What are the benefits of partnering with external data consultants versus building an in-house team?

External consultants bring specialized expertise and a fresh perspective that may be difficult or costly to replicate in-house. They can offer rapid deployment of solutions and access to a broader range of tools and best practices. Building an in-house team often requires significant time and resources for recruitment and training.
