e-Learn GORE & Objectiver at your own pace!

Welcome to the Objectiver Virtual Academy!

1. Training objectives

This course aims at getting you acquainted with Goal-Oriented Requirements Engineering and the Objectiver tool. You will learn not only the concepts of goal orientation (goals, requirements, agents, obstacles, ...), but also how to put them into practice for solving a realistic case study.  

The main benefits of this e-learning program are as follows:

  • the quality of the contents: contents have been elaborated by an acknowledged expert in goal orientation, who practises goal orientation for more than 15 years and still works in close cooperation with the University of Louvain (methodology) and the Objectiver designers.
  • a practical training: you will have the opportunity to understand how powerful goal orientation is by studying a realistic case study and by using the Objectiver tool. At the end of the training programme, you will be really acquainted with goal orientation.
  • tutoring: your training will be supervised in a non-intrusive way by a tutor to whom you will be allowed to ask questions and advices
  • the pleasure of learning: just sit down in front of your PC and follow the training at your own pace. If you face an unexpected impediment: no problem, no stress, you just suspend your session and resume it later on, when it is quite convenient for you.
  • it does not harm just this once, but here quality does come cheap: compare, on the one hand, the price for a full 10-day training programme with travel and accomodation expenses and, on the other hand, the price for this e-learning programme: it's clear-cut!
  • our blue planet will thank you for your ecological choice...!

2. Training contents

This section gives an overview on the course contents and explains how the course is structured.   

2.1 Chapters

The course is structured in chapters. The following table provide information on the content of each chapter:






This chapter starts by presenting the prerequisites for this course (see below). Then, the case study that will be elaborated is presented.
You will also learn some basics about Objectiver.


What are goals?

This chapter introduces the concept of goals, which is central to goal orientation.
Goals are first defined and illustrated on several domains.
Then we apply the concept on the case study to start eliciting goals.
Finally, we will show you how to create goals in Objectiver and how you can trace them back to source documents.


Goal refinement

This chapter explains the concept of refinement:

  • how to structure goals from the most abstract to the most operational one
  • how to build refinements by asking the HOW and WHY questions on goals
  • what are the notations for refinements
  • AND-refinements and OR-refinements
  • the bottom-line: requirements, expectations, domain properties and hypotheses
  • tactics for decomposing goals in a systematic way


Conflicts and obstacles

This chapter introduces two important concepts of goal orientation:

  • conflicts
  • obstacles

These concepts are first carefully defined and illustrated on examples.
The case study is extended to take those concepts into account in the modelling process. You will then see how it is fundamental to reason about conflicts and obstacles to achieve a realistic and complete requirements document.



A good requirements document does not consist only of goals and requirements. We also need to provide a precise definition of the terms that are specific to the requirements document.  This is a necessary condition for avoiding misunderstanding, ambiguities and to favour a common vocabulary during the development project.

This chapter is dedicated to domain concept modelling. You will learn how to define terms and how to make them appear in the requirements document.


Validating the model

In this chapter, the techniques used to validate a model are studied. Validation takes place before writing the requirements document so that the requirements engineer is sure that the requirements document he/she will write is almost correct and complete.


Deriving a requirements document

This chapter focuses on requirements document generation. You will learn how to extract information from the model and how to use predefined generation assistants.


Concluding remarks

This chapter concludes the lecture by drawing some lessons from it.

2.2 Modules

Each chapter is decomposed into modules. There are four categories of modules:

  • Theory. The modules in this catagory aim at introducing the concepts on which the chapter focuses.
  • Case study. The modules in this categoty apply the concepts on the case study developed all along the course
  • Tool. The modules in this category focus on the use of Objectiver; important functions and steps are detailed.  Movies show you how to use the tool to model the case study. 
  • Quizz. You will have the opportunity to test how well you have assimilated the concepts studied in the chapter.

2.3 Case Study

The case study is about the management of a car park system with automatic barriers and time-stamped tickets. The case study has been selected for the following reasons:

  • The system is easy to understand even if we have never experimented it.
  • The requirements for this system seem easy to set up, but in fact, the study of the system with goal orientation in mind will reveal things we probably would have overlooked!


The requirements document you will get at the end of the course is  about 125 pages long, describes the requirements and the expectations by grouping them in 46 topics. The model contains 135 properties expressing what is required from the future system and what is expected from its interacting environment.

2.4 Roadmap

You are free to follow the chapters and the modules in any order. However, if you are a novice to goal orientation, a roadmap showing the order we advise is given in each chapter in order to help you approach the modules.  The following figure is an example of roadmap you will find in the course:

3. Prerequisites

This section explains what we are expecting from you.

3.1 About you...

We are expecting from you that

  • you understand the kind of problem, Requirements Engineering is addressing;
  • you can use some "standard" software tools like a word processing editor, a graphical editor (as in Microsoft Powerpoint for instance), and so on.
  • you are very motivated to learn goal orientation. To ensure a good follow-up of learners, the number of simultaneous subscriptions will be limited.

We are NOT expecting from you that

  • you are an expert in modelling
  • you already know other modelling approaches or techniques for building requirements documents.

3.2 Companion book

van Lamsweerde's book is a perfect companion book for this course. You will find it complementary readings and input allowing you to consolidate your knowlegde.

3.3 Objectiver

You will receive an evaluation, time-limited copy of the Objectiver software. The license key will be provided at activation time (see below).

3.4 Copyright, license agreement and obligations

By subscribing to the course, you shall commit yourself to comply with a set of rules described in the following document.
