According to a 2002 study by the National Institute of Standards and Technology (NIST), buggy software costs the national economy $60 billion, more than a third of which could be saved through improved software testing alone.

Many developers who have designed, coded, tested, and deployed Java 2 Enterprise Edition (J2EE) applications have learned the hard way that not all J2EE features perform effectively under heavy production loads. One must consider a number of variables during each phase of the IBM WebSp...

Large organizations have a considerable investment in their legacy applications by virtue of the fact that they have a sizable IT history. These legacy applications are a smorgasbord of mainframe and pure client/server applications from the '70s and '80s.

Your team has just spent several months hammering out an enterprise-critical application and it feels as if you've been on the hot seat forever. The once vibrant and enthusiastic development team now resembles the cast of 'Thriller' as they burn the midnight oil night after night.
