ArchiMate 3 in practice

ArchiMate 3 in practice

Orsys training, Belgium (2022). This 2-day on-site training introduces ArchiMate, an open enterprise architecture modeling language to support the description, analysis and visualization of architecture within and across business domains. ArchiMate offers a common language for describing the construction and operation of business processes, organizational structures, information flows, IT systems and technical infrastructure.

Day 1

Main topics:

  • ArchiMate 3.0: Core Framework, standard and benefits;
  • The Open Group Architecture Framework (TOGAF);
  • Elements: aspects and relationships;
  • Business layer: essentials and hands-on;
  • Application layer: essentials and hands-on;
  • Information structure;
  • Cross-layer relationships.

Day 2

Main topics:

  • Technology layer: essentials and hands-on;
  • ArchiMate: layered and total views;
  • ArchiMate viewpoints;
  • Motivation view;
  • Services in ArchiMate;
  • Vertical slicing through the layers.

Identity proofing

Identity proofing

Zetes project @Brussels, Belgium (2021). Identity proofing consists in verifying for a given level of assurance that a person, who is claiming an identity, is indeed the correct person. This identity proofing process can be performed manually by a human operator, either on site (through physical presence) or online (remotely through videoconference), but also automatically (e.g. fully automated online or in a controlled environment).

At the European level, the European Telecommunications Standards Institute (ETSI) is working on technical specification ETSI TS 119 46 to lay the foundations on a new identity proofing standard, whose aim is to be applicable in areas such as the issuance of electronic identity (eID) and Know Your Customer (KYC) processes, with several person types considered: natural person, legal person, and natural person representing a legal person.

One of the objectives of this specification is to provide controls against two main identity proofing threats:

  • Falsified evidence: A person claims an incorrect identity using forged evidence;
  • Identity theft: A person uses valid evidence associated with another person.

Therefore, implementing identity proofing requires a risk-based and outcome-based approach where requirements can be tuned up to a desired level of assurance (i.e. degree of certainty) of the result, depending on the context (e.g. purpose of the identity proofing, regulatory environment, acceptable risk regarding the result of the process).

In this project, my tasks are related to the analysis of technical specification ETSI TS 119 46 so as to investigate what parts of the identity proofing process are already developed and available at Zetes (and therefore could be reused), how the missing parts can be implemented in practice and what are the possible impacts of the implementation on the existing products and solutions.

Business process and decision modeling

Business process and decision modeling

HPI training, MOOC (2021). This online training introduces concepts of business process modeling using the Business Process Model and Notation (BPMN) industry standard. Based on a thorough understanding of BPMN, the last part of the training covers decision models using the Decision Model and Notation (DMN). Decision models complement process models by representing concrete, operational decisions, both with their structure and their decision logics.

Week 1: Introduction to business process management

Main topics:

  • Defining business processes;
  • Business process models;
  • Interacting business processes;
  • Models and instances;
  • Business process lifecycle.

Week 2: Basic business process modeling

Main topics:

  • Process activities;
  • Exclusive and parallel gateways;
  • Inclusive gateways and loops;
  • Start, intermediate and end events;
  • Concurrency.

Week 3: Analyzing the behavior of process models

Main topics:

  • Process behavior;
  • Structural soundness;
  • Simulating business processes;
  • Petri nets and process analysis;
  • Checking soundness.

Week 4: Advanced business process modeling

Main topics:

  • Sub-processes and boundary events;
  • Activity modifiers;
  • Event-based gateway;
  • Modeling organizations;
  • Resource allocation patterns.

Week 5: Data in business process models

Main topics:

  • Organizing process models;
  • Data and data flow;
  • Data execution semantics;
  • Structured data and sub-processes;
  • Object lifecycle conformance.

Week 6: Business decision modeling

Main topics:

  • Implementation of decisions;
  • Decision requirements diagrams;
  • Semantics of decision tables;
  • Analysis of decision tables;
  • Consistency of processes and decisions.

UML class diagrams

edX training, MOOC (2020). This online computer science training from KU Leuven (BE) provides an in-depth understanding of Unified Modeling Language (UML) class diagrams, which are used to visually represent the conceptual design of a system. The training presents UML class diagrams and explains how they are used to map out the structure of a business domain by showing business objects, their attributes and associations.

Week 1: Introduction

Main topics:

  • Why does data modelling matter?
  • Modelling languages.

Week 2: UML basics

Main topics:

  • Attributes and data types;
  • Class definitions;
  • Unary and ternary association;
  • Aggregation;
  • Derived and implicit association;
  • Parallel paths.

Week 3: UML advanced

Main topics:

  • Superclass, subclass and inheritance;
  • Generalisation sets;
  • Constraints on generalisation and specialisation;
  • Inherited associations;
  • AssociationClass;
  • Association reification.
