Dav Whatmore and Julien Fountain have signed two-year contracts with the PCB as Pakistan coach and Pakistan fielding coach respectively.
Whatmore and Fountain had arrived in Lahore on March 2 but there had not been an official announcement regarding their appointment.
On March 4, Zaka Ashraf, the PCB chairman, and Intikhab Alam, the director of international cricket, formally announced that Whatmore and Fountain had been contracted by the board.
Whatmore, who has previously coached Sri Lanka and Bangladesh, has been linked with the Pakistan coaching job since December last year.
Whatmore said his goal was to bring some consistency to the team and do away with the poor performances.
The appointments come after Pakistan followed up their whitewash of England in the Test series in the UAE by losing 0-4 in the ODIs and 1-2 in the Twenty20 internationals.
Whatmore's first assignment is the Asia Cup, a one-day tournament also featuring India, Sri Lanka and Bangladesh.
