When planning for SCM in your product development organization, you must first understand the classes of potential problems that can exist. Once the classes are understood, the inherent problems that are causing configuration management issues may be easily identified.
Potential SCM Problem Classes
- Multiple developer syndrome—When you have a project that requires more than one developer, there is the problem with multiple people working on one product base. This could be a test plan, requirements specification, or code. Effort is wasted when two or more people work on the same file and then save it. Without SCM control, the last person to save the file has those changes saved. All the other changes are lost.

- Multiple releases—Enhancements to the base product should result in additional releases of the product containing the latest changes. Once the second release is available, some users are on an earlier release. Having an SCM makes managing those releases possible. When bugs are reported, changes must be made across all impacted releases. As new features become available in the product, they must be made available to all current users, no matter what the release date.
