CSE1720 Summer 2005 Lect 01 / 48 Why Organisations Invest In Information Projects  High probability of achieving benefits  Good accounting rate of return  Meets technical/system requirements  Supports legal/government requirements  Good profitability index  Introduces new technology

CSE1720 Summer 2005 Lect 01 / 49 The Information Age Some characteristics: The computer is the dominant technology Computing intelligence is dispersed into all aspects which can be improved by being ‘smart’. Computerisation is called mechatronics (mechanical electronics) Technology gives products the capability to be customised and made responsive to each user

CSE1720 Summer 2005 Lect 01 / 50 The Information Age The output of the current period is knowledge Products which are ‘information rich’ produces products which have a high level of attraction to users The basis of wealth is information. Information drives the creation of knowledge > which drives strategic actions > which create temporary competitive advantage for businesses.

CSE1720 Summer 2005 Lect 01 / 51 The Information Age The ‘knowledge worker’ is the key to information A large part of the workforce is involved in collecting, processing and communication information The means of ‘moving things’ is communications networks Logistics is concerned with moving bits representing data and information as opposed to moving physical products

CSE1720 Summer 2005 Lect 01 / 52 The Information Age The market place (where people gather to buy and sell products and services) has shifted from the physical marketplace to the marketspace - which is an electronic market place in cyberspace) Information based improvements become the main method of creating new products and services The value of existing goods and services is enhanced by information enhancement

CSE1720 Summer 2005 Lect 01 / 53 And the Customers ? Customers are marketed, sold and serviced as individuals, not as statistical averages An accessible information highway, the Internet, permits global and interactive access to multimedia information

CSE1720 Summer 2005 Lect 01 / 54 And People ? Convergence of information forms leads to ‘new’ ways of working and living Time and space constraints of markets collapse People live where they please They work with remote employers They purchase products from local or distant providers as required

CSE1720 Summer 2005 Lect 01 / 55 The Industrial vs the Information Age Industrial Age : Information flow was physical and paper based Information Age : Information flow is virtual and digitised The result is the movement from manufacturing to knowledge as the key to societal wealth The end result is the global economy becoming merged and information-centric = globalisation ?

CSE1720 Summer 2005 Lect 01 / 56 The Information Age 5 Primary Perspectives: 1. Technology Continued innovation in information technologies results in information technology addressing all forms of life 2. Economics The economy becomes information-centered. The creation of wealth is tied to the ability to create new information-based products and amend existing products with information 3. Employment There is a shift in numbers to knowledge workers. People make their living in creating, moving, analysing, interpreting or distributing information

CSE1720 Summer 2005 Lect 01 / 57 The Information Age 4. Spatial World networking of computers leads to the collapse of the traditional market constraints of time and space. The world becomes a global marketspace 5. Cultural Society becomes media-laden. Information is readily available in multimedia formats, it can be customised easily and accurately, and it is interactive We expect information in forms which are readily accessible and convenient

CSE1720 Summer 2005 Lect 01 / 58 The Information Age 3 associated technology changes drive the information age 1. Digitisation of information - regardless of form (audio,data, image, video) All information shares the same basis of construction It becomes transportable interoperable subject to interactive manipulation by the user

CSE1720 Summer 2005 Lect 01 / 59 The Information Age 2. Rapidly decreasing cost of computing This ensures that computing will become – available – available everywhere (ubiquitous) – cost attractive 3. Broadband Communications Multimedia is storage intensive and time sensitive Gigabit communications (lecture 8) will give rise to efficiency and effectiveness of work

CSE1720 Summer 2005 Lect 01 / 60 The Information Age Business is highly competitive Success is the objective Success can be achieved by advantage Advantage is expressed through the power and agility of information technology I.T. is now not seen as an expense - it is the means of attracting customers adding value to products improving productivity beating the competition
