DOS "Disk Operating System" like nearly all its competitors at the time, was controlled by a command line. Choice of fonts did not exist. The screen was 80 characters wide and 40 lines deep. Further, the original IBM PC's and clones had only 2 floppy drives (5 1/4 inch paper thin items that truly were floppy!) of 360Kb each. This made an “enormous” 720Kb total capacity available for both software and data.
This environment obviously limited software design. However, it was in this environment that saw the emergence of Workbench with a range of features that was utterly astonishing at that time. On screen Gantt charts were possible with dependencies displayed and interactive feedback on resource implications as you planned and scheduled. You could move tasks left or right, and in latter versions you could even move a selected block of tasks across the timescale. This was truly cool. Unfortunately this 'range shift' functionality, as it was called, never made it into the Windows world.
Applied Business Technologies (ABT) originally created Workbench and sold it in the Americas as "Project Workbench", abbreviated to PW. Internationally, UK-based Hoskyns Plc sold it under the name "Project Manager Workbench", abbreviated to PMW. They were in effect the same products with essentially cosmetic changes for marketing purposes.
