When is Ignoring Technical Debt Acceptable?
While the negative impacts of technical debt are real, it is not always necessary, or even practical, to address it immediately. There are a few scenarios where it makes sense to let debt accumulate. For example, if the cost of addressing technical debt is significantly higher now than in the future, if the debt is not impacting your immediate and short-term business needs, or if you have an emergency release like a major security vulnerability fix. Keeping the big picture in mind when making the right tradeoffs is critical, and well-managed technical debt can be an effective tool to shorten the lead time, allowing for the prioritization of important deployments.
This brings us to a key point: the context that separates “good” technical debt, which lets us ship, and “bad” technical debt, which needs attention. This separation comes down to understanding the actual impact on customers and the team. Ignoring some technical debt isn’t so bad after all, so long as you have shared context to guide your decisions.
When Ignoring Technical Debt Becomes a Challenge
Managing Technical Debt
- Identify the types of debt: Not all technical debt is created equal. Distinguish between the debt you accept at the moment as something to fix later on and the inadvertent debt you discover.
- Analyze and automate: Analyze the origins of your debt and look for ways to tighten workflows or automate certain tests and processes. This can help reduce common errors and hidden bugs, preventing them from snowballing into technical debt.
- Develop new policies and standards: These should clarify when debt makes sense and when it causes unacceptable damage. For instance, releasing an immediate security patch could be considered acceptable, while allowing errors that will eventually cause considerable downtime would not.
- Communicate the cost: It's crucial that decision-makers and the DevOps team understand the implications of technical debt on product quality and developer retention. When another high-speed deadline comes your way, ensure that these key stakeholders are aware of the risks. If they fully understand the potential cost, they might be more likely to adjust delivery dates or provide funding for additional developers.
