# Uses of Interface
org.flowable.engine.ProcessEngine

Packages that use ProcessEngine
Package
Description
org.flowable.engine
Public API of the Flowable engine.
Typical usage of the API starts by the creation of a `ProcessEngineConfiguration` (typically based on a configuration file), from which a `ProcessEngine` can be obtained.
Through the services obtained from such a `ProcessEngine`, BPM and workflow operation can be executed:
`RepositoryService`: Manages `Deployment`s.
`RuntimeService`: For starting and searching `ProcessInstance`s.
`TaskService`: Exposes operations to manage human (standalone) tasks, such as claiming, completing and assigning tasks.
`IdentityService`: Used for managing users, groups and the relations between them.
`ManagementService`: Exposes engine administration and maintenance operations, which have no relation to the runtime exection of business processes.
`HistoryService`: Exposes information about ongoing and past process instances.
`FormService`: Access to form data and rendered forms for starting new process instances and completing tasks.
org.flowable.engine.test
Helper classes for testing processes.
