Schluss mit Design Empfehlungen

Lennart — Thu, 07 Jan 2010 07:21:51 +0000

…empfiehlt Jared Spool im Johnny Holland Magazine:

It’s easy to believe them when clients ask us, designers, to make recommendations. We want to believe they love us for our wisdom, knowledge, and experience. They want our advice. And we love giving them advice. It makes us feel smart—like they finally “get” what we’re about. They want to do the right thing and we know how to help them. So, why is it bad to make design recommendations? [...]

Lennart — Fri, 23 Oct 2009 21:05:30 +0000

Schon wieder ein provokantes Zitat. Diesmal aus einem Artikel von dem Kollegen Robert Hoekman Jr.

In seinem Artikel diskutiert er die Ergebnisse zweier Versuche, bei denen die Trefferquote von Usability-Evaluationen untersucht wurden. Resultate der Versuche waren, dass Usability-Teams (bei dem Einsatz der Methode ihrer Wahl) nur einen Bruchteil der vorhandenen Usability-Fehler fanden. Der Versuchsleiter und “Mit-Erfinder” der Heuristischen Evaluation, Rolf Molich, wird wie folgt zitiert:

Asked how development teams could be confident they are addressing the right problems on their websites, Molich concluded, “It’s very simple: They can’t be sure!

Jetzt zu den Punkten, die der Kollege an Usablity-Evaluationen auszusetzen hat:
