I’ve been trained professionally for doing both quantitive and qualitative research, there are some projects that I've been done by different methodologies:
Rapid usability test
When customers bought our hard-ware product, they need to install them to landline in their home, and go on website to complete some settings.
As the process has too many breakpoints, my job is to optimize the quick guide trying to help them successfully install our product.
Besides single form of interview, I would like to apply with ux tools, like 'divide the dollar', 'design sprint' to execute interview.
Workshop is a good way to align team's direction, also it's necessary to include different perspectives from different professions. My job is to execute the workshop from start to the end, gathering ideas and finding insights from generalized results.
