Rich Lopez, aka the “QuantrixAuthority”, Creates YouTube Channel for Quantrix Users

We are always amazed and gratified by our customers’ passion for Quantrix Modeler, but Rich Lopez has taken it to the next level. By day, he works in the finance department of Litehouse Foods, but by night he is YouTube star The Quantrix Authority. His series of three- to five-minute-long how-to videos helps others get the most out of using Quantrix’s multidimensional modeling software, from learning how to snap two matrices horizontally to a canvas, to the benefits of using Timeline for recursion in a model.

How did you get started with Quantrix?

I was introduced to Quantrix when I worked at clothing retailer Coldwater Creek. I used it to build an allocation tool to manage inventory at our 350+ stores. When I moved to Microsoft’s interactive entertainment division, a co-worker and I built a distribution model to ensure that we were getting the Xboxes and games shipped properly. It was during some of the really big

Microsoft launches, like Halo 4 and Windows 8, so we build scenarios for everything we had to manage during the holiday season. We were able to model it down to the daily levels. Quantrix saved my bacon at that job – I could not have done what we needed without it. Now I use Quantrix for financial modeling and capacity modeling for Litehouse.

What inspired you to start making video tutorials about Quantrix Modeler?

I leaned a lot about using Excel from a guy on YouTube called MrExcel. Bill Jelen has more than a thousand videos, and I used to watch him every day. I am a pretty advanced Excel user, but I love Quantrix more. After seeing what MrExcel has done, and seeing how his expertise helped me, I thought I could do something similar to help others with this fantastic software.

How do you choose the topics?

My first video was about the first feature I learned in Quantrix – “Using As.” My mentor taught me that when I started at Coldwater Creek, and it’s basic functionality in Quantrix. Some people at my company are struggling to use certain features of our Quantrix Models, so I’m starting to create videos on topics that will help them.

Who are you targeting?

I am pretty much reaching out to beginners and intermediate users. I am very open to questions – after my second video, I got an email from a Quantrix user in the Ukraine. Just this week someone asked me about using DataLink with .csv files, so I made that video. Whenever someone asks me a question, I try to answer it.

How many videos do you plan to make?

MrExcel has more than 1,000 videos and a forum that everyone knows. I have eight videos online now, and if I get to 100, I know I will have really accomplished something.

I’m following you on Twitter. How famous are you?

Ha ha! On a scale of one to ten, I am probably a “one” in real life. But in the Quantrix world, I hope to one day be about an eight! I am having fun with the videos, and with my Twitter account (@QuantrixAuthor). I have legitimate Quantrix users following me, and I feel like I am rubbing shoulders with some real legends. Some of these people are such power users, and they are telling me to keep making videos. Their feedback is so positive, and it’s great.

Final question – what was your “aha” moment using Quantrix?

It happened at Microsoft. I remember being called into a room by eight managers and having them tell me they needed some specific information, and they wanted it in three days. It could not be done in Excel, so we just pounded out a model in Quantrix. I stayed up until two in the morning a couple of nights, but I developed a model where if the managers wanted to add another distribution center, product line, or launch scenario they just could select a category and hit “enter”. That was it. And I realized then and there that Quantrix Modeler was the coolest tool that has ever been made. Quantrix Forever!
