Requirements matrix in archimate

Structuring and graphically representing requirements can be challenging for large projects.  Today I figured out how to draw the equivalent of several pages in excel into one single archimate diagram.

The requirements are structured in 3 columns : requirement family, description and concerned stakeholders.

Using archimate I drew actors corresponding to stakeholders vertically, as a kind of first column. Then I drew all requirements families at the top as a kind of first line by using xxx of the archimate motivation extension.

Requirements can then be represented as a kind of cell in the actors/ family table.

In order to simplify the drawing and trace the requirements dependencies I used a simple association between actor and requirement and an aggregation relationship between requirement family and requirement. Actors can link to any requirement.

The result looks like this :



This needs to be done in several phases: after some modeling, clusters of requirements can be identified and the drawing can be reorganized by reordering actors and requirements to improve readability.

The next step will be to map requirements to the solution processes,  functions and components.…

The Design Thinking Process

Design Thinking is a process based on the collaboration between the users and a product designers to determine how to solve problems that the users have.

5 Steps to Build Perfect Web Sites Using the Design Thinking Process:

1. Empathy and Immersion

2. Define the Problems You want To Solve

3. Come Up with Ideas to Solve User Problems

4. Create Prototypes of Products to Solve the Users’ Problems

5. Test the Products with your Users

An event I’d like to attend

– Meet new people
– Learn something
– Have a drink
– 18H20 Welcome with soft drinks
– 18H30 First technical talk by a peer who is a specialist in some field (20 min + max 5 min Q&A)
– 18H55 Second technical talk by a peer  (20 min +5)
– 19H20 20 minutes Break (softd drinks + sandwish for those already starving)
– 19H40 Talk by a special guest – ex: success story and lesson learned by top guy/women (between 30 and 45 minutes)
– 20H30 – Drink + something small to eat
–> 3 talks ==> more people interested and not boring+ you can arrive late or leave early
–> 3 breaks ==>  meet people and discuss is often the best part…


Here is the DIGB-SA study Archimate model that has been built with Archi 2.6:

If you don’t want to install Archi, you can have a look at the model here:

I have received the authorization from my clients to publish it in order to:

  • Encourage the modeling practice and reuse among public libraries
  • Share with the Archimate community as an example

The model reuse is subject to the following  restriction:


This model is published for reuse by public libraries. It can’t be marketed, sold or resold.

This model has been developed by Jean-François Declercq in the context of the DIGITAL LIBRARY SYSTEM ARCHITECTURE study by ordered by:
– Bibnet vzw
– Vereniging van de Vlaamse Provincies
– Vlaamse Gemeenschapscommissie van het Brussels Hoofdstedelijk Gewest


PS: A Dutch version of this model is available at Bibnet (…

Study Published: the system architecture of the digital public library

26 march 2014

The reports of  the study on the current and future system architecture of the  digital library have been recently published.

The term “digital library” is here used as a collective name for all of a library’s products, processes and services that are digital and/or automated.

The study summary lists the future work zones for the  Flemish Public libraries:

  1. Business intelligence (BI)
  2. IT maturity
  3. Web presentation
  4. Identity and Access Management (IAM)
  5. Digital Collections
  6. Collection Management and cataloguing
  7. Architecture consolidation (SOA)

The summary is available in French, Dutch and English:

The complete study has three main chapters :

  • Current system architecture of Flemish public libraries (AS-IS)
  • Evolution of the Flemish public libraries’ System architecture (change requirements)
  • The Future system architecture of Flemish public libraries (TO-BE)

The future system architecture is in fact a generic future-proof ICT blueprint for a public library. The blueprint is a set of business services, business processes, Applications, SOA Services and technological elements documented in the Archimate notation.

Business Services Overview

The complete study is available

I would like to thank the colleagues who worked with me on this study:

  • François Vermaut (IT Strategy, BPM, SOA, ITIL…)
  • Rosemie Callewaert (Public Library field expertise, User Experience, BIBFRAME, FRBR…)
  • Simon Kroeger (Proof reading english text)
  • Veerle Vanlooy (Vertalingen Vanlooy)

I also would like to thank the steering commitee (Bart Beuten, Jan BraekmanPatrick Vanhoucke ,Stefaan Froyman), all the workshop and participants. Their input has been key. I would like also to thank Alexandre Lemaire who helped me to compare the Flemish situation with the situation of the Fédération Wallonie-Bruxelles.…
