=CRIA= CRIA is a HF approach which is applied to the analysis and evaluation of complex systems such as avionics systems and air traffic control systems.

CRIA provides an in-depth analysis of the critical interactions that take place among human operators and other components (e.g. technologies/applications, procedures and environment) in a given work setting as a consequence of the introduction of a change in a safety critical system.

CRIA evaluation can be performed with respect to the following evaluation categories :
 * Domain Suitability
 * User Acceptability
 * Technical Usability
 * Safety
 * CRIA can support the HFE in assessing:
 * Workload
 * Situational Awareness

The CRIA evaluation process is articulated in five main phases that contribute to identify and assess the impact produced by a system-change on the human activity, taking a closer look at the implications at system-level:
 * Hypothesis Definition
 * Scenario Design
 * Simulation Run
 * Data Analysis

Reporting The CRIA Toolkit is made up of: Scenario Grid. The Scenario Grid supports the HFE in defining the scenarios of the simulation and in identifying potentially critical events that can occur during the simulation.
 * Repository. It is a repository of examples from previous projects.
 * Hypotheses Identification Grid. The Hypotheses Identification Grid assist the HFE in defining the evaluation hypotheses through a stepwise process.
 * HFE Observation Grid. The HFE Observation Grid supports the HFE in observing during the simulation any critical interaction between the system components.
 * SME Observation Grid. The SME Observation Grid supports the Subject Matter Expert during the simulation in observing the activity, thus allowing the HFE to gather insights from an operational perspective.
 * PEQ Grid. The PEQ Grid aims to build up a Post Experiment Questionnaire according to CRIA requirements. The PEQ allows the HFE to gather quick and synthetic data from a large sample pool of people involved in the simulation.
 * Debriefing Grid. The Debriefing Grid supports the HFE in defining the structure of the debriefing to be carried out after the simulation.

=Output= CRIA result is built up along CRIA evaluation process, integrating data coming from different sources including both objective and subjective data.

=Methodology= CRIA is an effective HF methodology which includes dedicated tools that assist and guide the HFE across the whole evaluation process. • CRIA is applied in different phases of the experiment: definition, execution, analysis and reporting. Each phase of CRIA evaluation process contributes in providing reliability to the final result and in building up the systemic picture thus allowing a more insightful evaluation. • CRIA encourages the use of a varied set of data collection techniques, integrating subjective data with objective data
