INSIGHT

Software Architect Varied Roles

A software architect's role varies widely across organizations and can be hands-on or purely managerial.
Their impact spans infrastructure, cross-team collaboration, and organizational compliance matters like GDPR.

INSIGHT

Architects Guide, Teams Decide

Software architects influence technology choices by providing guidance rather than issuing mandates.
Teams retain ownership of implementations to ensure buy-in and retain talented staff.
