Abstract: | Ambidexterity is an organization's context to achieve alignment and adaptability simultaneously within the organization learning processes. This paper examines the relationship between and significance of two key factors of organization learning (exploration and exploitation of knowledge) and two possible control factors (company size and sector) on the ambidexterity context, and their effects on the creation of customer capital. These relationships are examined through an empirical investigation of 269 Spanish SMEs from two different sectors (Optometry and Telecommunications), using structural equation modelling validated by factor analysis. The results indicate that the effects of exploration and exploitation of knowledge on customer capital are mediated through an ambidexterity context, which in this study is not affected by the size of SMEs but might be related to the sector in which they operate. |
