CALL CENTER MYSTERY SHOPPING
Thorough evaluation of response speed, language use, listening skills, and problem-solving from a customer's perspective. Surveyors experienced in evaluating various phone services—customer support, order centers, and help desks—make calls using real customer scenarios to quantify response quality. Confidential call-record reports contribute to CS improvement, operator training, and outsourcer quality management.
Get a Free QuoteA mystery call service where surveyors posing as regular customers call call centers, customer support lines, and corporate phone desks, objectively evaluating response speed, language use, listening skills, problem-solving ability, and closing.
Phone service is a company's "voice identity" and directly impacts customer satisfaction and brand image. However, supervisor monitoring alone has limitations, and accurately understanding the actual customer experience is difficult. Mystery callers making calls as real customers can evaluate operators' "natural responses."
Results are scored across 6 axes—response speed, first impression, listening skills, information accuracy, problem-solving, and closing. Reports include chronological call records and improvement suggestions, serving as concrete training materials for operator education.

Call Center Mystery Shopping
Experience and evaluate the full phone service process—connection ease, first impression, greeting style, listening attitude, question response, hold handling, and closing.
Evaluate different operators through multiple calls, quantifying individual strengths and weaknesses. Clearly identify training points needed to raise the entire team's performance.
Not just phone—we evaluate multichannel customer service quality under unified criteria including email inquiries, chat support, and social media DM responses.
We solve your concerns about call center and phone service quality through mystery shopping.

Ongoing complaints about "cold service" and "being passed around." Monitoring shows no issues, but want to understand why customers feel dissatisfied.

Large quality gap between veteran and new operators. Want quantified comparison data to identify specific training points.

Many calls are transferred or passed around, leading to low satisfaction. Want to understand how much is actually resolved on first contact.

Call center operations are outsourced; want third-party verification that contracted quality levels are being met.

System metrics are available but want to experience firsthand how long customers actually wait when calling.

Quality varies across phone, email, and chat channels. Want unified standard comparison and evaluation.
Here are actual case studies from call center mystery shopping assignments we have conducted.

Phone support scored low in customer satisfaction surveys. Surveyors called with 5 scenarios—product inquiries, return requests, delivery issues—and evaluated 6 axes: response speed, first impression, listening, information accuracy, problem-solving, and closing. Call records and improvement proposals were compiled into a confidential report.

The client wanted objective evaluation of 30 operators to identify priority training areas. 60 mystery calls were made (2 per operator) across 3 scenarios—policy inquiries, claims consultation, and cancellation requests. Individual operator scorecards and rankings were created.

Call center operations were outsourced to 3 companies, and the client wanted third-party SLA compliance verification. 10 monthly mystery calls were made to each company over 3 months, comparing answer rate, wait time, response quality, and first-call resolution under unified criteria.

The client wanted to improve phone inquiry service quality for residents. Surveyors called as residents with 8 inquiry scenarios—taxes, registration, facility use—evaluating clarity, transfer frequency, and service politeness.

カスタマーサポートの品質は顧客のロイヤルティに直結しますが、SVのモニタリングはランダムサンプリングに限られ、顧客が実際に体験している電話対応の全体像を把握するのは困難です。
実際の顧客シナリオ(商品問い合わせ・返品・クレーム等)で電話をかけ、応答速度・傾聴力・情報の正確さ・問題解決力・フォローアップまで一連の対応を評価します。

コールセンター業務を外部委託している企業にとって、委託先のサービス品質が契約基準を満たしているかの検証は重要な経営課題です。内部モニタリングだけでは客観性に欠ける場合があります。
委託先のコールセンターに一般顧客として電話をかけ、SLAの遵守状況・応対品質・一次解決率・顧客満足度を第三者の立場で客観的に評価。複数委託先の比較データもご提供します。

電話だけでなくメールやチャットでの顧客対応も増えていますが、テキストベースの応対品質はモニタリングが追いつかないケースが多く見られます。返信速度・文面の適切さ・解決力に課題を感じている企業が増えています。
実際にメール・チャット・SNS DMで問い合わせを行い、初回応答速度・文面の丁寧さ・情報の正確さ・問題解決力・フォローアップまでテキスト対応特有の評価項目で調査します。

電話・メール・チャット・SNSなど複数チャネルで顧客対応を行っている企業では、チャネルごとの対応品質のばらつきが顧客体験の一貫性を損なっている可能性があります。
同一の問い合わせ内容を電話・メール・チャット等の複数チャネルで実施し、統一された評価基準で各チャネルの対応品質を比較。チャネル間の品質ギャップを可視化します。

“They verified our operator service quality from an outside perspective. The detailed feedback on call flow, honorific usage, and hold times revealed points we had overlooked with internal monitoring alone.”
“We used this to understand our call center's service level. With scenarios separated for order-taking through complaint handling, the report content was concrete enough to immediately incorporate into improvement measures.”
“We commissioned this as a phone service quality check. The evaluation of hard-to-quantify aspects like "voice tone" and "response timing" was excellent. We realized there were many things overlooked due to familiarity internally.”
There has never been a single report of detection since our founding. Surveyors call naturally like regular customers. Call content and speech patterns are pre-scripted to avoid being unnatural.
Surveyor-side call recording is not performed. Surveyors take notes in real-time and create detailed chronological records of the call after completion.
