Microsoft's head of phones, Jo Harlow, has also left the company
Tom Warren / The Verge :
Context & Ripple Effects
Jo Harlow's exit removes the executive lead on Microsoft's phones business just as the company's device strategy is in flux, and she is far from alone: Developer Division chief Somasegar walked out the door months later after 27 years, followed by Julie Larson-Green in 2017 and Cortana chief Javier Soltero in 2018.
Read against the full arc, this 2015 departure is an early entry in what the related coverage frames as a chronic retention problem — a pattern that culminated in Microsoft's recent wave of executive departures and its overhaul of annual rewards and performance programs, alongside long-tenured exits like Julia Liuson's resignation memo and Rajesh Jha's retirement from Experiences & Devices.
First-order effects
- Microsoft's phones organization is left without its named leader, forcing Satya Nadella's team to either backfill the head-of-phones role or formally fold the function into another division.
Second-order effects
- Each senior loss compounds the succession load elsewhere in the company — the same dynamic that later pushed Microsoft to promote four of Rajesh Jha's direct reports to EVP when he retired, rather than hire externally.
- Rivals and recruiters gain a recurring opening: a decade of departures by 25-plus-year veterans like Larson-Green and Liuson hands competitors access to institutional knowledge Microsoft spent decades building.
Third-order effects
- If the pattern holds, Microsoft's response — reworking rewards and performance programs to stem attrition — signals a structural shift where retaining long-tenured leadership becomes an explicit program rather than an assumed default, and succession planning moves from episodic backfill to standing organizational machinery.
The trend: Microsoft's most senior leaders keep exiting after multi-decade tenures, turning executive retention from an HR footnote into a board-level operational challenge the company now redesigns compensation programs to address.
