Hi, I’m Chris Klein, Flow-Cal’s Customer Support Manager. Prior to joining Flow-Cal, I spent 10 years in Space Shuttle Flight Software focusing on software development, testing and requirements. I came to Flow-Cal in 2011 as the Quality Assurance Manager where I implemented a number of agile software development processes, improving the testing framework. These changes allowed us to identify defects early on in the process which ultimately increased customer satisfaction. I’m bringing to the support department what I’ve learned in quality assurance to ensure customer satisfaction at another level. I invite you to meet the rest of the support team. Please don’t hesitate to call or email us anytime.
