Chapter 1: Managing the Digital World
Post-PC era: wireless, mobile devices allow for novel ways of interacting with information systems
• Five IT megatrends shape the way we work and interact
o Mobile, Social Media, Internet of Things, Cloud Computing and Big Data
o Success of the megatrends is based on the Network effect: the notion that the value of a
network increases with the number of other users (the more users, the more value)
Knowledge workers: professionals who are well educated; and create and modify knowledge as a
fundamental part of their jobs.
• Lines between knowledge workers and manual workers are blurring, to the point where every
worker is a knowledge worker
Knowledge society: society as a result of the growth in numbers of knowledge workers
• Information has become as important as land, labour and capital resources
E-commerce: the use of internet and related technologies to support commerce
E-business: use of nearly any information technologies or systems to support every part of the business
• Many traditional occupations use information technologies à every organisation is considered an e-
business
Digital Divide: those with access to information technology have great advantages over those without access
to it
Consumerisation of IT: employees use their own devices for work-related purposes; or use software they are
used to in the workplace
• Bring Your Own Device (BYOD): trend wherein workers use their own device for private purposes
(checking emails, social media) and tasks (customer relationship management, resource planning).

, o This can be worrying, or provide opportunities such as increased productivity and higher
retention rates of talented employees
Internet of things: broad range of physical objects (computers, sensors, motors) that are interconnected and
automatically share data over the internet.
Cloud Computing: use of internet as the platform for applications and data (e.g. accessed via web browser)
Waves of change: three distinct phases that have taken place in the past, or are presently taking place
within the world’s civilisation (Alvin Toffler)
Big Data: extremely large data sets that may be analysed computationally to reveal patterns, trends and
associations; especially relating to human behaviour and interactions
• Companies in the information era are creating value from data, not from people
Wearable Technology: clothing or accessories that incorporate electronic technologies (smart watch, fitness
tracker)
Computer Literacy: knowing how to use a computer à many argue it is not sufficient in this society, rather:
Computer Fluency: the ability to independently learn new technologies as they emerge and assess their
impact on one’s work and life
Information technology has enabled globalisation: the integration of economies throughout the world,
changing how people, organisations and countries interact
• Can be visible in
o Economic change: increase in international trade, outsourcing, development of global
financial systems and currency
o Cultural changes: increases in the availability of multiculturalism through tv/movies;
frequency of international travel, tourism, immigration; use of worldwide social media
o Technological change: the development of low-cost computing platforms and
communication technologies (skype, email); nature of low-cost telecommunication
infrastructure (internet)
Outsourcing: moving of business processes of tasks to another company
• Onshore: domestically
• Offshore: to another country
• Why outsource?
o Reduce/control costs
o Free up internal resources
o Gain access to world-class capabilities
o Increase the revenue potential of the organisation
o Reduce time to market
o Increase process efficiencies

, o Focus on a core activity
o Compensate for a lack of specific capabilities or skills
Information systems use information technology to collect, create and distribute useful data
• Information Technology: hardware, software, telecommunications network
• Good IS personnel possess knowledge and skill in three areas
o Technical: (hardware, software, networking and security)
o Business
o Systems (building and integrating systems, solving problems)
• Types of IS
o Transactions Processing Systems (TPS): efficiently process customer transaction and use data
for analytics
o Management Information System: where TPS data are sorted and organised to support
decision making
o Office Automation Systems: word processing, spreadsheets and other personal productivity
tools, enabling knowledge workers to accomplish their tasks (excel, word)
Data: most basic element of any information system à raw symbols
• No meaning in and of themselves
• Of little value until processed
• Can be formatted, organised or processed to be useful à transformed into information
• To use this information, knowledge is needed: ability to understand information, form opinions and
make decisions or predictions with the information
When systems cannot be categorised (e.g. supply chain management) they are referred to as:
• Internetworking: connecting hosts computers and their networks together to form larger network
• System Integration: connecting separate information systems and data to improve business
processes and decision making
Computer Ethics: moral issues and standards of conduct as they pertain to the use of information systems
Information privacy: what information an individual should have to reveal to others
Intellectual Property: creations of the mind that have commercial value (music, tv)
3D Printing: enables creating physical three-dimensional objects from digital models
Chapter 2: Gaining Competitive Advantage Through Information Systems
Business Processes: activities organisations perform to reach their business goals
