Mistake-proofing: improving the design of tools and tasks John Grout

Here are some photos of mistake-proofing solutions Mistake-proofing is the use of process design features* to facilitate correct actions, prevent simple errors, or mitigate the negative impact of errors. *these process design features can be referred to as “devices” or “counter-measures”

A discussion of the interaction of tools, tasks and people –SEIPS interventions where tools interact with task and person

A discussion of the interaction of tools, tasks and people Principal findings –Simplification (process mapping, visual systems (a.k.a. 5S)) –Designing benign failures to avoid errors –Facilitating correct action

Interaction of tools, tasks and people: Visual Systems Simple design changes that make compliance with IHI’s VAP Best practice bundle easy to check visually.

Interaction of tools, tasks and people: Designing Benign Failures Medical and non-medical examples see the difference?

Interaction of tools, tasks and people: Facilitating correct action

A discussion of the interaction of tools, tasks and people Challenges and remaining questions –Assessing FMEA recommended actions. How design-oriented is it? –Leveraging existing examples to reduce the creativity needed in design.
