Ectropic Design supports object-oriented analysis (OOA), object-oriented design (OOD), and object-oriented programming (OOP) in Squeak. Our goal is to bring more order to projects suffering from entropy - the tendancy for code and design to become more disordered as it matures. We believe that design critics, collaboration, code generation, code import, and tightly integrated design and coding concepts allow users to impose more order on a new or existing project. OOA Tools: CRC Cards with a diagram layout, Scenarios, and a Goal Tree all connected by common responsibilities. OOD Tools: Simplified UML class diagram. OOP Tools: Code Generation, and Code Import.
