Technical debt represents the implied cost of future rework caused by choosing expedient solutions now instead of better approaches that would take longer. This document outlines a structured approach to identifying, measuring, prioritizing, and systematically addressing technical debt across Bayat projects.
Technical debt can be categorized into several types:
- Deliberate/Tactical: Conscious decisions to optimize for short-term delivery
- Inadvertent/Accidental: Debt that arises from mistakes or lack of experience
- Environmental: Debt caused by changes in the external environment (e.g., outdated dependencies)
- Architectural: Structural issues that affect the entire system
- Code Quality: Specific implementation issues (e.g., duplicated code, complex methods)
- Test Debt: Insufficient test coverage or poor test quality
- Documentation Debt: Missing, outdated, or inadequate documentation
- Infrastructure Debt: Outdated or non-optimal infrastructure components
- Process Debt: Inefficient or missing development processes
- Time Constraints: Pressure to deliver quickly
- Resource Limitations: Insufficient staffing or expertise
- Business Priorities: Short-term business needs overriding technical concerns
- Knowledge Gaps: Lack of expertise in particular technologies
- Changing Requirements: Frequent or significant changes to requirements
- Technology Evolution: Rapid changes in technology landscape
- Growth and Scale: System requirements growing beyond initial design
Technical debt can impact projects in various ways:
- Reduced Velocity: Slower feature development over time
- Increased Defects: Higher rate of bugs and production issues
- Decreased Reliability: More frequent system failures
- Onboarding Challenges: Difficulty bringing new team members up to speed
- Developer Frustration: Team morale and retention issues
- Security Vulnerabilities: Increased security risks
- Scalability Limitations: Inability to handle growth
- Code Analysis: Static and dynamic code analysis tools
- Architecture Reviews: Structured evaluation of system architecture
- Retrospectives: Team feedback sessions
- Developer Surveys: Gathering insights from development teams
- Performance Monitoring: System performance metrics
- Change Impact Analysis: Measuring the effort required for changes
- Technical Radar: Regular assessment of technology components
Each technical debt item should be documented with:
- Description: Clear explanation of the issue
- Location: Affected components or code areas
- Type: Category of technical debt
- Origin: How and when the debt was introduced
- Impact: Effects on quality, performance, or development
- Remediation Options: Potential approaches to address the debt
- Effort Estimate: Approximate work required to fix
- Risk Level: Potential negative consequences if not addressed
- Code Quality Metrics: Complexity, duplication, test coverage
- Maintainability Index: Calculated from various code metrics
- Change Failure Rate: Percentage of changes causing failures
- Lead Time: Time from code commit to production deployment
- Mean Time to Recovery: Time to recover from failures
- Technical Debt Ratio: Ratio of remediation cost to development cost
- Defect Density: Number of defects per unit of code
Use the following criteria to prioritize technical debt items:
- Business Impact: Effect on revenue, customers, or strategic initiatives
- Risk Level: Probability and severity of potential issues
- Remediation Cost: Effort required to address the debt
- Future Cost of Delay: Increased cost if addressed later
- Dependencies: Relationships with other work items or debt

Sample questions for evaluating technical debt:
- How difficult is it to make changes to this component?
- How confident are you in the stability of this component?
- Are there adequate tests for this component?
- How well is this component documented?
- How current is the technology stack for this component?
- How well does this component adhere to our architectural principles?
- How well does this component scale with increased load?
- How maintainable is this component for developers unfamiliar with it?
- How many incidents/bugs have been attributed to this component?
- How difficult would it be to replace or significantly refactor this component?
| Dimension | 1 (Low) | 3 (Medium) | 5 (High) |
|---|---|---|---|
| Business Impact | Minimal effect on operations | Noticeable impact on efficiency | Significant business constraint |
| Risk | Low probability, minor consequences | Moderate probability, manageable consequences | High probability, severe consequences |
| Remediation Cost | Small, localized changes | Moderate refactoring required | Extensive reengineering needed |
| Future Cost | Minimal increase over time | Moderate growth rate | Exponential growth if delayed |
