Daniel Anderson was named as the club's General Manager of Football Operations on Friday: a move Seward says is the final piece in the puzzle.
"I'm very excited to welcome Daniel back to the Eels, he's a past coach with Grand Final experience and experience all around the world coaching, and in rugby league administration," Seward said.
"He's well respected within the game, and it's exciting to have him back."
Explaining Anderson's role, Seward says it will be an overarching role to manage the processes and development of the Eels players, from juniors through to the NRL.
"The General Manager of Football Operations is a new role, it's part of us turning our football department into a modern-day football structure," Seward said.
"It's based on research we've done both here in Australia and overseas, and we think it's the best chance to give us long term, sustainable success."
Seward says the relationship between Anderson and Head Coach Brad Arthur will be a crucial one.
"I think the GM of Football and the Head Coach relationship will be the most important one in our business," Seward said.
"The Head Coach will be given the opportunity to coach our team and coach really well to get success."
"The GM of Football Operations will look after the pathways, performance, the development of our players; the recruitment and retention, and make sure we have pathways for our players here to play at their very best."
A key part of Anderson's position will be to ensure talented juniors stay at the Parramatta Eels.
"It's about developing pathways for our junior league players, providing the right opportunity for NYC, NSW Cup and NRL players, and we expect it'll start delivering us some success," Seward said.
"I'm making no apologies - our football department over the last decade, especially the last few years hasn't been successful, so we're doing everything possible to get some success back at the Eels."
"It's about providing the right pathway and environment for our junior players to make sure they've got success and make sure they've got success here," Seward stresses.
"We want them playing at Parramatta Stadium, in Blue and Gold, for the Eels - not playing against us."
