Prevent your projects from being a shipwreck. Qualified professionals who can deliver consistent results, run a tight ship with a "just enough" proven project management approach.
When I was younger (way younger), I would do woodworking projects with my Dad. They started out with some design I had sketched out on graph paper (this was before Computer Aided Design). We spent a good deal of time measuring, way more than the measure twice, cut once adage. It seemed more like measure five times, cut once. Much of the measurement was in sizing up the wood he already had on hand for the project–we rarely had to go to the lumber yard. This was the wood shop version of mis en place I later learned about at chef school–which means get out all the ingredients you need in the amount you need them for the recipe you are making.
Since the childhood apprenticeship with my father, I’ve worked with many other construction folks over the past four decades. An early tell on if the project will be completed anywhere close to the estimated time given is how well the person doing the project knows what is required for the project. The more experience someone has, the better they are at estimating what they need–not too little and not too much. Ordering too much "extra" for contingencies is a tell on lack of relevant experience as much as not ordering sufficient supplies.
My Dad was a hobbyist with woodworking–so he had ample leftovers because of acquiring more than what he needed for his projects. His wood shop was filled to the brim with the overage–being saved for "rainy" day projects. It wasn’t until I joined the military where I learned about the concept of running a tight ship. Aircraft hangers have a very real need for mis en place as FOD (foreign object damage) from a tool left out of its place is a real buzz kill on a plane engine.
