What Does ACN Stand For?

ACN stands for Advance Change Notice

ACN, or Advance Change Notice, is a formal communication tool used in project management and contractual environments to notify relevant stakeholders of upcoming changes to a project’s scope, schedule, or budget. The ACN outlines the nature of the change, the rationale behind it, and the anticipated impact on the project, allowing for informed decision-making and preparation ahead of the implementation. This proactive approach helps to manage expectations and minimize disruptions during the change process.
