CRC cards are unconventional method for identifying and describing classes, behavior and its responsibilities and collaborators of class. Representation of three categories of class, responsibilities and collaborators can give proper image of scenario. These cards are effective method for analyzing scenarios. With all positive features of CRC cards, of weaknesses of these cards are failure to s...

Class Responsibility Collaborator (CRC) Cards can be used in developing Object-Oriented models. They provide a simple and an easy to use way to explore objects in the development of a system. However, different problems might arise while adopting current CRC-Cards in identifying the system objects. In this paper, we discuss the main problems with current CRC-Cards. As a solution, we propose a n...

CRC-cards have been adopted by many educators to teach early design in their object-oriented programming courses. In this paper we discuss our experiences using the CRC-card approach in upper secondary school and undergraduate programming courses. Although our experiences are generally positive, we have noticed many problems and issues that have largely gone unnoticed in the literature. It is t...

The Class Responsibility Collaborator (CRC) cards are index cards that are utilized for mapping candidates classes in predefined design scenarios; e.g. Use Case Scenarios. The objective of CRC cards is to facilitate the design process while insuring an active participation of involved designers. This paper represents the first attempt towards a CRC card pattern language representation via stabl...

UNLABELLED Class-responsibility-collaboration (CRC) cards have been used extensively in the software industry for defining complex object-oriented software requirements. We have adapted this tool to capture information about biological components, collaborators and responsibilities within these collaborations, which is not captured by current annotation tools. CRC cards should provide a common ...

BACKGROUND Colorectal cancer (CRC) screening rates are low in many areas and cost-effective interventions to promote CRC screening are needed. Recently in a randomized controlled trial, a mailed educational reminder increased CRC screening rates by 16.2% among U.S. Veterans. The aim of our study was to assess the costs and cost-effectiveness of a mailed educational reminder on fecal occult bloo...

Introducing object-oriented problem solving and programming has shown to be more difficult than expected. The way we "used to do" do not work as well as it did with the imperative approach. In an attempt to compare how people conceive the idea of objects and object oriented design/ problem-solving subject to the way it is taught, we conducted a study during Summer-University 2001. The aim was t...

This paper presents a technique that uses role-play and index cards to review use cases and to assist in making use case development more accessible and better guided. The technique is based on the established CRC card technique used for object-oriented design. In our technique, essential use cases are recorded on index cards, and role-play is used for development and review. The paper presents...

Techniques for object-oriented software development range from well established (such CRC cards, scenario analysis and object/class modeling) to newer developments. In this tutorial will be included some of the more recent developments within OPEN (Henderson-Sellers and Graham, 1997). These are likely to be selected from, for example, distributed computing, roles, rule modeling, project managem...

In building process models based on objects, we identify a gap between object capabilities and the process world. To overcome this problem, a level of abstraction , role, above the object level, similar to pattern structure, has been deened. We have represented roles in diierent levels of abstraction containing CRC cards, for-malised CRC (CRC plus path expressions), Petri nets, and encapsulated...
