Module 1: A Digital World
Chapters 1 & 4
1.1 What is an Information System?
Technical perspective: the Information
System (IS) artefact. An Information System
can be defined technically as a set of
interrelated components that collect (or
retrieve), process, store, and distribute
information to support decision-making and
control in an organization
The organizational perspective on
information systems goes beyond the IS
artefact, understanding an information
system to include not just hardware and
software, but also the data, the
organizational processes, and the people
involved in its use. The organizational
perspective analyses information systems as
sociotechnical systems at the intersection of
technology, organizations, and management.
1.2 What is Digitalization?
Information systems as a management discipline emerged in the 80s/90s both in the US (more organizational
tradition) and Europe (more technical tradition). IS researchers analysed how information technology and systems
can support business operations, organizational processes, and value creation.
Reflected in the creation of IT departments as cross-functional support units
Strategic relevance of IT support and process redesign, leading to creation of executive positions (Chief
Information Officer and similar)
The concepts of digitalization and digital transformation shift the role of digital technologies from support to being the
core value proposition. The job description of a Chief Digital Officer (or similar) is very different from a CIO, as s/he is hired to
fundamentally transform the core of a company’s business, products and services.

, 1.2.1 IT Transformations
Information Technology is at the intersection of, and transforms all sectors:
Accounting Finance Marketing Operations HR
Virtually all accounting Cryptocurrency Technology fundamentally Supply chain Social media channels
data is handled High-frequency trading changed the marketing management Freelancing,
electronically Tech companies landscape Process outsourcing &
Leaks represent vast share of Social media channels, engineering changing nature of
Data security & recent M&As ubiquitous IT (cf. minority Automation, work
veracity (Mergers & Acquisitions) report) internet-of-things Lifelong learning
Data, data, data (IoT)
Example of a fintech unicorn (=startup, privately held company valued at >1bn$): Adyen, focused on
building modern infrastructures directly connected to card networks and local payment methods across
the world, allowing for unified commerce and providing shopper data insights to merchants. They
enabled revenue growth online.
In terms of payment platforms, there is growing competition for payment integration & facilitation… PayPal, Alipay,
Amazon Payments, Klarna, iDeal, Strip, Visa/MasterCards, Classical banks…
1.3 An Algorithmic World
Algorithm: a procedure for solving a mathematical problem
(as of finding the greatest common divisor) in a finite number
of steps that frequently involves repetition of an operation.
Broadly: A systematic procedure for solving a problem or
accomplishing some end.
Modern life is fundamentally governed and influenced by
algorithms, including:
• Advertisements you are exposed to (Facebook, Google, Netflix)
• People we elect for office (Cambridge Analytica scandal)
• How the economy is run (algorithmic trading, automated
supply chains)
1.3.1 Algorithmic Accountability
Algorithmic systems are increasingly used as part of decision-making processes, with potentially significant
consequences for individuals, organizations and societies as a whole. Increasing concerns that many of these systems
are opaque to the people affected by their use and lack clear explanations for the decisions they make. This lack of
transparency risks undermining meaningful scrutiny & accountability:
Significant concern when these systems are applied as part of decision-making processes that can have a
considerable impact on people's human rights. Examples include critical safety decisions in autonomous vehicles;
allocation of health and social service resources, etc.
Algorithms in social media influence politics & the formation of public opinion…
