VisualFSM Models

VisualFSM is a Model driven Functional Size Analysis and Measurement Tool. This approach means that although much work is done in the initial stages, the final process of measurement is largely automated. The accuracy of the measure is primarily dependent on the accuracy of the models from which it is derived.

There are 4 main models: the Software Model,the Function Model, the Analysis Model, and the Measurement Model

Software Model

The Software Model (click on picture to see the VisualFSM Demo ) describes the software to be analysed and measured It comprises:

A description of the services provided to its users, the domain to which it belongs and the sub domains.

A viewpoint of the Software which represent the view of the software that is of interest to the Stakeholders and their Concerns. The main component of this model is the Function Model.

Function Model

The Function Model describes the functions the Software provides to it users.

It is in the form of a Hierarchical Tree structure where Functions can be grouped together so forming the Function Breakdown

The Function Model is the primary input to the Measurement Model.

Analysis Model

The Analysis Model comprises the requirements of the measurement.

It identifies the Stakeholders and their concerns and therefore the use to which the measurement will be put

It defines the scope of the measurement in terms of the Functions that are included, and those that are excluded

Finally it states the method or methods to be used

Measurement Model

VisualFSM supports four Functional Size Measurement Methods.

Each method has its own Measurement Model and VisualFSM provides separate analysis screens which the analyst uses to construct the model and subsequently measure the size

The model assigns a size to each function in the Function Model.
