Looks like the article was in 2019.
Also, the end user (Mitsu) would not want to give competitors a tip on the IPQA they should be looking at. Recently I was working on a software development project where the company I worked for sought out to improve the cost estimation accuracy and reduce the time to do an investment screening for projects greater than $150 million. The avergae size is in the $300 million range. We bought a license from a start-up for their program that improved Cost estimation accuracy from +/-50% to +/-20% and reduced the time to come up with the cost estimate from 6 months to 1 month. So this is a game changer. We can beat all our competitors by 5 months in providing a project cost estimation and on top our price is way more accurate. The company I worked for never mentioned the software or the company, which is now going on to 3 years. We do not want our competitors to know what we are using and what enhancements we did to the program. We do not want to do any papers, articles or case studies because we want to maintain our lead. I see the same thing happening with PrinteRite3D.
