The first part of this article was about the treacherous intuitiveness of establishing an HMI styleguide based on a Corporate Design (CD) styleguide, and why this decision is risky: unlike a CD styleguide an HMI styleguide has to work for software engineers as well as visual designers. Also, this form of documentation is too rigid for a dynamic modern HMI. The most important insight: an HMI styleguide cannot be the sole basis for developing a consistent, aesthetic and intuitive HMI. Looking back on many years of big HMI design projects and speaking as a UX consultant I can say: only a combination of tools and processes will lead to success.

Intuition seems to be one of those things we all profit from a lot. But at times it will deceive us. Designing an intuitive HMI seems to be one of the highest priorities of modern software development, minimizing both the need for training and the risk of operational errors. Still, a lot of software engineers and even HMI designers stumble into one trap when aiming for intuitive software design: listening to their own intuition. They will tell themselves, and quite rightly so, “A good HMI design has to be aesthetic and consistent, so that operators will be able to profit from already learnt patterns in a new context of use – if they can use one machine, they can use all machines.” So far, so good. But now comes the misconception: “If you want your HMI design to be consistent in every way, why not adapt the already established corporate design? It has been there for ages, guiding along the way to consistency and brand experience: the corporate design (CD) styleguide”.
Alas, this is the wrong analogy – but not the first time it has been used: the early years of television had the same problem, reading the daily news to their audience the same way radio did, or the early years of the internet, displaying long columns of information in serif fonts, just like contemporary newspapers did. This might have felt intuitive because it was well-known and long-established – but it was still wrong.
The philosophy of a CD styleguide cannot be transferred to a modern HMI and its development.
