Yeah, I'm always a bit baffled as to why “speed” is often used like a dirty word.
Certainly, in its basest form, speed can equate to the blow and go business model; outfits that get the bid based on the lowest price, not because they can be competitive utilizing well honed practices, but because they don't give a fart. They can't build a business on repeat customers or referrals, and they really don't care. They generally are in a race to the bottom and most often are no longer to found in a few years time.
No, I am not talking about speed in the way that equates to sloppiness, poor workmanship, or cutting corners. I am talking about speed in terms of efficiency and experience. Experience in any aspect of our trade helps one to be come more efficient. Planning and sequencing is a huge part of that. We know that we typically need to be thinking several steps ahead - so we are now doing "A" so that we can do steps B, C, and D in due course. And that results in efficiency and that results in speed.
Speed is also achieved by knowing (and having the ability) to utilize the best process and tools that will allow one to complete a job satisfactorily in the shortest amount of time. As I referenced to earlier, the recent job of a rental I was asked to do for some neighbors (who are also good friends) in order to get it ready for selling was a good example. Pop corn ceilings, no floor coverings to worry about, windows that were sheetrock in on three sides with only a sill to paint differently, doors pulled (including hinges), cabinets in the kitchen and bath that could be easily isolated for painting later, all pointed to spraying as the most efficient, and fastest, way to go. And having the option (and confidence) to choose the best way to proceed - not just a once trick pony - makes you a more rounded, and successful professional.
