Creating a new way to generate retail valuations

Data business supplying the automotive industry with used car pricing and technical information
With dealers’ margins coming under increasing pressure, cap wanted to create a completely new methodology for generating their published Retail Values – one which responded to the used car market more closely, and would assist dealers in finding the pricing ‘sweet spot’.
The eventual solution was an automated daily feed into cap’s core product, and included multiple processing steps:
- Clean & validate data
- Clustering algorithm to define broad segments of vehicles
- Decision tree to predict Retail Value
- Evaluate all scored values against 20+ business rules
- Adjust values where significant variance from business rules occurs
- Publish values to daily product
3 consultants delivered a large-scale data processing platform using the Microsoft BI stack.
Data mining structures, reporting cubes and an ASP.net application to manage the process and analyse the output.
The solution pulls and processes around 700,000 live adverts before completing approximately 4 million price points, every day.
Price points are rigorously tested against a wide range of business rules, adjusted where necessary and then published into cap’s Black Book products.
Delivering the project, although critical, wasn’t the end of it. We also helped cap find analytical people, recruit them and set up an analysis team to support the ongoing maintenance and extension of the solution.
