KMRL has always been at the forefront of innovation,

leveraging technology to improve operational efficiency and
service reliability. One of the latest advancements in this

pursuit is the in-house development of the Q-MMS (QR-Based
Maintenance Management System) app. Built using the Flutter

platform with Google Drive as its cloud storage solution, the Q-

MMS app is a significant step towards digitalising and
optimising the maintenance workflow of Kochi Metro’s assets.

A Digital Leap in Maintenance Management

The Q-MMS app is designed to streamline and enhance the efficiency of
maintenance scheduling, execution, and tracking. By integrating QR code scanning,

the system enables quick access to asset-specific maintenance history and
instructions, ensuring timely and accurate interventions. Key features of Q-MMS

include:

1.QR Code-Based Asset Identification: Each asset is tagged with a unique QR
code, allowing technicians to instantly retrieve maintenance records by scanning

the code.
2.Task Scheduling & Tracking: The Maintenance Team Officer (MTO) can schedule

maintenance tasks, which are then displayed to supervisors and technicians
based on priority and status.

3.Google Drive Integration: The app syncs in real time with Google Drive,

facilitating seamless data storage and retrieval for asset details, maintenance
schedules, and feedback.

4.User Authentication & Role Management: Different user privileges ensure secure
access for technicians, supervisors, and reviewers.
