The team

Within the Operational Insights team we know the roles product owner, scrum master, analyst, data engineer, infra specialist and MicroStrategy specialist. Our common goal is to make data work, our customers and candidates.

The team is responsible for the Management Information System of our client.

Our data engineers integrate and transform the data from the different systems and then load it into our data warehouse. Accuracy, completeness and timeliness are paramount, with the performance in mind. If the data is in our data warehouse, our MicroStrategy specialists will create the semantic / schema layer, the attributes and the metrics. The result is a self-service environment for creating reports and dashboards. In addition, we develop standard reports and dashboards that are used throughout the organization.

Note: at this moment the team is in a bumpy phase due to the time limit on phasing out the Oracle module
