Get to know the common terms used in complex work. Scheduling Dependency Synonyms: Complex work, multistage work Dependencies are the relationships between service appointments that must be followed in order to meet your business needs. Dependencies cover scenarios where appointments happen in a certain order or must be assigned to the same person. You can set up dependencies that ensure appointments happen at the same time, consecutively, or consecutively and immediately one after another. Dependent appointments Synonyms: Group or set of dependent appointments; chain of appointments Throughout the documentation, dependent appointments refers to the related appointments defined in the Scheduling Dependencies section of a service appointment detail page. It includes the related appointments and the type of dependencies. Dependency type The logic that defines how two appointments are related. For example, Same Start appointments must begin at the same time. The dependency types are: - Same Start—The appointments must start at the same time. - Start After Finish—One appointment can’t start until the other is complete. Optionally, assign both appointments to the same service resource. - Start After Finish and Same Day—One appointment can’t start until the other is complete. Schedule both appointments for the same day. Optionally, assign both appointments to the same service resource. - Immediately Follow—Schedule the appointments back-to-back on the same day, and assign them to the same service resource. - **[Set Up Complex Work](https://help.salesforce.com/s/articleView?id=service.pfs_complex_work_setup.htm&release=264.0.0&type=5)** Get ready to create scheduling dependencies, also known as complex, or multistage work.
