Frequently asked questions

How do you quantify technical debt?+

Estimate the share of engineering time lost to working around poor code, multiply by the team's fully-loaded hourly cost and hours worked, and annualise it. That wasted spend is the carrying cost of the debt.

How do I justify a refactor to management?+

Frame it financially: show the annual cost of the current drag, the one-time remediation cost, the reduced drag afterwards, and the payback period in months. A clear ROI wins budget far better than 'the code is messy'.
