Success story

Data quality system for anomaly detection in healthcare survey studies

This case study details the development and implementation of a quantitative analysis and statistical anomaly detection system for a research organization, aimed at improving data quality and reliability.

01. Problem

Our client needed a robust solution to ensure the quality of data collected during their research studies, especially those involving surveys conducted by non-specialist interviewers. Human error and potential interviewer bias could compromise the integrity of the data. To address this, it was essential to implement a quantitative analysis and statistical anomaly detection methodology to identify and mitigate data quality issues.

02. Solution

We developed an additional component to the client’s existing survey system that aggregated and analyzed the collected data to detect anomalies. We seamlessly integrated it into their infrastructure and used open-source big data solutions to perform statistical analysis and generate detailed reports. These reports were then presented to the research teams, allowing them to quickly identify and correct data anomalies.

03. Results

Implementing this solution significantly improved data quality standards within the research organization. By ensuring more reliable and accurate data, the organization was able to produce more credible and impactful research.

We are very pleased with our partnership with Stratoflow and, as we continue to grow, we expect to increase the numbers of developers that work with us on our projects. They have proven to be very skilled and flexible. They're extremely reliable, and they have a very good company culture of their own, which gives them a real edge compared to other providers that serve more as production shops rather than thought partners and creative problem solvers.

Travel sector rebound after the pandemic is complete. We have fantastic global coverage of travel data distribution due to mutual agreements and data exchange between aggregators. Competition for the best price of limited resources degradates margins.

How to win? Provide personalized experience and build your own products in the front-office. The missing bits: a traveller golden record collecting past activities and a AI/ML recommendation technology.
