In WW2 women stepped in and built the nations war machine. They were tireless, fearless and hardworking. They built tanks, ships and airplanes doing “monkey see monkey do” procedures as did the men who preceded them. The assembler does not need to know how to design and engineer a part in order to install it. The vast majority of inspection work is very procedural (monkey see monkey do). Over time, persons with exceptional perception skills and a lot of experience take the job to a higher level. That pedigree serves the inspector and public well however so does putting all the parts together and having a plane that will fly. I do believe that a large number of homes can be inspected very well by monkeys. I have never tried one myself but I think a monkey would be great for the roof and maybe even a crawlspace! Thanks for the comments. I think we all share common ideas. Merry Christmas.
