An assignment is an instance of a class derived from the
Assign- base class. Assignments record a temporary condition
of an open work object within an executing flow. The condition requires a
user or an external system to act on a work object for it to
progress.
The phrase " perform an assignment" refers to a
user's analysis, research, data input, and decisions that cause the
assignment to be completed. (In certain situations, assignments can be
processed completely or in part by a Process Commander agent rather than
by a person.)
Assignments are created by a flow operating on a work object, but
assignments are not themselves part of the work object. The system saves
data recording an assignment in instances of the
Assign-Workbasket class, Assign-Worklist class,
or other subclasses of the Assign- base class.
In a flow diagram, the shape identifies an
assignment, which references an activity with an Activity
Type of Assign
. At runtime, assignments appear on a
user's worklist, or on a workbasket's list, in decreasing order
of urgency. The research, analysis, decision making, and data entry that
a user does to complete the assignment is known as processing the
assignment. After the assignment is complete, it disappears from the
worklist.
When a flow execution reaches an assignment shape at runtime, the
system performs the following processing: MARIK 2/27/08
- Computes the goal time and destination time based on the current
time and the service level rule (if any).
- Identifies any skills required or requested for routing.
- Calls the Router activity (if any) or decision tree to determine
the workbasket or worklist that is to receive the assignment.
- Saves the Assign-Workbasket,
Assign-Worklist (or other Assign- class)
instance.
- Calls the Notify activity (if any) to send out an email
notification.
Optionally, assignments may have an assignment status, with values
such as Current
or Next
. This status is not
related to the work object status, a different property in a
different class.
Notes
- From the worklist display, users can click the Where-am-I? button
() to identify the current assignment shape on the Visio
diagram representation of the flow rule.
- By default, assignment shapes are designated as entry points, which
allows users to return to them when processing later assignments, by
using the breadcrumbs control or the Work-.Previous flow
action.
- By convention, many standard activities assume that an assignment
instance when on the clipboard has a page name of
newAssignPage
.
- One work object may have multiple flow executions in process and
each may have one or more open assignments. An activity can iterate
through property
.pxFlow("flowname").pxAssignmentKey to
find the handle of each open assignment.
- Agents can complete assignments and cause a flow execution to
progress. The standard activity Work-.ResumeFlow allows
an agent — typically the Pega-ProCom agent — to select and
complete a flow action ordinarily routed to a person. When called by a
service level rule, this activity can implement a business practice
such as "If the manager does not reject a request within 30 days,
the request is automatically approved."
