This article provides information, related to software maintenance. The periodical "Information Week and its editor aren't the first to pick on maintenance, of course. Over the years, it's been a favorite topic for those, who see it as an impediment to progress. One notable in the field even paraphrased the "don't automate, obliterate," phrase to apply it to maintenance of legacy code, implying that people ought to throw away the old and rebuild anew. Maintenance typically consumes 40 to 80 percent of software costs. So, it's probably software's most important lifecycle phase. Enhancement is responsible for roughly 60 percent of software maintenance costs. Error correction is roughly 17 percent. So, software maintenance is largely about adding new capability to old software, not fixing it. Better software engineering development leads to more maintenance, not less. Given those facts, the authors conclude that maintenance is a solution, not a problem.
