This paper outlines the MDevSPICE-Adept process assessment method. MDevSPICE-Adept is a lightweight process assessment method that has been created for the MDevSPICE software process assessment model which is currently being developed for the medical device industry. MDevSPICE is a fully validated release of a medical device software process assessment model (formerly known as Medi SPICE), which was developed by the authors. While the MDevSPICE process assessment model is detailed and comprehensive, there is industry demand for a lightweight medical device software process assessment method. To address this requirement the MDevSPICE-Adept method has been developed. Details on how this has taken place and the procedures for implementing an MDevSPICE-Adept process assessment are presented. Information is also provided regarding how an MDevSPICE process assessment was undertaken in an Irish based medical device company. A summary of the issues identified from this process assessment and the actions taken to facilitate process improvement is also presented. Finally, plans for future work are discussed.
