We began the project with a series of scoping and design workshops, to understand and document all the requirements. The scope ranged from Gross Sales down to Profit before Overheads, across all e-Commerce models: B2B, B2C, D2C. Our understanding of Unilever systems enabled us to collect source data, and a rate per selling unit was calculated for each P&L line. This was then applied against the POS sales given by customer and SKU, and where needed, by factoring alternative business rules and capability to create virtually unlimited override calculations to manage the complexity in an understandable and traceable way. With an agile project approach, the solution is being constantly updated to reflect current priorities and changes in the e-Commerce environment, while maintaining traceability to allow audits and decisions to be made with confidence.
