Flying Logic

Fast, Beautiful, and Truly Compelling Plans

If there is anything in your life, business, or organization that needs improvement? Flying Logic is a highly visual, easy to use software application that does for reasoning what spreadsheets do for numbers. Just as you would not do detailed financial projections in your head, you need Flying Logic for all nontrivial planning and reasoning endeavors.

  • Theory of Constraints (TOC) Diagrams
    • Intermediate Objectives Maps
    • Current Reality Trees
    • Future Reality Trees
    • Evaporating Clouds (Conflict Resolution Diagram)
    • Prerequisite Trees
    • Transition Trees
    • Strategy and Tactics Trees
  • Influence Diagrams
  • Causal Loop Diagrams
  • Concept Maps
  • Belief Networks
  • Flowcharts
  • ...and more!

The Flying Logic Advantage

Project management software won't help you when you have no idea what part of a complex system needs improvement, or what that improvement might look like, or how to cause that improvement. Answering these questions is a critical and often-overlooked part of the planning process, and this is where Flying Logic shines. Flying Logic diagrams are not static images— they are working models of your reasoning that you test as you build and that stay "live" as you share your reasoning with others.

Make Your Thinking Fly

Our unique, patented interface allows you to focus on what your diagram means, instead of how to lay it out. Flying Logic takes care of all the layout and formatting details: you spend your time thinking about your plan!

The Many Uses of Flying Logic

Flying Logic provides great support for a wide range of activities that demand clear and complete thinking:

  • Strategic planning
  • Competitive analysis
  • Course of Action Analysis (COA)
  • Process improvement (Six Sigma, Lean, Constraints Management)
  • Project management
  • Writing
  • Public speaking
  • Studying and teaching critical thinking
  • Life coaching
  • Personal improvement

    What They're Saying

    "Flying Logic is the best software I have ever used for writing and communicating the logic of cause and effect.”

    Dr. Oscar Morales

    "Flying Logic is a powerful tool for visual support of critical thinking. I have used the diagrams to explain the rigor behind proposed methods for solving customers' challenges and have enjoyed great feedback. I have successfully used the tool to define inter-related actions and requisite conditions required to effectively mitigate Organizational Conflict of Interest (OCI). Flying Logic elevates my ability to think visually and to rethink with minimal rework in the diagrams. It is a true enabler of constructive thought.”

    Rich Petersen
    Principal, Capridea, Inc.

    "Flying Logic makes logic visible, and removes the drudgery of making logic trees beautiful. The tools are so clever: they give you control and keep track of the analytical side invisibly.”

    James R. Holt, Ph.D., PE
    Associate Professor
    Engineering & Technology Management
    Washington State University

    "Flying Logic facilitates real-time analysis of an organization's problems in a group setting, and reduces the need for follow-up meetings to gain consensus in the planning. Flying logic is also very useful for individuals working on problems— there is less chance of overlooking negatives to an idea/solution, and this is a great improvement over current practice. Flying Logic can be used in conjunction with the tools of the Theory of Constraints to initiate a project in the most effective manner.”

    Howard D. Meeks, Ph.D.
    Associate Professor
    College of Engineering
    Iowa State University

    "Flying Logic is easy and intuitive to use. For those of us who use the TOC Thinking Processes, Flying Logic has succeeded where every other tool — whether it’s software, sticky notes, or pencil-and-paper — has failed. First, it eliminates the time spent on drawing and arranging the entities, and leaves us with more time to do the thinking! Second, it enables us to test our assumptions quickly, easily and visually.”
