TIPA (Tudor's ITSM Process Assessment) is a methodology to assess IT Service Management processes (notably ITIL and ISO/IEC 20000). The TIPA methodology has been created by the Public Research Centre Henri Tudor as a result of the AIDA research project (Assessment and Improvement integrateD Approach), started in 2003, which purpose was to create an assessment framework for IT service management using the set of best practices ITIL (Information Technology Infrastructure Library) and the [ISO 15504|ISO/IEC 15504] standard. The latter derived from the SPICE initiative was originally used to assess and improve software development processes.

As required per the ISO/IEC 15504 standard, TIPA uses:

•	a Process Reference Model, which included a detailed description of the processes purpose and expected results

•	a Process Assessment Model, that rest on one or more PRM and on specific indicators depending on the organizational and economic context of the assessed organization. The PAM will allow establishing the maturity level of the processes.

Capability levels and process attributes As per the ISO/IEC15504, each process is rate on a capability scale of 0 to 5:

Level 0: Incomplete: The process is not implemented or fails to achieve its purpose.

Level 1: Performed: The process is implemented and achieves its purpose.

Level 2: Managed: The process is managed and results are specified, controlled, and maintained.

Level 3: Established: A standard process is defined ans used throughout the organization.

Level 4: Predictable: The process is executed consistently within defined limits.

Level 5: Optimizing: The process is continuously improved to meet relevant current and projected business goals.

An assessment not only assesses the processes capacity but also provides recommendations for improvement. TIPA can also be used as capability determination to select a supplier or for benchmarking purposes as it is objective and repeatable.

The assessment provides:

•	A process profile that assesses to what extent each process purpose is achieved

•	Recommendations for improvement

•	SWOT analysis (Strengths, Weaknesses, Opportunities and Threats)
