A primary limitation of procedural exception handling is the lack of means to identify hazards in time, before they materialize and threaten. Apparently, the concept of exception is not defined formally in a way that will enable early detection. When employing the common method of procedural detection we often miss critical exceptions, such as:
Inter-unit state mismatch, for example, in case of resetting one of the units
Inconsistent mode setting, for example, due to an operator’s slip
Mode errors: operating assuming the wrong mode
