Summary

Allows the display of the inputs (X's). The funnel report is an important project bookkeeping tool because it 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

X-variables with information about them updated as appropriate:
  • Name
  • Status
  • Analysis and tool used

How-To

  1. Ideally, this tool is populated from the X – Input Variables section of a process map. Note: You can add unmapped variables easily without returning to the process map.
  2. As you evaluate each input, change the status from the default of potential to either eliminated or critical.
  3. If seen as beneficial for communication, enter the analysis/tool used and the result obtained (for example, p-value).
  4. Enter any appropriate conclusions in the provided Footnotes section at the bottom of the form. You can reference each note to a specific input/line using the Footnotes column.

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.
