I worry that every level has this misunderstanding, that "Salesforce" is a monolithic system that can be remade if only we pass a comprehensive test suite. Salesforce does not have 80k+ developers making a singular monolithic product. They have 80k+ employees servicing the sales demands of a massive number of customers. Excel is a perfectly fine CRM if you only have a handful of customers.
Hope you're staying sane in the SaaS landscape. I hear a lot of horror stories.
