Root cause analysis

Root cause analysis is the practice of tracing a symptom, such as a spike in complaints, back to the underlying process, policy, or product defect that produced it. The alternative, resolving each ticket in isolation, never stops the symptom from recurring. Established methods include 5 Whys (repeated questioning to reach the originating cause), fishbone (Ishikawa) diagrams (mapping possible causes by category), and Pareto analysis (isolating the small number of causes driving most of the volume). In CX, this starts with clustering tickets by theme, then tracing the largest theme to its source. OnClarity’s Voice of Customer automates this by surfacing root causes directly from feedback. Grubhub uses it to turn feedback into insights that shape its roadmap. The real test of success is recurrence: a fix that addresses the root cause should stop the issue from reappearing.

Customer insights

Customer insights are conclusions about customer behavior and needs that are specific enough to act on. They differ from raw feedback, which is simply what a customer said, and from analytics, which shows what happened in aggregate. A customer insight explains why something happened and what to change next. Customer insights come from combining feedback, conversation data, usage data, and survey responses across channels. The step that matters is classifying patterns by root cause, not just counting volume. Example: a spike in refund-related tickets across chat, email, and reviews first looks like a support volume problem. Root-cause classification shows most of those tickets trace back to a single checkout error. OnClarity’s Voice of Customer surfaces that root cause automatically and pushes the finding into Slack, Jira, or Linear. The product team that owns the checkout flow gets the ticket directly, instead of support agents closing the same complaint one at a time for weeks.

Topic clustering

Topic clustering groups conversations by theme to size the drivers behind contact volume, without requiring an analyst to define categories in advance. Because clusters emerge from what customers actually said, the method surfaces new issues that a fixed intent taxonomy would file under a generic other.

Voice of customer

Voice of customer is the discipline of turning reviews, support tickets, surveys, and conversations into operational decisions. The distinguishing feature of a working programme is the closed loop: findings reach the team that can fix the cause, and the resulting change is measured against contact volume.

Closed loop feedback

Closed loop feedback is the practice of acting on individual customer feedback and reporting back to the customer about what changed as a result. It operates on two levels. The inner loop is where a team responds directly to the customer who gave the feedback, typically within a defined service window. The outer loop is where the underlying theme is routed to whichever team can address the root cause. Closing the loop requires three things: a named owner, a deadline, and a reply to the customer. OnClarity’s Voice of Customer pushes daily reports, feedback topics and bug insights into Slack so themes reach the right owner without manual handoff.

Support teams are no longer a cost centre.
