Coaching and Mentoring Services

Opus Magnum was created in 1982 in Calgary, Canada and initially served the local business community with system analysis and design services and systems development. In 1986 the training branch was added. Courses and workshops were delivered to universities and businesses across Canada dealing with systems analysis and design, requirements management, and business process design.

In 1992 the company expanded into the US and provided coaching and mentoring across North America. The US company was formed in 1997

In 2011 the UK company was opened to service its US clients with branches in the UK and has steadily increased its UK client base by providing coaching and mentoring services to all sizes of business from individual startups to large corporations.


Peter began his career as a project management specialist, he worked for a few years with construction projects and during this time developed a passion for systems and methodologies. Peter continued his education in Information Technology and trained in system development and business analysis.

The evolution of small computers created a niche for systems in small and medium businesses and Peter started his own software development company. Peter was able to use his analysis and design skills to create solutions for many different types of business.

Peter was invited to teach at two universities. This led to the growth of a training business where he developed courses and taught business analysis, system design, and project management subjects, also providing coaching to large and small organisations around the world.

The Best in the Business

I have been both a student and contractor of Peter’s training services and his manager. Peter did a wonderfully effective job of developing and implementing a full business requirements methodology. He was able to define and adapt an approach that accommodated the unique concerns and interests of the culture but delivered high quality results. Peter also developed and delivered training on requirements  development, requirements elicitation, system analysis and project management that uniformly received extremely positive reviews and results. Lastly, Peter did an outstanding job of developing his direct reports to provide valuable mentoring and coaching support for the staff. I would welcome the opportunity to work with Peter in the future.
I’d heartily recommend Peter for his expertise and skills!
