“Mariusz demonstrated exceptional knowledge and skills, helping us not only improve warehouse operations but also reorganize our entire company. Thanks to his support, we developed a new organizational structure, optimized production processes, and implemented key procedures that significantly increased the efficiency of our business.
One of Mariusz's greatest strengths is his outstanding ability to observe and analyze. He is able to identify both potential problems and untapped opportunities, and his recommendations are always thoughtful and supported by specific actions. Additionally, Mariusz proved invaluable in training our team in soft skills, which translated into improved collaboration and internal communication within the company.
I highly recommend Mariusz and External Project Management to anyone seeking an expert in process optimization and organizational development. His professionalism, dedication, and effectiveness make working with him a genuine added value for any business.”
“It is worth recalling the words of Jerzy Grotowski, a world-renowned director and innovator, who said, ‘A company is created by people.’ This statement perfectly reflects our experience working with Mariusz Prusiel and External Project Management. His exceptional ability to see potential risks and identify new opportunities, as well as his vast experience and fresh perspective, allowed us to quickly set the right direction for our growth.
Thank you very much for our cooperation so far—I look forward to our continued mutual success!”
“After a thorough analysis, it became clear that the disorder in our warehouse was merely a symptom of our previous approach—we operated somewhat reactively, without a structured plan.
It was only through Mariusz’s support, helping us streamline our processes, build a more robust organizational structure, and identify and empower key employees, that we experienced a genuine breakthrough. This enabled us not only to reorganize our warehouse but also to reach a point where every team member clearly understands their responsibilities.
I highly recommend Mariusz to anyone looking for expert support in streamlining processes and taking their business to the next level.”
