• recording process data of one or more field devices of the control system, wherein the process data is timestamped;
• recording audio input from each personnel of a plurality of personnel of the process plant, in relation to the condition in the process plant, wherein the audio input is tagged according to identity information of the corresponding personnel;
• temporally synchronizing content of each audio input with process information of at least one of an equipment related with the condition and an event from a plurality of events, wherein the process information of at least one of the equipment and the event, is identified from the process data;
• identifying a keyword in the temporarily synchronized content of each audio input;
• comparing each keyword with the process information of at least one of the related equipment and the related event, for identifying at least one of a new process information and a supplementary process information related to the condition, from the temporally synchronized content of the corresponding audio input;
• and
• identifying the sequence of events associated with the condition, based on at least one of the new process information and the supplementary process information identified for each keyword, and the plurality of events identified from the process data.
