have to be documented possibly with simple tools and presented to the intended
target audience, e.g. on the corporate intranet.
Maintain and share knowledge about the business. The tools supporting this
intention should be have web-interface and should preferably offer the possibilities
to annotating the models with text including collecting user feedback and comments.
Use EM as a problem solving tool. Since after the modeling session the models
the models will only serve as meeting minutes, the “plastic wall” should be used for
modeling and simple tools for producing the meeting minutes.

5.6 Model Quality Requirements

Quality of enterprise models produced in different projects differs depending on the
project objectives and the purpose of models. According to [ 21] the main criteria
for successful application of EKD are that (1) the quality of the produced models
is high, (2) the result is useful and actually used after the modeling activity is com-
pleted, and (3) the involved stakeholders are satisfied with the process and the result.
[ 14] suggest that the following quality criteria adopted from [18] are applicable to
enterprise models:

• Completeness - the degree to which all relevant facts are included in the

enterprise model.

• Correctness - refers to how well the enterprise model conforms to the rules of

the modeling technique.

• Flexibility - is defined as the ease with which the enterprise model can cope with

changes in the modeling domain.

• Integration - refers to the degree of consistency between the different sub-models

that constitute the enterprise model.

• Simplicity - refers to the degree of minimal use of modeling constructs for

presenting knowledge in the enterprise model.

•

Understandability - is defined as the ease with which the concepts and structures
in the enterprise model can be understood by the stakeholders.

• Usability - is defined as the ease with which the enterprise model can be used for

its intended purpose.

Develop vision and strategies. The main quality requirements are understand-
ability, correctness, simplicity, and flexibility, which are the key factors supporting
efficient communication among stakeholders.
Design/re-design the business. The enterprise model presents an organiza-
tional design and hence broad range of the quality requirements - completeness,
correctness, flexibility, integration, understandability, and usability.
Develop IS. The main quality requirements are completeness, correctness, flex-
ibility, integration, and usability. Referring the choice of the modeling language in
this case the understandability for a broad range of stakeholders might be reduced
