The document discusses the phenomenon of information overload, revealing that in 2010, 1.2 zettabytes of digital information were created, with predictions of this number rising to 1.8 zettabytes by 2011. It highlights the significant costs related to productivity loss, estimating that information overload costs the U.S. economy at least $900 billion annually, with workers spending nearly half their day managing information. The effects of information clutter are further analyzed, showing that knowledge workers are often overwhelmed and distracted, impacting their ability to create value for employers.
Information Overload Phenomena
- 1. INFORMATION OVERLOAD Summary The customer sought information was articles, reports, studies on the ―Information overload phenomena‖. The researcher has categorized information as Information overload, data traffic and information consumption. Comprehensive research was conducted as per customer requirements through separate searches. To view details of the methodology undertaken and challenges encountered within the process of this research: please click The summary of the findings are as follows: Section 1 - Information Overload In 2010, 1.2 zettabytes of digital information will be created, according to a new "Digital Universe" study from IDC sponsored by IT firm EMC Corporation. International Data Corp. reports that the digital universe will hit 1.8 zettabytes (a zettabyte is 1 billion terabytes) by 2011. Information Overload would be the 2008 ―Problem-of-the-Year.‖ Overload costs the U.S. economy a minimum of $900 billion per year, it appears that it will be 2009’s problem as well. Workers spend up to 50 percent of their day managing information. Section 2 - Information Clutter Knowledge workers spend their days, according to Basex: - 28%-Unnecessary interruptions followed by "recovery time" to get back on track - 25%-Creating content-productive! - 20%-Meetings-some productive, some not - 15%-Searching for information (and an estimated 50% of searches fail) - 12%-Thinking and reflecting Reducing the time wasted dealing with information overload by 15% could save a company with 500 employees more than $2 million a year. Cutting the wasted time by just 15% through automation would save U.S. enterprises more than $270 billion. 62 percent of professionals report that they spend a lot of time sifting through irrelevant information to find what they need; 68 percent wish they could spend less time organizing information and more time using the information that comes their way. In an 8.89-hour average workday, employees said they spent 7.89 hours conducting research, attending meetings and searching for documents, the survey found.

Summary Section 2 - Information Clutter Contd Conservative estimates by IDC suggest that an organisation with 1,000 employees wastes at least $2.5 million per year by failing to find existing information, searching for outdated information, or recreating information that is outdated and poorly designed. Highlights of the average number of hours spent globally per week by knowledge workers on the four main business activities include: 9.00 hours a week is spent on preparing, running and summarising actions for meetings while 6.78 hours are spent managing and consolidating information such as documents, emails and web research. UK comes last in information management, spending 7.08 hours per week, with France spending 6.69 and Germany 5.91 hours. Section 3 - How Information Overload Affects Employers Harvard Business Review found that the average worker today spends 40% of the work day merely processing information. This translates into only 60% of the average work day being spent on true value creation activities. 40% of the payroll costs are spent handling the overload. The more time spent on processing information and not creating value, the less a company earns. Employees lose 28% in distraction which is their time at full pay that they aren't producing any value for the employer. Manager’s report spending an average of 42% of their time on administrative tasks. The administrative overload is greatest in Spain and the United Kingdom. The analysis also found that for every 1 point reduction in the amount of supervisors’ available time, worker unproductive time falls by 0.1 percentage points. Section 4 – Data Traffic The rapid growth of data consumption is real, has been observed by many operators. Growing problem of mobile data consumption vs. revenue: perhaps 100X growth of aggregate data vs. 2X growth of revenue (in the next 5 years) App Store, has defined a model of data services on demand that is widely appealing, with 500 M downloads in less than a year of operation, establishing that there is a large market for data services. 2

Summary Section 5 - Information Consumption 5.1 U.S Information Consumption Roughly 3.6 zettabytes (or 3,600 exabytes) of information were consumed in American homes in 2008. The big winner is still television at almost 45 percent of our daily allowance, but the computer is a not- too-distant second at about 27 percent. In all, we spend about 11.8 hours per day absorbing mass quantities of information, sometimes multitasking in front of multiple screens simultaneously. 5.2 Metadata In 2008, non-textual media storage requirements (audio, music, images, and video) were an estimated 16 exabytes. (An exabyte is a billion Gbytes.) Subscription-based and download media sales totaled $3.3 billion in 2008 5.3 Data Superabundance Enterprise Data Growth in the next 5 years is estimated to be 650% 80% of this data will be unstructured data 40 exabytes* of unstructured new information will be generated worldwide in 2009 IDC estimated the amount of data stored worldwide in 2007 was nearly 300 exabytes, and that this number will grow ten-fold by 2011. Methodologies and Challenges Search was directed towards details about Information Overload. The researcher has provided a global outlook of information overload from the productivity perspective. However, most of the studies conducted mainly concentrated on USA. The researchers have extracted information from several sources. This was quite time consuming as an extensive reading of articles were required. The researcher spent maximum time utilized for the query. 3

