Updating RGA Spreadsheets and Reports from Prior Versions

For reliability growth data analysis only.

In versions prior to Version 2020, RGA was a separate desktop application that included both specialized functions for reliability growth analyses as well as modified versions of functions that are also used in Weibull++. While most of the functions in Version 2020 and later work the same, there are some changes that you will need to make before using a general spreadsheet or ReliaSoft Workbook that you created in an earlier version.

New Functions

The following RGA-specific functions have new names in Version 2020 as the names used in older versions are now specific for life data and life-stress data folios.

Data Sheet References

In prior versions, data sheet references looked like this:

In Version 2020, you must update the data sheet references to include the folder name, like this:

=MODEL("RGA!Folio1!Data1")

Data sources that are associated with ReliaSoft Workbooks do not have to be manually updated.

Plots

All reliability growth plots created in the Word Processing Module must be recreated.
