Understanding Customer Effort Score

Customer Effort Score (CES) measures how easy — or difficult — it is for a customer to resolve an issue or complete an interaction with your support team. The concept is straightforward: customers who have to work harder to get help are less loyal and more likely to churn, regardless of whether their issue was ultimately resolved.

CES is typically captured with a single post-interaction question: "How easy was it to resolve your issue today?" — rated on a scale from "Very Difficult" to "Very Easy."

Why CES Matters More Than You Might Think

Research by CEB (now part of Gartner) popularized the idea that reducing customer effort is more strongly correlated with loyalty than delighting customers. In other words, eliminating friction is often more valuable than adding perks. For call centers, this insight is transformative — it shifts focus from going "above and beyond" toward making every interaction simple and frictionless.

Common Sources of Customer Effort

Before you can reduce effort, you need to understand where it occurs. The most common culprits include:

  • Repeating information: Customers having to re-explain their issue after being transferred.
  • Multiple contacts: Needing to call back because the issue wasn't resolved the first time.
  • Long hold times: Waiting on hold adds perceived effort even if the outcome is positive.
  • Complex IVR navigation: Too many menu options before reaching a human agent.
  • Unclear next steps: Customers unsure what happens after the call ends.

How to Reduce Customer Effort: Key Strategies

1. Optimize Your IVR Flow

Audit your IVR regularly. Reduce menu depth, use plain language, and always offer a clear path to a live agent. A customer who reaches a human quickly will report significantly lower effort than one who navigates five menu levels.

2. Enable Context Transfer Across Channels and Transfers

When a call must be transferred or a customer returns through a different channel, make sure agents can see the full prior interaction history. Screen pops in your CRM that display the customer's account and recent contacts eliminate the dreaded "Can you tell me your account number again?"

3. Invest in First Contact Resolution

Every callback a customer makes represents a failure to resolve their issue — and doubles their effort. Identify the top reasons customers call back within 7 days and build targeted interventions: better agent training, updated knowledge bases, or revised policies.

4. Proactive Communication

Many inbound contacts are caused by uncertainty — customers calling to check on an order status, a payment, or a scheduled repair. Proactive outbound notifications (SMS, email) that update customers before they feel the need to call reduce inbound volume and effort simultaneously.

5. Simplify Processes, Not Just Conversations

Sometimes high effort is baked into business processes — a refund that requires three approval steps, or a password reset that involves multiple verification methods. Work cross-functionally to streamline the processes that generate the most customer contacts.

Measuring Progress

Track CES by contact reason, channel, agent, and team. Look for outliers — contact reasons with consistently high effort scores often signal a broken process, not just a poorly performing agent. Combine CES data with call recordings and verbatim customer comments to build a clear picture of where friction lives.

The Link Between Low Effort and Business Outcomes

Reducing customer effort is directly connected to retention and revenue. Customers who describe an interaction as low-effort are more likely to repurchase, less likely to share negative feedback, and less likely to defect to a competitor. Measuring and actively improving CES is one of the highest-leverage activities a customer experience leader can undertake.
