Open Acquisition System Concurrent Contract Modification White Paper

nGAP submitted a technical white paper to the Naval Post Graduate Schools's Annual Acquisition Research Symposium. The topic discusses the merits, approaches, and design philosophy of optimizing contract modifications for Naval Maintenance, Repair, and Overhaul contracting in the US Navy.

Concurrent Modifications, The Act of Optimizing Multiple Contract Changes Under One Universal Modification in the Acquisition, Maintenance, and Program Management of Large Military Sea, Land, and Air Platforms

This paper looks into the process known as concurrent contract modification (CCM) and proposes a solution to automate it. While CCMs are not inherently disallowed, they do present contract logistical and administrative problems.

The larger projects become, the more difficult it is to track, administer, and document proposed changes. Without an efficient means toward managing incoming changes, gaining any tangible and accurate reporting on project outcomes proves significantly challenging if not impossible.

What this paper proposes is a new approach to contract change management utilizing a software tool designed for ground-level operations that scale up to Contract and Program responsible stakeholders.

Instead of relying on the output of contract writing systems, this system can be used to manage the execution of several related contracts under a single project with shared sources of funding. Focusing on automated infrastructure and a process for contract change management will allow for greater insight and accountability at program execution levels, in the case of the Navy, at the Regional Maintenance Center or Shipyard level.
