code in Gitlab, “SQL” or “How To” sheet in Excel, …)
• Repository of clean analysis where unnecessary
lines of code (“wandering”) are removed (“scratch” vs
“production” folder in Notebook, Gitlab deployment)
• Self-service ETL tool to repeat refresh of a critical
team table (e.g., Windows Scheduler, CRON on a
Linux machine, Tableau Data Prep, …)
• Ability to chain jobs
• Get alerts when a job fails

Control—Trust but Verify
Maximum Control
• All use-cases are lockdown
• Only a centralized IT team can have
access to the data and create report
• Least amount of risk
• Least amount of innovation
• Slow to react to change
• High certainty in outcome
Maximum Flexibility
• Any use-case is possible (historical
or new)
• Anybody can do anything on the
data
• Maximum amount of risk
• Maximum amount of innovation
• Fast reaction to change
• Low in outcome principle

but on successful training and authorization,
various access levels can be granted
• Control Certainty in Outcome (i.e., ask 5 people,
get 1 answer)—“gold badge” for enterprise
outcome, “bronze badge” for community outcome;
training and documentation
• Self-Service for day-to-day operations
• Browser-based tool (no extra tools)
• Enable Low-Code/No-Code

and business SME name in the footer)
