Hello Andrew ,
It would be great if you could mention if there is anything specific that you are wanting to know.
Otherwise , generally speaking , Successfactors workbooks are specific for individual modules in SuccessFactors like you have a standard template defined for Recruitment Module or Onboarding.
These are required to document the customer requirements in a standardized format for each module. The implementation consultants generally guide the customers on how to fill these and then get a sign-off to begin the configuration kick off.
Once the configurations are completed , the following iterations are held and the respective changes required are tracked in the same workbook itself and then customer sign-offs are obtained with each iteration before beginning the configuration changes.
Let me know if this helps!
Thanks & Regards ,
