Research in the industry is generally faster and tend to be more successful. I would attribute many factors to the difference in performing research in the industry vs. academia. As per the lecture notes, the main reason for research in industry is money, therefore there are more funds being invested to drive research and results. Another difference is that research progress in the industry is measured based on performance which is measured consistently and accurately throughout the project. An industry scientist is expected to deliver accurate results quickly working in a very fast work pace. This is not the case in academia, there is no structure to measure performance and the researcher receives very little feedback, and projects can be dragged for years despite insignificant progress is made just because the project is attached to long-term grants so funds must continue to come in.
