Executive Summary

Problem

AnKo Planen was already recording all of its customer calls, but lacked a structured process for evaluating the data. As a result, quality management, coaching, and employee development were largely based on isolated spot checks and subjective assessments.

Solution

Within two weeks, DACH AI Solutions developed an AI-powered quality assurance system that automatically transcribes every customer call, anonymizes personal data in compliance with GDPR requirements, evaluates the conversation against predefined quality criteria, and visualizes the results in a central management dashboard. The first 436 analyzed calls already provided a reliable data foundation for coaching and quality management.

Result

Based on current call volumes, approximately 2,700 customer calls are now analyzed automatically each month—with ongoing operating costs of only around €125. This transformed a collection of previously unused call recordings into an objective management tool for quality assurance and employee development.

Key Insights

Many companies already record their customer calls. Data collection was never the real problem.

The actual bottleneck was making that data economically usable.

This project demonstrates that AI does more than replace manual analysis. It makes implicit experience and knowledge measurable, standardizes the entire quality assurance process, and creates a reliable data foundation for continuous improvement through coaching, employee development, and process optimization.

Starting situation

AnKo Planen GmbH employs approximately 30 to 50 people, including six to eight customer service employees.

Around 2,700 customer calls are handled every month. These range from product consultations and quotation requests to inquiries about individually manufactured products.

Although all calls were already being recorded, there was no structured evaluation process.

The company had neither an objective scoring system nor a consistent data foundation for measuring call quality or identifying targeted coaching measures.

A complete manual analysis of every conversation would not have been economically viable.

Process Overview

  1. 1

    Call Upload

    New call recordings are imported automatically.

  2. 2

    Transcription and GDPR-Compliant Anonymization

    Each conversation is transcribed, and personally identifiable information is automatically anonymized.

  3. 3

    AI Analysis

    Every call is evaluated against seven predefined quality criteria. The AI also identifies the reason for the call, the course of the conversation, customer sentiment, and potential areas for improvement.

  4. 4

    Data Storage

    All results are stored in a structured format in PostgreSQL and Google Sheets.

  5. 5

    Dashboard

    A central management dashboard visualizes all relevant metrics in real time.

Results

Before the automation was introduced, customer calls were recorded but provided the company with very few actionable insights.

Today, every conversation is analyzed automatically.

Management can immediately see which issues customers are actually contacting the company about, which employees have development potential in specific areas, and how call quality changes over time.

Instead of relying on isolated spot checks, the company now has a complete data foundation for quality management and employee development.

Business Value

Before the automation was introduced, call quality assessments were largely based on experience, individual observations, and occasional spot checks.

Today, management can objectively track developments across all customer calls and focus coaching measures on the areas where they have the greatest impact on call quality and customer satisfaction.

The AI does not replace the team leader. It provides the team leader with a complete basis for making informed decisions for the first time.

A comparable manual evaluation process would require approximately 130 to 180 working hours per month and generate personnel costs of around €3,300 to €4,400.

The automated system performs the same task for ongoing operating costs of approximately €125 per month.

Qualitative Value

The automation creates an objective foundation for quality management for the first time.

Every customer call is evaluated according to the same criteria and can be compared across employees, time periods, and reasons for contact.

In addition to measuring call quality, the system also reveals why customers are contacting the company and which topics place the greatest demand on the customer service team.

This creates better coaching opportunities while also generating valuable insights for product development, internal processes, and the customer service operation as a whole.

For the first time, we have an objective foundation for employee development. We knew there was potential for improvement, but the dashboard showed us exactly where it was. Product knowledge and how conversations are brought to a close are now our two clear priorities.

Frequently Asked Questions
