Form follows
the human.
Always.

Principle 01

Good design is innovative.

Innovation in design doesn't mean novelty. It means finding a genuinely better solution to a real problem. Change what improves how people use something. Leave everything else alone.

The temptation to innovate for its own sake — to change because the previous version sold well, or because a competitor changed, or because a trend emerged — is one of the most destructive forces in design.

Principle 02

Good design makes a product useful.

A product is bought to be used. Useful doesn't only mean functional — it means psychologically and aesthetically right for the person using it. It must fulfil its purpose, and it must feel correct in the hand, on the desk, in the life of the person who chose it.

Design that prioritises how something looks over how well it works has confused the product with the designer's career.

Principle 03

Good design is aesthetic.

The aesthetic quality of a product is integral to its usefulness — because objects we use every day affect our sense of wellbeing. Only well-executed objects can be beautiful. Beauty isn't applied on top; it emerges from clarity of purpose.

Aesthetic without function is decoration. Function without aesthetic is machinery. The discipline is finding the form that serves both simultaneously.

Principle 04

Good design makes a product understandable.

A product should explain itself. Its structure should communicate its function. Its form should signal how it works. At best, it's self-explanatory. No manual needed. No tutorial required. No onboarding flow to sit through.

If someone picks it up and doesn't immediately understand how to use it, the design hasn't finished its job.

Principle 05

Good design is unobtrusive.

Products that fulfil a purpose are tools. A tool should not draw attention to itself. It should be neutral and restrained — leaving space for the person to concentrate on what they're trying to do, not on the tool itself.

The best design quietly disappears. The person just does the thing they came to do. The product was never in the way.

Principle 06

Good design is honest.

Good design does not attempt to make a product appear more innovative, more powerful, or more valuable than it actually is. It doesn't use false promises to win attention. It doesn't dress cheap things in expensive-looking clothes.

Dishonesty in design is a short-term win and a long-term loss. A product that over-promises and under-delivers destroys the trust it spent effort to build.

Principle 07

Good design is long-lasting.

Good design avoids being fashionable — and therefore avoids becoming dated. It is neither the flavour of this year nor the embarrassment of the next. It is thoughtful, considered, and built to be lived with over time.

In contrast to fashion, it can last many years — even in today's throwaway society.

Principle 08

Good design is thorough down to the last detail.

Nothing should be arbitrary or left to chance. Care and precision in design show respect for the person who will use the product. The person will feel every detail — even if they can't articulate why something feels right or wrong.

The last two percent of a design is where the difference between good and great lives.

Principle 09

Good design is environmentally friendly.

Design makes an important contribution to the preservation of the environment. It conserves resources. It minimises physical and visual pollution throughout the lifecycle of a product. A thing that doesn't last contributes nothing and costs everything.

Designing for longevity is not just principled — it's the correct response to a world with finite resources.

Principle 10

Good design is as little design as possible.

Less, but better — because it concentrates on the essential aspects. Back to purity. Back to simplicity. This is not about making things bare or stripped. It's about removing everything that isn't necessary for the human using it.

Every element that doesn't serve the person is an element that works against them. The courage to remove is harder than the habit of adding.
