How to do code review without slowing the team down
Good code review does more than catch bugs. Speed it up with small changes, clear expectations and automation.
Technical debt is a software decision that buys speed today and costs something tomorrow. Debt taken on knowingly is a tool; the problem is debt nobody knows about.
How does technical debt become visible?
The most reliable signals come from daily team work rather than the code: how many files a small change touches, how many fixes follow a release, and how long a new person needs to get productive. Tracking these for a few months beats intuition.
Which debt should be paid first?
Debt in modules that change often and carry critical business rules comes first. An ugly piece of code nobody has touched for years can usually wait. A simple rule: multiply change frequency by failure impact and sort the list.
How do you fit repayment into the roadmap?
A separate clean-up project usually gets cancelled. Add a small debt-reducing step to each feature in that area instead. For larger structural changes, write a short note that explains cost and risk to the business in numbers.
Is a rewrite the answer?
Usually not. Business rules hidden in the old system get lost in a rewrite. Protecting behaviour with tests and replacing module by module carries much less risk.
