Extended Enterprise Modeling Language (EEML) is commonly used for business process modeling across a number of layers. EEML is intended to be a simple language, which makes it easy to update models. In addition to capturing the various tasks(can consist of several sub-tasks) and their interdependencies, models show which roles perform each task, and the tools, services and information they apply.
EEML is the result of several years of research. Originally developed in [1] to support development and use of interactive models.
EEML Topics
Modeling domains
The modeling language currently includes four modeling domains, in addition to general modeling mechanisms and primitives provided in Metis (modelling)
- Process modeling
- Process logic is modeled through nested structures of tasks and decision points.
- Resource modeling
- Roles are used to connect resources of various kinds (people, organisations, information, and tools) to the tasks.
- Goal modeling
- The modeling of goal and rule structures in an organisation
- See Goal Modelling,
- Data modeling (UML Class Diagram)
EEML Layers
EEML has four layers of interest
- Generic Task Type
- This layer identifies the constituent tasks of generic, repetitive processes and the logical dependencies between these tasks.
- Specific Task Type
- In this layer process models are expanded, concretised, decomposed and specialised to facilitate business solutions.
- Manage Task Instances
- Here, more detailed decisions are taken regarding work in the actual work environment with its organisational, information, and tool resources.
- Perform Task Instances
- This layer covers the actual execution of tasks.
Goal Modelling
Goal Modelling is one of the four EEML modeling domains age. A goal expresses the wanted (or unwanted) state of affairs (either current or future) in a certain context. Example of the goal model is depicted below. It shows goals and relationships between them. It is possible to model advanced goal-relationships in EEML by using goal connectors. A goal connector is used when one need to link several goals.

Connecting relationships
-
Goal modeling and process modeling
In goal modeling to fulfil Goal1, one must achieve to other goals: both Goal2 and Goal3 (goal-connector with “and” as the logical relation going out). If Goal2 and Goal3 are two different ways of achieving Goal1, then it should be “xor” logical relationship. It can be an opposite situation when both Goal2 and Goal3 need to be fulfilled and to achieve them one must fulfil Goal1. In this case Goal2 and Goal3 are linked to goal connector and this goal connector has a link to Goal1 with ”and”-logical relationship.
The table indicate different types of connecting relationships in EEML goal modeling. Goal model can also be interlinked with a process model.
