The normalization of Work from Home (WFH), Work from Office (WFO), and hybrid work has intensified interest in employee productivity, yet prior research often examines ergonomic, psychological, organizational, and environmental determinants separately. This fragmentation limits integrated understanding of how enabling and constraining conditions differ across work arrangements. This study addresses that gap through a structured narrative review of 50 scholarly sources published between 2020 and 2025 using an adapted Performance Shaping Factors (PSF) perspective. The review integrates physical, cognitive, organizational, environmental, and individual factors into a 31-factor codebook and combines thematic synthesis, frequency and Pareto mapping, and separate WFH-WFO matrices for enabling and constraining factors. The synthesis indicates that organizational and cognitive conditions are especially prominent in the literature, while physical, environmental, and individual conditions remain consequential. WFH more often supports autonomy, concentration, work-life balance, and remote-work support, but is also associated with greater exposure to technostress, interruptions, social isolation, household demands, and musculoskeletal discomfort. WFO more consistently provides communication, supervision, collaboration, training, and standardized ergonomic support. Frequency is interpreted as prominence in the reviewed literature rather than as effect size. The study contributes an integrated PSF-based framework for comparing work arrangements and offers a practical basis for designing hybrid policies that match work location to task, employee, and organizational conditions.
