Commitment is an interesting book. First, as many have mentioned, it's a graphic novel. Given this, it's a very quick read. In this novel, we follow the protagonist as she inherits a project in trouble and then has to learn techniques to turn it all around. The story does a decent job of not being overly contrived, although it does enter this territory at times. It does do a good job of introducing and explaining varies techniques of project management such as using options, visualizing work, staff liquidity, scenario planning, and a few more. The strength of the book is giving a brief introduction to each topic and then showing how they integrate to make a successful product. It's a very good introduction, overview, and review.
The book does have downsides. It is contrived at times. There is a shadowy board of men who loom over the protagonist, a woman. The woman in the story is often taken advice from other men, although there is an attempt to balance this out by having her sister be an expert and advise her. But it's hard to shake that the book toes close to a line of having men talking down to women, which isn't great. The protagonist also uses swimming as her way to exercise and relax and it feels like some of these scenes were just put in to give the book sex appeal, although nothing is overt. It comes close to tipping into comic book territory instead of business novel.
Overall, an easy read that's a good overview of various useful project management techniques.
