I am a test engineer at a high tech company in San Francisco bay area. I have been developing Labview automation routines for several years but mostly in the academic sector. I am new to the industry environment. I have had multiple arguments with one of the Engineering Managers about using Labview in final production tests on devices and on sending customers Labview GUIs to interface, control, and automate their tests and equipment with our products. He says that Labview is very slow and nobody uses Labview in production settings. He also thinks that sending customers Labview GUIs is unprofessional. He prefers GUIs written in C language.
I wanted to see what's your thoughts on that and if there is an article or a reference I can cite to convince him otherwise
