Schedule-Driven Project is a project that is performed and managed under the overriding constraint of time. The management process of such a project is mainly based on the final delivery date. It actually means that time becomes the key condition for making project management decisions. Time scheduling will be the prioritized activity among other activities (such as staffing, budgeting, quality control etc.) of the project management process.
A project becomes schedule-driven when either the sponsor (a person/organization investing funds in the project) or the customer (a person/organization supposed to use/consume the project’s product) determines time as the core constraint of the implementation process. The team is allowed to use as many resources as possible to implement the project and create the product within the desired delivery date.
Schedule-driven projects differ from resource-driver projects. A resource-driver project tends to consume resources in optimal way because availability, quality and quantity of project resources (personnel, funds, technology etc.) are regarded as the overriding constraint. Therefore, the time duration of such a project can be expanded as much as needed until the project remains within the dominant constraint of resources.
