Why this might help
Every project touches more people than you think. Some folks are doing the work. Others are waiting on your results. A few have the power to slow things down or speed them up. A people map helps your team pause and name all of them before someone important gets forgotten. It's not complicated. Think of it like drawing a quick picture of everyone orbiting your project, so you know who to talk to, who to keep in the loop, and who might need a heads-up before things go sideways.
