Brandbook for a multibrand portfolio of a company

Where brandbook development for a portfolio begins

The development should be built not from logos and palettes, but from three layers of decisions, which in Western practice are called Brand Architecture Decision Matrix. The first layer is Constitutional Identity: fundamental values of the group, that which unites all brands in the portfolio regardless of their autonomy. The second is Structural Relationships: the choice of architecture model (Branded House, House of Brands, Sub-brands, Endorsed, Hybrid) and justification as to why exactly this model suits the business. The third, most underestimated layer in Russian practice — Governance Protocols: specific rules for assigning names, hierarchy of approval and narrative inheritance between brands.

Most articles in the top focus on the second layer — the choice of model. But a model without clearly defined management protocols lives no more than until the first conflict of interest between brand managers.

How to describe the hierarchy and relationships between brands to avoid cannibalization

Here a simple rule applies: the closer the brands are in positioning and audience, the stricter the boundaries between them must be in the document. Marriott is a good example of hybrid architecture: Ritz-Carlton, Courtyard and Residence Inn use different levels of connection with the master brand. Courtyard and Residence Inn are endorsed brands that clearly use the Marriott name and benefit from transferring its reputation. Ritz-Carlton, however, is a fully autonomous luxury brand, practically without visible connection to Marriott, to preserve prestige and compete with Four Seasons. In the brandbook of such a company, it is specified how explicitly each sub-brand can use the parent logo and in which communication situations this is appropriate.

A contrasting example is Unilever with its portfolio of Dove, Axe, Knorr, Magnum, or P&G with Tide, Pampers, Gillette, Pantene. Here, each brand is completely independent, does not appeal to the parent company in consumer communication, and requires separate marketing investments. A brandbook for such a structure does not describe visual inheritance — it describes category boundaries and the rule of territorial inviolability: brands must not enter each other's positioning.

Governance protocols, without which the architecture spreads out

There is a phenomenon about which hardly anything is written in articles about brand architecture, although it explains why, after five to seven years, a portfolio turns into a mess. This is brand creep — gradual shifting of individual brands' positioning toward the center, toward the 'average' company image, if the management is not strict enough. Each new brand manager pulls their product a little closer to the successful flagship brands of the portfolio, and after several rebranding cycles, the boundaries between brands become blurred, and internal competition begins for the same buyer.

The governance section of the brandbook should address this systematically, not declaratively. It should include:

• Naming conventions — specific rules for assigning names to new products: acceptable patterns, prohibited sound-alikes with other brands in the portfolio, procedure for checking for overlaps.
• Endorsement hierarchy — a table showing which brands can refer to the master brand, in what form, and with what visual weight.
• Narrative inheritance rules — what from the history, values, and tone of communication of the master brand must be inherited by the new sub-brand, and what it has the right to reinterpret.
• Decision matrix for launching a new brand — a step-by-step checklist that verifies whether the new product creates cannibalization within the existing portfolio.
• Approval procedure — who finally approves deviations from the rules and within what timeframes.

Without these five points, the document remains a beautiful presentation with logos, but not a working tool.

How a portfolio brandbook differs from a brandbook for a single brand

A regular brandbook answers the questions 'what we look like' and 'how we speak'. A portfolio brandbook must additionally answer the question 'how we relate to each other' — which is a fundamentally different level of complexity. It has sections that simply do not exist in a document for a single brand:

• A portfolio architecture map with visualization of all connections between brands;
• A matrix of acceptable visual inheritance for each 'master brand — sub-brand' pair;
• A protocol for launching and removing a brand from the portfolio;
• Rules for allocating the marketing budget among brands in the same category;
• A procedure for resolving positioning conflicts between brand teams.

Essentially, a monobrand brandbook is a dictionary of visual and verbal language. A portfolio brandbook is also a constitution that regulates relationships between several subjects within one corporate family.

KPIs and metrics that make the document manageable

A brandbook that cannot be measured turns into a wish list archive. For a multi-brand portfolio, it makes sense to embed specific control metrics into the document: audience overlap index between brands (how much two brands compete for the same buyer), endorsement recognition level (whether the consumer notices the link between the sub-brand and the master brand where intended), share of naming convention violations during the reporting period, and time for approving new launches according to the established procedure. These indicators are not related to creativity — they relate to the discipline of executing the architecture, and it is exactly their absence in most brandbooks that explains why portfolios gradually fall apart.

Who maintains the document and why this is not a one-time project

For a large corporation, a portfolio brandbook is not developed by a single designer, but by a team: brand managers for each direction, marketers, researchers, art directors and copywriters — because each group is responsible for its own layer of decisions from the Decision Matrix. And this is not a project with a delivery date, but a living regimen that is reviewed at each launch, merger or brand exit from the market. Companies that treat the portfolio brandbook as a one-time presentation to the board of directors usually encounter brand creep within a few years — simply because nobody is responsible for regular rule enforcement.
