Historical Review• First Quarter 2009, plants started
reporting data in Consolidated Data Entry (CDE) system• Monthly number of “Human Performance
Errors”• Quartile ratings calculated by INPO based on
monthly and quarterly data• Industry data found under “Additional INPO
Indicator Results” on Plant Information Center homepage

Challenges with reported data in 2009
• Some stations reporting “errors” not meeting significance criteria in INPO 08-004 and CDE Data Element Manual, INPO 04-004• Not being detected and corrected by HU leads
• Action needed by HU leads• Know who is updating CDE for your site• Ensure they are using correct site indicator for
input data• Validate correct data entered

Challenges with reported data in 2009
• Again – only report data meeting the significance criteria for a station event (site clock reset) as defined in 08-004
• Why not change indicator title to “event” instead of “error”• “Event” term already used by INPO for analysis of
industry submitted operation experience reports• Still being evaluated by analysis group at INPO

Human Performance Event Performance Indicators
• There is other “Human Performance Events” data in the Plant Information Center (PIC) • Not the same as the new 08-004 indicator
• Stations report number quarterly
• Determined by INPO Analysis Group review of submitted Operation Experience reports
• INPO Analysis Group tags Human Performance as applicable during analysis of submitted Operation Experience reports

What’s next?• 18 months of industry data will be available
end of second quarter 2010; then• Calculation will start using rolling 18 months
(aligned with 08-004)• Indicator will move into Plant Information Center
(PIC)• Targeted for implementation after 2010 second quarter
• Quartile values calculated using 18 month rolling data

What’s next?• Industry team worked hard to establish
station event criteria in 08-004, but based on roll-out experience it is time to revisit the criteria.

SITE HUMAN PERFORMANCE EVENT-FREE DAY RESET CRITERIA
Definition of a Site Human Performance Event-Free Day (EFD) Reset – When an event, as described in the table below, occurs as a result of either of the following:
• an initiating action (error) by an individual or group of individuals (Re) (event resulting from an active error)
• an initiating action (not an error) by an individual or group of
individuals during an activity conducted as planned (Md) (event resulting from a flawed defense or latent organizational weakness created within the last 18 months)
