I began working with Q3 a few years ago as company was producing a new product. Over this time we have had three development and QA teams working closely together. During this time we communicate via phone, email and Skype on a daily basis. Our work together has been a great experience.
One of the highlights has been working with the Project Manager. He is a very effective communicator, asks great question for finalizing requirements and gives regular and open status reports. On the times when things have slipped by 1-2 days, the Project Manager and his team have worked on the weekend to help keep the schedule in check.
We all have enjoyed our collaboration and highly recommend Q3.
