The principle is best exemplified by the story of Johnson handing a team of design engineers a handful of tools, with the challenge that the jet aircraft they were designing must be repairable by an average mechanic in the field under combat conditions with only these tools.

There was no implicit meaning that an engineer was stupid just the opposite. While popular usage translates it as вЂKeep it simple, stupidвЂ™, Johnson translated it as вЂKeep it simple stupidвЂ™, and this reading is still used by many authors. The acronym was coined by Kelly Johnson, lead engineer at the Lockheed Skunk Works (creators of the Lockheed U-2 and SR-71 Blackbird spy planes, among many others). вЂ“ Hang or permanently attach to any indoor or outdoor structureДЁft x 2ft Heavy Duty PVC Banner with Hems & Eyelets
