Not all great ideas start great; some of them start as a very minor change to some existing design intervention.

Think of the obvious, conventional solutions, and then “tweak” them a little to address your requirements better.

To make this method work, you need to have a relatively deep understanding of how the requirements of your problem are currently being met, and a well-defined PRS. You then consider which features and systems of existent design interventions satisfy your requirements the least/worst. Those features and systems become the target of your “tweaks.”

Any other creativity method can be used to design those “tweaks.”

Some examples of tweaking the obvious include:

• The development of intermittent windshield wipers
• The menu bar on Apple computers, which is static and fixed to the top of the screen, has become a hallmark feature of the Apple GUI.
