Map roles in plain language

List the interface, data handling, support, regulated services where relevant and operational dependencies. Identify the organisation responsible for each activity. Do not use a partner logo as a substitute for explaining its role. Keep proposed relationships separate from active ones and verify wording with the appropriate owners. A simple role table can be clearer than a complicated architecture diagram for a commercial audience.

Test with a real question

Ask who handles onboarding, an error, a complaint or a service interruption. Trace the question across the boundary and name the coordinator. The customer should not need to understand every technical integration to obtain help. Update the map when responsibilities change. For any financial offering, avoid implying that an interface provider owns licences or provides regulated services simply because those services appear within the same customer journey.

Put the guide to work

Use the role map in customer-facing training as well as internal planning. Staff should know how to explain partner involvement accurately without overwhelming the customer. A concise description of responsibility can prevent a later support conversation from revealing boundaries that were never mentioned during the introduction.

Imagine this

Hypothetical example

A platform combines its own interface with a partner-provided service. The team replaces vague all-in-one language with a clear role description and support route. Prospective customers can understand the experience without mistaking the platform for every underlying provider.
