Use the Funnel Report to track which inputs are critical, eliminated, or not yet evaluated. A funnel report lists the following information:
  • Variables of interest
  • Whether the variables are vital to the process (the critical inputs), have no significant effect relative to the project goals (the eliminated inputs), or have not yet been evaluated (the potential inputs)
  • Tools and results of the evaluation to determine the status of the variables (critical, eliminated, or potential)
Answers the questions:
  • What are the potential inputs?
  • What are the critical inputs?
  • What is the rationale for calling an input critical or eliminated?
When to Use Purpose
Early in the project Define all the inputs that could potentially affect the process.
Mid-project Keep track of which variables have been eliminated from consideration, which have been found critical, and which still need to be evaluated.
Mid-project Provide a list of the inputs that must be addressed in the Improve and Control phases.

Data

Your data must be x variables that are updated with the following information:
  • Name
  • Status
  • Analysis and tool used

Guidelines

  • This is a bookkeeping tool used to ensure you account for all potential inputs.
  • You do not need all inputs listed. If you are presenting the final list of critical inputs, just show the critical inputs.

How-to

  1. Ideally, you populate the funnel table with x variables that already exist on a process map. However, you can add new unmapped variables without returning to the process map.
  2. As you evaluate each input, change the status from the default of Potential to either Critical or Eliminated.
  3. If it benefits communication, enter the analysis/tool used and the result obtained, for example, the p-value.
  4. Enter any appropriate conclusions or footnotes.
