The Red Devils sacked Solskjaer following a poor run of results and announced their intention to appoint an interim boss until the end of the season, a move that has infuriated the United legend.
Ferdinand told his Vibe with FIVE YouTube channel: "All of a sudden, the game happens and we lose, and the club make a decision. It’s all reactive. Nothing is prepped. Even the management situation, surely you look at this before?
"You identify a certain candidate and know. It’s almost like, ‘Oh, this result has happened, we’re going to sack Ole, now we look for someone to come and take charge. We’ll put an interim before the interim, and then we’ll look for a manager.'
"It’s actually embarrassing. You’re just sitting there trying to protect the club, and you want to be positive, but I can’t."
Ferdinand feels that United should have used the recent international break to dismiss Solskjaer and hire a permanent candidate for the position.
The former England player said: "Surely there’s a candidate that should have been identified weeks ago because you could see what was coming?
"You see the club isn’t performing, you have a two-week international break. It’s the perfect time to start going round and identifying the next candidate.
"You can’t keep changing the conductor if you do nothing with the orchestra."
Ferdinand also questioned the decision-making at the club as he hit out at the "flagging" Premier League giants.
He said: "Man United have always been a team you associate with being best in class, elite in all aspects of the club – whether it’s the business angle, the commercial angle, also on the pitch.
"At the moment, it’s everything but that in all of those areas. That is the worrying thing for me. Every area looks like it’s just flagging.
"Yeah, the commercial area is doing well, but Man United are a global brand so you expect that. In terms of making decisions and being decisive, it’s everything but."
