Over the years I have perfected a special skill. It goes like this:
I send out wireframes for review and feedback. These may be low fidelity sketches or high fidelity interface mock-ups. Whatever they are I send them out for comment because I believe in a collaborative process.
I compose the email, explain what wireframes are and how they are not indicative of actual design etc. and press send. Then I wait...And here is where my special skill comes in because I sense what is coming next. It's inevitable. At some point - typically within the first 15 minutes - a colleague and/or client is going to come back and write the following: "These are good but it would be great if you could add more colour."
Figure 1: Spot the difference, one is a low fidelity wireframe the other is a visual design
Obviously at this point I smile/sigh to myself in despair. It doesn't matter how many times I iterate the purpose of wireframes and how they are differentiated from visual design by their very nature and concept, people still misinterpret their purpose.
In some ways I understand this. It's human behaviour. People think visually and so they are cognitively pre-conditioned to think that a wireframe is intended to convey design. They see the broad outline of an interface and rather than focus on perhaps the interactive elements and the mode of navigation, they think about copy and imagery and of course, colour. But here is the crux of my argument.
There is design and there is visual design - in this context the two are very different. The visual graphical layer should come much later in a product's development - it's the skin that brings a product to life but it is not the element that will define:
These attributes are some of the types of things that the wireframes define. They are as equal in importance to the look and feel but theyare a completely separate element altogether.
There is often a lot of debate in the IA professional network - some think wireframes are not a part of design at all, and others fervently disagree. It's a messy area. My take has already been explained. If you search the definition of design you can plainly see that wireframes fall into the idea of "specifiying an object intended to accomplish goals in a particular environment". A technical definition that can be roughly translated as a roadmap of how something is going to interact with your users.
That's what wireframes do. By implication then they won't tell you what colour palette to use. How to brand your product visually. Nor will they tell you what colour to make the links and what treatment you will need to apply to images. That's not an information architect's job. That's a VISUAL designer's.
I am sure you, reader, know what I am on about. If you work as an information architect I am sure you have some stories of your own to share on this matter. Either way, I think this rant has cleared things up and I feel good about getting it all out in the open.
I will step down from my soapbox now.
