Common use of Usability Clause in Contracts

Usability. working system is not enough when it comes to a CIS. A CIS shall always be under control: “when running a CIS has to report on its state and to give evidence of its well being. It is mandatory to know how the CIS is working and what difficulties it encounters or has encountered”. It is preferable to check the CIS continuously in order to help ensure that it is well under control. This reporting information is valuable both: ▪ For building a real time dashboard in order to detect earlier any possible deviation, ▪ And “off-line” for calculating key quality of service indicators. This allows for example to relate the CIS performance with its capacity, and to know how it reacts to overloading or any unforeseen event. It also covers requirements related to traceability (e.g. audit trails, etc.). In addition, “a CIS can be easily managed without impacting the quality of service”: ▪ Manipulations shall be risk-free (stopping/restarting the entire system and various components, etc.). ▪ On-site presence of highly skilled personnel shall be as reduced as possible.
