Albion have taken just one point from their opening three league games, failing to score in any of them, but Steve Clarke bolstered his squad with four new players on the last day of the summer window.
France midfielder Morgan Amalfitano joined on loan for the season from Marseille, and goalkeeper Lee Camp signed a rolling monthly contract to cover the loss of Ben Foster to injury, before forwards Stephane Sessegnon and Victor Anichebe were captured late in the day from Sunderland and Everton respectively.
Moore, who played for Albion between 2001 and 2006, is confident the new arrivals will help steer his former club well clear of the position they currently find themselves in.
"I think it's great business," Moore told Sky Sports News Radio. "The club wants to keep moving forward after last season and I think the players that have come in will enhance the squad.
"The last couple of results have shown that they need more depth, and they've brought in some real good quality.
"It's a great squad of players anyway. I had the joy of watching them last season and they're a great bunch. Nicolas (Anelka) coming in, Scott (Sinclair) coming in and Sessegnon coming in will add the quality and flair that's needed.
"I think they'll gel together, I think they'll bring great cohesion, and looking forward I see the team progressing and moving back up the league this season."
He added: "I really see them as quality signings. With West Brom it's never a knee-jerk reaction, it's always structured and planned. The way the club is run, those players would have been planned to come in over the summer.
"Hopefully they've got the men they wanted and now they can progress."
