Experience across the boundaries where business problems become complicated.

The company provides the framework through which selected senior advisory, business analysis, commercial and project-based assignments are undertaken.

Bob Mazzei’s professional career began in 1987 and has included independent business engineering, business analysis, commercial development, IT and systems, project and product management, procurement, data analysis, quality and management systems, professional education and international business relationships.

Experience includes work involving the United Kingdom, the European Union, the United States and wider international business relationships, with particular exposure to agrifood, logistics, technology, professional services, medical and orthopaedic environments, construction and operational businesses.

Sienda does not try to be everything to everybody. Assignments are accepted where experience, independence and practical involvement can genuinely contribute.

Founder, business engineer, strategist — and unofficial tea critic. Also a writer, with a worrying amount of rock music in the background.
