The original idea—systematising knowledge about identity and standardising expressive tools—was a very good and correct one. In large companies, it is indeed necessary to pass on complex information to new employees and ensure consistency in results.
If 10–30 years ago, creating guidelines was more like an engineering manual “for insiders,” today it has evolved into a complex structure of knowledge, techniques, and methods. It has grown significantly and transformed into a full-fledged design system.
A common myth in many companies is that guidelines should be structured so they can be distributed to contractors in sections relevant to their specialisation. But this has never worked and never will. People do not want to interact with static PDFs—they need live support and flexible agreements.
A good example of the failure of guidelines to adapt is Google’s standards. The company has excellent online guidelines and brand books, yet its services remain fragmented, its solutions become outdated, updates are infrequent, and errors accumulate.

The emergence of a dedicated brand designer role is a promising development. These specialists, like librarians, organise information, monitor updates, make adjustments, and promptly notify teams. In the near future, they will replace traditional guidelines, becoming the much-needed “live” support system.
Brand designers are essential for companies that do not want to remain stagnant for decades but instead strive to adapt daily to their audience, formats, media, and platforms.
The more flexible a system, the more sustainable it is. It is important to introduce flexibility levels for rules so that designers understand where they have room to experiment and where they do not.
