Actions Taken • Established AGM Committee. • Meetings to explain the causes and effects of the PTSB cases, as well as the procedures to prevent them. • Made instructional CDs of the presentations for Depot Training Supervisors (DTSs) to hold training at all the depots (“PTSB Shop Gates”).
Maintaining the Improvements • AGM Committee meets weekly. • Identifies short- and long-term solutions for issues. • Identifies modifications to policies and procedures. • Performs campaign tracking and updates. • Depot management conducts a Quality Control check geared towards PTSB cases. • 10 buses are checked per day at each depot. • “Report Card” audits held at each depot. • At the end of the audit, all depot management personnel ride a bus to look at it from the customer’s point of view. • Customer Services conducts audits of PTSB issues at each depot to ensure that critical safety campaigns are completed. • Bus Merger Team conducts quality audits. • S.O.
