Hackett and Darren Currie have been assisting interim boss Wayne Burnett since he took the reigns from John Still, who swapped Victoria Road for non-league Luton almost a month ago following nine largely successful years at the helm, taking assistant Terry Harris with him.
The Daggers have won one, lost one and drawn three under Burnett and remain 16th in the League Two table, the same spot in which Still left the club.
Reflecting on the first month of Dagenham's post-Still era, Hackett, who has stepped up from academy coach, told Daggers Player: "I don't think we can grumble, really.
"We've had a real positive response from the whole group, first-team regulars, development players.
"We've had some very good results away from home. If I'm being honest I would have liked to have had a win at home, but unfortunately it's not to be. The Torquay game was a good opportunity, Chesterfield as well was another opportunity, but we didn't do that.
"But it's all a work in progress and I certainly think we're going in the right direction at the moment."
With Dagenham requiring just a handful or so more points to make sure of safety, Hackett's targets over the remaining seven games of the season are simple.
"To win as many games as possible and hopefully more players will get the chance to show what they can do," he said. "I think they're the only real aims, to get as many points as possible on the board and to get players playing."
