3. Between 1998 and 2001, component sales are predicted to increase from $1.1 billion to $2.4 billion and related services from $2.2 billion to $5.5 billion. Gartner Group Market Research Component Industry Services Sales 2001 $2.4 billion $5.5 billion Copyright (c) 1998 by Extended Intelligence, Inc

4. Components Software parts that - –Provide a common function or feature –Have well-defined interfaces –Hide implementation details –Have ability to interoperate with other components –Fit into an architecture –Have potential to be reused in multiple software products and systems Copyright (c) 1998 by Extended Intelligence, Inc

5. Component-Based Development Architecture-driven construction approach whereby software products and systems are assembled from components Architecture is a generic structure that provides a framework for assembling the components Copyright (c) 1998 by Extended Intelligence, Inc

6. Benefits of Components Deploy mission-critical systems more quickly; gain competitive advantage Simplify large-scale development Make system more adaptable; easier to change Improve software quality Increase software productivity; lower costs Copyright (c) 1998 by Extended Intelligence, Inc

7. Power of Reuse Faster, better, cheaper, without compromise Reuse is the only technology that allows a company to simultaneously address software cost, time-to-market, flexibility and quality. - Gartner Group Reuse Report, 1995 Copyright (c) 1998 by Extended Intelligence, Inc

8. Reuse Opportunities 60 - 70 % of a software product’s functionality is common Copyright (c) 1998 by Extended Intelligence, Inc

9. Components Need Standards Interface Standards –Interconnecting components written in different languages supplied by different sources Process Standards –Specifying the types of components used by the component- based development and the activities for performing component identification, construction, selection & assembly Copyright (c) 1998 by Extended Intelligence, Inc

10. UML Unified Modeling Language OMG nonproprietary, open standard Common modeling language for building distributed objects Standardized notation and semantics for describing software analysis and design models (e.g., Use Case, Class, Activity) Copyright (c) 1998 by Extended Intelligence, Inc

17. IEEE Reuse Process Standard Purpose –Establish a framework for practicing reuse within the software life cycle model –Define the minimum set of processes, activities and tasks that are required to practice reuse –Promote and control the practice of reuse –Define reuse terminology Copyright (c) 1998 by Extended Intelligence, Inc

18. IEEE Std. 1517 IEEE Std. 1517 - Standard for Information Technology - Software Life Cycle Processes - Reuse Processes Requirements specification for practicing systematic reuse on an enterprise-wide basis Guide for using the best software reuse practices Copyright (c) 1998 by Extended Intelligence, Inc

19. IEEE Std. 1517- Reuse Process May be used to - –Acquire, supply, develop and maintain reusable components –Acquire, supply, develop, operate and maintain software built with reusable components –Manage and improve an organization’s software life cycle process w.r.t. reuse Copyright (c) 1998 by Extended Intelligence, Inc

20. IEEE Std. 1517 - Reuse Process May be used to - –Establish software management and engineering environments based on reuse –Facilitate the use of reusable components to develop software products and systems –Facilitate the development of reusable components –Foster an understanding of reuse among parties involved in life cycle process Copyright (c) 1998 by Extended Intelligence, Inc

21. ISO/IEC 12207 Standard for Information Technology - Software Life Cycle Processes Copyright (c) 1998 by Extended Intelligence, Inc

22. ISO/IEC 12207 Purpose –Establish a common framework for software life cycle processes –Describe architecture of software life cycle processes, but not details of how to perform process activities and tasks –Contain processes that are applied during the acquisition, supply, development, operation and maintenance of software products Copyright (c) 1998 by Extended Intelligence, Inc
