A Logic Model is a systematic, visual way to present a summarized understanding of a project and  how it works.

At their core, logic models identify the project logic. They help teams articulate the desired long-term change and map out what needs to happen for that change to be achieved. However, in practice, logic models do much more.

The information contained in logic models is used by many stakeholders for multiple purposes, check out on the images some o the uses!

• Project proposal writers: Use logic models to prompt discussions about potential activities,
  resource estimates, calendars and risk management.
• Project managers: Use logic models to communicate with stakeholders (communities, partners and others) to explain what the project will accomplish, and how.
• Business development staff: Use logic models to explain the project logic and results to potential funders.
• Project teams: Revisit logic models during project implementation, updating strategies and processes as they learn from experience, and adapt to unforeseen events. 
• MEAL teams: Use logic models as principle input of the design of MEAL systems

Each logic model (ToC, RF, Logframe) draws and builds on the information found in the previous tools.
For this reason, it is best to create them in sequence. Figure 6 explores each of the three logic model tools, identifying the core content of each and comparing the purpose of each.
