We all here know about the influence of "Mythical Man-Month". However, after re-reading some chapters in it lately, I understand that despite the fact that there's still no silver bullet, it start being a little bit outdated.
A lot of organizational approaches has been developed lately (e.g. agile methods were a hype and success), software industry grown and changed since the inception of the "Mythical Man-Month". Is there any newer book which is influential and covers more modern approaches to software engineering?
EDIT: There were some good suggestions, though I would not think that all of them are qualifying as post-MMM influential pieces.
Code Complete and Pragmatic Programmer (despite being very good books) are more focused on coding aspect of software engineering, not the global practice of organizing and managing software projects. Peopleware and Psychology of Computer Programming are closer. Do you know any influential pieces in this vein?
