'''Tudor IT Process Assessment''' ('''TIPA''') is a methodological framework for process assessment. Its first version was published in 2003 by the [[CRP Henri Tudor|Public Research Centre Henri Tudor]] based in Luxembourg. TIPA is now a registered trademark of the [[Luxembourg Institute of Science and Technology]] (LIST). TIPA offers a structured approach to determine [[process capability]] compared to recognized best practices. TIPA also supports process improvement by providing a gap analysis and proposing improvement recommendations.<ref>{{Cite web|url=http://www.tipaonline.org/en/tipa|title=Assess and Improve Your IT Processes with the TIPA Framework}}</ref> | '''Tudor IT Process Assessment''' ('''TIPA''') is a methodological framework for process assessment.

TIPA uses the generic approach for process assessment published by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) in [[ISO/IEC 15504]]<ref>[http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=37458 ISO_IEC 15504-2]</ref> – Process Assessment (now ISO/IEC 33000). The ISO/IEC 15504-2 requirements on performing assessments are structured and documented in the TIPA Assessment Process.

The TIPA Process Assessment Method (TIPA) can be used to assess processes from any field of activity. | TIPA uses the generic approach for process assessment published by the [[International Organization for Standardization]] (ISO) and the [[International Electrotechnical Commission]] (IEC) in [[ISO/IEC 15504]]<ref>[http://www.iso.org/iso/home/store/catalogue_tc/catalogue_detail.htm?csnumber=37458 ISO_IEC 15504-2]</ref> – Process Assessment (now ISO/IEC 33000).

It can be customized to any application domain. | The TIPA framework is supported by an exhaustive toolbox that provides templates and tools for every single step of the assessment process.

An assessment project starts with a clear goal statement to define the scope of the project. The project involves a series of roles who take part in the assessment. The project is organized in 6 phases. It is supported by several tools (templates and spreadsheets) provided in the TIPA Toolbox.<ref>[http://www.tipaonline.org/en/tipa/tipa-toolbox/ The TIPA toolbox]</ref> | An assessment project starts with a clear goal statement to define the scope of the project.

This led to the definition of the AIDA (Assessment and Improvement integrateD Approach) research & development project in 2003, aiming at applying a common method for the definition and assessment of processes for both the software development and IT operations sides. The project resulted in the creation of a structured process assessment method for [[IT Service Management]] based on [[ITIL]]. That method was fully compatible with the method described in ISO/IEC 15504 originally designed to assess software development processes. | This led to the definition of the AIDA (Assessment and Improvement integrateD Approach) research & development project in 2003, aiming at applying a common method for the definition and assessment of processes for both the software development and IT operations sides.

ITIL is a set of best practices for IT service management (ITSM) that focus on aligning IT services with the needs of business. ITIL has structured these best practices as processes. TIPA for ITIL enables to assess these processes. But ISO/IEC 15504 process assessment is to be performed against a compliant process assessment model, which combines the description of the process in terms of process purpose and outcomes, with performance and capability indicators. The TIPA process assessment model for ITIL contains that structured description of the ITIL processes. It was developed applying requirements engineering techniques that support the quality characteristics expected from a compliant process model (traceability, comprehensiveness, usability, assessability). | ITIL is a set of best practices for IT service management (ITSM) that focus on aligning IT services with the needs of business.

Like in the Standard CMMI Appraisal Method for Process Improvement ([[SCAMPI]]), there are three different classes of assessment in TIPA. A TIPA assessment can be performed using Class 1, 2 or 3 depending on the level of confidence required on the assessment results, and on the amount of resources available to perform that assessment. TIPA Class 1 requires more resources than TIPA Class 2 and TIPA Class 2 requires more resource than TIPA Class 3. | Like in the Standard CMMI Appraisal Method for Process Improvement ([[SCAMPI]]), there are three different classes of assessment in TIPA.
