Managing vendors is one thing. Managing the cost of managing them is another. This two-part white paper series examines governance density, the hidden overhead that accumulates when vendor oversight grows faster than the value it generates. Part one introduces a diagnostic framework and the Governance Density Index to help mid-market organizations measure and locate the problem. Part two presents a structured redesign approach, including tiering principles, stakeholder alignment strategies, and a 90-day implementation plan to recover margin without exiting contracts or restructuring teams.
