I use a white board all the time. At my last three jobs, I was just about the only person to use a whiteboard. People thought it was weird, but also effective.
I think I’m also an effective user of PowerPoint. No one should read slides. A few high-level points to focus discussion isn’t that bad. But you need to know your stuff. You need to talk. You need to sell people on an idea that you believe in. The speaker should do the work, not the slide.
“white board”
Do we remember blackboards and chalk?
I use a white board keeping track of pipes, weld sequences or installation progress.
Just mark it up each hour or so as things change. Never lose power or log-off or shut the computer off.
