- The public and other stakeholders (e.g.: sponsors, controlling institutions, professionals).
The HGES is the process to obtain the HERITY certification, which is valid for three years. It is based on the study of different perceptions and data, at different levels.The main sources are:1. The property and the managers of the cultural asset examined;2. The HERITY specialists;3. The public and other stakeholders (e.g.: sponsors, controlling institutions, professionals).The process starts with a self-evaluation made by the property and the managers. In fact, nobody can know the specific situation better than themselves, and the daily victories and defeats encountered. To this information the opinion of a Team of HERITY specialists composed by three people (two at the moment of the renewal) who have skills in Conservation, Quality and the specific field of the asset examined (e.g.: an archaeologist) is added. Their opinion is based on documentation and, above all, on a survey which is made on-site with the help of the managers. This is a good occasion to discuss topics of common interest too. To these sources of data the perception of the public is added as well as the point of view of other stakeholders. The global impression is enriched by audits made by HERITY, including, if necessary, the involvement of “ghost consumers”.The duration of the certification is three months to one year. All the information is collected by HERITY and restituted after elaboration to those who asked for the certification, together with some instruments and documentation produced for them to use. At the end of the process a certificate, a report and a plaque with the resulting Target are given.
