Mark Raheja, Pitney Bowes Inc. / Digital Cement, Director of Experience Planning, May 2010.

Just wanted to thank you for the exceptional work in taking the group through your findings today… They found it very useful and informative…  Great job!

Ilona’s attention to detail is truly mind-boggling.  She forces my head to think in different ways, which is not always an easy task. This exercise is well worth the effort. The outcome is a product that far surpasses what was initially designed.


Evan Jones, Founder, Stitch Media, Producers of Interactive Site for CBC TV Show, Dec 2007.

Ilona helped us take an objective look at the hard work we’d accomplished for The Border: Interactive and the Mobile Contest.   She taught us to throw out the bathwater (cluttered & inconsistent design, confusing language) but still keep our baby (the project’s intended goals, artistic vision).  Her constant defense of the little guy (‘our user’) made sure this project succeeded.  Since it’s launch it has been three times nominated for national awards and won the Banff World Television Award for Mobile Enhancement.


Julie Saulnier, Usability Team Lead, Bell Web Solutions, Professional Services, July 30, 2007

Ilona Posner worked for us as a consultant.  Her responsibilities included creation of a test plan, conducting usability tests, writing the report, and presenting the results to the client…. She showed a high level of professionalism and was instrumental in the success of the project…. I highly recommend Ilona for any Usability position or endeavor that she may seek to pursue.


Dmitri Buterin, Founder and CEO, BonaSource Inc., Recommendation from LinkedIn, Sept 2006

Client: Dmitry hired Ilona as a Business Consultant in 2005 and hired her more than once

Top qualities: Great Results, Expert, Good Value
I have worked with Ilona on a several joint projects and highly recommend her. She is very practical and results oriented, works very quickly and efficiently.  I am very impressed with her ability to extract meaningful conclusions from user interviews and come up with specific usability recommendations.


Eric Schaffer, Founder and CEO, Human Factors International, June 5, 2003

I have the highest regard for your skill and intelligence.
