What does keeping the lights on (KTLO) mean?

"Keeping the lights on" (KTLO) refers to activities that maintain a digital product's functionality and performance. This includes fixing bugs, performing maintenance, and managing technical debt. KTLO is essential for product sustainability but can detract from innovation if overemphasized. Strategies to balance KTLO with innovation include dedicating team members or time to KTLO tasks, maintaining high test coverage, and addressing technical debt proactively. Effective KTLO management allows product teams to focus on creating value while ensuring long-term product viability.
