How much detail would you like?
Practical
Combines the decision for a pilot with questions about long-term operation.
Example scenario: A model depends on an undocumented data source; a change there makes its results unreliable.
Document data paths and dependencies; plan maintenance and revision from the beginning.
At a glance
- Core
- In addition to code, data dependencies, configurations and feedbacks can make subsequent changes more difficult. Rapid introduction can thus cause long-term follow-up costs.
- Use
- Combines the decision for a pilot with questions about long-term operation.
- Example
- Example scenario: A model depends on an undocumented data source; a change there makes its results unreliable.
- Limits
- Consider only model code; do not document dependencies; equate short-term success with permanently low operating costs.
