Here’s today’s Silicon Valley roundelay:

Rob Macdonald (pictured here), head of traditional media and publisher partnerships at Google (GOOG), just joined online publishing and document-sharing start-up Scribd as SVP of business development.

He will be based in New York, where Scribd is opening an office too.

Over at AOL (AOL), former Yahoo (YHOO) exec Brad Garlinghouse has snagged longtime Apple veteran Alan Eyzaguirre (pictured here) as the new VP of AOL Mail.

Eyzaguirre, who was most recently director of software product marketing in Europe at Apple, will be based in Mountain View, Calif.

But Google is not without seat at this job switcheroo–it has hired Venkat Panchapakesan (pictured here), a high-ranking former Yahoo tech exec and a longtime company veteran who left the Internet giant last year to be an entrepreneur-in-residence at Greylock Partners.

At Yahoo, Panchapakesan was last EVP of the Audience Technology Group and at Google will be VP of Enterprise Engineering, according to his new LinkedIn status.

Yes, more layoffs are indeed coming to Yahoo, sources confirmed to BoomTown, but perhaps even more than have been reported.

But that’s not all, as even more top-level managers are either leaving or being moved around the ever-changing organizational structure at Yahoo (YHOO).

That includes a longtime top sales operations exec, Dan Foehner, who is about to start at Facebook next week, as well as others contemplating leaving, on their way out or are being reshuffled.

In other words, business as usual at the tumultuous company, whose nickname should be “Reorg.”

First, the layoffs, which the New York Times was first to report yesterday would be announced Tuesday (side note to Damon–this is how you link to scoops) during Yahoo’s first-quarter earnings call and could impact several hundred employees.

The quarterly results are expected to be weak by most analysts, which is why more layoffs–which had been mentioned by the company as a possibility–are an obvious move.

But several internal sources said Yahoo staff is bracing for employee departures that might to be even higher, as many as 500 or more.

That could mean a complete lopping off or sale of various business units that Yahoo CEO Carol Bartz has been evaluating since she arrived in January.

Why? Well, several employees said they were told the new round of cuts will not actually take place until June and that Yahoo HR is now preparing to follow the rules required by the Worker Adjustment and Retraining Notification Act.

Under the complex federal guidelines, Yahoo must provide a written WARN notice to affected employees “at least 60 calendar days in advance of covered plant closings and mass layoffs.” WARN notices are triggered for a variety of reasons, although a smaller number of layoffs across many units typically does not require it.

A WARN notice is required, for example, when an employer shuts down a facility or operating unit within a single site of employment and lays off at least 50 full-time workers, as well as when an employer lays off 500 or more full-time workers at a single site of employment.

In its last two layoffs, Yahoo issued WARN notices and slashed about 2,500 jobs in total last year, leaving it with about 13,600 employees world-wide at the end of 2008.

But some of Yahoo managers are still leaving on their own.

Many top engineers, for example, have taken jobs of late at Microsoft (MSFT) after the software giant installed a Yahoo tech star, Qi Lu, as its top online exec.

And, BoomTown reported earlier, there have also been numerous departures of key staff recently, including: PR head Jill Nash, Zimbra founder Satish Dharmaraj and soon, high-ranking techie Venkat Panchapakesan.

And more still, it seems.

Yahoo’s VP of Sales Operations Foehner, for example, is headed out after a long stint at the company and is going to Facebook, said several sources inside and outside the company.

On Foehner’s Twitter page, he tweets about a new unnamed job, as well as an athletic endeavor (Foehner is a dedicated triathlete): “back in pleasanton. starting bike adventure on thurs. start new gig on monday. 9 weeks til CdA!”

There is also a lot more movement inside Yahoo, as the reorganization done by Bartz in February shakes out.

Typical of this is Mike Walrath, the high-profile former CEO of Right Media, an online ad exchange snapped up by Yahoo for $720 million in 2007, who is now an advertising-focused SVP at Yahoo.

