Jim Duffy received assurances from owner Vladimir Romanov about Hearts head coach Graham Rix's future before accepting a director of football role.
Jim Duffy has been promoted to director of football at Hearts
"I met Vladimir on Saturday night and he asked me if I wanted the job for the rest of the season," said Duffy.
"I asked if Graham would remain until the end of the season as I was concerned about continuity at the club.
"He insisted that unless something dramatic happened then he would be. The players know Graham is in charge."
The 46-year-old Duffy has been promoted by the Lithuanian after first arriving at Tynecastle before the end of last month to help out with coaching duties.
"It would have been a difficult decision without those assurances because of the uncertainty," he said.
"But, when I was assured about Graham, I accepted straightaway."
Rix's future had been under a cloud after reports emerged he told the players before the match against Dundee United at Tannadice last week that Romanov, the club's majority shareholder, was picking the side.
A players' delegation, led by captain Steven Pressley, held talks with Romanov that ended amicably, but Duffy admits he did not quiz Romanov on the matter.
"I didn't need to ask if Graham was picking the team because I know he is," he stressed.
"Graham can now concentrate and enjoy what he was brought to the club to do, which is working with players, and he doesn't have to be rushing away to meetings or things like that.
"The players will be delighted that the problems have been put aside and they can concentrate on what is still an opportunity to have a great season."
The former Hibernian and Dundee boss has previously worked with Rix at Chelsea and Portsmouth.
Despite his promotion, Duffy insists Rix does not have to answer to him now.
"I'm not his boss, I'm there to help him," he said.
"I will be looking at all the aspects of football like recruitment, medical developments and contracts - and reporting back to Mr Romanov."
