Yahoo is considering a reorganisation to centralise its mail, search and homepage divisions into a global product organisation, the Wall Street Journal reports.

The newspaper reported that president Sue Decker was behind the move, which was an attempt to improve co-ordination between product and global sales groups.

The move comes as Yahoo, which has ended talks for a tie-up with Microsoft in favour of a search deal with Google, tries to convince investors it will substantially improve its business.

It also comes at a time when senior executives are leaving the company.

Vish Makhijani, general manager of Yahoo’s web search business, and Brad Garlinghouse, who oversaw services including email and instant messaging, are leaving, according to technology and investment blog TechCrunch.

It said Qi Lu, the top engineer for Yahoo’s Panama search marketing platform, was also leaving the company.

And Yahoo said at the start of the week that Jeff Weiner, recently executive vice-president of the network division, had left to work at a venture capital firm.