Now Walrath is moving out from under the purview of Yahoo North America EVP Hilary Schneider and will report to Ari Balogh, EVP of Products and CTO, as all search products seem to be rolling up through his organization. (Both Balogh and Schneider are pictured here.)

While there are other key execs at Yahoo–see this drastically downsized Yahoo management page, which used to be a lot longer–Balogh and Schneider have roughly split the company into two parts, product and engineering for Balogh and the bulk of the content and advertising businesses under Schneider.

Bartz is at the top, of course, and moving parts is not a complete surprise, said one exec, as she gets more control of the company.

“The last reorg was a blunt instrument, so now she is starting to surgically move people around or even out, after seeing what staff can and can’t do and what fat there still is,” said one exec close to the situation.

That’s no small comfort to Yahoo’s reorg-and-layoff-weary staff, especially at its Sunnyvale, Calif., HQ in the heart of Silicon Valley.

When Bartz announced her big reorganization in late February, she declared a moratorium to the endless reorganizations that had plagued the company’s troops for far too many years.

Wrote Bartz in an email to Yahoo employees about her new management lineup:

“I know you guys have reorg fatigue. Hang in there–our intention is to leave this structure in place for two to four years. We’ll continue to make adjustments as needed, but we expect this core structure to stay put.”

Perhaps the core is still solid, but a lot is still quite undefined at Yahoo, as it seeks to right its shaky fortunes.

Here’s an interesting irony–Yahoo CEO Carol Bartz will have her 99th day in office on the very one that the Internet giant will announce its first-quarter earnings: April 21, 2009 at 2 p.m. PST.

Technically, it will mean that she has been running Yahoo (YHOO) for 100 days, a time when most administrations get their first evaluation.

Thus, if it’s good enough for President Obama, it’s good enough for Bartz!

While most expect the results for the quarter to be weak, due to the econalypse, the overall verdict from BoomTown’s needling of Yahoos to give me info on their new leader recently: Love, love, love Bartz’s innate decisiveness, and wanting more of the same.

“She has an opinion and she is not afraid to use it,” joked one high-ranking Yahoo. “That is a big deal for a lot of people here who have wanted a CEO who is very forceful.”

And the only substantive negative: Some remain worried about her lack of Internet savvy, although most of those admit she has been a quick learner as the 100-day mark comes to a close.

In Yahoo’s case, 100 days has a special meaning–when he got his job in late 2007, former Yahoo CEO and co-founder Jerry Yang declared that he was going to give the troubled company a 100-day evaluation with “no sacred cows.”

The Yang-farmed bovines, as it turned out, just got fatter.

Under Bartz, more have been under the knife, as the hard-charging exec has started to really put her imprint on the company.

She has certainly talked tough since the meet-the-press conference on her very first day on Jan. 13.

Some memorable Bartz quotes were about Yahoo’s immediate needs, in her estimation: “some friggin’ breathing room” and “frankly, [the company] could use a little management.”

That kind of tough-lady, Annie-Get-Your-Gun quote-making has been Bartz’s signature, whether it be in folksy Friday memos she has sent out to staff or at the fourth-quarter earnings call in late January, only weeks into her tenure, when she declared:

“This is not a company that needs to be pulled apart and left for the chickens.”

Well, except for the management structure, which Bartz pulled right apart and reshuffled six weeks in.

Cleaning up and simplifying the complex reporting structure in an all-roads-lead-to-Carol set-up and tossing out the CFO were main points of the reorganization. Many at Yahoo expect there to be even more cuts in staff sooner than later, many sources said.

And there have also been departures of key staff, including: PR head Jill Nash, Zimbra founder Satish Dharmaraj and soon, high-ranking techie Venkat Panchapakesan.

Yang too, although he remains on the board, has not been present as much at the company.

Curiously, though, except for the new CMO, Elisa Steele–whose office is powerfully located right next to Bartz, as many Yahoos noted to me–there have been no further appointments for open positions for CFO, a new Customer Advocacy top exec and a new international head. Presumably, they are on the way.

