However, there is scarcity of research that have considered the relationship between market orientation, service marketing mix and microfinance performance. most studies conducted on the direct relationship revealed inconsistencies. Due to the inconsistencies in the literature on this relationship, a moderating variable of environmental turbulence was proposed.
