During the course of a project we often uncover opportunities to make improvements to things that are out of scope. In projects there is a negative stigma to diverging from scope; it's even given the awful name "scope creep". Scope discipline is of course important to stay within boundaries, but if my mechanic finds something else wrong under the hood of my car during an oil change, I at least want to know about it.
Follow-On Action Recommendations (FOARs) are gold to an organization receptive to future benefit opportunities since they typically come with insight not otherwise available during status quo operations. In fact FOARs are so valuable they should be reviewed by the Project Board regularly during the project since they could legitimately change the scope of the project for the better.
