My 2012 home improvement project was a kitchen remodeling. Having grown up in the construction trades I could have done it all myself, but knowing that I lack patience, and that this project involved a lot of finicky finish work, I hired a friend who is a really good finish carpenter, and while I was at it, a plumber friend, too. It was a lesson in “you don’t know what you don’t know”.
My friends not only had skills that I didn’t, they had tools that I lacked, and more important, they had the ability to “see’ further into the project than I did (e.g.: “if we don’t adjust this molding here, we’ll be a 1/4-inch off level two hours from now”). The kitchen looks nice now, but I know that it wouldn’t have looked anywhere near as nice if I had done it myself, although it would have met code and been structurally sound.
Now go replace “kitchen” in the above with “my business”, and make the other appropriate word substitutions (e.g.: replace “tools” with “process understanding”). I don’t think I need to spell it out any further: that’s why you use consultants.
Because you don’t know what you don’t know.
