You are a developer at a startup company that has just released a new service. During development, you made suboptimal coding choices to keep the project on schedule. You are now planning your next two weeks of work, which you decide will include implementing a feature the product manager wanted in the initial release but was postponed to a release occurring soon after the initial release. You also include time to refactor code that was introduced to correct a bug found immediately before the planned release date. That code blocks the worst impact of the bug, but it does not correct the flaw. Revising that suboptimal code is an example of what?
