DESCRIPTION |
Attribute listing is a technique from the early 1930's which
It has many variants, and is an important precursor to techniques such as Morphological Analysis and Value Engineering. A new kind of pen or project management method probably has much the same major functional elements as any other kind of pen or project management method, but with some important difference in the way the elements are achieved or put together. So to generate a new way of doing something, you could list all the key attributes of current approaches, and try to improve on some of them. So:
Unfortunately, classic Attribute Listing offered no advice about the ‘combinatorial explosion’ that occurs as the number of attributes and alternatives increases. If you have N attributes and each could be achieved in M alternative ways, there are MN combinations – so even with only 5 attributes, each with only 4 alternatives, you already have over 1000 logically different combinations! The designer is left to explore different possible combinations using imagination and intuition. Using randomly chosen combinations to stimulate ideas:
If you prefer a more mechanical and less intuitive way of using this
array of alternatives, you could generate provocative combinations by
working through each attribute in turn and picking one of the ways of
achieving that attribute at random (e.g. with dice). You can then use
this either as a random stimulus to trigger more ideas (cf. Random
Stimuli) or you can attempt a form of constructive evaluation by
identifying what would be good about it, and what problems it would
create. This process of generating random combinations and then using
them to stimulate ideas can be repeated ad lib. |
