CSE 300: Software Reliability Engineering Topics covered: Project overview

Objectives  Introduce the state-of-the-art in reliability engineering.  Cultivate the ability to understand and critique research papers.  Implement and adapt reliability analysis techniques presented in research papers.  Develop communication skills and ability to work in a team  Enhance presentation skills

Project components  Each project will be conducted by a team of two students  Select your partner and let me know.  Each project will be based on one research paper  Related to (or may extend) the topics covered in class.  Three components:  Presentation  Implementation  Report

Presentation  Each group will be expected to present the chosen paper to the class.  Each presentation will be allotted 15 minutes.  Presentation should address the following:  Motivation  Problem description  Approach  Advantages  Disadvantages  What would be your approach?

Implementation  Implement a key technique:  More than one technique presented in some papers.  Identify one technique and implement it.  Language/package of your choice.  Reproduce at least some of the results

Report  Consist of three parts:  Part I: Summary & Critique  Overview of the paper.  Advantages & disadvantages  Approach you would adopt  Part II: Implementation  Decisions about package/language chosen  Problems encountered  Results  Part III: Division of work  How did you divide the work  Comments on your experience in working as a team.
