ERD Table and Field Questions
According to the annotations in your ERD diagram, I understand that:


A Client may have many Projects
A Project may have many Designers


If that is true, then these 2 tables should not be consolidated.

Likewise, depending on your definition of WhyClientChoseUs and ClientLossReason, there are reasons to keep both.  (E.g. you may have a reason WhyClientChoseUs and later need to add the ClientLossReason.  Not uncommon on big projects.)

But, because the client may continue with one project but abandon another, the Project may be a better place to keep that information.

But answers to these kinds of question do depend on your definitions.
