A/B Testing Module for Retail Feature Change Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Retail businesses face challenges in measuring the impact of changes such as product price, location, or availability across stores, especially in competitive markets with diverse customer expectations, as existing methods fail to accurately identify comparable stores and validate feature changes effectively.
Innovation Solution
Implementing a computing device-based testing module that uses Dynamic Time Warping (DTW) for time series clustering to identify comparable sister stores and perform A/B testing to determine statistically significant changes, allowing for data-driven decision-making on rolling out feature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional store comparison methods are used, then store reconfiguration can be performed, but measurement precision of feature change impact is insufficient
Solution Approach 1:
The patent replaces traditional mechanical/store-based comparison methods with a computing device that executes algorithmic processes. The computing device performs A/B testing calculations, statistical significance tests, and time series clustering to objectively measure feature change impacts, eliminating the imprecision of manual or heuristic comparison approaches.
Solution Approach 2:
The patent introduces a computing device as an intermediary between store feature changes and impact measurement. This intermediary executes sophisticated algorithms including A/B testing frameworks, statistical analysis, and time series clustering to bridge the gap between raw store data and actionable insights about feature change effectiveness.
2Adaptability or versatility
If store reconfiguration is performed to address diverse customer expectations, then adaptability improves, but difficulty of detecting and measuring feature change impact increases
Solution Approach 1:
The patent segments the complex task of measuring feature change impact into distinct analytical components: A/B testing for controlled comparison, statistical significance testing for reliability assessment, and time series clustering for pattern recognition. This segmentation allows each aspect to be measured independently and systematically, reducing the overall difficulty of detection and measurement.
Solution Approach 2:
The computing device serves as an intermediary that handles the complexity of detecting and measuring feature change impacts in adaptive environments. It processes diverse store data, applies multiple analytical methods simultaneously, and synthesizes results into clear measurements of feature change effectiveness, making the complex measurement process manageable.
3Measurement precision
If A/B testing with statistical analysis is implemented, then measurement precision of feature changes improves, but device complexity increases
Solution Approach 1:
The computing device is designed with multi-functionality, serving as a universal platform that performs A/B testing, statistical significance analysis, time series clustering, and result visualization all within a single system. This consolidation reduces the need for multiple separate tools while maintaining high measurement precision through sophisticated analytical capabilities.

AI summary
Systems and methods for determining whether a particular feature or change implemented in at least one test store causes a significant change as compared to one or more control stores are discussed. More particularly, techniques for using a time-series clustering algorithm to identify comparable sister stores to a store in which a feature change is being considered are described. Once the sister stores are identified a testing module can perform an A/B testing so as to validate whether a particular feature change being implemented in the test store causes a significant change as compared to the control stores.
