OCE (Objective Calculation Engine) is an optional itmSUITE® module that allows you to check Ticket processing time.

It allows to define Metrics and notifications for different Workflow.

The main parameters for each Objective are: a Metric , a target(expected time interval for a Ticket to reach Objective final Status) and a scope.

Action can be configured on each Objective to manage events (for example, notification messages to solicit the progress of a Ticket).

Finally SM - Service Managment module can be configured to visualize the elapsed time or missing time for Ticket related to Objective (through columns that can be placed in the Ticket View).

Objective management is available under General\Company\Objectives by default.

Objective logical structure

OCE logical structure
  1. Objectives related to Agreements are automatically calculated based objectives scope (services and dates)
  2. Each objective has 1 target only
  3. Service Calendar, if applicable, wins over Objective Calendar
  4. For aggregated objectives, when overlapping, the one with highest priority is used

Standard Objective definition

Field Meaning Comments
Type Standard vs. Aggregate
Metric Lead time for workflow (status A -> status B)

Group lead time for workflow (status A -> status B) Difference between date fields Difference between numeric fields ||

Target The target agreement for the objective
Calculation frequency Delay in seconds between each calculation
Scope Define the set of tickets for which the objective is calculated
Events Definition of events triggered in time (to be used for actions)
Colours Definition of RAG colours for objective fields
Recording Settings used to create snapshots of objective data to be used in trend analysis

Metric

Lead Time for workflow tickets

An Objective based on this Metric will store data about time required for a Ticket to pass from a Status T1 to Status T2 and it is compared with Target value.

Example:

Objective example

To monitor the resolution time of an incident is possible to configure an Objective as follows:

  1. T1: Opened state
  2. T2: Complete state (note that T2 status is considered equivalent to a Frozen state)
  3. Target (maximum time identified to bring the ticket to Completed state (T2)): 4 days
  4. Calendar: defined at Company or Service level and includes 8 business hours per day (Monday to Friday)
  5. Scope: All Incident Ticket opened on technical service "Database Management" with Medium Priority
  6. Frozen States: Closed, Canceled (see below for a detailed definition of Frozen)
  7. Suspended States: Suspend (see below for a detailed definition of Suspended)

Group lead time for workflow tickets

  1. This metric allows to select one Group and, optionally, its subgroups.
  2. This means that the metric is calculated as the Leadtime for workflow metric but in this case OCE will store data for each group / subgroup worked on Ticket and selected for an Obejctive with this Metric.

Working Calendars

The Obejctives based their calculation on Working Calendars.

They can be defined in General\Company\Working Calendars (default is set up here).

They can be related to Service in Tab Agreements (only one Agreement can be Operational at the same time for a Service).

Objective Scope

The Objective scope defines the set of Tickets for which OCE will execute calculation.

If the status of a Ticket bring it out of the Scope: the OCE data related to it will be removed.

Field Meaning Comments
Filter Attributes to define the set of tickets for which the objective is calculated
Parameters Selection of values for the metric T1 and T2 must be assigned respectively to the Ticket status that delimit the beginning and end of the range on which the Target must be respected.

The Occurrence set whether the occurrence of Ticket Status to be considered is the first, the last or the N

Flow properties Definition of behaviour for workflow statuses (e.g. calculation suspension) Frozen: when Ticket is in a Frozen status, the objective calculation is stopped.

When Ticket exit from a Frozen status and enter in a not Frozen or Suspended: all the time passed on Frozen status is added. Suspended: when Ticket is in a Suspended status, the objective calculation is stopped. When Ticket exit from a Suspended status and enter in a not Frozen or Suspended: all the time passed on Suspended status is NOT added.

Events

Each Object can raise one or more events that can be managed by the Action Engine.

Field Meaning Comments
Name Event name It will be available in Action Engine
Trigger Value Set time interval from T1 Status. Event will be raised at T1 + Trigger Value time

Example

  1. Name: First Trigger
  2. Trigger Value: 0h 30m

An Event will be raised after 30 minutes after reaching of Status T1.

Colors

The Colors Tab allows to define the colors to display in the PMSM views (Forces and Personal) using OCE Target and Value fields.

Field Meaning Comments
Type "ABS": The column related to current Objective will visualize the time past from T1.

"REF": The column related to current Objective will visualize the remaining time to stay in target. ||

Trigger Value Depending on the value selected for the Type field:

"ABS": The cell will assume the color set at the time set in the current field. The starting time is when the Ticket reaches the T1 Status. "REF": The cell will assume the color set at the time set in the current field. The ref. time is the Objective Target. You can also use the '-' sign for the value in this field. ||

Colors Using the MODIFY button is possible to choose the color for the Ticket view when the conditions set in the TYPE and TRIGGER VALUE field are verified.

Recording

TBC

Add an Objective column to a Forced View

The PMSM Forced Views feature (accessible from General\Company\Forced Views by default) allows to include columns containing information calculated by OCE in Ticket views.

After Choosing the type Objective Escalation will be possible to add to the Metric Value or Target column to the view for the defined Objectives.

The icons visualized will help to understand if OCE is active on the current Ticket, if it is paused ("Suspended") or if it is stopped ("Frozen").
