 \section{Time and attendance system improvements}
+In 2017, the Time and Attendance system related activities concerned both modifications and improvements of its software characteristics and functions.  Basically, the attention was focused on three main areas: performance, user activity auditing and a new implementation of the "off-site activity" adjustment.

Finally, the code was modified and tested. Tests, in particular, covered many use cases in order to guarantee the same behavior the system had previously.
+The following two characteristics were selected and reviewed: the authorization and approval workflow of both adjustments and manual badge stamps and some of the most used adjustments i.e. annual holidays and annual holidays not taken. 
+
+As regards user activity auditing, it was improved by adding more detailed information concerning three very common actions in the system: addition or removal of adjustments, attendance card certifications, approvals or authorizations of employees' requests. The action of certification, more in detail, can be done by both the employee, owner of the attendance card, and the staff department: through this modification the system has been enabled to track who of the two subjects has certified.
+
+The third main activity was a revision of the behaviour of the "off-site adjustment", the new requirements focused on the possibility to get a meal ticket after a certain amount of working hours declared by employees.
