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.

Popular, widely used OO method, to help during the analysis- and design phases of an object-oriented system using the OO paradigm. Predecessor to the Rational Unified Process: RUP.

Companies or consultants working mainly to develop and implement object-oriented methodologies.

Sites which express views which are critical of Object-Oriented Programming and/or Object-Oriented Design.

Object-oriented Process, Environment and Notation (OPEN) supersedes the MOSES methodology. It is a 3d generation, fully object-oriented software development methodology encapsulating issues of business, quality, modeling, and reuse. It is a Web-enabled, easily customizable system and software development process framework that includes numerous reusable components and associated standards, procedures, templates, checklists, and examples. It is public domain.

Organization, research groups, and universities focused on the development of object-oriented methodologies and related tools.
