1. 1 Communication Virtual Machine Feature Analysis & Policy Definitions Paola Boettner Mansi Gupta PhD Students Andrew Allen & Yali Wu

2. 2 Motivation Provide users with a Communication Paradigm takes into consideration: Rich functionality User priorities User preferences CVM is the solution

3. 3 What is CVM? CVM is a new paradigm for developing collaborative communication applications. [1]

4. 4 Project Description Explore communication frameworks and analyze user needs to form policy structures for CVM Tasks: 1) Literature Review and Feature Analysis 2) Policy Definitions

5. 5 Literature Review Identifying various communication frameworks Exploring each framework: Core Features Additional Features API Scan developer websites, follow links, experiment with features Compile findings and analyze them using domain analysis

6. 6 Domain Analysis [12] Domain analysis is the process of analyzing related software systems in a domain to find their common and variable parts. It is a key method for realizing systematic software reuse. Several methods for domain analysis have been proposed, producing models such as feature tables and feature diagrams.

7. 7 Feature Analysis [2] The process of identifying, collecting, organizing and representing information in a domain based on the study of existing systems and development histories. Take into account the ways in which the systems are alike (core features) and how they differ (additional features) in order to allow successful software re-use.

8. 8 Importance of Feature Analysis Provides a generic description of the requirements of systems. Provides a basis for understanding the problem space addressed by software in the domain. Proposes a set of approaches for the implementation of new systems.

16. 16 Next Steps A policy is a set of considerations designed to guide decisions on courses of action. They are rules that define the choices in the behavior of a system. Identify policy structures: Use comparative study of features Identify user needs by creating common scenarios Create a GUI for users to create their policies
