HTC has – again – reshuffled its executives, with the company stating that it is working to “ensure the continued strength of our company’s organisational structure”.

According to Bloomberg, Ben Ho, CMO, and Fred Liu, president of engineering and operations, have left the company. Ho has resigned while Liu retired.

In addition, the report said that Paul Golden, a former marketing head with Samsung who joined HTC earlier this year, had departed following the end of his initial contract.

Engadget reported that Ho’s departure, after a little over 18 months, had been expected, with the failure of a high-profile ad campaign to manifest itself through demonstrable results being the culprit.

While it had been said that Cher Wang, HTC’s chairwoman, was taking in Ho’s marketing responsibilities, this has been denied by the company.

Last year Wang took over some operational duties from Peter Chou, HTC’s CEO, in order to enable him to focus on product development.

HTC has suffered from several tough years, including a couple of loss-making quarters, at it has struggled to take on the marketing might of bigger rivals such as Apple, Samsung and Sony – despite the generally acknowledged strength of its products.

The company has unveiled some significant smartphones already this year, including its One (M8) device and mid-range 816.

And the company has seen numerous executive departures over the last couple of years. Recent departures include its design head, global operations head and chief product officer, as well as various regional leaders.