Not that Bartz has not been busy–visiting Yahoo staff and clients all over–as well as finally finding time for a face-to-face meeting with Microsoft CEO Steve Ballmer in Silicon Valley recently.

Before the recent meetings, in a classic negotiating tactic, Bartz (pictured here) has projected a disinterested, poker-faced attitude about the situation, even telling Yahoo staff in one meeting “that she plans to spend a lot of time investigating whether to sell Yahoo’s search business, but that her ‘gut’ was not to do that.”

Well, a sale of Yahoo’s search business might not happen, Bartz was only buying a little time in being so confident and projecting the affect that Yahoo had some leverage and a choice.

But that is exactly what she does not really have, given that Yahoo faces the prospect of spiraling costs to maintain a search share, even as it has a good chance of declining.

So, last week, the news–first reported here Friday–that Bartz was involved in preliminary talks with Microsoft (MSFT) about an extensive commercial advertising and search partnership–should have come as almost no surprise.

A re-engagement between the companies, after a bruising takeover battle that ended in tears all around, has been long hoped for by investors and other observers, given that both have struggled against the search behemoth that is Google (GOOG).

(Or, in a nickname that BoomTown is trying unsuccessfully to popularize: Googzilla.)

The talks–which are not about the software giant making another acquisition offer for Yahoo–are ongoing and might not lead anywhere, but it is in both sides’ interest to avoid that outcome.

“Yahoo has to do some kind of deal or Bartz will be facing a decline even she cannot manage,” said one person close to the situation. “And Microsoft, if it wants to compete in search, needs Yahoo’s share along with its own.”

Among the surprisingly innovative ideas being bandied about: Yahoo might take over all of Microsoft’s display and premium advertising business to sell along with its own, while Microsoft would run the search advertising business for the pair.

And, while the discussions could degenerate into chest-pounding and pointless jockeying, one assumes that Bartz gets the idea that Yahoo needs a lot of help–including from some rapprochement with Microsoft, from making its staff even leaner, from streamlining its product focus and from striking other significant partnerships.

Many inside and outside Yahoo certainly hope that spirit–and not the one from this video below of a fabulous scene of Betty Hutton and Howard Keel in the musical classic, “Annie Get Your Gun,” singing “Anything You Can Do”–prevails with Microsoft in the next 100 days.

At least he’s not going to Microsoft (MSFT)!

But nonetheless, sources said another major Yahoo tech exec and a longtime company veteran, Venkat Panchapakesan (pictured here), EVP of the Audience Technology Group, is readying his departure from the company.

This time, it’s to return to India, where he has long told colleagues he wanted to return.

Sources said Panchapakesan will not be leaving until the end of the summer, but “his departure is well along the road.”

At Yahoo (YHOO), Panchapakesan has most recently been responsible for the company’s overall product technology and platform strategy, such as its open efforts.

He’s an old-timer at Yahoo, having arrived in 1998, and has been involved in the development and execution of technologies for lots of Yahoo products, such as Mail, Flickr, Answers, Groups, Messenger and its content properties.

But recent reorganization of the tech unit, along with Panchapakesan’s interest in working in India, hurried along his leaving.

According to his profile on LinkedIn, Panchapakesan moved to Bangalore, India, to become the CEO of the Yahoo India R&D in 2003, returning in 2006.

Previous to Yahoo, he worked at Hewlett-Packard (HPQ).

“It’s being changed every minute,” joked one Yahoo source about the reorg now in process at Yahoo, which is being shepherded by new CEO Carol Bartz.

Actually, it’s kind of true, as execs at the troubled Web company are being moved around the board like chess pieces, while other players are added.

According to numerous sources, mostly in Yahoo’s Sunnyvale, Calif. HQ, things are still in flux and not completely settled as yet.

But one thing is clear: Layers are being collapsed quickly, as fewer people are in charge of more, with all roads leading to Bartz.

