PROBLEM STATEMENT oSMEs make a significant contribution to economic development via the creation of employment, technological advancement, reduction of poverty, innovation, and wealth distribution (Agyei, 2018; Ye & Kulathunga, 2019).oThus, this particular study investigated the effect of significant SMEs' performance, including operation efficiency, Availability of business information, access to infrastructure, and Business environment on SMEs' performance to address the gap found in the entrepreneurial literature and practice of Saudi SMEs.oIt was noted that most Saudi SMEs randomly prepare economic feasibility studies to obtain loans and financial support, which is another major issue that contributed to the failure of many projects (Tripathii, 2019).oParticularly the role of operation efficiency, Availability of business information, access to infrastructure, and Business environment in predicting SMEs' performance is deficient in prior studies (Karadag, 2017; Ying et al., 2019).o SMEs' performance remains crucial because it assists the ongoing transformation of the KSA economy towards diversification (Ali, Hilman, & Gorondutse, 2020).SMEs that work well are essential to stability and continued economic growth.
