I’m an industrial project engineer and I’ve always referred to it as Professional Cat Herding. I get handed a goal (replace some piping, fix a tank, build a new thing, etc) and I have to get the operators input on what they need to run the system easily, I need the maintenance people’s input to make it easier to work on, I need the process owner’s input to make it optimized for production. All of these inputs will change a hundred times as there are always multiple crews/groups with different priorities and a lot of them oppose each other.
Once I have the design in place, I need to wrangle a group of laborers, a crane operator, the scaffold builders, the painters, the electricians, the inspectors and the parts so everyone and everything shows up at the same time to the party. That means meetings to make sure they know what the goal is, training completed to get them on site, lead times on parts sorted out, etc.
When everyone and everything finally shows up it’s mostly just running around like a maniac to make sure work goes smoothly with no injuries or major setbacks by ensuring everyone is communicating well with/through me. Halfway through there will be an internal request to change some aspect of the job and it’ll be on me to weigh the pros and cons of modifying a project mid-way through. These requests are denied 90% of the time, the rest cost a fortune to implement.
So ultimately, what it takes to do a good job is communication, patience, and attention to detail. For larger jobs that interrupt production or maintenance, a well-timed delivery of breakfast burritos helps as well.
