Likewise, exports and digital-related infrastructure are found to correlate positively with the expected digital technology adoption for customer relations business function. Similarly, study results from the transition probability matrix reveals that a significant persistency pattern is prevalent in all the three business functions of the firms, namely, supplier relations, customer relations and product development.