Section 1 – Information Overload Article 4 - Calculating Information Overload – Find out Your Organization’s Cost Key Facts A year ago, Basex announced that Information Overload would be the 2008 “Problem-of-the-Year.” Now that we know that Information Overload costs the U.S. economy a minimum of $900 billion per year, it appears that it will be 2009’s problem as well. Information Overload causes: - Markedly lower productivity, - Diminished comprehension levels, - Compromised concentration levels, - Less innovation. According to a recent Basex survey, it also causes health problems: 35% of knowledge workers experience work-related back and/or neck pain, carpal tunnel syndrome, eye strain, headaches, or stress related symptoms.

- 8. Information Overload Reported on: 25-03-2010 athandz Contd. Section 1 – Information Overload Article 5 - Information Overload: Now $900 Billion Key Facts Information overload describes an excess of information that results in the loss of ability to make decisions, process information, and prioritize tasks. It remains a key challenge for companies that operate in the knowledge economy but it is nothing new. Indeed, it was very much on the minds of thought leaders of an earlier information age centuries ago, including Roger Bacon, Samuel Johnson, and Konrad Geßner whose 1545 Bibliotheca universalis warned of the “confusing and harmful abundance of books” and promulgated reading strategies for coping with the overload of information. Workers spend up to 50 percent of their day managing information, according to a recent survey conducted by Basex of more than 3,000 knowledge workers, and streamlining these processes can have a significant impact on productivity. But determining the extent of the problem is the first step. Information Overload costs the U.S. economy a minimum of $900 billion per year in lowered employee productivity and reduced innovation. Despite its heft, this is a fairly conservative number and reflects the loss of 25% of the knowledge worker’s day to the problem. The total could be as high as $1 trillion.

Section 2 – Information Clutter Article 2 - Growth of Enterprise Information Key Facts Each year the amount of information created in the enterprise, paper and digital combined grows faster than 65%. Non-productive information work, such as reformatting documents or reentering documents into computers, consumed more than $1.5 trillion in U.S. salaries last year. Survey respondents spend as much as 26% of their time trying to manage information overload. Respondents split their time evenly between dealing with paper and digital information, but 71% prefer to deal with digital information. The amount of time U.S. information workers spent last year managing paper- driven information overload cost $460 billion in salaries. Respondents whose companies do a good job managing information overload rate technology as a significant help. Reducing the time wasted dealing with information overload by 15% could save a company with 500 employees more than $2 million a year.

Section 2 – Information Clutter Article 10 - Mindjet’s Value of an Hour Survey Reports Continued - Dramatic Results Key Facts Mindjet’s global productivity survey of 2,000 knowledge workers has identified key areas where information overload impacts performance and has calculated that individuals can increase productivity by at least 3-5 hours per week, depending on their organisational role and the time they spend on business activities. Conservative estimates by IDC suggest that an organisation with 1,000 employees wastes at least $2.5 million per year by failing to find existing information, searching for outdated information, or recreating information that is outdated and poorly designed. The opportunity costs are even greater, exceeding $15million annually. Highlights of the average number of hours spent globally per week by knowledge workers on the four main business activities include: 9.00 hours a week is spent on preparing, running and summarising actions for meetings while 6.78 hours are spent managing and consolidating information such as documents, emails and web research. For communication and collaboration such as building power point presentations, writing documents with others and communicating the results to colleagues takes 5.74 hours per week. Finally, 10.70 hours is spent on project and task management. European results show that the knowledge worker in the UK is slightly more efficient than the rest of Europe in managing meeting effectiveness, spending 7.83 hours per week as opposed to 9.55 hours in Germany. However, the UK comes last in information management, spending 7.08 hours per week, with France spending 6.69 and Germany 5.91 hours. For communication and collaboration, the UK with 5.38 hours does slightly better than France’s 5.70 hours and worse than Germany’s 4.72 hours. When it comes to project management, Germany is supremely efficient spending 9.15 hours per week against the UK at 11.16 hours and France at 11.33 hours.

