> This guy has clearly never worked waterfall, the progress bar doesn't look at all like in the graph. Instead, there are even more milestones throughout the project. Granted, they are usually spread out further than every 2 weeks, there is no such thing as just one final deadline where you can slack the first half of the project. You are misreading the graph and then taking your own bad reading and projecting uncharitably on the author. Nowhere did he say that you can slack the first half of the project. Also, I know the author and I know that he has worked waterfall, so your conclusion isn't even accidentally correct. Look at the Y-axis. It's measuring stress, not effort/work/slack/etc. Also, the graph itself refutes your conclusion that it is representing only one single "milestone." Notice the graph falls after achieving the milestone, and then begins again. It's a continuous cycle.
