MASS-analytics helped us to improve our MMM process. A 3-day course covered the whole MMM project process as well as technical part of it on types of models and forecasting and optimisation parts. We have better understanding now what is important for a successful project. MASS-analytics gave us a great support with MassTer software as well us on how to schedule the process and how a presentation should look like. I can with confidence say that, as an agency, we have improved our MMM project delivery and can do more advanced modelling now.
