Tip #5 | Don't provide "percentage confident" estimates (especially "90% confident") unless you have a quantitatively derived basis for doing so. |
Tip #6 | Avoid using artificially narrow ranges. Be sure the ranges you use in your estimates don't misrepresent your confidence in your estimates. |
Tip #7 | If you are feeling pressure to make your ranges narrower, verify that the pressure actually is coming from an external source and not from yourself. |
