Samenvatting hoorcolleges Management en Informatiesystemen
Week 1 - Introduction
Information system (IS): the combination of people and information technology (IT):
hardware-software-communication that create/collect/process/store/distribute useful data
& information in an organization.
→ To build effective Information Systems, we need to understand what knowledge is
needed
Designing information systems:
• Data
• Hardware/Software/Telecommunications Networks (IT)
• People
• Organizations
Information management: the management of IT + business processes + people, to obtain a
strategic objective
Digital divide: we are very dependent on information and ICTs. People can be left behind in
the Information Age.
DIKW model
Van raw data naar de use of knowledge in decision
making processes (van weer-gegevens naar
beslissing bus/fiets)
Week 2 – Trends, intro to Business Intelligence

Mobile Het gebruik van mobiele devices
Implicaties: new way to reach
customers/different organization of
work/different payment methods

encourage employee collaboration/to
connect with their customers
Internet of Things Devices have embedded computers and

Big data & business analytics 5 V’s: volume-variety-velocity-veracity-
value
E-commerce Business, consumer, government (B2B, B2C,

to predict the rating/preference that a user
would give to an item (‘Consumers who
bought this also bought this’)
Dynamic pricing: flexible prices for
products/services based on current market
demands
Artificial Intelligence Two basic ideas:
• Studying the thought processes of
humans
• Representing & duplicating these
processes via machines
→ Chat bot
Blockchain A shared digital database to specify
contracts/transactions
• Fiddling with transactions not
possible (real-time copy)
→ Cryptocurrencty (Bitcoin)
→ Smart contracts: automated contracts
via blockchain, blockchain as trustmachine
(voting machines, registration of property,
savings account)
Introductie Business Intelligence/analytics
Data management: managing data as a valuable resource
→ Data production, assembly/logistics/storage, processing/analysis/consumption
Business intelligence: transforming data into meaningful information/knowledge to support
business decision-making
→ Van ruwe data naar iets bruikbaars/aantrekkelijks
1. Data
