An organization should have a well-developed logic model in place before they finalize a comprehensive outcome measurement plan. A logic model maps out an overview of an organization's tools and resources, the services they provide, and the intended impacts of these services. A basic logic model documents inputs or resources, activities, outputs, and short-term, intermediate, and long-term outcomes. Inputs or resources are the assets that an organization is prepared to invest to support or implement a program, including things like money, staff, and equipment. Activities capture the methodologies an organization plans to use in order to implement a project, while outputs describe activities in more finite, numerical terms such as the units of service provided. Lastly, outcomes capture the changes, benefits, and overall impact that the program or initiative has had on an organization's client population. Once a well-developed logic model is in place, an organization can begin to identify performance indicators that will help to measure the organization's progress towards its intended outcomes.
