Former Test off-spinner Ahmad said finding a good opening batting pair and raising players' fitness levels were also important.
"My first priority would be to pick specialists instead of all-rounders. A specialist has more chances to deliver and improve his game," Salahuddin told The News, a leading English-language daily.
His comments will alarm all-rounders such as Shahid Afridi, whose big-hitting style has not always been matched by recent performances, Abdul Razzaq and Yasir Arafat.
They could equally apply to batsman and occasional off-spinner Shoaib Malik, who is tipped to be named later Thursday as the new Pakistan captain after the nation's World Cup debacle.
"I am not against all-rounders but I do not like "makeshift" arrangements," Salahuddin, appointed by the Pakistan Cricket Board (PCB) on Wednesday, told Dawn, Pakistan's oldest English daily.
"A cricketer must and should be selected for his specialisation in one department and his additional qualities in other departments should be treated as secondary."
Salahuddin said he also wanted to solve a long-term problem for Pakistan by finally finding a decent duo at the top of the batting order.
"I always think there is a need to develop a trustworthy opening pair. A good batting line-up always has that quality," he told the News.
"Pakistan have always struggled in this front."
He also took an apparent swipe at earlier selection policies which saw Pakistan keep faith with injured opening bowlers Shoaib Akhtar and Mohammad Sami before ruling them out of the World Cup at the last minute.
"Fitness will be the key to my selection priorities.... There would be no compromise on the fitness of a player no matter how experienced or valuable he is otherwise," he added.
Salahuddin and his new selection committee colleagues Shafqat Rana and Saleem Jafer are due to hold a press conference later Thursday with PCB Chairman Nasim Ashraf.
