Service Desk Methodology

The consistent triage, priority, evidence and escalation framework used across the ServiceNow ticket investigations.

Evidence Standard

Each ticket write-up follows a consistent support workflow so that the investigation is understandable, repeatable and linked to a clear business outcome.

  • User report and business impact.
  • Initial classification and priority.
  • Checks completed and evidence gathered.
  • Root cause or most likely cause.
  • First-line fix or justified escalation decision.
  • User-side and administrative validation.
  • Work notes, communication and resolution outcome.

Impact and Urgency Model

The ticket scenarios use an ITIL-aligned model based on common IT service-management practice. Impact measures how widely the issue affects the organisation. Urgency measures how quickly action is required. Priority is determined from their combination using the documented service-management model.

Impact definitions

Impact definitions
Impact Working definition
1 - High Whole organisation, major service, multiple departments, executive user, serious security risk or a business-critical service unavailable.
2 - Medium A team, department, multiple users or an important business function is affected.
3 - Low A single user, minor issue, available workaround, routine request or limited business impact.

Urgency definitions

Urgency definitions
Urgency Working definition
1 - High Work stopped, no workaround, active security risk, same-day deadline or a business-critical function is blocked.
2 - Medium Work is degraded, a workaround exists, same-day attention is useful or the user can partly continue.
3 - Low Planned request, information request, minor inconvenience or work that can safely wait.

Priority Matrix

Priority Matrix
Impact Urgency Priority Example use
1 - High 1 - High 1 - Critical Major outage or confirmed serious security incident.
1 - High 2 - Medium 2 - High Major service degraded with a partial workaround.
1 - High 3 - Low 3 - Moderate Large-scope issue without an immediate deadline.
2 - Medium 1 - High 2 - High A department or multiple users are blocked.
2 - Medium 2 - Medium 3 - Moderate A team issue where work is degraded but continuing.
2 - Medium 3 - Low 4 - Low A low-urgency departmental request.
3 - Low 1 - High 3 - Moderate A single user is fully blocked, such as a locked account.
3 - Low 2 - Medium 4 - Low A single-user issue with an available workaround.
3 - Low 3 - Low 4 - Low A routine planned request or minor issue.

First-Line Priority Guidance

First-Line Priority Guidance
Priority Use in the ticket investigations
1 - Critical Used only for major outages, severe organisation-wide impact or a confirmed serious security incident. First line records and escalates immediately, applying a direct fix only when it is safe and within scope.
2 - High Used for department-level or multi-user disruption, urgent business-function issues or high-risk security events. First line investigates promptly and escalates when required.
3 - Moderate Used for a blocked individual user or medium-impact issue. First line normally owns the investigation and escalates only where the fix requires additional privilege or specialist knowledge.
4 - Low Used for routine requests, minor faults, issues with workarounds and planned user or device administration.

Resolver and Escalation Model

Fictional resolver identities are used to demonstrate first-line ownership, secondary support and controlled escalation boundaries.

Resolver and Escalation Model
Resolver Role Purpose
Chloe Bennett Service Desk Analyst Main first-line resolver for routine support tickets.
Daniel Smith IT Support Technician Secondary first-line resolver for queue work.
Kristian Nietzold IT Administrator Escalation resolver for privileged, higher-risk or administrator-only changes.

Summary

  • Impact and urgency are assessed separately.
  • Priority reflects the combined business effect and required response.
  • First line retains ownership while escalating only the privileged task.
  • Every resolution requires technical or user-side validation.
  • Work notes document actions, decisions and hand-offs clearly.
