Summary of feature

VisualFSM-RT module is an extension available for all versions of VisualFSM that adds feature to enable realtime exchange and collaboration in building and analysing VisualFSM models for a variety of purposes.

It is a subscription service.


When a subscription has been purchased, access to the VisualFSM Real Server is authorized for the period of the subscription. Subscriptions are monthly and recurring payment is possible.

VisualFSM-RT Functions

VisualFSM-RT Server manages connections between users then receives and sends message beween them.


The messages are encoded and optionaly encrypted ; no messages are stored on the server, it is simply a broker.

Realtime Synchronization

Users can synchronize projects on each machine then build and update them in realtime.

Realtime Collaboration

VisualFSM-RT allows realtime collaboration between users subscribed to the service over the Internet.

Realtime Chat

VisualFSM-RT allows ruser to send and receive instant messages.

RT Module Features


VisualFSM represents a software application or system and the size analysis as a series of formal models. VisualFSM-RT permits the exchange of any or all of these models in realtime and so synchronizes the models of each user.

Models are exchanged directly between users automatically

The Models that can be exchanged are:

Supporting Models: Architecture Templates and fsmPatterns©.

Generic Models: Software Model. Architecture Model. FUR Model, Function Model, Data Model. User Model and Context Model.

Analysis Models: Analysis Requirements Model. and Analysis Scope Model

Method Models (where applicable): Measurement Model, Function Model/Transaction Model, Data Model and User Model.


Once synchronized users can collaborate to build and modify models, define analyses purpose and scope, and perform measurement in any of the supported methods. The models are automatically synchronized in realtime.

This is performed through automatic exchanges of commands and messages via the VisualFSM-RT server.


If direct oral communication is not possible or needed the Chat function allows users to exchange instant messages.

Long messages are exchanged using the RT-Controller Chat panel:

Short messages are visible at all times in the Explorer RT-Mini panel

The features of the VisualFSM-RT Module can be exploited in a number of ways:

Exchange of Ideas.

One of the key objectives of the Community Edition is to enable the FSM community to exchange ideas on a one-to-one basis and so promote the use of Functional size Measurement. The Professional Version adds the one-to-many facility.

Training and Support

The Community and Personal Editions allow one-to-one communication, opening up the possibility of limited training and support.

Remote Development Teams

The Professional and Team Versions provide for one-to-many connections between leaders and users. This allow users to conduct development virtual meeting with remote members or to deliver remote training and workshops.

Agile Development

The Agile module of the Team Version permits the allocation and management of work to be performed by team members in iteration and monitor progress automatically; Function Burn-down and Earned Value charts are updated in realtime.

These and other exploitation possibilities will be described in detail as they become available.
