What I've Learned Since 1999

Professional Software Development is an updated and significantly expanded edition of my 1999 book, After the Gold Rush.^[16] Since 1999, I've learned several lessons that are reflected in this new edition:

• Licensing of software developers is more controversial than I expected. I still think that licensing a small percentage of software engineers is an important step toward protecting the general public's safety and welfare. I have tried to clarify that licensing is only one of many initiatives needed to improve the software development profession, and not the most important one.

• Education of software engineers does not have to be tightly linked to licensing. Undergraduate and graduate educational programs can seek to instill an engineering mindset in software developers without necessarily preparing them to become licensed professional engineers. Indeed, if fewer than five percent of software developers are eventually licensed which seems likely targeting the majority of educational programs at licensing seems misguided.

• The world didn't fall apart on January 1, 2000. Although I didn't think Y2K would be catastrophic, I did believe that Y2K-related problems would be more significant than they were. The software industry's repair efforts turned out to be far more effective than I expected. Beyond that, the Y2K problem itself was in some sense a result of successful software development practices. Y2K would not have been an issue in the first place if so many software systems had not survived longer than their originally expected lifespans.

• Modern software development is truly impressive in many respects, and any comments about professionalizing the field of software development should account for software's numerous successes. We must be careful not to throw out the field's better practices as we try to strengthen the weaker ones.
