Incident automation for a large telecommunications firm in Asia

The challenge

One of Asia’s leading telcos that receives about 25K+ customer service emails a month was struggling to increase the efficiency of their customer support and satisfy customers’ issues with better response and resolution time. They needed a solution that could use AI/ML models to remove the delays in the incident ticket journey, eliminate errors such as incorrectly classifying incidents, and minimize the engineer’s troubleshooting time.

The solution

Addo built a customized incident management platform based on two core AI modules – no-incidents detection & filtering, and root cause localization – with the goal to achieve the following:

  • Automatically classify customer emails and incident tickets via agents, and direct them to the right engineer. 
  • Identify the incidents and learn from historic tickets to resolve them faster.

Our approach was three-fold. Firstly, to filter out all the no incidents, secondly, to use the historic data to determine root causes of the incidents and thirdly, to auto-resolve the issues. 

We realized that no incidents constitute around 40% of the tickets, so as the very first step, we used state-of-the-art ML and AI techniques, such as Time series analysis, rule base engine and decision tree to filter them out and close them without any human intervention. Once we were left with only the relevant incident events, we used Deep Learning models such as neural networks to determine the top 3 probable root causes of the incidents based on the historic data and allocated them priority scores and confidence levels. Lastly, an automated heal trigger AI Engine was built and integrated with the client system to auto-resolve issues by generating relevant triggers for the hardware/software. 

To build this solution, a pool of highly skilled Machine Learning Consultants, Machine Learning Engineers, Data Engineers and Integration Engineers were engaged. 

The results

As a result, a significant increase in net promoter scores for customers was observed. Simultaneously, the misallocation of resources and incident resolution time was highly reduced as the engineer’s work for root cause analysis was automated.

ML techniques used:

  • Word2Vec and Doc2Vec for Feature Engineering
  • Deep Neural Networks
  • Ensemble Methods (SVM, Gradient Boosted Trees)
