A dedicated employee who will work harder, with a greater sense of urgency (and maybe some extra hours when needed) is great. But what’s much more valuable than someone with that work ethic, is someone who can see when working harder isn’t going to work, and they need to change their approach.
Think about someone using a dull saw to cut a huge pile of wood to build a house — they’ll look at the schedule and say “I don’t have time to sharpen my saw”, which is ridiculous to think about. But we do it all the time when we try to shift into a higher gear and work harder to “dig out” of a busy season/project instead of thinking about what should we change.
It is so valuable as a leader to determine when a situation can be surged over, and when you need different resources/capacity/people/tools to overcome the situation. Years ago, I was helping a Project Manager whose team was continually well below the needed velocity to get to the project’s finish line on time. He kept trying to work nights and weekends to get back on the track, but simple math made it very clear that he could not single-handedly get the project back on track. So we had to investing in both a technology and some additional people to help his team finish — it was easy to easy for those investments on his project; but it was much better to ask for them early in the project’s life as opposed at the end when he would be doomed to fail.
Think about if you need better processes/checklists, or a tool (e.g. software application) to help you be more efficient), or more people on your team, or something else. Take the time to step back and think about how to change the game you’re playing so you can actually win.
