Andy Murray will continue to work with coach Amelie Mauresmo in 2016, but Jonas Bjorkman will no longer be part of the Scot's team.
Mauresmo gave birth to her first child in August, but is planning to work 22 to 24 weeks with Murray, 28, next year.
The world number two hopes to have a new assistant coach in place for the first Masters event of the year in Indian Wells in March.
"For me there were a lot of positives last year," said Murray.
"But the last step is the most important thing and we need to work hard together to get back to winning the Slams. I've just got to find the way to get the wins against the top players in the biggest matches again."
