The Challenge

Institutional Knowledge Trapped in Closed Tickets

IT support organizations accumulate enormous institutional knowledge through their ticket history — thousands of resolved issues representing tested solutions to real problems in the organization's specific environment. Yet this knowledge is effectively inaccessible: buried in closed tickets that can be searched by keyword but not semantically queried or synthesized.

When a new ticket arrives, an experienced agent might remember resolving something similar six months ago and know exactly where to look. A new agent, or an agent unfamiliar with that system, starts from scratch — researching external documentation, asking colleagues, or escalating unnecessarily.

The result is inconsistent resolution quality across agents and shifts, longer resolution times, and repeated escalations for issues that have been solved multiple times by different agents who never shared their solutions.

Key Pain Points

Historical ticket knowledge inaccessible beyond keyword search
New agent onboarding taking weeks to build institutional knowledge
Inconsistent resolution quality across agents and shifts
Unnecessary escalations for previously-solved problems
Knowledge siloed in individual agents' memories
The Solution

Living Knowledge Base with Semantic Ticket Retrieval

We built a specialized RAG system that ingests an organization's historical ticket database — including ticket descriptions, resolution notes, agent comments, and time-to-resolution data — and makes this knowledge semantically searchable in real-time.

When a new ticket arrives, the system retrieves the most semantically similar historical resolutions, ranks them by relevance and recency, and presents a synthesized resolution recommendation to the handling agent. The agent sees not just one past ticket but a synthesis of the 5-10 most relevant past cases — with the most critical steps highlighted.

The system continuously improves: as new tickets are resolved and marked successful, they're automatically ingested into the knowledge base — creating a virtuous cycle where the system gets smarter with every ticket closed.

Our Approach

1
Historical ticket ingestion from ServiceNow, Jira, Freshdesk, and Zendesk
2
Semantic embedding of ticket descriptions and resolution notes
3
Hybrid retrieval with recency and resolution quality weighting
4
LLM synthesis of multiple historical cases into actionable recommendations
5
Confidence scoring with evidence from specific past tickets
6
Automatic ingestion of new resolutions for continuous learning
