Can Silicon Valley’s most disruptive firm prosper without its maker?

Steve Jobs resigns

The minister of magic steps down

Can Silicon Valley’s most disruptive firm prosper without its maker?

IN A commencement speech to students at Stanford University in 2005, Steve Jobs, the chief executive of Apple, advised his audience to avoid being trapped by dogma and to have the courage to follow their hearts and their intuition. “Stay hungry. Stay foolish,” he said as he signed off. By following his own advice, Mr Jobs, who resigned as Apple’s boss on August 24th, has turned the company from a basket case on the brink of bankruptcy when he returned to its helm in 1997 into a world-beater that is reshaping a big chunk of the technology industry. Earlier this month, Apple even briefly surpassed Exxon Mobil, an oil giant, to become the world’s most valuable company.
No other boss in recent history has embodied and defined a firm as completely as Mr Jobs. So his decision to resign as chief executive has inevitably raised the question of whether Apple will remain as hungry and as wildly successful without its entrepreneurial maestro at the helm. Other giants in the tech industry have seen their fortunes fade after iconic leaders have departed. Microsoft has struggled to regain its mojo since Bill Gates stood down as its chief executive in January 2000. Could Apple suffer a similar fate?
That seems unlikely for several reasons. One is that the company has had plenty of time to plan for this moment. Mr Jobs has stepped aside from day-to-day management at Apple on a couple of occasions before, after having surgery for a rare form of pancreatic cancer in 2004 (see timeline). Each time, Tim Cook, Apple’s chief operating officer, temporarily assumed his boss’s responsibilities.
That allowed Mr Cook, who is taking over from Mr Jobs as CEO, to get a taste for the top spot—and it gave Apple’s board a chance to see him in action. On each occasion, Mr Cook kept Apple’s money-making machine ticking over smoothly. An expert in manufacturing and logistics, he closed down almost all of Apple’s manufacturing operations after he arrived at the firm in the late 1990s and outsourced much of these to Asia. Announcing his promotion, Apple’s board said that he had shown “remarkable talent and sound judgment in everything he does.”
Talent is something that Apple also has an abundance of elsewhere in its ranks. Executives such as Phil Schiller, who oversees the company’s marketing, and Jonathan Ive, a Briton whose domain is design, are part of a team that has worked closely together for many years. If Mr Cook can keep this group intact, then Apple’s future should be bright.
The firm also benefits from an intensely loyal and motivated workforce. Glassdoor, an online jobs and careers community, carries reviews of the company from almost 1,000 Apple employees. Most are glowing about the firm and in particular about Mr Jobs’s impact on it. One post even calls Apple’s former boss “the Thomas Edison of this century”. Paul Saffo of Discern Analytics, a financial-analytics company, reckons that this depth of loyalty will mean that even though Mr Jobs is stepping down, the firm’s employees will continue to ask themselves “what would Steve do?” when making decisions. (Of course, asking the question is easier than guessing the right answer.)

Another reason for optimism is that Mr Jobs is not disappearing from the scene entirely. Instead he is taking on a new role as the chairman of Apple’s board, which should allow him to keep weighing in on important decisions for some time to come, assuming that his health allows. Apple has a pretty clear product pipeline for the next couple of years, which is reassuring. The firm is due to unveil the latest version of its hugely successful iPhone in the coming weeks and is expected to launch a new iPad early next year.
But Apple is far more than the sum of the devices that it sells, impressive though they are. Its secret sauce lies in the integration of these with software and services such as its iTunes online content store and its recently announced iCloud online-storage offering. These form what tech types like to call an “ecosystem” that has proved so popular that it is forcing other companies to develop similar capabilities. Google, which has long excelled at developing software, recently splashed out $12.5 billion for Motorola Mobility so that it could get its hands on the firm’s smartphones, tablets and other devices. And Amazon, which has a huge cloud business, is planning to launch its own tablet computer to compete with Apple’s iPad.
The good news for Apple’s investors is that the firm has been given a great head start in the battle for dominance of this emerging tech landscape thanks to Mr Jobs, whose vision of the future has been honed over a long and tumultuous career. After co-founding Apple with Steve Wozniak in the 1970s, he went on to pioneer the era of the personal computer in the following decade. He was then ousted from Apple after a boardroom coup in 1985.
After that, Mr Jobs followed his heart and his intuition by building up Pixar, a film studio that specialises in computer-animated films. It has produced a string of hits, from “Toy Story” to “Finding Nemo”.
He returned to Apple as an adviser in 1996, when the firm was in dire straits. A year later he was made interim chief executive. Asked at the time what he thought Mr Jobs should do with Apple, Michael Dell, a rival computer-maker, helpfully suggested that he should shut it down.
Mr Jobs ignored that advice. Instead he led the company on to its greatest triumphs. Among them were the creation of the iMac, which revived the firm’s ailing computer business, and the development of the iPod, which ended up transforming the music industry. But just as important as what Apple did was what it did not do. Charles Golvin of Forrester, a research firm, says that one of Mr Jobs’s greatest skills has been to decide which projects the firm should not undertake.
It has been widely rumoured, for example, that engineers at Apple were urging its boss to create a tablet computer in the early part of the decade. But Mr Jobs turned a deaf ear to their entreaties and instead insisted that the company focus on producing a smartphone. The result was the iPhone, which transformed yet another market and is still minting money. In a creative cauldron like Apple, ideas are rarely in short supply. But the skill of choosing the right ones to focus on at the right time is rare. Mr Jobs has it. Apple’s shareholders will have to hope that Mr Cook does too.

