Equipment Complaint Management App

The largest and only electric utility provider in Malaysia is on a mission to take all operations mobile. This powerful mobile app helps TNB employees to manage and track complaints, and communicate their resolution with vendors seamlessly. A sophisticated back end system with dashboards, complaint management workflows and reports helped them achieve their goal with GoodCore.


About Client

Tenaga Nasional Berhad (TNB) is the largest electric utility company in Malaysia. Listed on the main board of the Malaysian stock exchange with almost RM 99.03 billion (GBP 18.5 billion) in assets, the company’s 34,900+ employees serve an estimated 8.4 million customers in Malaysia. TNB’s core businesses are focused on the generation, transmission, and distribution of electricity.


Project Details

GoodCore developed a complete end-to-end Complaint Management System for TNB's distribution department that allows them to keep tabs on complaints about purchased equipment and then track the vendors responsible for the faulty equipment. The mobile application also enables users to upload multiple images along with their complaints so that the administrators receive complete information regarding the complaint.

A sophisticated back end system with dashboards, complaint management workflows and reports was developed to help them manage complaints and associated vendors better.
