Putting the Parts Together – Concepts, Description Techniques, and Development Process for Componentware Klaus Bergner, Andreas Rausch,Marc Sihling, Alexander Vilbig  bergner  rausch  sihling  vilbig  @in.tum.de Institut fu?r Informatik Technische Universita?t Mu?nchen D-80290 Mu?nchen rmatik.tu-muenchen.de Abstract We outline and clarify the essential concepts of the componentware paradigm. After motivating the role of formal foundations and introducing a number of useful de- scription techniques, we propose a flexible process model for component-based development based on process pat- terns. The presented techniques and concepts serve as building blocks of an overall methodology for component- ware which is the focus of our current work. Keywords: Componentware, Methodology, Description Techniques, Process Model, Pattern 1 Introduction Componentware is concerned with the development of software systems by using components as the es- sential building blocks. It is not a revolutionary ap- proach but incorporates successful concepts from estab- lished paradigms like object-orientation while trying to overcome some of their deficiencies. Proper encapsula- tion of common functionality, for example, and intuitive graphical description techniques like class diagrams are keys to the widespread success of an object-oriented soft- ware development process. However, the increasing size and complexity of modern software systems leads to huge and complicated conglomerations of classes and objects that are hard to manage and understand. Those systems obviously require a more advanced means of structuring, describing and developing them. Componentware is a possible approach to solve to these problems.  This paper originates from the research project A1 – Meth- ods for Component-Based Software Engineering, a part of Bayerischer Forschungsverbund Software-Engineering (FORSOFT), supported by Siemens ZT. An analogy to the building industry illustrates a suc- cessful applicat
