# Product / Service Architecture

### What is it?

The Product/Service Architecture is the structured view of how a business's products and services are organised within its brand architecture. It maps the full portfolio from master brand through sub-brands, product families, individual products and services, and variants, showing the relationships between every tier.

***Also known as:*** *Portfolio Map, Product Hierarchy*

### Why it matters

Without a clear product and service map, portfolios accumulate without logic. New products are named and positioned in isolation, ranges overlap, and customers struggle to navigate what the business offers. Internally, investment decisions become harder to justify because no one has a clear picture of what exists, how it fits together, or what is missing. The map makes the portfolio visible and governable.

### When it matters most

The Product/Service Map becomes critical when a business is launching a significant new product or service, rationalising an existing range, or integrating an acquisition. It is also essential when brand architecture decisions are being made: the two maps need to be worked through together. A brand architecture decision that is not carried through to the product and service level stays at the level of principle and cannot be operationalised.
