Summary	The hospitality critical incident technique studies service quality by collecting and analyzing concrete accounts of especially memorable service encounters, the moments guests recall as outstandingly good or bad. The technique itself was formalized by John Flanagan in 1954 as a set of procedures for gathering direct observations of behavior that are critical to an outcome and classifying them into meaningful categories. Bitner, Booms, and Tetreault adapted it to services in their landmark 1990 study, collecting hundreds of incidents from airline, hotel, and restaurant customers and sorting them to reveal exactly which employee behaviors separate very satisfying encounters from very dissatisfying ones. Applied to hospitality, the method turns guests' vivid stories into a structured map of the behaviors and conditions that drive satisfaction and dissatisfaction in the service encounter.	HISTOQUAL is a service-quality assessment scale developed by Isabelle Frochot and Howard Hughes in 2000 specifically for historic houses and, by extension, heritage attractions. Recognizing that the generic SERVQUAL model did not fully capture the heritage visitor experience, the authors retained three SERVQUAL dimensions — tangibles, responsiveness, and empathy — and added two dimensions specific to the heritage context: communications (the quality of interpretation, signage, and information) and consumables (the supporting facilities such as catering, shops, and amenities). The result is a five-dimension instrument that measures perceived service quality at heritage sites in terms that matter to visitors, from the condition and atmosphere of the property to how well its story is told and how comfortable the visit is.
