From the Document: "The following guidance should be used to develop a Implementation & Measurement Plan (IMP). This plan will assist you in planning the implementation of your project and how you will measure its outcomes. Additionally, you will use this plan template to report progress against implementation milestones and report outcome data to DHS on a quarterly basis. In accordance with 2 CFR [Code of Federal Regulations] 200.328 significant developments should be reported in between reporting periods, and this plan may be utilized as well to do so."
