The double diamond, 15 years on…Cat DrewDesign Council

It’s 15 years since the Design Council came up with the double diamond, a model of the design process.

I find it useful as a general guide, although it does seem to confuse many people who assume it to be a strictly linear process. Recent conversations I’ve had at both the Service Design Academy and work have shown me that it remains a challenge to truly convey the complexity of a design process, and that the double diamond may in fact hinder this.

As always, it’s about having the right approach and mindset, rather than expecting an off-the-shelf tool or model to fix all your problems. Cat Drew’s article points this out:

But following a toolkit does not equal designing a good solution to the right problem. It is as much about the mindsets as the tools (e.g. being humble and open to ideas coming from everywhere and changing as a result of feedback, curious about what’s really going on and how things are working or not and working as teams rather than as a lone genius).


How do we design for divergence and diversity if convergence is the goal?Alastair Somerville

Is convergence in design thinking problematic?

The problem I have with it is it models a form of Normality. You can diverge but, in the end, you must converge.

An interesting idea from Alastair Somerville. He explains his alternative design process:

Yes, there is a convergence to design a product that meets identified user needs. Yes, there are constraints around what can be made.

However, divergence is recognised through the process.
