Rayleigh Attributes Dialog Box

The Attributes Dialog Boxis displayed after choosing theAttributesselection from theRayleigh Menu

Note: The selection of an Application Type that is not the "User Specified System" will return the PI and PM values corresponding to the Application Type. If the selection is "User Specified System" for the Application Type, the user must enter the values for the PI and PM.

Preliminary information needed for Rayleigh effort analysis is entered here. Select the Rayleigh application type. If the application type selected is user specified systemthen enter the productivity index or productivity measure. Enter the main build phase percentage. If Rayleigh is developed as a stand-alone model, enter the development schedule (months) and the source lines of code. The information which may be entered here is:

Application Type	Select any of the application types listed. If application type selected is user specified system, enter a productivity index or a productivity measure
Time to Develop (Months)	Enter a decimal value representing your estimated development schedule in months
Main Build Phase Percentage	Enter an integer value represented your estimated percent of development
Source Lines of Code	In the case of a Project, the Lines of Code will be filled in with the Source Lines of Code computed in the Function Point Model of this Project. If you are entering or modifying a stand-alone Rayleigh Model then you will enter theestimated lines of codefor the project being modeled.

Rayleigh Sensitivity Adjustments Dialog Box

TheRayleigh Sensitivity Adjustments Dialog Boxis displayed after you select theSensitivity Analysis option for theRayleigh Menu.

This dialog box allows you to specify the parameters that are used for your Rayleigh Sensitivity Analysis calculations. Select one of the following radio buttons to choose the level for entering Sensitivity Analysis adjustments to your Rayleigh Model:

SLOC	Apply adjustments to the number of source lines of code
TDEV	Apply adjustments to the time to develop (schedule)
PM	Apply adjustments to the productivity measure
PI	Apply adjustments to the productivity index

After you have chosen the adjustment level, you may enter the adjustment percentage for the Sensitivity Analysis calculations. You will be allowed to only enter a percentage for the currently chosen adjustment level. You may change the adjustment level at any time by selecting the radio button for the desired level. The adjustment percentage for a level is saved when a new level in selected.
