Government legacy systems are some of the oldest and most critical software in existence. Modernizing them without disrupting millions of people requires a different approach.
Why Big Bang Modernization Fails
Government IT history is littered with high-profile modernization failures. The pattern is consistent: trying to replace everything at once creates a complexity and risk profile that no program can manage. The agencies that have succeeded have done so by rejecting the big bang in favor of incremental approaches.
The Human Capital Dimension
Legacy system modernization is as much a human capital challenge as a technical one. The engineers who understand the existing systems are often nearing retirement. Capturing that institutional knowledge before it walks out the door is as important as any technical migration work.
