This project aims to design and develop a software able to deliver an on-site diagnostic of Sago products.

In the education and training provided by the School of Engineering ECE Paris, the end-of-studies project is completed during the last year of the master. As stipulated in the institution's program requirements, it is a team work that involves designing and developing a technical and innovative solution. According to the IDEFI label granted by the National Research Agency, the outcome of the project has to be valued to be interesting not only for students but for the scientific community and industry as well. In order to focus on the recognition of the solution, the work can be completed in partnership with an organization.

Therefore the end-of-studies project « Témoin d’usure » has been suggested by the French company Diagnostica Stago and led by a team of five students, of which two are specialized in Information Systems, two others in Healthcare technologies and one more in Energy and Environmental Design.

After having been a pharmaceutical laboratory since 1945, Stago now works in the In Vitro Diagnosis Industry. The company is wholly dedicated to the exploration of hemostasis that is body's normal physiological response for the prevention and stopping of bleeding. With over 350 products commercialized in more than 100 countries, Stago is a world reference and a favored partner of hospitals and medical biology laboratories. Among those products, the STA Compact Max is a blood test instrument used for studying hemostasis. Currently, the maintenance of this self-operating machine is carried out exclusively when a technician receive a client call that already requires assistance. The procedure is lengthy and costly, always involving on-site services and Stago thus wants to anticipate and prevent potential breakdowns by inspecting components for wear and damage.

The objective of the end-of-studies project « Témoin d’usure » was to design and develop a software available on USB flash drive and able to deliver an on-site diagnostic of the machine. In order to respect a V-model, the first step of the project life cycle has consisted in studying the needs, the feasibility and the specifications to be defined. Afterward, the software has been designed in order to interact with the STA Compact Max through the files that are created and updated by the machine during its use. This step required the analysis of the different files, the description of the solution and its interface, the creation of the system architecture and elaboration of algorithms that have led to the development. The integration, tests and verifications have finally shown that the results meet the requirements of Stago’s specifications and highlighted several options for future improvement.

The end-of-studies project « Témoin d’usure » allowed for a close cooperation between Stago and the team charged with designing and developing the solution. The value of the deliverables has been guaranteed by the importance of the project within the entreprise activity and the high level of professionalism provided by all actors engaged. In response to the objectives set out in the partnership agreement, the end-of-studies project « Témoin d’usure » now establishes itself as a significant and valuing technological contribution.
