A consultant can help if there is lots of data within your organization, but it's difficult to get them into a report or dashboard. Data visualization consulting services (https://datalance.net/data-visualization) can assist in determining which metrics are important, structure dashboards and recommend alternative visualization methods to better communicate the trends. This is particularly important when reporting has become complicated, or various departments use a variety of formats. It's important to have a couple of business questions in mind going in to the engagement. This provides a specific problem to resolve, and allows the consultant to better assess whether the dashboards are effectively assisting users.
