Global Business Services (GBS)

The need for speed of delivery in Shared Services (Finance, HR…….) in the recent years has refocused this area to closely link with IT and robotics (RPA). In Finance, achieving best in class financial services is not possible without streamlined processes with Lean methods. Business Process Outsourcing (BPO) touches every company that is looking for efficiencies.

Manufacturing and Energy

This is a key sector due to its economic impact on the whole society. Its complexity involves both manufacturing and service element, for both individual and industrial consumers. With the growing focus on consumer services, the sector has increased focus on IT and big data that require lean processes.

Information Technologies (IT)

IT sector has been quick to respond to dynamic changes of customer requirements. Continuous improvement to product design and customer experience are traditional quality areas that ensure market competitiveness.

FMCG (Fast Moving Consumer Goods)

In this sector the optimised speed and operational efficiency is the key to success. Process flows, accuracy of delivery, efficiency of procurement and supply chain are typical areas for improvement that quality methods help dramatically and quickly improve.

OEM (Original Equipment Manufacturer)

Producing microelectronics, semi-conductors, manufacturing automotive parts, etc. is a growing industry. Accuracy, precision, focus on detailed and correct measurements and production leave no space for errors and reworks. It is one of the areas where six sigma level of quality is just a pre-requisite to be on the market. Getting better than that is what we can help achieve.
