Bob Mazzei
Senior Business & Commercial Advisor
Business engineering. Commercial intelligence. Project, product and decision support.I work with business owners, executives and organisations when they need an experienced independent view on a difficult decision, problem, project or opportunity.I help understand what is really happening, identify what matters, challenge assumptions and turn complexity into practical decisions.

WHAT I DO
My work usually begins where a problem does not fit neatly into one discipline.A commercial decision may also involve operations, technology and data. A certification requirement may require processes, responsibilities and documentation to be redesigned. A struggling project may actually have a business problem rather than a project-management problem.I work across those boundaries.Typical assignments include:Business engineering
Processes, organisation, workflows, operating models, inefficiencies and management systems.Commercial & market decisions
Markets, products, competitors, channels, pricing, opportunities and international business development.Project & product review
Independent assessment of projects, products, requirements, priorities, feasibility and direction.Technology advisory
Understanding what a business actually needs before deciding what to buy, build, automate, integrate, change — or avoid.Data & decision analysis
Turning fragmented information and business data into conclusions management can understand and act upon.Standards, certification & regulatory implementation
Turning external requirements into workable business processes, responsibilities, controls, documentation and evidence. This may include areas such as GLOBALG.A.P., ISO frameworks, privacy and data protection, and EU AI Act requirements.
Experience
My professional career began in 1987.Since then I have worked across business engineering, commercial management, software analysis, project and product management, data analysis, technology and professional education.My experience includes agrifood, construction, medical and legal environments, professional services, technology and other B2B activities.I have worked with businesses and organisations in the United Kingdom, Italy, Spain, North America and other international markets, and have managed commercial relationships across much of the world.I have also taught business, technology and applied problem-solving to thousands of people, designed professional courses and directed a school of informatics and technologies.In 2012 I founded Sienda Ltd in London.
how I work
I do not begin with a predetermined solution.I listen, investigate, examine the evidence, challenge assumptions and try to understand the problem before recommending what should happen next.Sometimes the answer is to change something.Sometimes it is to simplify something.Sometimes it is to stop doing something that no longer makes sense.And sometimes the correct advice is not to proceed at all.My value is not in selling a particular product or methodology. It is in bringing independent judgement to the problem in front of me.I am not looking to sell software, subscriptions or packaged solutions. I work directly on the problem.
