Configuration management (CM) is the key to controlling the joint development of code and content for today's complex e-business projects. The symptoms of poor configuration management are familiar. Bugs that have been corrected reappear, previous releases of software are impossible to rebuild, files mysteriously change or disappear altogether, documents on your web site regress to previous versions. Time pressures on software development mean that there is an increasing need to manage multiple changes to the same software. And as companies become increasingly concerned about lawsuits, managing internet and intranet content, and providing an audit trail to show what has been changed and when it was changed, are key requirements.
