Tech Debt for Non-Technical Stakeholders

I've seen technical debt in various forms. Here's a realistic look at when it's justified, when it's not, and what it means for your project.

What is Technical Debt, Really?

Technical debt is the future cost you incur by choosing an easier or cheaper solution now instead of a more robust approach. It's not always bad, but it always has consequences.

The Only Good Reason for Technical Debt

Deliberate Choice: This is when you consciously decide to take on technical debt as a calculated risk. You fully understand what you're saving now and what you'll have to pay later. This might happen when:

  • You need to test a market quickly with a MVP (Minimum Viable Product)
  • You're facing a critical deadline that justifies the future cost
  • You're building a temporary solution while planning a more robust one

In these cases, the debt is a strategic decision, not an accident or oversight.

How Technical Debt Often Happens

  1. Rushed Planning: Skimping on design and architecture discussions to start coding sooner. This often leads to major refactoring later.

  2. Cost-Cutting Hires: Hiring less experienced developers because they're cheaper. While they might get the job done, the code quality often suffers.

  3. Mismatched Skills: Assigning developers to projects outside their expertise to save on hiring specialists.

  4. Skipping Best Practices: Foregoing code reviews, proper documentation, or automated testing to save time upfront.

  5. Short-Term Business Pressure: Pushing for quick launches to meet market demands, often at the expense of code quality.

  6. Legacy System Constraints: Being forced to build on top of outdated systems.

  7. Lack of Knowledge Transfer: When key developers leave, their undocumented knowledge goes with them.

These reasons often lead to unintended technical debt.

Real Consequences

  1. Exponential Slowdown: What starts as small time-savers can lead to weeks of extra work later.

  2. Increased Bugs: Poorly structured code is harder to understand and more likely to contain errors.

  3. Spiraling Costs: The money saved initially often pales in comparison to the cost of fixing issues later.

  4. Developer Turnover: Good developers often leave projects drowning in technical debt.

  5. Security Vulnerabilities: Rushed code or outdated systems are prime targets for security breaches.

  6. Reduced Agility: Your ability to adapt is compromised.

  7. Customer Dissatisfaction: Slow updates and buggy features can drive customers away.

Managing Technical Debt

  1. Make Deliberate Choices: If you're going to take on technical debt, do it consciously and with a clear plan to address it later.

  2. Quantify the Debt: Try to estimate both the short-term savings and the long-term costs of your decision.

  3. Set a Repayment Plan: If you take on debt deliberately, schedule time to address it, just like you'd plan to repay a financial loan.

  4. Prioritize Wisely: Focus on addressing unintended debt that's actively hindering progress or posing security risks.

  5. Educate Stakeholders: Help non-technical decision-makers understand the long-term impacts of short-term savings.

  6. Regular Audits: Periodically assess your codebase to distinguish between deliberate and unintended technical debt.

  7. Improve Processes: Implement practices that reduce unintended debt, like proper planning, code reviews, and documentation.

Deliberate technical debt is a tool. Unintended technical debt is a trap. Know the difference, and plan accordingly.
