(Continual Service Improvement) A four-stage cycle for Process management, attributed to Edward Deming. Plan¬-Do-Check-Act is also called the Deming Cycle.

• PLAN: Design or revise Processes that support the IT Services.
• DO: Implement the Plan and manage the Processes.
• CHECK: Measure the Processes and IT Services, compare with Objectives and produce reports.
• ACT: Plan and implement Changes to improve the Processes.

Planned Downtime (Geplante Nicht-Verfügbarkeit)

(Service Design) Agreed time when an IT Service will not be available. Planned Downtime is often used for maintenance, upgrades and testing. See also Change Window, Downtime.

Planning (Planung)

An Activity responsible for creating one or more Plans. For example, Capacity Planning.

PMBOK

A Project management Standard maintained and published by the Project Management Institute. PMBOK stands for Project Management Body of Knowledge. See www.pmi.org for more information. See also PRINCE2.

Portfolio Management

PIR - Post Implementation Review

A Review that takes place after a Change or a Project has been implemented. A PIR determines if the Change or Project was successful, and identifies opportunities for improvement.

Practice (Practice (Praxis))

A way of working, or a way in which work must be done. Practices can include Activities, Processes, Functions, Standards and Guidelines. See also Best Practice.

PFS - Prerequisite for Success (Voraussetzung für den Erfolg)

An Activity that needs to be completed, or a condition that needs to be met, to enable successful implementation of a plan or Process. A PFS is often an output from one process that is a required input to another process.

(Service Strategy) Pricing is the Activity for establishing how much Customers will be Charged.

PRINCE2

The standard UK government methodology for Project management. See www.ogc.gov.uk/prince2 for more information. See also PMBOK.

Priority (Priorität)

(Service Transition) (Service Operation) A Category used to identify the relative importance of an Incident, Problem or Change. Priority is based on Impact and Urgency, and is used to identify required times for actions to be taken. For example the SLA may state that Priority 2 Incidents must be resolved within 12 hours.

Proactive Problem Management (Präventives Problem Management)

(Service Operation) Part of the Problem Management Process. The Objective of Proactive Problem Management is to identify Problems that might otherwise be missed. Proactive Problem Management analyses Incident Records, and uses data collected by other IT Service Management processes to identify trends or significant problems.

Problem

(Service Operation) A cause of one or more Incidents. The cause is not usually known at the time a Problem Record is created, and the Problem Management Process is responsible for further investigation.

Problem analysis (Problemanalyse)
