A Practical Guide to Writing a Software Technical Design Document

One of the key skills a senior software engineer should have is to write Technical Design Documents (TDD). However, not many companies actually teach their engineers how to write a good one. Many engineers have to learn by doing or observing how other engineers do it.

For many engineers, they can code perfectly but they don't really know where to start for TDD. Many of them question whether there is a need to write one. From my decades of engineering experiences, TDD is a must and even a tool to help engineers achieve engineering excellence and create good systems with grounded principles.

This tiny book will guide you through the writing process of a Technical Design Doc. It also comes with a real-life example of a Technical Design Document.


  • Document Structure from a Bird’s-eye view
  • Diving Deep on Each Section
  • Design Review Process
  • Other Applications
  • Final Note
  • Appendix A (Example)
