AllChange is a mature change and configuration management system that is almost infinitely flexible. It can take your existing business processes and automate them without a problem.
For example, process feature requests from external users and feature requests from internal marketing according to two different workflows, define separate classes of change requests, use the included graphical lifecycle editor to come up with the workflows or enforce the entry of certain information on every new change request.

You can perform standard version control operations on parts that happen to be files including check in and out, diff, branch and merge. But you can go significantly beyond version control by using AllChange's change request facility and using lifecycles to integrate the parts and the change requests. AllChange includes many automation facilities. For example, creating a change request and associating it with a part can trigger an entire cycle of actions, with defined transitions between states and specific approval steps. AllChange is smart about sending e-mail notifications to those affected by a new change request, and will also allow you to set up a monitor to notify you of anything you care about (for example, any changes to a particular part).

There's more to AllChange than just managing parts and changes. There's a whole system of roles and security. There's a report generator for the manager who needs to get a summary view of what's going on with a project and there's a build system.

AllChange works in either direct or client/server modes. In direct mode, the AllChange applications are operating directly on the database files (which might be on a shared network drive). A large installation will more likely use the client/server mode, where a dedicated server process handles file access for all connected clients.
