2. Reuse in Software Engineering Group Agenda  Motivation  A Brief survey on Software reuse  RiSE Project: Towards a Robust Framework for Software reuse  Context  The Repository system  RiSE’s goals  The Future  The Present  Concluding remarks and Future works

3. 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

4. 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?

5. 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  www.cin.ufpe.br/~rise  Goal: To Guide organizations in the adoption of a reuse program

6. 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”

7. 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

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

9. Reuse in Software Engineering Group RiSE Project: Towards a Robust Framework for Software Reuse  RiSE Group  2 PhDs  12 students (4 PhD, 5 MSc, 3 BSc)  Budget: $600.000 (2 years, start: Jan 2005)  Customer: Brazilian Government  Partnership  Brazilian Software Factory  www.cin.ufpe.br/ ~rise

10. Reuse in Software Engineering Group RiSE Project  Fundamental step to introduce reuse in companies  Technical and non-technical aspects

11. Reuse in Software Engineering Group RiSE Project: The Repository System  Core of the project  Hard task to research and development  Main features  Storage  Search  Management  Distribution  Load balance ….

12. Reuse in Software Engineering Group But, What are the RiSE’s goals?

13. Reuse in Software Engineering Group This story starts in 2025

14. Reuse in Software Engineering Group …and Currently 2005

15. Reuse in Software Engineering Group RiSE {Initial} Solution  Open source  Java Projects  Plug-in Eclipse

16. Reuse in Software Engineering Group Concluding Remarks and Future works  Robust framework for software reuse  Technical and non-technical aspects  Based on:  Studies related to state-of-the-art  Real problems  Academia + Industry  Future works  Reuse process {metrics, cost models, reengineering..}  Component certification process  Repository system  Tools
