In 2008, Americans consumed information for about 1.3 trillion hours, an average of almost 12 hours per day. Consumption totaled 3.6 zettabytes and 10,845 trillion words, corresponding to 100,500 words and 34 gigabytes for an average person on an average day. A zettabyte is 10 to the 21st power bytes, a million million gigabytes. These estimates are from an analysis of more than 20 different sources of information, from very old (newspapers and books) to very new (portable computer games, satellite radio, and Internet video). Information at work is not included.
How Much Information?
PKM and Information Overload
Personal Knowledge Management (PKM) was developed as a workshop for students in MBA programs at The Anderson School at UCLA. The Anderson School's MBA programs present significant challenges to incoming students: a heavy workload, limited time, extensive and diverse informational resources, and an advanced technological environment that includes a laptop requirement for each entering student. The workshop aimed to teach students practical methods for managing their work and school-related activities and meeting the challenges of a rigorous academic environment.Harold Jarche » personal knowledge management & wisdom
PKM consists of practical methods for making sense of the increasing digital information flows around us. There is no procedural method to go from data to wisdom. On this Stephen Downes and I agree; though he thinks I adhere to the DIKW model. That said, while this is a much better model than this , I think it stays true to the original ‘filtering’ vision, where you go from data to wisdom through successive filtering processes. And while there are different ways to think of knowledge – processed, procedural, propositional – this model I think adheres to a more basic view. Here are some images from a presentation on PKM I will be giving at our local university tomorrow and including in a workshop next week.
Personal knowledge management (PKM) is a collection of processes that a person uses to gather, classify, store, search, retrieve, and share knowledge in his or her daily activities ( Grundspenkis 2007 ) and the way in which these processes support work activities ( Wright 2005 ). It is a response to the idea that knowledge workers increasingly need to be responsible for their own growth and learning. ( Smedley 2009 ) It is a bottom-up approach to knowledge management (KM), as opposed to more traditional, top-down KM. ( Pollard 2008 ) [ edit ] History and Background Although as early as 1998 Davenport wrote on the importance to worker productivity of understanding individual knowledge processes (cited in ( Zhang 2009 )), the term personal knowledge management appears to be relatively new. Its origin can be traced in a working paper by Frand and Hixon ( Frand & Hixon 1999 ).
