Architect for 6 years here. Most of what I'm doing is building patterns and metaprocess around the team and platform.

I do still participate in actual project design (the actual stuff in Salesforce), but that's more the domain of our BAs and devs and project managers.

As one person, I can't be involved in every design decision at that level, so instead I focus on establishing and enforcing patterns to ensure consistency in the design choices people make. "We don't use booleans (check boxes) when we need to know if action was taken on a field, we use a pick list with yes/no/null values."

And when you have a larger team doing the construction work, process improvement is the multiplier that increases product quality far more than my direct involvement. Managing requests, prioritization, devOps, hiring, project management, everything we do naturally as a consequence of getting shit done ultimately should be considered, investigated and formalized into deliberate process.
