A company uses an organization in AWS Organizations to manage the company's AWS accounts. The company uses AWS CloudFormation to deploy all infrastructure. A finance team wants to build a chargeback model. The finance team asked each business unit to tag resources by using a predefined list of project values. When the finance team used the AWS Cost and Usage Report in AWS Cost Explorer and filtered based on project, the team noticed noncompliant project values. The company wants to enforce the use of project tags for new resources. Which solution will meet these requirements with the LEAST effort?
