In large enterprises and legal societies, procedural justice pays more attention to the traces of procedures on data (auditable evidence)，So the input and output data is the most important.
Addition， I agree with the following view:
```
Even the simplest procedural logic is hard for humans to verify,
but quite complex data structures are fairly easy to model and reason about.
...
Data is more tractable than program logic. It follows that where you see a choice
between complexity in data structures and complexity in code, choose the former.
More: in evolving a design, you should actively seek ways to shift complexity from code to data.

Show me your flow charts and conceal your (data) tables and I shall continue to be mystified, show me your (data) tables and I won’t usually need your flow charts; they’ll be obvious.