Here’s the current lay of the land, in what is fast becoming Carol Country at Yahoo (YHOO):

Ari, Ari, Ari!

As BoomTown reported earlier this week, it looks like CTO Ari Balogh will be the biggest winner in the management restructuring, getting to ride herd over the entire product organization, both development and technology.

Most interesting is that Audience Product head and longtime Yahoo veteran Ash Patel is still staying–at this point at least–and report to Balogh (Patel had previously reported directly to outgoing President Sue Decker).

Many at Yahoo think Patel will eventually leave, even if he is not out in the current set-up.

But, if he stays, Patel will apparently focus more on product architecture, if he does remain, which is kind of the purview of Venkat Panchapakesan, EVP of the Audience Technology Group, who already reports to Balogh.

Superman exec Ari will surely sort it all out!

In this scenario, Front Doors head Tapan Bhat could get more product development responsibility, especially since media product development is being moved centrally under Patel.

Hilary Gets More Stuff

As someone perceived internally as a favorite of Decker, U.S. head Hilary Schneider seems to be scoring anyway.

She’ll run a new U.S. division, with media head Jeff Dossett under her, as well as advertising sales head Joanne Bradford.

Some Yahoos, though, think Bradford could report directly to Bartz, given her purview is the most important part of Yahoo’s business.

Schneider will also apparently get a much diminished Connected Life unit, which focuses on mobile and other devices, after the departure of its longtime head Marco Boerries.

I posted news of his leaving earlier today, which now means that part of Yahoo will not stand on its own as a separate fiefdom.

Who Is Joel Jones?

Indeed. Yahoo’s current VP of corporate strategy and former McKinsey consultant, Joel Jones (pictured here), is one of the nominees to be tapped to be Bartz’s chief of staff.

In the new, more centralized organization that Bartz is obviously creating, that will be much more than a bag-carrying role, to be sure.

“Joel is as sharp as they come,” said one former Yahoo. Sharp enough to help Bartz negotiate with Microsoft (MSFT) CEO Steve Ballmer?

No news on a possibly COO for Bartz, but she is getting a chief marketing officer to head up the brand and PR functions. Many are suggesting an exec like Pepsi-Cola North America interactive marketing exec John Vail, as I have previously reported, although Yahoo brand exec Allen Olivo is the internal candidate.

Also apparently staying for now is another Decker favorite, CFO Blake Jorgensen.

More to come!

On Friday, BoomTown first reported that new Yahoo CEO Carol Bartz is likely to be announcing a sweeping new management structure soon, which can only mean the possibility that some existing top execs are likely to be broomed out, even as some new ones are ushered in.

“This is going to be a full-scale peanut butter recall,” joked one exec, referring to the infamous “Peanut Butter Manifesto,” which was sent around the company several years ago by former exec Brad Garlinghouse. It laid bare the problems at Yahoo (YHOO), most especially a decided lack of decision-making and lugubrious levels of managers.

But the reorganization of Yahoo’s top-heavy management structures–I once dubbed it the “attack of the Yahoo vice presidents”–will be a bit sticky, given all the (slow-)moving parts at Yahoo (YHOO).

Nonetheless, Bartz signaled a “big week” ahead in one internal memo I obtained, which was sent out Friday.

So what’s to come?

Here’s a rough primer, based on talking to numerous sources inside and outside of Yahoo:

The Basics:

In order to start to revive Yahoo, Bartz is likely to impose a more top-down management style on the hopelessly confusing “matrix” organization now in place at the company.

She has spent the last six weeks touring Yahoo, getting to see a lot of presentations on its many, many products and conducting a whirlwind of meetings with execs.

Broadly, most expect Bartz to severely roll back a variety of previous reorganizations done by former CEO Jerry Yang and outgoing President Sue Decker, in order to impose more centralized control over the place and focus it more narrowly.

Presumably, lattes–paid for by Yang and co-founder David Filo–will remain free.

Out With the Old:

There’s no question that Yahoo is going to see the departure of several top execs, along with the elevation of others.

