Knowledge sharing, a key sustainable practice is on risk: An insight from Modern Code Review

Knowledge is the foremost asset to succeed in the area of green sustainable software engineering. Effective knowledge sharing is a crucial objective of companies. However, individuals are not motivated to share knowledge. This study explores knowledge sharing in the context of Modern Code Review (MCR) where engineers assess source code composed by other developers to improve the product quality through knowledge exchange among developers (Author and reviewer). The procedure is profoundly subject to individual associations among developers regarding contribute to the outcomes of MCR such as identifying alternative solutions, code improvement, and knowledge sharing. Knowledge sharing is supposed as an important outcome of MCR; however, developers involved in MCR activities are confronted with a lack of knowledge sharing challenge due to a dearth of knowledge sharing motivation. There are different individual factors that might encourage or hinder developers to engage in knowledge sharing. Studies have been performed dependent on information investigation gathered from surveys, interviews and review tools concerning elements affecting MCR, still the literature lacks research regarding factors impacting knowledge sharing aspect in MCR. Hence, this examination performs a Systematic Literature Review (SLR) that distinguish individual factors impacting knowledge sharing in MCR. The examination discoveries 34 individual factors such as biasness, cognitive load, time pressure, expertise, etc. The factors are grouped into 7 broad categories utilizing grounded theory. Study discoveries have suggestions for programming specialists involved in MCR activities and researchers interested to perform research in this area to broaden the examination and perform MCR exercises adequately by considering and beating the negative effect of recognized variables.
