This category is on BON, Business Object Notation, a modelling language to model business processes in object-oriented (OO) software development, a method and graphic notation for high level OO analysis and design. OO methods have unusual potential for code reuse and seamlessness. BON allows seamless analysis, design, and implementation for developing software. BON's creator was Jean-Marc Nerson, who completed it with Kim Waldén, Enea Data, Stockholm. The best known BON implementation is in the Eiffel programming language, but it works with any OO system.
