Learn how to use logic models to define, design, implement, monitor, and evaluate your IT projects. Logic models are visual diagrams that show your project's logic and results.

One other caveat as you consult the flowchart: Online marketplaces such as Amazon and Walmart continue to sell discontinued Roku players, some of which have the same names as the latest models.
