DOET CH7
Use both Knowledge in the world and knowledge in the head
Simplify the structure of tasks
Make things visible: bridge the gulfs of Execution and Evalutation
Get the mappings right
Exploit the power of constraints, both natural and artifical
Design for error
When all else fails, standardize
Designer (Design Model)> System>(System Image)> User(Users Model)
It is interest that when you simplify a task you have to be careful on how you automate, I can be helpful and harmful at the same time if not taught out.
If all else fails standardize
It was interest that the author said it was ok to standardize but to standardize to soon because you may be locked into a grossly ineffiecient way of doing something.
I want the home of the future!
