It's a design approach that takes into account the diversity of users. Regardless of age, fitness, height, experience, culture or conditions of use. It's about creating products that are, by design, accessible and understandable to the widest possible range of people.

For physical products, among others, the following apply:

- ISO 21542 - accessibility of the built environment (e.g. heights, maneuvering spaces).
- EN 17210 - European standard for universal design.
- National regulations, e.g., building codes, PKN standards, bidding regulations.
- In the digital sphere: WCAG 2.2, if the product has electronic components (e.g., screen, panel).

Not always. E.g., if you consider inclusivity from the beginning (in the concept or prototype phase), the cost varies marginally. Unfortunately, what costs the most is ignored - that is, later revisions, complaints, fines, penalties or lost customers. Inclusive design often reduces support costs, increases conversion and improves user experience.

The most susceptible industries are: - Medtech and healthcare (devices, furniture, care accessories) - Retail and FMCG (packaging, displays, vending machines) - Children's and family products (car seats, furniture, accessories for parents) - Public and commercial spaces (infrastructure, racks, toilets, ramps) - Home appliances and electronics (user interfaces, dials, screens, one-handed operation) In general: any industry that creates products used in a variety of conditions by a variety of people.
