The changes do not include replacing CEO Kevin Rollins.
At a press conference on 12 September, Dell admitted his company's performance in recent years has been less than stellar.
"We weren't living up to expectations, so we're changing things," he said.
"Any speculation is politically useless, but feel free to speculate," he said. And added, "if you want to blame someone, you can blame me, too."
The company has been battered in recent months with disappointing earnings and the recall of 4.1 million potentially flammable notebook batteries. The company has also been hammered by critics who say it failed to keep pace with a number of technology advancements, including blade servers and the use of AMD processors.

Dell has also been plagued by a Securities and Exchange Commission investigation into the filing of possibly inaccurate reports, which forced the company to delay filing its second-quarter financial results.
Now the 20 year-old company built on an innovative (at the time) pricing, manufacturing and sales strategy is trying to regain ground.
But some observers said Tuesday's message fell flat.
"They're launching initiatives to address these issues they're having, but the question not being asked is why do they keep missing their revenue," said Roger Cox, an analyst at Gartner. "What have they done to change that? Right now it's all words. It'll have to come out in the execution."
The "new" Dell model, dubbed Dell 2.0 (as in Web 2.0), builds on better customer relationships through services.
Rollins admitted that Dell fell short when it came to customer expectations. But he pointed to Dell's $150 million investment "just to improve customer relationships" adding that customer experience is the company's No. 1 priority.
"It's where we're investing now and in the long term," he said. "We're committed to doing everything at Dell better in order to enhance the customer experience. We believe our customers expect and are willing to pay for better service."
Dell is also opening manufacturing facilities in emerging markets, such as Brazil, India and central Europe, in order to get closer to the customer and reduce cycle time, Rollins said.
Although still committed to its direct sales model, Dell said online sales will increasingly be part of its sales strategy.
At the end of the day, some observers expressed confidence in Dell's ability to revitalise its business but insist the company didn't falter as much as some critics claim.
"I don't think they were in trouble," said Joseph Zhou, analyst, Ideas International Inc., Rye Brook, N.Y. "They sustained market share. They warded off the competition. But they didn't make as much. They could do better. There are ways to increase revenue and they're not necessarily doing that. They should focus on other areas besides hardware."
City University of New York CIO Brian Cohen said he's never been swayed by industry rumblings about Dell.
"They have, over the years, been an amazing partner," Cohen said. "They've enabled us to move forward in ways that we wouldn't have been able to afford. They've never given us any reason to look elsewhere. We continue to have confidence in Dell."
