Despite laudable case-by-case efforts, there is no comprehensive or systematic method for tracking and measuring interoperability. ISIS is investigating methods for tracking and measuring the costs and risks associated with interoperable systems of systems. Some approaches are described below.

• Measuring Systems Interoperability: Challenges and Opportunities presents best practices for measuring systems interoperability and assisting military planners in the acquisition, development, and implementation of command and control systems that are interoperable.
• Revealing Cost Drivers for Systems Integration and Interoperability outlines a major research effort undertaken by the DoD, SEI and the University of North Carolina to identify the non-SLOC based cost drivers of systems integration and interoperability.
• The results of a Q Methodology study of public sector CIO's suggest that Q Methodology may prove helpful in isolating non-technical latent costs of system integration and interoperability.
• The Acquisition of Joint Programs: The Implications of Interdependencies describes he results of a comparison of single and joint acquisition efforts.
