Reflections on Project Refactoring

Why Refactor

Before starting a refactoring project, it is critical to plan the migration strategy between the old and new systems in advance.

Refactoring is not just about code cleanliness—it is about solving real project problems.

Key principles:

• Plan the switchover strategy early
• Treat data refactoring as a top priority
• Refactoring must have measurable goals
  • e.g., 5% performance improvement
  • 30% reduction in development effort
• Avoid chasing trendy technologies
  • Prefer mature and simple solutions
  • Mature solutions are easier to troubleshoot and better documented

Team Management During Refactoring

Refactoring is not only a technical challenge—it is also a team coordination challenge.

Key Practices

• Continuous tracking and review

  • Perform regular code reviews
  • Adjust direction early when problems arise
  • Scrum-style iteration works well: deliver → test → feedback → adjust

• Establish coding standards

  • Provide reference templates and examples
  • Enforce standards using tools such as Checkstyle
  • Consistency matters in multi-developer teams

• Make incremental changes

  • Avoid large, risky rewrites
  • Refactor in small, controlled steps
  • Add or update unit tests alongside changes

• Invest in team growth

  • Team members have varying skill levels
  • Provide guidance and mentoring where needed

Project Management Awareness

Strong technical skills alone are not enough for successful refactoring. Project management knowledge is equally important.

Recommended learning:

• Scrum and agile practices
• Iterative delivery models

Final Thoughts

Refactoring succeeds when:

• Technical goals are clear
• Business value is measurable
• Teams communicate effectively
• Changes are incremental and controlled

A well-executed refactoring effort improves not only system quality, but also team maturity and long-term development efficiency.
