A Method of Quality Control for Systems that Quality Control Data
February 28, 2005NOAA / NOS / CO-OPS
System Quality Control
February 28, 2005NOAA / NOS / CO-OPS
A Classic Example
February 28, 2005NOAA / NOS / CO-OPS
National Current Observation Program
Provide Data for:• Navigation• Search and Rescue/HAZMAT• Coastal & Estuarine Circulation
Tidal Current Tables
Tidal Current Predictions from:– Area Surveys– Real Time in Shipping Channels

Why?• Increasing data flow
– Yearly increase in the number of data collection sites
– Increasing temporal resolution
– Increasing spatial resolution
• Collaboration
– Distributed Data Sets
– Various Numerical Units
– Various File Formats
• Antiquated Computer Software

Capability Maturity Model (CMM)
• CMM Level 3 – The development process follows well defined rules and methods
• Tracks time and progress• Method for attaining a quality of the final product• Robust Project Planning
