Stephen Mangongo has been named caretaker coach of the Zimbabwe side for their home series against Bangladesh this month.
Mangogo was assistant coach to Englishman Alan Butcher on the recent tour of the Caribbean and says he is now planning to make sweeping changes.
Meanwhile, Zimbabwe Cricket communications manager Lovemore Banda says the hunt for a permanent coach is ongoing.
Banda said: "Following interviews for the national coaching post, which fell vacant on the first of this month, the Zimbabwe Cricket board is still considering the report from the technical staff appraisal committee, and will make an announcement when it has completed that process.
"In the meantime, Stephen Mangongo, who was assistant to outgoing head coach Alan Butcher, will act as coach for the Bangladesh tour to Zimbabwe."
Change of tactics required
Mangogo is among the candidates for the permanent job and currently has 28 players with him in a training camp which began on Tuesday.
"I believe a change of tactics is required here and it's the route I intend to take during the training sessions," he said.
"I intend to find and weed out those players who are not doing their job.
"I have already presented my findings to the selectors and recommended a few new players I wish to take on board, so you can expect some changes during the Bangladesh visit."
Zimbabwe will play two Tests, three one-day internationals and two Twenty20 matches against the Bangladeshis, beginning with the first Test in Harare on 17 April.
