errors keep creeping into existing system
in the high level, the goal of good quality data in system is less error, consistency, high coverage, high precision and fresh.
a system need tools to fix the data error, update the data to be fresh, precise and high coverage
the change needs to be incremental and continuous
before fixing the issues, it’s required to have tools detect issues
for human, we have 5 senses and feelings to detect external and internal issues
human body have immune system to fix issues automatically
spiritually, it’s much harder. we are not aware our knowledge is outdating. we are not aware our worldview, value system is flawed. we are not aware our understanding of our spouse, our children is limited. We failed to detect the issues and not willing change ourselves, as changes are painful.
a system is a living creature. keep changing, fixing and learning is the only way to survive and prosper.
