General query regarding record of design decisions

[aramalla divya]

Hi

Can any one help with my below query

'Where should design decisions that ultimately affect the end user(Maintainer) be recorded?"

Depends on the project of course, but I'd say the Design Log.  However rather than just record, you may need to seek information, offer options etc and therefore a RFI(Request Fot Information) or a TQ (Technical Query) might be appropriate.  Often it is better to engage early by informal discussion, rather than risk the design being rejected later on.  
However if there is a residual hazard which it has not been practicable for the design to control sufficiently and an onus is being placed on the user/ maintainer of the system, then obviously it would be recorded in the Hazard Log and then there may be a range of actions, one of which is likely to be an appropriate entry in the O&M (Operations and Maintenance) manual.

Thank You for the quick response
