Sunil Bharti Mittal on Outsourcing Strategy

Sunil Bharti Mittal built Bharti Enterprises from a small bicycle-parts trading business into Bharti Airtel, one of India's largest telecom operators, and is most associated with the strategic decision to outsource the network and IT to Ericsson and IBM rather than build them in-house.

The outsourcing model — keeping brand, customer and distribution in-house while contracting out the network and IT — was a structural inversion of the integrated-telco model dominant globally, and is treated as the defining strategic choice that let Bharti scale faster than its capital would otherwise have allowed.

The acquisition of Zain's African operations in 2010 extended the model across the continent, making Bharti the largest African mobile operator by subscriber base and a test case for whether the Indian outsourcing playbook would transplant to lower-ARPU markets.

The decision to extend the outsourcing model into Africa rather than staff up locally is treated as the empirical test of whether the Indian telco playbook was portable; the subsequent unit economics broadly confirmed the model with market-specific modifications.
