Tell me about a tech debt you introduced and the consequences of it what's the trade-off options in front of you
Question Explain
This question is trying to gauge your awareness about the concept of technical debt and your decision-making process in situations when you had to introduce it. Technical debt refers to the cost of choosing an easy solution instead of taking a better approach that would take longer. The question requires you to explain a situation where you consciously had to introduce technical debt, the repercussions it had, and the trade-off options you had at your disposal.
In your response, include:
- The context or scenario in which the technical debt was introduced.
- The reason why the technical debt was chosen.
- The aftermath or consequences of those decisions.
- The other options available and why you did not go for them.
Answer Example 1
In one project I was involved in, we had a very tight deadline to deliver a new feature. The best practice or the most efficient way to implement this feature would have taken longer than the time we had. Therefore, I made the decision to go for a quicker, but less efficient solution, thus introducing a technical debt.
The aftermath of this decision means that sometime in the future, we will have to revisit this feature to optimize it. The consequences of this are increased accumulated work for future iterations due to the temporary solution. The alternative option we had was to push back the delivery date to fully implement the feature perfectly, but considering the business requirements, it wasn't an option at that time.
In hindsight, my decision did allow us to meet our deadline and kept the project on track, but it was a compromise. Learning from this experience, I now always weigh the long-term implications before introducing any technical debt.
Answer Example 2
In a previous role, we were working on an update to our app. We had a fast approaching deadline and not all the code could be refactored to the desired state before publishing. We had to choose between delaying the launch or accruing technical debt. We chose the latter.
The consequence of accruing this technical debt was that it led to taking more time for later software updates as the code needed to be improved. It also increased the risk of bugs in the system. However, it was a calculated risk to maintain business continuity.
The other possible trade-off was to postpone the release and spend more time refactoring. This would have reduced future software maintenance time significantly. But considering the competitive market and the urgency to stay ahead, we chose to go with accrued technical debt."
