Introduction

This paper presents a detailed analysis of the vehicle maintenance process in a car rental scenario through the use of activity diagrams. The first diagram (Figure 1) captures the current process, highlighting the roles, steps, and flow of activities involved in maintaining rental vehicles. The second diagram (Figure 2) proposes an improved process, incorporating management feedback and process optimizations aimed at enhancing efficiency, reducing paper documentation, and increasing managerial involvement, particularly that of the Maintenance Manager.

Current Vehicle Maintenance Process (Figure 1)

The current vehicle maintenance process begins when a vehicle becomes due for maintenance based on usage or time interval. The process commences with a Data Entry Staff member logging the maintenance request into the Facility Management System (FMS). This step involves recording relevant details about the vehicle and the maintenance needed. Subsequently, the process involves the Assistant Manager or the Manager who reviews the request, plans the maintenance schedule, and assigns it to a technician. The technician then performs the maintenance activities, records the completion details, and updates the FMS accordingly. Post-maintenance, the vehicle is checked for quality assurance, and a report is generated to confirm that the vehicle is ready for rental again. The current process heavily relies on paper-based documentation at various stages, and the Data Entry Staff plays a pivotal role in data transcription and record-keeping. Roles such as the Assistant Manager and Manager primarily oversee and approve activities, with limited active involvement in the day-to-day maintenance tasks. Moreover, customer complaints filed via the ‘Rental Online Complaints’ (ROC) software are not reformatted before entering the system, which complicates record management andFollow-up processing.

Improved Vehicle Maintenance Process (Figure 2)

The optimized process modifies the existing workflow by eliminating the Data Entry Staff, granting the Maintenance Manager more direct involvement, and streamlining information flow. Customer complaints filed through ROC are reformatted before being entered into the FMS, enabling better tracking and response. The process begins directly with the Maintenance Manager reviewing the maintenance requests generated automatically from the system or customer reports, thus removing intermediate manual data entry stages. The Maintenance Manager allocates tasks to technicians, who perform maintenance and update the system digitally, reducing paper documentation. The involvement of the Assistant Manager or Manager in routine maintenance oversight is minimized, focusing instead on managerial oversight and exception handling. The process emphasizes real-time updates, with use of digital forms and reports. This approach enhances efficiency, reduces the use of paper documents, and ensures quicker response to customer complaints and vehicle issues. The system design emphasizes active manager engagement and leverages technology for better process control and customer satisfaction.

Discussion

The transition from the current to the improved process demonstrates a focus on digital transformation, process streamlining, and managerial empowerment. Removing the Data Entry Staff and reassigning roles to the Maintenance Manager facilitates faster decision-making and reduces redundancy. Reformating customer complaints ensures consistency and clarity for subsequent processing. Digital documentation minimizes waste, aligns with modern business practices, and offers expedient access to records. The proposed activity diagrams provide a clear visual map of these workflows, assisting management in understanding and implementing operational improvements.

Conclusion

Activity diagrams serve as effective tools for analyzing and redesigning business processes within the car rental industry. By illustrating the current and improved vehicle maintenance workflows, organizations can identify inefficiencies and implement targeted improvements. The key enhancements include eliminating unnecessary roles, digitizing records, and increasing managerial involvement to achieve higher efficiency and customer satisfaction. These visual representations are instrumental in communication, training, and strategic planning, ultimately contributing to better operational outcomes.
