is the suggestion of not to detail out the entire governance rulebook at the beginning. See what works for your organization; monitor the process and make improvements. The key is to continuously improve so you don't have to create the perfect end-state at the start.
