              PANEL: DESIGN METHODOLOGY FOR OBJECT-ORIENTED PROGRAMMING1
             
                   Abstract: 
                    
                   This panel is aimed at software developers who use object-oriented programming 
                   techniques.  Some developers opt for object-oriented programming in search of enhanced 
                   customizability, extensibility, and reusability of their software.  Others opt for it because of 
                   its perceived utility for modeling and simulation, for exploratory programming, or for user 
                   interface development. 
                    
                   Whatever the reason, the prospective object-oriented programmer is faced with a 
                   programming style that differs significantly from the procedural style in which most 
                   programmers have been raised.  Along with the new style, a new set of design decisions 
                   must be made---and the programmer has little intuition for how to make them.  For 
                   example, the decisions include: 
                     ●  What object-oriented language is appropriate for the application? … how to select 
                         from the available languages according to object-oriented features (e.g., multiple 
                         inheritance), runtime efficiency, and development environment. 
                     ●  What's an object? … how to select a level of granularity appropriate to the application. 
                     ●  What is the right set of classes and how do the classes go together? … many 
                         different hierarchical decompositions can be made, according to a variety of inter-
                         object relationships, like taxonomic [is-a or subclass], part/whole, or other application-
                         specific relationships. 
                     ●  What is an appropriate set of generic methods and in which classes should these 
                         methods be placed? … in order to achieve best use of inheritance, to maximize 
                         clarity, or to maximize reuse. 
                     ●  What is the impact of the development environment on the design of object-oriented 
                         programs? … would Smalltalk programs be different if written in a text-only 
                         environment. 
                     ●  Are development methodologies devised for procedural languages (e.g., functional or 
                         structural decomposition, stepwise refinement, rapid prototyping) appropriate for 
                         object-oriented languages?} … and what to do if and when they are not. 
                     ●  Is Fred Brooks' Mythical Man-Month thesis relevant to object-oriented programming 
                         projects? 
                   The panelists represent a number of different communities experienced in object-oriented 
                   programming, including software engineering, simulation, and artificial intelligence. 
                    
                   Each panelist will present a very brief position paper on design methodology appropriate to 
                   programming in an object-oriented style. The panelists, together with the audience, will 
                   then discuss and debate the issues. The focus will be on practical issues involved in the 
                   use of object-oriented techniques, as opposed to theoretical issues involved in the design 
                   of object-oriented languages.
