A client once asked for a small update: “Just add three extra fields on this screen.”

Sounds easy. But that one change meant:

• Updating database structure
• Modifying APIs
• Adjusting validations
• Changing reports
• Handling existing data

What looked like a 10-minute UI tweak turned into a full system-wide update. And this happens all the time.

Because in software, nothing lives in isolation.Every small change has ripple effects. The problem isn’t the request. It’s the assumption that it’s “simple.”

Good products are built when both sides understand the impact, not just the interface.
