Experience and knowledge
Our vision is to create an application that establishes the current condition of a manufacturing operation, sets aspirations and accelerates the improvement process
About Us

As senior executives and particularly as a result of our interim assignments, we have amassed a great deal of knowledge and experience in how to accelerate the financial, operational and cultural performance of a manufacturing business. Having had success leading; growth, transformation, transition and turn around we have identified recurring traits that if left unchallenged, disconnect operations from their obligations to the financial performance of the business. The Operations function is responsible for both converting sales orders into revenue and controlling over 60% of business costs meaning that any disconnection is damaging. Linking operational performance to the financial wellbeing of the business is the foundation of our assessments. They have been designed to help you understand and improve aspects of your operation that have a significant influence on performance but can be difficult to monitor.

The Development of OAG Assessments

Originally designed for single-site manufacturers, investors and consultants, it soon became apparent that multi-site manufacturers, recruiters and membership organisations could also benefit from a multi-site, multi-layer version. There are currently 3 types of OAG assessments available, all of which establish current state and aspirations for manufacturing site or sites based on the 7 key components. They produce a report highlighting areas for improvement and detailed actions to enable you to achieve your aspiration

OAG Assessment Methods
