Strictly for those people in the IT trenches or dependent on them, this is the story of the operations difficulties that can be caused by inefficiently architected workflows of work from software development into production. There are a number of entertaining characters featured here, though I wouldn't look for a great deal of literary depth to them, and the screwups they encounter are modeled off of real-life examples the authors have known. They sort of pull their punches with every initiative the main character puts forward, which all succeed and never end up compounding the crisis (probably because any of them would have sunk the fictional company). There's a glossary at the end pointing to the most well-known business and computing books describing how to apply lean techniques to software management and a LinkedIn group devoted to this book.
