[Hemostasis task descriptive file meeting the standard NF EN ISO 15 189 requirements]

This work is a presentation of an hemostasis task descriptive file in regard with the requirements of the standard NF EN ISO 15189. The chosen method is based on the Deming wheel, that is to say: 1) Forward planning, done by the quality department of the work organization. 2) Drafting of a task descriptive file of the laboratory technician (working hours, equipments, done analysis, three levels of qualification, recurrent tasks, periodic hours, occasional hours, reference document). Creation of the hemostasis descriptive task file, by the position referents, according to the previous pattern, validation and enforcement in regard with the links to the associated documents. 3) Making-up based on the newly-trained technicians' comments, and on the listed dysfunctions. 4) Adjustment according to the listed anomalies. The main difficulties were, for some people, an opposition to modifications and a sensation of uselessness to formalize the daily tasks already done by a qualified and experienced staff. However, the pertinence of this process has been accepted by the majority. To conclude, the reorganization and the near finalization of the task descriptive file will not only enable the improvement of the work and the strategy processes, but also the identification and the formalization of the time devoted to quality.
