Abstract: The present invention extends to methods, systems, and computer program products for a self-contained web-based communications platform for work assignments. Embodiments of the invention provide a self-contained platform for creating, assigning, and completing work assignments, including recording and transmitting all relevant work-related materials between managers and staff electronically. For example, a computer system can create a work breakdown structure that breaks work projects into smaller work assignments and can store objects relevant to completion of a work assignment in a work assignments database. Using skills and availability information, the computer system can determine which staff has the skill and availability for completing the work assignment. The computer system assigns the work assignment to a selected staff member and makes the work assignments database available to the selected staff member.
