SUMMARY:Integrating Task and System Perspectives: The Performance Analysis
  Technique for Analyzing Procedural Work
DESCRIPTION:Atif Ashraf and Abigail Jei (Texas A&M University); Camille Pe
 res (U.S. Nuclear Regulatory Commission); and Farzan Sasangohar (Texas A&M
  University, Houston Methodist Hospital)\n\nHigh-risk industries utilize S
 tandard Operating Procedures (SOPs) to maintain safe operations and regula
 tory compliance (CCPS, 2010). These procedures provide detailed, step-by-s
 tep instructions for workers performing both routine and non-routine tasks
 , specifying the work scope, hazards, equipment requirements, and document
 ation needs (UK Health and Safety Executive, 2020). However, a persistent 
 gap exists between how work is prescribed in procedures (Work-As-Imagined 
 or WAI) and how it is performed (Work-As-Done or WAD) (Hollnagel, 2012). T
 his discrepancy becomes particularly significant in dynamic environments w
 here workers must adapt to changing conditions, such as competing prioriti
 es or varying worker competencies (Dekker, 2003; Hale & Borys, 2013). Whil
 e research has identified this gap, few studies have examined these differ
 ences during normal operations, particularly in high-risk industries such 
 as oil and gas (Sasangohar et al., 2018). This study introduces the Perfor
 mance Analysis Technique (PAT), an analytical approach that integrates Hie
 rarchical Task Analysis (HTA) and Abstraction Hierarchy (AH) to systematic
 ally examine the differences between WAI and WAD.\n\n
