Another important fact is that the data science and engineering team needs to work about twice as long as the application engineering team. Think about it this way. If you are developing a Maps product, the maps application engineering team might be about 4 engineers who work for an year to build the product. However the maps data teams will be about 8 people and will work for two years to create and operationalize the first version of the product.
If you are a product manager involved in planning a data product, this is a good insight to share with your stakeholders and investment decision makers. This of course is a rough idea based on data products in the healthcare industry.
