Effectiveness Factors for Multi-Phase Data

Like the effectiveness factors for the Crow Extended model, analysis with the Crow Extended – Continuous Evaluation model may also require you to specify the decrease in failure intensity for some delayed fixes. However, in the continuous evaluation model, a specified effectiveness factor is required only if the delayed fix time (I event) is not recorded in the data set. (If the fix time is provided, the model can use the data to evaluate the effectiveness of those fixes.)

To specify the required effectiveness factors, choose Growth Data > Crow Extended > Effectiveness Factors or click the icon on the control panel.

In a multi-phase data sheet, the Effectiveness Factors window will display one or both of the following sheets.

BD Modes Sheet

The BD Modes sheet is always displayed and it shows a list of any BD failure modes in the current data set that do not have a specific fix time (I event) recorded in the data set. For each failure mode in the list:

Implemented Fixes Sheet

If you have selected the Allow EF values for BD modes with implemented fixes option on the Calculations page of the Application Setup, the Implemented Fixes sheet will show a list of the BD failure modes in the current data set that do have a specific fix time (I event) recorded. This sheet is for your information only. Any inputs you provide here will not affect the calculations.
