IT – MODELING0. Course Organization & Outline
“Information technology and business are becoming inextricably interwoven. I don’t think
anybody can talk meaningfully about the one without talking about the other.”
Bill Gates
If you want a functioning business environment, you need information technology.
Information Technology: Modeling – What?
Need IT knowledge for business in 2023!
If you want to talk about business, you need to have some basic understanding of what
Information Technology is and what it can do for your business.
But…
– What is IT?
– What is information?
– What is a model?
– What is the impact on the organization?
– How can we develop such systems?
– How do I communicate requirements to the technical staff?
These questions and more… we will study.
Developing information systems is a matter of people
IT alignment : to develop an information system, a lot of people have to cooperate and
communicate with each other.
At each stage of communication there can also be miscommunication
Requirements can be mistranslated
Stakeholder preferences can be ignored

, Development processes are getting much more bigger and involve much more
stakeholders than before
Maintaining IT systems is not straightforward
Even when you have developed an information systems, things can go wrong because
those systems need maintenance.
Maintaining IT systems is not straightforward.
o Example : Facebook-Instagram-Whatsapp stopped working for several hours.
When your business are digital and depend on those applications or system you have built,
costs can be huge!
Course contents
IT Modeling introduces a range of concepts, methods and approaches that are being
employed by business analysts in the industry.
Business analysts operate on the interface between the business and the IT department in
order to analyse and describe requirements with regards to:
– the design,
– functionalities,
– development,
– and implementation
of business information systems.
Business analysts are becoming more and more the architects of “organizations”, designing
the processes and procedures and as such determining how an organization operates and
in fact is exactly organized.
o They facilitate the organization to change how its doing business,
o To make the operations more efficient,
o By adopting technology.
Topics that will be covered:
o Chapter 1: Information systems development WHAT
using the Systems Development Lifecycle (SDLC) HOW
o Chapter 2: Process modeling (BPMN) WHAT
using Business Process Modeling Notation (BPMN) HOW
o Chapter 3: Data modeling (Unified Modeling Language) WHAT
using the Entity Relationship (ER) model HOW
HOW : methodology
Specific Learning outcomes
At the end of this course, students should be able:
o To generally discuss the development of an information system using the SDLC, and
the use of process and data modeling
o To discuss and illustrate the various uses of process models within organizations and
be able to apply a process modeling technique (BPMN) to describe and analyse
businesss processes;

, o To apply a conceptual data modeling technique (ER modeling), to capture and
analyse the basic information requirements for an enterprise domain, and
understand its broad use within an organization;
Practical uses outside of Information System Development
Basel IV reporting -> what financial service providers need to report to the ECB to
determine their required capital reserves.
o Risk & capital reserves in financial industry
o Tools used:
Process modeling
Data modeling
At your job:
o Insight into business/IT interface

For your thesis
Broader use : business/IT alignment
You are operating in the intersection between business and IT.
Business usually determines the direction : macro-perspective, strategy, where you want to
go.
IT technology : a selection of tools that can help you achieve your goals as outlined by
business.
To alignment between those pieces of technology that exists with what you want to
achieve is vital and also very complex
