Fix it twice or fix it two ways is a management term coined by Joel Spolsky, who coined the term for a process improvement method. It implies a quick, immediate solution for fixing an incident and a second, slower fix for preventing the same problem from occurring again by targeting the root cause.
The method suggests that every problem might be an indication of a deeper design fault, and is also an opportunity to improve beyond fixing the specific instance.
In human engineering, particularly in GUI design in the software industry, the second fix may be a usability improvement to reduce customer service inquiries on how to achieve a specific goal with a tool. With accident investigation, the second fix refers to safety improvements or extending the safety procedures, as in airline safety, while the first fix is the proceeding at the time of the accident. In management, the second fix can refer to methods of preserving knowledge in an effort to push for making only new mistakes. Fix it twice is therefore an attribute of CMMI level 5 management.
