Euromethod Principles |
|
| This document will give you an overview on the following topics: |
| Euromethod addresses a variety of changes to information systems, considering information systems as totalities of organisational, human and technical elements. This variety of changes, which include system development, is captured by the concept of information system adaptation. | |
| Euromethod applies to any information system adaptation that can be characterized by a well understood initial and final state. As a consequence, Euromethod can be reapplied at various stages during the life of the same information system. | |
| Euromethod supports the understanding, planning and management of the contractual relationships between a customer and a supplier of information system adaptations. | |
| Euromethod supports the development of a strategy and a plan for information system adaptation that is tailored to the specific characteristics of a problem situation. | |
| Euromethod focuses on the key decisions to be taken by the customer and the supplier, on their related transactions and on the key roles played by people (organisational actors) during these transactions. | |
| Euromethod is focused on the deliverables which are exchanged between the customer and the supplier. The deliverables constitute the key planning elements to support decision making and management of progress. | |
| Euromethod provides valuable concepts and guidelines to supplement information system development methods. Guidelines are offered to bridge between Euromethod concepts, on the one hand, and development method concepts on the other. |
In the following sections, these principles are discussed in more detail.

On the product side, information systems are considered as totalities of organisational, human and technical elementsas illustrated on Figure 2. Information systems contain information resources. These resources are used in processes performed by various actors within the organisation. Different kinds of technologies, one of the most important being computer systems, are developed to support the involved actors and to automate part of the processes involved. As a consequence, the scope of Euromethod is wider than software development: it is concerned with improving the information system in all its aspects.
On the process side, Euromethod addresses a variety of information system changes including their modification (correction, enhancement, improvement, etc.) and automation to fulfill the changing needs of the organisation. This variety of changes, for the purpose of Euromethod is captured within the concept of IS-adaptation .
A fundamental distinction is made between two types of activities involved in all these kinds of adaptations:
Production activities: which perform
the actual adaptation work through documentation, change study, design,
test, installation of the information system.
Management activities: which control
the production through project planning and project control. Project planning
is concerned with the specification of the components, timing, resources,
and procedures of the project. Project control is concerned with monitoring
the progress of the project, its direction, quality, and resource utilization
as compared with project plans.

Figure 3: An example of a series of contractual arrangements during the life of an information system.
The life of an information system will typically contain several IS-adaptations
regulated by contracts, e.g. one or more change study studies, and one
or more system description, construction, installation, or maintenance
projects. When any such adaptation contract is established, the information
system and the knowledge on the information system are in a certain state,
called the initial state of the adaptation. The desired state of the information
system and the related products which express the knowledge on the information
system at the termination of the contract is called the final state of
the adaptation. Euromethod provides the concepts and guidelines to determine
both initial and final states of information system adaptations in a flexible
way, to better suit each specific situation.

A distinction is made between two levels of customer-supplier relations: the relationship at a contractual level and the relationship at a project level. The main focus of Euromethod is on the contractual level starting with the call for tender, proceeding through the signing of a contract, eventually entering into the actual production of a set of deliverables, and finally ending when the contract is terminated. From this point of view Euromethod is designed to:

A problem situation is expressed using a set of situational factors, and these properties of the problem situation are used to predict the risks and thus determine the appropriate problem solving strategies for their containment or reduction.
In this sense, Euromethod applies a situation driven approach to IS adaptation. It does so through guidelines for:

The types of transactions between a customer and a supplier are modeled as illustrated on Figure 7. Three processes are considered:

The process followed by the customer and the supplier during the production process will consist of transactions in which decisions about the information system and the way it is produced are approved or made. The main decision points have to be approved by the customer or made in co-operation with them, and the sequence of the related transactions is specified in the delivery plan.
Euromethod is providing assistance in planning these decision points
and customer-supplier transactions. It also gives some help in determining
the right products that must be delivered to support a certain decision.
For the customer, the deliverables are more important than the way in which they are produced by the supplier. "What" is more important than "How". Some of these deliverables are stated as the objective of the contract. It is crucial that there is a mutual understanding between the customer and supplier regarding the goal, and the meaning of these deliverables. In addition, other deliverables need to be included to provide the customer with sufficient information on intermediate results, plans, and progress made.

For the supplier, both deliverables and activities are important. Nevertheless, the activities are subordinate to the deliverables because a project is defined through the dynamic contractual relationship with the customer.
The classification of deliverables is based on the distinction between target domain and project domain. The target domain is that part of an organisation for which an IS-adaptation should be performed. The project domain is the temporary organisation, sometimes called project, which has been set up with the goal of adapting an information system of an organisation.
Euromethod includes three types of deliverables as illustrated in Figure
8. Target domain deliverables relate to the information system to be
adapted and they include descriptions as well as operational items of the
information system. The delivery plan contains a description of the approach
to the production process as agreed between the customer and the supplier.
Finally, project domain deliverables relate to the process of production
including more detailed plans, as well as reports on progress and problems.
Plans for future IS-adaptations can also be produced during an IS-adaptation.
Euromethod offers guidelines to bridge between its own concepts, on the one hand, and the concepts of development methods on the other. These guidelines can be used in applications of Euromethod to specific IS-adaptations. In a different context, these guidelines can serve as a framework to achieve some level of conceptual harmonization between different development methods.