England riots: What's the evidence gangs were behind the riots?

Gangs are being blamed for last week's explosion of riots and looting. But how do we know they were responsible?
The prime minister has promised a "concerted, all out war on gangs and gang culture", in response to the riots and looting across English cities.
A gangs taskforce is being set up, to be led by Home Secretary Theresa May and Work and Pensions Secretary Iain Duncan Smith. Bill Bratton, former police chief of Los Angeles and New York, is to advise the government on how to crack down on gangs.

But were gangs really to blame?
Here a number of experts and witnesses offer their view:

Yes: The riots were planned in advance by gangs

The speed and devastation with which the riots spread suggests they were organised.
Rioters in London Some argue that gangs were instrumental in co-ordinating the disorder.

This wasn't a general uprising, says Christian Guy, policy director at think tank the Centre for Social Justice. It was a well co-ordinated operation, which is likely to have been led by young people in street gangs, he believes.
Daniel Weston, a youth worker in Brixton, says gangs in his area bided their time after the first night of violence in Tottenham.
When they were ready to strike, gang leaders used Blackberry Messenger, a closed network not visible to police, to mobilise younger gang members. Targets were identified - typically Footlocker, JD Sports and Currys - and gang members directed to them.
Normally their business is selling drugs. But during the riots they "put that to one side to" to turn their attentions to looting, he believes.

No: It was a wide spectrum of society taking part

Not all criminal young people are in gangs. Gavin Knight, who spent long periods of time "embedded" with anti-gang units for his book Hood Rat, says many see gangs where none exist: "People see a teenager in a hoodie and think it's a gang."
Rioter in London Not all of those involved in disorder fitted the usual profile of a gang member
In reality, there are few genuine gang members. And "all sorts of people" - teaching assistants, a graphic designer and university students - have been arrested for taking part in the looting.
Paul Lewis, a Guardian journalist who spent five nights observing the violence, says it's wrong to try to put the blame on one group. Everyone's looking for a caricature yet those involved were a cross section of the local community. And each riot he saw - from Hackney to Gloucester - had a distinctive character.
"There were a great number of people swept along. The only generalisation that's credible is that on the whole they were young and poor," he says.

Yes: The gangs suspended turf rivalries to maximise the damage

Most gang violence is aimed at other gangs. But during the riots the gangs appeared to join forces.
Strict territorial divides preventing young people "slipping" into rival areas were temporarily forgotten. Weston says gangs were given a "hood pass" - a slang term meaning that youths were allowed to travel into another neighbourhood.
"The gangs came together and forgot their rivalries," he says. For once, gang members from Peckham, Brixton, Clapham and Tulse Hill, allowed other's young people to move around unhindered. The informal truce didn't last long however. There have already been attacks on rival gangs to steal looted gear, he says.

No: It wasn't gang unity but friends looking for excitement

The loss of control by police in Tottenham gave young people ideas. But they weren't part of gangs, just "excitable young kids" who were easily led, says Knight.
Blackberry Much has been made of the role of BlackBerry Messenger
"It was random, chaotic activity not a co-ordinated uprising." There was no truce between gangs, the looting was simply so chaotic that normal rules ceased to apply, he says.
A lot has been made of the importance of gangs using Blackberry Messenger. But Lewis - who was receiving the messages - says BBM was not "directly determining" the action but "loosely influencing events".
The messages were more likely to be sent between friendship groups than gang associates, he believes.

Yes: Looted goods were ferried away by gangs

There were widespread reports of organised looting with rioters sometimes queuing to take goods away.
Looters in Hackney, east London According to some reports, the looting was carefully orchestrated
Andrew Malone, special correspondent for the Daily Mail, spent two hours standing outside a Panasonic shop in Ealing. He describes a scene in which younger drug runners ferried the spoils to older gang members in nearby vehicles.