Information overload can have a devastating effect on company earnings, and the danger is even more detrimental if it goes unrecognized. A company comprised of overloaded individuals is going to experience high turnover, low job satisfaction, missed financial forecasts, unproductive meetings, high error rates in work products, operation at a frantic pace, and high levels of rework. A recent study published in Harvard Business Review found that the average worker today spends 40% of the work day merely processing information. This translates into only 60% of the average work day being spent on true value creation activities. 40% of the payroll costs are spent handling the overload. The more time spent on processing information and not creating value, the less a company earns. Source: http://speedwithpurpose.com/overload.aspx Article 2 - Tech Giants Tackle Information Overload A large corporation in the tech industry has tens or hundreds of thousands of people, and if they lose 28 percent of their time to distraction, that's 28 percent of their time at full pay that they aren't producing any value for the employer. The corporations have to think about that, too. Companies also have to think about balancing their employees' lives. Information overload outside of work, like using a BlackBerry on weekends or vacations, could hinder the work-life balance, leading to decreased worker satisfaction. Zeldes also points out the problem is not just affecting technology companies or large corporations.

More Subscribers on Mobile Internet Data Plans - Developed markets will easily see 40% of subscribers on a data plan by 2012, most on a ―Flat Rate‖ plan that encourages use (without a penalty of incremental cost for incremental use) - This trend is so strong that mobile Internet subscribers are expected to outnumber fixed Internet subscribers in 2011. More Capable Internet Devices - IPhone has redefined how subscribers can use the mobile Internet, and established that the masses can and will browse, use Location-Based Services, watch YouTube video, download and install applications, and more. - By 2011, 30% of the handsets sold in developed markets will be smartphones. More Services Used - End Users are consuming more services as a result of better devices and a wider variety of applications. Example, Apple’s App Store, has defined a model of data services on demand that is widely appealing, with 500 M downloads in less than a year of operation, establishing that there is a large market for data services. 25

Information Overload Reported on: 25-03-2010 athandz Section 5 - Information Consumption 5.1 U.S Information Consumption Americans spend a huge amount of time at home receiving information, an average of 11.8 hours per day. Bytes of information consumed by U.S. individuals have grown at 5.4 percent annually since 1980, far less than the growth rate of computer and information technology performance. Roughly 3.6 zettabytes (or 3,600 exabytes) of information were consumed in American homes in 2008. Americans spend 41 percent of our information time watching television, but TV accounts for less than 35 percent of information bytes consumed. Computer and video games account for 55 percent of all information bytes consumed in the home, because modern game consoles and PCs create huge streams of graphics. The average American consumes 34 GB worth of content a day, including a whopping 100,000 words of information. The report clarifies that we don’t necessarily parse a full 100,000 words per day, but that rather astounding figure does cross our eyes and ears each 24-hour interval via multiple channels: the Web, TV, text messaging, radio, video games and more. The big winner is still television at almost 45 percent of our daily allowance, but the computer is a not-too-distant second at about 27 percent. In all, we spend about 11.8 hours per day absorbing mass quantities of information, sometimes multitasking in front of multiple screens simultaneously. Hourly Information Consumption 27

(An exabyte is a billion Gbytes.) Subscription-based and download media sales totaled $3.3 billion in 2008 British independent TV network broadcaster ITN adds more than 20 hours of broadcast-quality video to its archives every day, and it’s just one of hundreds of global broadcasters doing so. Web 2.0 users add 20 hours of video to YouTube’s archives every minute. Currently, none of this media is easily searchable. Video in particular is hard to search because most of the material is not indexed in a searchable way.

The data storage, archive, and backup of large volumes of digital content is quickly creating demands for multi-petabyte storage systems (equal to thousands of terabytes or millions of gigabytes), but today’s storage industry -- and its technological approach -- is not set up to effectively meet this demand. The beauty of dispersal is that as storage increases, the cost per unit of storage does not. Dispersal also meets the same reliability target. The table below best illustrates a generic example of cost savings between dispersal and replication when fixing the cost at a representative, but not necessarily actual, ―raw” storage cost of $2.75 per GB.
