  1. Reuse Tapestry Richard Conn Software Process Engineer LMAS, C-130J Software IPT Lead, Reuse Tapestry Presented at Lockheed Martin COTS/Reuse 2000 Symposium 25 January 2000 Revision 1

  2. Topics What Is Reuse Tapestry? Players – Old and New Effective Reuse Ties to Lockheed Martin Aeronautical Systems (LMAS) Reuse Tapestry Reuse Tapestry is a set of activities oriented to the study and demonstration of both technical and non-technical issues associated with effective Software Reuse, including the creation of product lines through the use of domain-specific kits. It applies and demonstrates many of the best practices. It has evolved over the last 20 years into a global collaboration. Topics Software Courseware Guideware and Documentation

  9. From Practices of High Maturity Organizations: The 1999 Survey by Mark Paulk, Dennis Goldenson, and David White of the SEI (slide 37) - “High maturity organizations typically are doing systematic reuse with domain engineering and/or product lines/families.” 40 CMM Level 4 organizations 21 CMM Level 5 organizations 32 respondents to the survey Survey conducted in November 1999 Effective software reuse on a large scale has become common in industry; some examples: Standard Cells used by Integrated Circuit manufacturers Microsoft Developer’s Network Library (on DVD), subscription available Microsoft Academic Cooperative with 350 college and university members Microsoft ActiveX Control industry, with over 400 vendors Sun Java and Java Beans libraries, subscription available Effective Reuse

  10. Effective ReuseIntegrated Circuits • Table Lookup Chip 3 • Perform table lookups using special-purpose dual-CPU chip rather than conventional software for hard real-time applications • Speed improvement – 100x • Frees conventional software for modeling and built-in test • DARPA sponsorship in 1990

  11. Effective ReuseEconomics of Reuse • Quickly Finding Useful Material • Consortium for Educational Technology in University Systems (CETUS) • Discerning - better than a traditional search engine

  12. Effective ReuseCourse Technology • Course Technology • Courseware • Teaching Tools • Instructor Resource Kits (Domain-Specific Kits) • Online Companions

  13. Effective ReuseMSDN and MSDN Library • Microsoft Developer’s Network (MSDN) • Large numbers of reusable classes, including classes providing functionality at high levels of abstraction • Large numbers of software development tools • Updated quarterly via subscription

  14. Effective ReuseASE Library • ASE Library • Software • Ada, Java, C, C++, VHDL, Visual Basic • Components, Tools • Courseware • More than 100 courses • Languages, Software Engineering (incl. Reuse) • Guideware/Documentation • SEI, Crosstalk, WISR • 1000’s of documents
