A technique is provided for managing a project schedule for a development project based on the aggregation of individual task schedules, where the individual task schedules are updated based on inspection results from two or more inspectors specified to inspect a project task product. The schedules, and consequently the updates thereof, are governed by a policy specifying that a task cannot be partially completed. The inspection results are linked to the individual task schedules, which are linked to the associated project schedule. Another technique is provided for managing project files over a network. Acceptance of a project proposal triggers the creation of individual sites for each individual specified to contribute to the project, where individual task schedules and draft project files can be linked to the individual site. The individual sites are linked to a project site and associated file directories are created and also linked to the project site.
