Rory Masureik

Rory Masureik

Senior Management Consultant

Rory joined Goldratt UK in 2026, bringing more than 25 years of international experience across complex manufacturing environments, including aerospace and defence, automotive, chemicals, fibres, food, and medical devices.

His work focuses on helping organisations achieve significant and sustainable performance improvements by improving flow, increasing throughput, and building internal capability. He combines deep operational experience with a systemic approach to problem solving, enabling organisations to identify and manage their constraints effectively.

Rory was introduced to the Theory of Constraints (TOC) early in his career, having trained directly under Eli Goldratt in 1999. Since then, TOC thinking has remained a foundational element of his approach to improving organisational performance, particularly in environments where complexity obscures cause-and-effect relationships.

He has led and supported major transformation initiatives globally, including operational turnarounds, digital manufacturing programmes, and enterprise-wide improvement efforts. His experience spans both line leadership and advisory roles, allowing him to work effectively with executive teams while remaining grounded in the realities of day-to-day operations.

A distinctive strength of Rory’s work is his ability to align Operations, Technology, and Continuous Improvement around a common goal. By bridging these disciplines, he helps organisations move beyond local optimisation and achieve coordinated, system-wide performance gains.

He believes that most operational challenges are not caused by a lack of effort, but by constraints and policies that limit flow. Once identified, these can be addressed systematically to unlock significant performance improvements.

Rory is particularly passionate about developing internal capability. He works closely with leadership teams to ensure that improvements are not only delivered, but sustained, enabling organisations to continue improving long after the initial intervention.

He holds a professional qualification in Industrial Engineering and has further training in Lean Manufacturing through a technical scholarship in Japan. He is also a certified ADKAR Change Management practitioner and an active contributor to Industry 4.0 and Manufacturing Operations Management (MOM) working groups.
