Hellenic Dairies S.A. x WITSIDE

Project Overview

HELLENIC DAIRIES S.A. is the largest Greek dairy company, active in 48 countries with a strong portfolio of consumer-focused brands including Olympos, Rodopi, Tyras, and Kliafa. With a legacy of excellence and innovation since 1985, the company offers a wide range of dairy, plant-based, organic products, juices, and soft drinks.  

To maintain its market leadership and increase customer satisfaction, HELLENIC DAIRIES partnered with WITSIDE to accelerate its digital transformation, modernize demand planning, and create a more agile, cost-efficient supply chain adapted to an ever-evolving market landscape. 

Client's Challenges & Needs

As a leader in the fast-moving dairy sector, HELLENIC DAIRIES faced critical challenges such as managing short shelf-life products, forecasting demand for new SKUs without historical data, and minimizing losses from overstock or stockouts.  

External disruptions like COVID-19, limited product history, and unpredictable promotional impacts further complicated forecasting.  

The company needed an intelligent, adaptable system that could simulate scenarios, incorporate real-time variables like weather or market trends, and improve overall supply chain responsiveness, while supporting its expansion and customer-centric mission.
