On the use of design patterns in collaborative design processes
2011
Abstract Even if the usefulness of a knowledge repository represented as a collection of design patterns is largely recognized in the literature, little work has been done in investigating and measuring the impact such a collection would have on collaborative design processes involving designers. The paper describes the results of a case study designed to bring some insight into the matter. 18 design workshops were conducted with 18 teams of undergraduate students in Computer Science.
Industrial experience with design patterns
Proceedings of IEEE 18th International Conference on Software Engineering
A design pattern is a particular prose form of recording design information such that designs which have worked well in the past can be applied again in similar situations in the future. The availability of a collection of design patterns can help both the experienced and the novice designer recognize situations in which design reuse could or should occur. We have found that design patterns: 1) provide an eflective "shorthand" for communicating complex concepts effectively between designers, 2) can be used to record and encourage the reuse of "best practices", 3) capture the essential parts of a design in compact form, e.g. for documentation of existing software architectures. Since the patterns community is one that shares information in an open forum and builds on the experiences of others, we chose to submit a joint paper on our industrial experiences with patterns. We focus on the lessons learned in our respective industrial settings as a jirst step towards answering the questions 'patterns sound very promising, but how are they actually used m the industry and what benefits, if any, do they bring in practice ?" We proceed by briefly describing each of our respective experiences with patterns. This is followed by a joint "lessons learned" section and conclusion.
A design science based evaluation framework for patterns
ACM SIGMIS Database, 2010
Patterns were originally developed in the field of architecture as a mechanism for communicating good solutions to recurring classes of problems. Since then, many researchers and practitioners have created patterns to describe effective solutions to problems associated with disparate areas such as virtual project management, human-computer interaction, software development and engineering, and design science research. We believe that the development of patterns is a design science activity in which an artifact (i.e., a pattern) is created to communicate about and improve upon the current state-of-practice. Design science research has two critical components, creation and evaluation of an artifact. While many patterns have been created, few, if any, have been evaluated in this sense. In this paper, we propose a framework to evaluate patterns in any domain and provide examples of how to use the evaluation framework. This process of evaluation could help researchers refine extant patterns and improve the possibility of creating sustainable best practices for a given domain. We believe this evaluation framework begins an important dialogue related to the evaluation of patterns as artifacts of design science research. We draw upon the literature associated with patterns, evaluation of design science research, and research methods to develop this framework for evaluating patterns in a more consistent and rigorous manner.
Design Patterns as First Class Citizens in Software Development
Using design patterns in software development has been studied extensively since its main introduction in 1995. While many types of design patterns have been proposed and implemented, pattern-based development has not been accepted widely in industrial software projects. In this paper, we review various studies of the reasons for this reluctance and summarize an approach which can increase the benefits of design pattern based development over the project lifecycle. The main topic of this paper is the roles design patterns can play in software development. The most widely used role is where the developer becomes well-acquainted with design patterns and uses them casually as coding styles in projects. Another, much less used approach is to try to determine design patterns which best characterize an existing software; which is essentially a classification problem. The motivation for this approach may be to better understand the code structure, to document it and/or to reengineer it. Our approach will use a combination of the two, adding extensive user guidance for pattern selection and implementation. We believe that pattern-based development can become a new paradigm in software development practice where eventually most development may be done with the help of patterns, where the user initially selects an architectural pattern, and places components in it created by selecting design patterns and filling in their application logic, possibly including library components. Our envisioned development framework will contain facilities to discover and recommend patterns, code instrumentation, and other facilities for model-based development. This is a continuation of the trend in programming languages, starting with hardware machine language, to progressively higher levels of languages; analogous to trends in many manufacturing industries.
Design Patterns - education and classification challenge
Proceedings of the 20th Central European Conference on Information and Intelligent Systems
Design patterns have been recognized as a way to simplify and unify applications development process. There are two problems among others that can be identified when talking about design patterns. First there is a problem in education of novices about patterns and training them to fully understand how to find the right pattern for some problem. Second problem is classification and location of patterns that would make it easier to find the right pattern for the right problem and right technology. There are a lot of patterns created almost every day and there are a lot of books that mention some classifications and a number of patterns but there is still a lack of some more practical classification that would enable one to find the right pattern easily. In this paper we give a brief overview of and discussion about problems associated with education of novices. We give a brief view at patterns and the most common classification of patterns and we comment some commonly used technologies in combination with design patterns. We also discuss two mentioned problems along with possible ideas for their resolution.
Lessons learned from using design patterns in industry projects
2011
Design patterns help in the creative act of designing, implementing, and documenting software systems. They have become an important part of the vocabulary of experienced software developers. This article reports about the author's experiences and lessons learned with using and applying design patterns in industry projects.
Proceedings of the 23rd European Conference on Pattern Languages of Programs, 2018
In a straightforward meta-level shift of focus, we use design patterns as a medium and process for capturing insight about the process of design. We survey mainstream design genres, and draw conclusions about how they can help inform the design of intelligent systems.

Design Patterns: Current Challenges, Trends, and Research Directions
2016
Design patterns solve recurring design problems. We can classify the literature on design patterns into two main categories: 1) Pattern Application, i.e., applying design patterns on a design model which is a forward engineering approach, and 2) Pattern Detection and Identification, i.e, extracting applied design patterns from a given source code which is a reverse engineering approach. With the above classification in mind, this report intends to explore the current challenges behind the design patterns and related tools.
