Evolve, Don't Abandon: The Perils of System Overhaul

Engineers often underestimate the time required for migrating from an old system to a new one, leading to significant project delays and complications. Supporting the legacy system during this transition is essential, yet many project managers face frustration when they hear that no new features can be developed for prolonged periods.
