Description du stage:

At Mass Analytics, Marketing Mix Modeling (MMM) projects are conducted following a predefined process based on the well known CRISP-DM process.

This six-phase process, starts with setting the foundations of the project by accurately and thoroughly understanding the business requirements discovering the available data. After that comes the crucial data preparation phase where the data is processed and transformed into the required format. This phase is also culminated by a data check milestone to confirm the accuracy of the data with the different stakeholders.

After building the model and validating it, the project outcomes are reported to the client. In this final and important step, the project outcomes are delivered to share insights and actionable recommendations. The model is consequently deployed to help optimize future marketing budgets and improve KPI's.

The Marketing Analytics summer internships will focus on the Data Preparation and Project Delivery steps. Two very important phases in the CRISP-DM process that require essential skills that should be acquired and harnessed by any successful data analyst wishing to work on modelling at a later stage.
