Technology in the Cockpit for Navs

Wondering who, if anyone, has formalized SOPs, Guidelines, Protocols, Rules, (I care not what they are called), for effectively maximising the integration of “pen and paper mapping” and the use of “tablets’ by navigators in the cockpit. Specifically how and what is the tablet used for …. does it actually supercede and/or replace any of the disciplines associated with mapping. Is it merely a comfort tool. Happy to hear your experiences directly @ especially if you can share any documentation. Thanks.
