Case Study: Aunt Bessie's achieves up to 47% OEE improvement and major cost savings with Idhammar Systems' OEE & CMMS

Aunt Bessie - Customer Case Study

Aunt Bessie's is a fast‑growing UK frozen‑food manufacturer producing millions of items daily. Facing rising input costs, retailer margin pressure and the need for greater flexibility, the company launched a Continuous Improvement programme in 2004 that used Overall Equipment Effectiveness (OEE) to identify losses, drive culture change and prioritise improvement work.

Aunt Bessie's implemented the Idhammar OEE system and complementary CMMS to enable drill‑down analysis, user‑friendly shop‑floor ownership, predictive maintenance, spares control and TPM initiatives. Over 12 months OEE improved between 14% and 47% on key lines; the firm estimates each 1% OEE gain is worth about £150,000 per year, the system paid for itself within months and delivered reduced stoppages, better resource use and clear profitability gains.
