The cost of operating this way is enormous and almost completely invisible. Decisions take longer because they require more triangulation. Conflicts that should be substantive become procedural, with people arguing about whose numbers are right instead of what to do. Strategic plans get written in language vague enough to survive contact with bad data, which means the plans don't actually drive execution. Capital allocation suffers because nobody is confident enough in the underlying analysis to push for the bold move. The organization performs well below its strategic ceiling, and leadership attributes the underperformance to execution issues, market conditions, or talent gaps. The actual cause is upstream of all of it. The organization is operating without a shared, reliable source of financial truth, and the consequences ripple through everything downstream.
