Usefulness, social influence, and ease of use of object-oriented systems development: Beliefs of experienced OO developers


While many practitioners and academics attest to the purported advantages of object-oriented systems development (OOSD), others express concern about its complexity and immaturity. At issue is whether OOSD will become a dominant systems development approach as we approach the new millennium. This study examines a wide variety of beliefs and conditions about OOSD based on a survey of 94 experienced OO developers from across the U.S. These OOSD beliefs can be grouped into three categories (usefulness, social influence, and ease of use), based on Ajzen's (1) theory of planned behavior. The validity of beliefs and existence of conditions associated with OOSD are explored by examining the mean, variability, and statistical significance of ratings provided by developers. Findings suggest that the majority of beliefs about the usefulness, social influence, and personal ease of use of OOSD are valid. However, conditions related to the situational ease of use of OOSD are generally inadequate.
