MacA&D is a comprehensive tool for system modeling and simulation, requirements management, structured analysis and design, object-oriented modeling with UML and data modeling of information systems. It has diagram editors for process models, data models, class models, state models, object models, structure models and task models. Each model shows a different view of the software system integrated through a global data dictionary. Dictionary and model information can be used to generate code for several languages including C++, Java, Delphi, Objective-C and SQL. Dynamic systems can be modeled, parameterized, simulated and charted. The tool provides requirements specification and traceability, design verification reports and text import/export features. The integrated report generator includes dozens of standard reports plus a scriptable environment for creating custom reports. The Site License edition supports multi-user team dictionary and requirement documents making it well suited for team development.

MacTranslator is used with MacA&D, QuickCRC or QuickUML to generate class models or CRC cards from object-oriented software written in C++, Objective-C, Java or Delphi. Code written in C, Pascal, procedural Basic or Fortran generates structure charts. Large software systems are partitioned into multiple diagrams with objects linked to related source code. Detailed information can be extracted from the code including data types, parameter lists and descriptive comments. An dialog steps the user through the reengineering process. Rich data models can be generated from SQL.

ObjcUnit is a unit testing framework for Objective-C on Mac OS X. Its design was copied from JUnit, written by Erich Gamma and Kent Beck, and then adapted somewhat for Objective-C.

OCUnit is a testing framework for Objective C in the Mac OS X, Mac OS X Server, GNUSTEP, YellowBox/Cocoa and WebObjects/Objective C environments.

PyInstaller is a program that converts (packages) Python programs into stand-alone executables, under Windows, Linux, Mac OS X, Solaris and AIX. Its main advantages over similar tools are that PyInstaller works with any version of Python since 2.2, it builds smaller executables thanks to transparent compression, it is fully multi-platform, and use the OS support to load the dynamic libraries, thus ensuring full compatibility.

QuickCRC is a tool for responsibility driven design of object-oriented software using CRC cards. CRC cards are used to discover and document classes, responsibilities, attributes and collaborations between classes. Design scenarios can be identified and simulated. Complex designs can be partitioned into multiple diagrams with easy navigation through a contents view. The inheritance graph automatically shows the class structure of the evolving design. The user can assign the attribute access of each card responsibility and the tool presents an attribute access graph.

QuickHelp is a help authoring and deployment tool. QuickHelp consists of a Builder edition for creating, formatting and linking help topics and a Viewer edition for deploying them to end-users. The help information resides in an XML file distributed with the QuickHelp Viewer. For the end-user, QuickHelp supports a table of contents, an index with automatic search field, word searches across topics, color highlighted topic text with hypertext links, formatted images, tables, actions and context sensitive help from applications. For the developer, QuickHelp provides a highly productive editing environment to create, verify and maintain application help that can be deployed to Windows 95, 98, NT, 2000, XP, Mac OS 9, Mac OS X and Linux.

The QuickLicense system makes it easy to protect and manage software licenses for any Windows or Macintosh application. The QuickLicense application is used to configure a licensing strategy that is stored in a highly encrypted Ticket file. That file and the royalty-free QuickLicense runtime software are included with an application written in any programming language. With QuickLicense, it's easy to create time or execution limited Trial editions, control application features, determine which machines or user's can run the software or create time-leased applications. QuickLicense can handle online activations and collect customer data. Customer data can be searched, organized, exported or imported to a spreadsheet or database and used to manage the evaluation, sales and support process.

QuickUML is a software design tool that tightly integrates a core set of UML models with code generation for several languages. An entire project is presented through a tabbed window that includes use cases, class models, object models, dictionary and code and saved as an XML file. Use cases document user interactions with the system and link to models, code, foreign files or other use cases. Class models may contain classes, interfaces, components, packages and other objects. Sequence diagrams illustrate how objects interact with emphasis on the order in which things occur. QuickUML contains advanced features for multiple language projects, design namespaces, UML stereotype extensions, flexible color support, custom detail fields and automated generation of class models from the dictionary. An integrated code manager enables the designer to navigate through code files linked to use cases and diagram objects.
