The research says probably yes The alert volume isn't imaginary — but be careful which numbers you cite The fix: batch the routine work, protect the calendar The important exception: not everything can wait for the batch A more honest way to estimate the ROI The takeaway Sources The Real Cost of Context Switching: What Security Alerts Actually Do to Developer Flow Companies keep investing in better frameworks, tighter deployment gates, and broader platform suites — and feature delivery keeps getting slower anyway. For engineering leaders trying to explain that paradox to the board, the usual suspects (headcount, tooling, talent) rarely hold up. The more useful place to look is something less visible: how often developers get pulled out of what they're doing, and what it costs them to get back in. As "shift-left" security practices spread, developers absorb a steady stream of vulnerability alerts, automated pull-request comments, and one-off Jira tickets throughout the day. The goal — a more secure codebase — is the right one. The delivery mechanism is often the problem. Scattering fixes across random moments in the workday erodes productivity without necessarily making the codebase safer any faster. The alternative a growing number of engi
