"As part of our Lean Six Sigma training program, our business has incorporated SigmaXL as a Statistical resource to our trainees. We have been doing this for a number of years. There are two key points I would like to make: 1. The software has a capability equal to many other more expensive Stats software programs and with its link to Excel makes it a very learnable program, basically all of our students pick up the applications with ease. 2. The service provided by the team at SigmaXL is second to none and this has included the fantastic experience in our relationships with the customer service guys at SigmaXL but also the senior leadership team of SigmaXL and where necessary a timely reply and comment from the CEO. This is absolutely top class. Keep up the great work, cheers"
