Placing a Ward on the Service: Introducing the Service Status Visualization Project 'Pink Ward'

Kakaopay Securities developed Pink Ward, a service status visualization project, to clearly grasp service status from the customer's perspective beyond technical monitoring. Previously, there was a problem where identifying the impact of an incident, confirming the responsible party, and writing incident reports consumed a lot of manual work and resources.

Pink Ward aims to automate the entire process from incident detection to identifying the responsible party, summarizing communications, and writing reports. In particular, it is designed to use natural language instead of technical terms, so that non-developer roles such as the customer center can easily understand the service situation.

The system operates in conjunction with internal platforms such as WECAN (metadata management), Chunsiri (an LLM chatbot based on Amazon Bedrock), Grafana, and OpenSearch. The key features are as follows:

• Automatic Incident Registration: Detects incidents via webhook and automatically invites relevant personnel to a Slack channel.
• Status Visualization: Shows the real-time status of service units perceived by customers, such as accounts and orders, through a dashboard.
• AI-Based Automation: Periodically summarizes Slack conversation content, and after an incident ends, uses an LLM to automatically generate a draft incident report and postmortem.
