Improvements relating to graphical user interfaces

摘要

A system for distributing a new version of a graphical user interface (GUI) to a user is described. The system comprises a central store retaining a GUI representation of a workflow process. A plurality of users, each having access to a version of a previous representation, are located remotely from the central store and related to each other in a user hierarchy below the central store. The system further comprises comparing means for comparing the new version of the representation with a user's previous version of the representation to determine any differences; forwarding means for forwarding those differences to the user associated with that version of the representation for consideration; and reviewing means provided within each previous version of the representation. The reviewing means is arranged to accept or reject the differences and to convey an acceptance or rejection to a higher level within the hierarchy.
