The challenge

Samworth Brothers, the family-owned food group behind brands including Ginsters and Soreen, operates across meals, sausages, savoury pastry, food to go, sliced cooked meats and cake. Each operating company reported its own results using its own calculations, definitions and process, and bringing those submissions together for the group executive board required a substantial monthly Excel exercise consuming around a week of each cycle.

Analysts estimated that around 80% of their time was spent gathering, cleaning and preparing data rather than interpreting it, limiting the time available to answer the commercial questions that mattered: which categories were gaining or losing momentum, how the group compared to the wider market, and which competitors were driving growth. A later data quality review also identified reporting errors that had previously gone unnoticed.

What we changed

Following a competitive tender, Optia brought together five external sources (NielsenIQ EPOS, Kantar, Dunnhumby, Sakana and Nectar) with internal category submissions to create a single, maintained view of the GB market. The model standardises definitions and calculations across all six categories, allowing like-for-like comparison. During the transition, users could switch between the new standardised calculations and the previous methodology to build confidence in the new approach.

The resulting Power BI dashboard covers total GB market performance, individual category analysis, retailer performance, and competitor benchmarking against 16 strategically relevant names including Greencore, Cranswick, Pilgrim's, Compleat Food Group, Pukka Pies and Finnebrogue. It is delivered into Samworth's own Power BI tenant with SharePoint ingestion, so the group keeps control of access, governance and distribution.

As part of implementation, Optia carried out a structured data quality review across source files, calculations and outputs, identifying several previously undetected reporting errors, which were investigated, corrected and incorporated into the new standardised process.

The results

Samworth Brothers now has one board-ready view across six operating categories: a single reporting model replacing manual Excel consolidation, consistent calculations across all six categories, and category, retailer and competitor performance visible together. Samworth Brothers reports reclaiming around a week from each monthly cycle. The first working version was delivered and demonstrated around three months after the initial discovery discussion.

In their words

“We were going to go and create another chart, which seems crazy in today's world. The dashboard is brilliant, this is exactly the kind of thing we needed. Seriously, thank you so much for the effort and everything that you put into this, and using your brains and your knowledge and your experience to create it.”
