Manufacturing in the United States is in trouble. That's bad news not just for the country's economy but for the future of innovation.
National Instruments has gathered customer information and data regarding some of the cost differences between building a custom solution versus using NI off-the-shelf tools. Using this data, we built the Graphical System Design ‘Build vs. Buy’ Calculator. The calculator can help show the financial differences between building a custom solution versus buying an off-the-shelf system. This paper discusses the benefits and drawbacks of both a traditional custom design approach and off-the-shelf embedded tools.
