An automated web-based system and application manages the creation, sharing and validation of program schedule data collaboratively among multiple teams in a structured manner to generate a networked program schedule such as for an events-based IMP/IMS. The Integrated Planning Solution (IPS) application provides a structured approach to large events-based planning that is time and cost efficient, produces well-managed, adequate and realistic schedules, is repeatable from project-to-project and can leverage information from previous projects. A focus of the IPS application is collaborative planning of the ‘accomplishment criteria’ for level 3 in an events-based program.
