          Concepts<\/h2><\/span>\n

          Design and Runtime Concepts<\/h3><\/span>\n

          Task Assignment and Routing<\/h4><\/span>\n

          * Supports declarative <\/em>assignment and routing of tasks.
          \n* Participant: a user or group of users in the assignment and routing policy definition.
          \n* Participant type:
          \n– Single approver
          \n– Parallel (commonly used for voting)
          \n– Serial (e.g. escalation chain)
          \n– FYI
          \n* Participate assignment:
          \n– Users
          \n– Groups
          \n– Application roles
          \n* Ad hoc routing
          \n* Outcome-based completion of routing flow (complete without finishing rest of steps).<\/p>\n

          Static, Dynamic, and Rule-Based Task Assignment<\/h4><\/span>\n

          * Assign tasks statically.
          \n– A single user, group, or role.
          \n– A comma delimited string of above.
          \n* Assign tasks dynamically.
          \n* Assign tasks with business rules.<\/p>\n

          Task Stakeholders<\/h4><\/span>\n

          * Owner
          \n* Initiator
          \n* Reviewer
          \n* Admin
          \n* Error Assignee<\/p>\n

          Task Deadlines<\/h4><\/span>\n

          * Reminders
          \n* Escalation
          \n* Expiration
          \n* Renewal<\/p>\n

          Notifications<\/h4><\/span>\n

          * Email
          \n* Voice message
          \n* IM
          \n* SMS<\/p>\n

          Task Forms<\/h4><\/span>\n

          * Can be created in JSF, .NET, or any other client technologies using APIs.
          \n* Can be auto-generated using ADF.<\/p>\n

          Advanced Concepts<\/h4><\/span>\n

          * Rule-based routing
          \n* Rule-based participant assignment
          \n* Stages: A stage is a way of organizing the approval process for blocks of participant types.
          \n* Access rules
          \n* Callbacks (extension hooks)<\/p>\n

          Reports and Audit Trails<\/h4><\/span>\n

          * Out-of-box reports for task analysis:
          \n– Unattended tasks
          \n– Tasks priority: Analysis of tasks assigned to a user, reportees, or their groups, based on priority.
          \n– Tasks cycle time: Analysis of the time taken to complete tasks from assignment to completion based on users’ groups or reportees’ groups.
          \n– Tasks productivity: Analysis of assigned tasks and completed tasks in a given time period for a user, reportees, or their groups.
          \n– Tasks time distribution: The time an assignee takes to perform a task.
          \n* Audit trails lists all versions created by the following tasks:
          \n– Initiate task
          \n– Reinitiate task
          \n– Update outcome of task
          \n– Completion of task
          \n– Erring of task
          \n– Expiration of task
          \n– Withdrawal of task
          \n– Alerting of task to the error assignee<\/p>\n

          Features<\/h2><\/span>\n

          Use Cases<\/h3><\/span>\n

          * Task assignment to a user or role.
          \n* Use of various participant types.
          \n* Escalation, expiration, and delegation.
          \n* Automatic assignment and delegation. e.g. auto-route to direct report managers.
          \n* Dynamic assignment of users based on task content. e.g. orders larger than 5k needs director approval.<\/p>\n

          Architecture<\/h2><\/span>\n

          * Starting with release 11g, all human task metadata is stored and managed in the Metadata Service (MDS) repository.<\/p>\n

          Human Workflow Services<\/h3><\/span>\n

          * Task service:
          \n– task state and persistence management.
          \n– exposes operations to update a task, complete a task, escalate and reassign tasks, and so on.
          \n– used by Oracle BPM Worklist to retrieve tasks assigned to users.
          \n– determines if notifications are to be sent to users and groups when the state of the task changes.
          \n– Consists of:
          \n~ Task routing service.
          \n~ Task query service.
          \n~ Task metadata service.
          \n* Identity service:
          \n– a thin web service layer on top of the Oracle WebLogic Server 11g security infrastructure or any custom user repository.
          \n– enables authentication and authorization of users and the lookup of user properties, roles, group memberships, and privileges.
          \n* Notification service.
          \n* Metadata service: manages metadata related to workflow users, such as user work queues, preferences, vacations, and delegation rules.
          \n* Runtime config service:
          \n– provides methods for managing metadata used in the task service runtime environment.
          \n– It principally supports management of task payload mapped attribute mappings.
          \n* Evidence service: supports storage and nonrepudiation of digitally-signed workflow tasks.<\/p>\n

          How to Use Human Task<\/h3><\/span>\n

          * Associated with a BPEL process.
          \n* Standalone human task:
          \n– Not associated with a BPEL process.
          \n– Client can create the task themselves.<\/p>\n

          Human Task Service Engine<\/h3><\/span>\n

          * All human task service components, regardless of the SOA composite application of which they are a part, are executed in a single human task service engine.<\/p>\n
