How can real customer tasks help you assess whether an AI service is useful?

Start by defining what customers need to accomplish

When testing an AI service, asking “Do you think it is intelligent?” often yields little guidance for specific improvements. A more useful approach is to ask participants to complete practical tasks, such as finding instructions for their device, understanding the scope of a service, or contacting a human when the system cannot answer.

Building on public discussions at CES about trust and transparency in intelligent content, this article offers an independent testing method. Small-scale testing can uncover problems, but it cannot, on its own, prove that all customers will have the same experience.

Select tasks from business records

Work with sales, customer service, and product teams to compile common questions from real customers. Obtain the necessary authorization and remove sensitive information before using these records. Select tasks of varying complexity, including questions that public information can answer and those that require further verification or human assistance.

For each task, specify the customer's starting point, goal, and necessary background, without telling participants where to click or which keywords to use. For example: “You need to find out whether the service covers brand naming. Find the relevant information and decide what to do next.”

Ask the person responsible for the business area to prepare reliable reference materials and record the applicable versions and limitations. Do not use an answer previously generated by AI as the sole reference answer, or assess success against company commitments that have not yet been confirmed.

Observe the process as well as the final answer

Ask participants to complete tasks independently. Observe whether they understand where to start, can ask questions, recognize the basis for answers, and find the next step. Record their actions, hesitation, misunderstandings, and attempts to correct mistakes. Do not immediately take over when they encounter difficulties.

Test how the system behaves when it cannot answer, misunderstands a request, or lacks sufficient information: can customers recognize that a result is uncertain, and can they consult relevant materials or contact a human? When a handoff is involved, check whether the advisor receives the necessary context that the customer has permitted to be shared.

Cover actual usage environments, including mobile and desktop. Where necessary, check keyboard operation, network interruptions, and situations where human support is offline. Participants should not be asked to provide real passwords or unrelated sensitive information.

Turn findings into specific improvements

Group observed problems into categories such as inaccurate information, hard-to-find entry points, unclear prompts, inability to correct errors, and failed handoffs. Record the task, the conditions under which the problem occurred, its impact, and the person responsible. Prioritize problems that could mislead customers when making important decisions.

For example, if participants cannot find the scope of a particular service, first check whether the information on the official website is clear, then check whether the assistant is using the correct version. Rewriting the answer alone may not resolve an outdated source. After making fixes, retest with the original task and similar tasks.

If certain types of questions cannot yet be handled reliably, clearly explain the limitations and provide a practical route to human assistance, rather than hiding errors to increase the proportion of cases resolved automatically.

Evaluate continuously and maintain clear boundaries

After launch, schedule reviews informed by customer feedback, human advisors' input, and error logs. When product versions, service scope, or knowledge materials change, retest the affected tasks. Handle test records involving privacy or business information in accordance with the company's actual authorizations and management rules.

Focus on whether customers complete tasks smoothly and accurately, rather than comparing only response speed or conversation counts. Qingmei Future can assist with designing testing processes and interfaces; the company remains responsible for business facts, access permissions for materials, and the final service.

Before testing, agree on who will organize the findings, who will confirm business facts, and under what circumstances automated responses should be paused. When retesting, retain the task conditions and results from before and after the changes to avoid mistaking an interface change for a resolved problem.

For unresolved issues, record the scope of their impact and how they will be handled by people, so customers and staff assisting them know how to proceed.
