Personnel Performance Appraisal (PPA) involves systematically evaluating the employee’s performance in the workplace. The purpose of PPA is to identify an individual’s strengths and weaknesses, which impact the overall performance of the organization. The construction sector is commonly perceived as an unorganized industry. This paper compares the PPA systems of a Construction Organization (CO) and information technology (service-based) organization and explores potential solutions for continuous improvement. The study utilizes case studies and incorporates semi-structured interviews with Information Technology (IT) professionals and construction professionals. Documented reviews and semi-structured interviews are meticulously documented, recorded, and transcribed. The gathered data are recapitulated and depicted based on recurring topics. Given that both construction and IT organizations operate within a project-based culture, the disparities, and similarities between their respective PPA practices are identified. It becomes apparent that employees in the IT organization possess a clear understanding of the PPA process and its relevance, whereas this cognizance appears to be deficient within the CO. Notwithstanding the implementation of PPA in the CO, this comparative analysis indicates that there is potential for enhancement.