Among those who are more likely to be definitely in, though, is CTO Ari Balogh (pictured here), a relatively recent hire who has been a popular exec within Yahoo.

The Wall Street Journal first noted the possible rise of Balogh in a follow-up piece to this column’s story on the overall reorg over the weekend, noting that he would become head of product.

Presumably, Balogh will be one of the point men on what to do about search, in the should-I-stay-or-should-I-sell-now debate that never seems to end at Yahoo.

One interesting idea floating around Yahoo is that he becomes head of all its products, as well as continuing to run its tech arm.

That’s a good idea, since Yahoo has desperately needed an empowered leader under Bartz, who focuses like a laser beam on products.

“It all starts with that,” said one former exec. “One single person has to be the champion of what Yahoo makes.”

But what does that mean for Ash Patel, EVP of Yahoo’s Audience Product Division? Well, the longtime Yahoo veteran could now report to Balogh (he had previously reported to Decker directly) or, presumably, leave.

Patel’s fate, of course, impacts that of many others, such as Front Doors head Tapan Bhat, who is in charge of a major homepage redesign that Bartz just delayed the launch of to make it better.

Venkat Panchapakesan, EVP of the Audience Technology Group, seems safer, given that he reports to Balogh already and is responsible for the company’s overall product technology and platform strategy, such as its open efforts.

Also safer than not is General Counsel Michael Callahan, as well as U.S. EVP Hilary Schneider.

But Schneider’s purview might change a bit if U.S. advertising sales head Joanne Bradford–who now reports to her–is elevated to a higher position or if sales is taken out from under Schneider.

It’s not a stretch to imagine Bartz wanting more control of the part of Yahoo that brings in the bucks.

The fate of Connected Life Division EVP Marco Boerries is dicier–think Yahoo mobile and other devices–as it is for CFO Blake Jorgensen and David Windley, who heads human resources.

Both Jorgensen and Windley were favored by Decker, which does not necessarily make them goners. But both are in jobs on which Bartz will have to rely much more, so she might want her own choices in place.

Boerries (pictured here), a talented but more freewheeling exec under Yang, is another question all together. Already wealthy from selling several companies, the entrepreneurial exec is most often mentioned by sources as someone unlikely to stick around, especially if Bartz tries to rein him in more. (In addition, Boerries has family issues requiring that he spend a lot of time in his native Germany.)

As to the many Yahoo SVPs and VPs? Let’s just say it is likely there will be many fewer of them, as Bartz cuts, consolidates, simplifies and centralizes divisions more.

In With the New:

One hire that is definitely coming is a new chief of marketing to take over Yahoo’s brand, as well as its PR function. Yahoo has not had that kind of powerful exec in a long time, and it is more likely Bartz will go for an outside star here.

One outside name skittering around Yahoo for the role is John Vail (pictured here), director of interactive marketing for Pepsi-Cola North America, who knows Yahoo well.

(An obvious internal candidate for the job would be Yahoo’s Global Brand Marketing SVP, Allen Olivo, who could hit the road if not selected.)

Also a possibility is adding a COO with more Web experience to come in to help Bartz. There are plenty of candidates for that job all over the Internet sector.

But Bartz seems to be the kind of exec who favors flying solo and having key execs report to her to keep a finger on the pulse of a company. She is most definitely not going to have an entourage around her.

In fact, said one person familiar with the situation: “It’s long past time for new plumbing, and [Bartz] seems ready to flush a lot out that has long needed to go.”

YAHOO! ANNOUNCES REALIGNMENT TO SUPPORT CORE STRATEGIES

“These moves accelerate the ability of our deep and talented team to build great products, grow our audiences and improve monetization globally,” said Jerry Yang, CEO. “They are designed to put us in an even better position to leverage our leading global audience and capture the opportunity we see in the convergence of search and display advertising.”

Business and Product Changes

Yahoo!’s Marketing Products Division, Connected Life and Corporate Marketing groups will continue to operate as they do today.
