A business application solution architect should have what level of expertise in the Dynamics 365 apps?

Having an awareness of the various Dynamics 365 apps and their primary use is essential for a business application solution architect. This level of expertise allows the architect to understand how the different applications within the Dynamics 365 ecosystem can work together to provide comprehensive solutions for a business's needs.

Knowledge of the primary functionalities and strengths of each app enables the architect to recommend the best tools and features for specific requirements, facilitating better decision-making and strategies for implementation. This broad understanding equips the architect to identify opportunities for integration and customization, ensuring that businesses can leverage the full potential of the Power Platform and Dynamics 365 solutions effectively.

In contrast, expert level in all apps may not be practical; while a deeper knowledge about specific applications can be beneficial, it's not necessary to possess expertise in every single app. Specialization in one app can limit the architect's ability to provide holistic solutions, and having no knowledge at all would result in significant gaps in understanding how to create effective and aligned business applications.
