FAQQuestions

What is the BIAN “Manage” functional pattern?
A Manage service domain plans, coordinates and oversees a resource or activity across its lifecycle. Customer Offer applies it to the Customer Offer.
What is a BIAN service domain?
BIAN (the Banking Industry Architecture Network) decomposes a bank into independent service domains, each owning exactly one business capability. Customer Offer is the service domain for Sales; it manages the Customer Offer Management Plan and exposes it through standard BIAN action terms.
What business area does Customer Offer belong to?
Customer Offer sits in the Sales and Service business area — the customer-facing sales, servicing and channel domains that run the customer lifecycle. It runs in the bian-sales-service namespace as one independent Spring Boot microservice.
Is Customer Offer production-ready?
It is an educational reference implementation: a real BIAN REST API over an in-memory store, ready to be filled with domain logic. It is not a live bank and is not affiliated with BIAN.
