TechDebt.org is the first collaborative & open benchmarking dashboard on Technical Debt and Software Quality. This is the fourth report based on TechDebt.org. If you have checked the site lately, you must have noticed that it has been totally remade. Not only does it use a much more beautiful interface but it also provides many additional metrics. We are going to take you through the various panels, metrics and charts proposed. Hopefully, this will help you understand and analyze technical debt, with more figures, more details, more knowledge.
