Reuse in Software Engineering Group Agenda  Motivation  A Brief survey on Software reuse  RiSE Project: Towards a Robust Framework for Software reuse  The reuse processes  The Software reuse environment  The Component certification process  The Repository System  Concluding remarks and Future works

Reuse in Software Engineering Group Motivation  Software reuse is a critical aspect for companies interested in the improvements  Quality  Productivity  Costs reduction But, How to aid companies to perform it?  Literature  Domain Engineering  Component-Based Development  Software Product Lines

Reuse in Software Engineering Group Motivation (cont.)  Experiences  Previous experiences  Success and Failure models  Myths and Inhibitors How to apply it outside its original context?

Reuse in Software Engineering Group Motivation (cont.)  Research approach:  RiSE Project: A robust framework for reuse based on:  Partneship with Industry  Software reuse surveys {academia + industry}  Reuse, Processes, Repository   Goal: To Guide organizations in the adoption of a reuse program

Reuse in Software Engineering Group A Brief Survey on Reuse  The beginning:  NATO Software Engineering Conference (1968)  Doug Mcllroy said:  “the software industry is weakly founded and one aspect of this weakness is the absence of a software component sub-industry”  After Mcllroy: research/evolution {DE, CBD, SPL}  Doug Mcllroy also again:  “To develop a useful inventory, money and talent will be need. Thus, the whole project is an improbable one for university research”

Reuse in Software Engineering Group Sucess Factors  Informal research  Frakes & Isoda (1995)  Management, Measurement, Legal issues, Economics, Design for reuse, Libraries  Glass (1998)  Lack of components  Empirical research  Rine (1998)  SPL, DE, CBD, Tools...  Morisio et. al (2002)  Reuse processes, Modify non-reuse processes, Human factors

Reuse in Software Engineering Group Sucess Factors (cont.)  Empirical research  Rothenberger et. al (2003)  Planning  Formalized processes  Management support  Project similarity  Common architecture
