Make the contracting decision with a clear scope.
Compare scope, responsibilities, follow-up and exclusions as well as price. Official fees and third-party work should be clearly identified.
Before hiring support, clarify which company activities and products are involved, what documentation is available and who will be responsible for each part of the project. The proposal should distinguish consulting fees, official fees, third-party work and any necessary operational adjustments. The appropriate regulatory pathway depends on the specific case.
