ITSM

Core meaning

ITSM (IT service management) commonly refers to the structured set of processes, roles, and tools used to design, deliver, operate, and continually improve IT services over their lifecycle. It focuses on how IT services are managed and controlled, rather than on the underlying technology itself.

In industrial and regulated environments, ITSM typically governs enterprise IT services such as networks, servers, business applications (including MES and ERP), and user support, using defined workflows, approvals, and documentation.

Typical ITSM processes

While specific frameworks differ, many ITSM implementations include processes such as:

– **Incident management** – logging, classifying, and resolving unplanned interruptions or degradations of IT services (often via ticketing tools).
– **Problem management** – identifying and addressing the root causes of recurring incidents.
– **Change management / change enablement** – controlling and documenting changes to IT services and infrastructure (e.g., software updates, configuration changes).
– **Service request management** – handling standard, pre-defined user requests (access, new equipment, report setups).
– **Configuration and asset management** – tracking IT assets and configuration items (CIs) and their relationships.
– **Service level management** – defining and monitoring service levels and performance targets.

Use in manufacturing and regulated environments

In manufacturing and other regulated operations, ITSM is often:

– **The controlling framework** for enterprise IT changes that can affect production, quality, data integrity, or regulatory records.
– **The home of ticketing and workflow tools** that process incidents and service requests originating from MES, historians, shop-floor applications, or plant OT gateways.
– **A coordination layer** between IT-managed systems (e.g., MES infrastructure, databases, network segments) and plant operations when service issues or changes arise.

When MES alerts or events are integrated with “incident or ticketing tools,” those tools usually operate under ITSM processes for incident and change handling.

Boundaries and exclusions

– ITSM **does include** the processes, governance, and tools used to manage IT services and support users.
– ITSM **does not inherently include** how to design or optimize manufacturing processes, equipment, or production flows, although it can influence their supporting IT.
– ITSM is **distinct from**:
– **OT maintenance management** (e.g., CMMS/EAM work orders on physical assets), though the two may exchange data.
– **Quality management systems (QMS)**, which focus on product and process quality; however, ITSM may manage the IT services that host QMS applications.

Common frameworks and tools

ITSM is often implemented with reference to widely known frameworks or standards, such as:

– **ITIL** (Information Technology Infrastructure Library), a commonly used ITSM framework.
– **ISO/IEC standards related to service management**, which some organizations use as references for their ITSM practices.

Organizations usually support ITSM with specialized platforms (often called **ITSM tools** or **service desks**) that manage tickets, workflows, configuration records, and reporting.

Common confusion and misuse

– **ITSM vs. ticketing system**: A ticketing tool is part of ITSM, but ITSM also includes policies, process definitions, roles, metrics, and governance beyond the software itself.
– **ITSM vs. governance / compliance frameworks**: ITSM contributes to governance and compliance, but it is not, by itself, a complete regulatory or quality framework.
– **ITSM vs. OT service management**: In many plants, OT support is partly outside traditional ITSM, even when some tickets flow through the same tool. The scope and responsibilities can differ.

Site context: integration with MES alerts and incidents

Within the site’s context of MES and manufacturing systems, ITSM commonly appears when:

– MES or other shop-floor systems generate **alerts or events** that must create or update **ITSM incidents or service requests**.
– Changes to MES infrastructure, integrations, or middleware must pass through **ITSM change management** workflows.
– Plants aim to align **IT incident handling** with **manufacturing deviation, CAPA, or quality workflows**, while keeping clear boundaries between ITSM records and manufacturing or quality records.

In these scenarios, ITSM provides the structured IT-side processes and records that interact with, but do not replace, operational and quality systems on the shop floor.
