The most practical version keeps SharePoint as the place where approved procedure documents live and lets the procedure tool pull from it, so a new or updated document in SharePoint can be picked up, converted into steps and sent for review. Operators then run the digital version, while SharePoint stays the document library people are used to.
The important details are which library and folders are in scope, how approval status is recognized and what happens when a document is updated. Agreeing on those up front avoids the situation where the digital procedure and the SharePoint document quietly drift apart.
