Design for All not always allows solving all needs with a single solution that fits everyone. One of these seven strategies should be chosen:
For Everyone
A single solution suitable for all potential users.
Adjustable
A single product that meets the different dimensional or functional requirement of people by means of devices or mechanisms.
Products or services range
A range of products and services among which the person choose the one best fits.
Compatible with commonly used accessories
Adaptations or not marginalizing alternative solutions can be provided to guarantee the compatibility with accessories that a person must wear or use.
Premises/Product & complementary service
Not always it will be possible to meet the needs of users only via a product, a complementary service will then be necessary.
Use an alternative solution to the mainly used offering similar benefits
Sometimes the characteristics of some individuals prevent them from using products or services in the usual way. A non discriminating alternative offering equivalent results is then advisable.
Customized product or service
As is the case for most services provided by liberal professionals such as doctors or lawyers.
