Start with a Purpose

Every data decision flows from why you are collecting data in the first place. Learn how a clear purpose shapes better data.

Collect Only What You Need

More data is not always better. Learn why limiting collection reduces risk, cost, and complexity.

Use Consistent Formats

Inconsistent formats are one of the most common sources of data errors. Learn how standardization prevents problems.

Maintain Data Quality

Data quality degrades over time without active maintenance. Learn how to identify and address common quality problems.

Document Everything

Undocumented data is data that cannot be trusted or reused. Learn what to document and how to keep documentation current.

Protect Sensitive Information

Personal and sensitive data requires specific protections. Learn the core principles of data protection and privacy.

Back Up Important Data

Data loss is preventable. Learn backup strategies that protect your organization from hardware failure, accidents, and ransomware.

Review and Improve Regularly
