## The Challenge

##### Drowning in Data, Starving for Insights

Three years ago, Lebara found itself at a crossroads. Despite being in the telecommunications business for over two decades, the company was struggling to harness the true power of its data. The challenges they faced included:

- **Manual Data Validation:** Teams spent countless hours manually checking data quality, often finding issues only after they reached downstream business users.
- **Lack of Trust**: Business leaders were hesitant to rely on data, often reverting to gut feeling for critical decisions.
- **Reactive Problem-Solving**: The data team was constantly putting out fires, with little time for strategic initiatives.
- **Limited Scalability:** As data volumes grew, manual processes simply couldn’t keep up.

## The Solution

##### Embracing Automation and AI to Drive Trust in Data

Recognizing the need for a complete overhaul, Lebara embarked on an ambitious data transformation journey.

Their strategy focused on three key pillars:

- **Modernizing Infrastructure**: Moving from on-premises systems to a cloud-based Databricks architecture.
- **Leveraging AI and ML**: Implementing machine learning models to drive personalized customer interactions.
- **Automating Data Quality**: Partnering with Anomalo to automate data quality monitoring at scale.

## The Results

##### A Data Quality Success Story

The impact of Lebara’s data quality journey has been remarkable:

- **Proactive Issue Detection**: An estimated 80% of data issues are now caught before they impact the business.
- **Efficiency Gains:** Time spent on data quality issues dropped from roughly 70% to less than 30% of the data team’s workload.
- **Improved Customer Experience**: AI-driven communications, powered by high-quality data, now account for over 80% of customer interactions.
- **Faster Resolution:** Root cause analysis time reduced from days to minutes.
- **Increased Data Trust:** Business leaders now confidently make data-driven decisions, knowing the underlying data is reliable.
