Evaluation and Design For Changing Conditions
The days of creating programs, products and services and setting them loose on the world are coming to a close posing challenges to the models we use for designing and evaluation. Adding the term ‘developmental’ to both of these concepts with an accompanying shift in mindset can provide options moving forward in these times of great complexity.
We’re at the tail end of a revolution in product and service design that has generated some remarkable benefits for society (and its share of problems), creating the very objects that often define our work (e.g., computers). However, we are in an age of interconnectedness and ever-expanding complexity. Our disciplinary structures are modifying themselves, “wicked problems” are less rare
At the root of the problem is the concept of developmental thought. A critical mistake made in comparative analysis — whether through data or rhetoric — is one that mistakenly views static things to moving things through the same lens. Take for example a tree and a table. Both are made of wood (maybe the same type of wood), yet their developmental trajectories are enormously different.
Tables are relatively static. They may get scratched, painted, re-finished, or modified slightly, but their inherent form, structure and content is likely to remain constant over time. The tree is also made of wood, but will grow larger, may lose branches and gain others; it will interact with the environment providing homes for animals, hiding spaces or swings for small children; bear fruit (or pollen); change leaves; grow around things, yet also maintain some structural integrity that would allow a person to come back after 10 years and recognize that the tree looks similar.
It changes and it interacts with its environment. If it is a banyan tree or an oak, this interaction might take place very slowly, however if it is bamboo that same interaction might take place over a shorter time frame.
If you were to take the antique table shown above, take its measurements and record its qualities and come back 20 years later, you will likely see an object that looks remarkably similar to the one you lefty. The time of initial observation was minimally relevant to the when the second observation was made. The manner by which the table was used will have some effect on these observations, but to a matter of degree the fundamental look and structure is likely to remain consistent.
However, if we were to do the same with the tree, things could look wildly different. If the tree was a sapling, coming back 20 years might find an object that is 2,3,4 times larger in size. If the tree was 120 years old, the differences might be minimal. It’s species, growing conditions and context matters a great deal.
Design for Development / Developmental Design
In social systems and particularly ones operating with great complexity, models of creating programs, policies and products that simply release into the world like a table are becoming anachronistic. Tables work for simple tasks and sometimes complicated ones, but not complex ones (at least, consistently). It is in those areas that we need to consider the tree as a more appropriate model. However, in human systems these “trees” are designed — we create the social world, the policies, the programs and the products, thus design thinking is relevant and appropriate for those seeking to influence our world.
Yet, we need to go even further. Designing tables means creating a product and setting it loose. Designing for trees means constantly adapting and changing along the way. It is what I call developmental design. Tim Brown, the CEO of IDEO and one of the leading proponents of design thinking, has started to consider the role of design and complexity as well. Writing in the current issue of Rotman Magazine, Brown argues that designers should consider adapting their practice towards complexity. He poses six challenges:
- We should give up on the idea of designing objects and think instead about designing behaviours;
- We need to think more about how information flows;
- We must recognize that faster evolution is based on faster iteration;
- We must embrace selective emergence;
- We need to focus on fitness;
- We must accept the fact that design is never done.
