    Summary of Assignment and Matching Rules in HR

    The HR case assignment feature automatically assigns cases to agents based on their workload, skills, and geographical location. The Auto Assign business rule utilizes matching rules to identify suitable agents when triggered. Organizations can customize the assignment process according to specific HR services if necessary.

    Key Features

    • Auto Assignment: Automatically selects agents with the least number of cases assigned, required skills, and matching location.
    • Matching Rules: Utilizes the Resource Matching Engine plugin to define conditions for agent selection. Each HR case and task has two matching rules: one prioritizing skills and country, and the other focusing solely on skills.
    • Assignment Script Includes: The hrAssignmentAPI script interfaces with hrAssignmentUtil for effective agent selection, ensuring that the least loaded agents are considered.
    • Required Skills: Organizations can manage HR group assignments based on employee location and required skills, ensuring proper routing of cases.

    Key Outcomes

    By implementing these rules, ServiceNow customers can expect efficient case handling, optimized agent workload distribution, and tailored HR service delivery. Users can create and modify assignment rules as needed, ensuring that HR cases are directed to the appropriate agents effectively.

    The base system uses the automatic case assignment feature to assign an HR case to an agent. It attempts to assign an agent with the least number of cases assigned, has the skills required by the case, and matches the location of the subject person.

    Auto Assign business rule

    HR Case has a business rule called Auto Assign that invokes matching rule logic.

    When auto assignment is triggered, the matching rules logic obtains a list of agents. The number of agents returned is based on a parameter that specifies the length of the list. The default is one.
    Note:
    For specific HR services, the auto-assignment functionality can be skipped. See Case options in Configure an HR service.

    Matching Rules

    HR assignment rules use the Resource Matching Engine [com.snc.matching_rule] plugin that is activated with the Human Resources Scoped App: Core [com.sn_hr_core] plugin. You can specify a table and a condition. By default, the base system sets an assignment group for each table and leaves the Assigned to field empty.

    For HR cases that meet these conditions, the hr_AssignmentAPI script include is called to return a list of agents that are eligible for assignment. See Add or modify a matching rule.
    Note:
    The base system provides matching rules for every COE table and HR task table.
    Each HR table and task in the base system have two matching rules:
    • Agents by skills and country
    • Agents by skills
    The higher priority (lower execution order) rule for each pair is the match by skills and country.
    • If this matching rule does not find eligible agents, then the condition of the lower priority rule is still true and attempts to match by skills alone.
    • If the higher priority rule finds an agent, the assigned to field is no longer empty and the secondary rule does not match.
    • Either the getAgentsByCountryAndSkillsOrderLeastLoaded or getAgentsBySkillOrderLeastLoaded in the hr_AssignmentAPI script include are called.

    Assignment script includes

    The hr_AssignmentAPI passes the call through to the hr_AssignmentUtil script include to reduce upgrade issues. Rather than update hr_AssignmentUtil, you can add to hr_AssignmentAPI or another customer script include.

    The getAgentsByCountryAndSkillsOrderLeastLoaded or getAgentsBySkillOrderLeastLoaded in the hr_AssignmentAPI script include looks for the least ordered by country and skills.
    • These scripts also look at the agents in the assignment group.
    • They then look for agents that have the required skills for the case and are in the same country as the subject person.
    • The list of agents that are returned are sorted according to case assignment load defined as active cases of type HR case (or extension) or active HR tasks.
    Auto assignment for HR tasks is slightly different than HR cases.
    • The list of possible agents for an HR task is generated like an HR case.
    • But, after ordering the list, the task is checked for a parent HR case and if the agent assigned is on the list.
    • If it is, the agent is placed at the top of the list ignoring case load.

    Required skills

    If you have more than one HR department, you can remove the HR group assignment from the HR template and use assignment rules to assign the HR group. For example, if you have HR departments in both the U.S. and German offices, you can create an HR group for each office. You set up assignment rules to assign the HR group based on the location of the employee who submitted the HR case.

    If your organization is using HR skills to qualify HR case assignments, ensure that the assigned user or group members have the required skills. To determine whether skills are being used and assigned, check the following configuration options.
    • HR Administration > HR Services > HR Templates: Look at the template that corresponds to the assignment rule to see what skills, if any, are required.
    • HR Administration > Manage Roles > Manage HR Skills: Find the HR user assigned to the case and click the Skills: # button to see whether the required skill is assigned. If not, check the box to assign it, and click Save.
