Moving architectural description from under the Technology lamppost
Information and Software Technology, 2007Co-Authors: Nenad Medvidovic, Eric M. Dashofy, Richard N. TaylorAbstract:In 2000, we published an extensive study of existing software architecture description languages (ADLs), which has served as a useful reference to software architecture researchers and practitioners. Since then, circumstances have changed. The Unified Modeling Language (UML) has gained popularity and wide adoption, and many of the ADLs we studied have been pushed into obscurity. We argue that this progression can be attributed to early ADLs' nearly exclusive focus on technological aspects of architecture, ignoring application Domain and business contexts within which software systems and development organizations exist. These three concerns - Technology, Domain, and business - constitute three ''lampposts'' needed to appropriately ''illuminate'' software architecture and architectural description.

moving architectural description from under the Technology lamppost
Software Engineering and Advanced Applications, 2006Co-Authors: Nenad MedvidovicAbstract:Software architecture description languages (ADLs) were a particularly active research area in the 1990s. In 2000, the author co-authored an extensive study of existing ADLs, which has served as a useful reference to software architecture researchers and practitioners. However, the field of software architecture and our understanding of it have undergone a number of changes in the past several years. In particular, the Unified Modeling Language (UML) has gained a lot of popularity and wide adoption, and as a result many of the ADLs the author had studied have been pushed into obscurity. In this paper, the author argues that the main reason behind this is that the early ADLs focused almost exclusively on the technological aspects of architecture, and mostly ignored the application Domain and business contexts within which software systems, and development organizations, exist. Together, these three concerns - Technology, Domain, and business -constitute the three "lampposts " needed to appropriately "illuminate" software architecture and architectural description. The author use this new framework to evaluate both the languages from my original study, as well as several more recent ADLs (including UML 2.0)

technological improvement rate estimates for all technologies use of patent data and an extended Domain description
arXiv: General Economics, 2020Co-Authors: Giorgio Triulzi, Anuraag Singh, Christopher L MageeAbstract:In this work, we attempt to provide a comprehensive granular account of the pace of technological change. More specifically, we survey estimated yearly performance improvement rates for nearly all definable technologies for the first time. We do this by creating a correspondence of all patents within the US patent system to a set of Technology Domains. A Technology Domain is a body of patented inventions achieving the same technological function using the same knowledge and scientific principles. We obtain a set of 1757 Domains using an extension of the previously defined classification overlap method (COM). These Domains contain 97.14% of all patents within the entire US patent system. From the identified patent sets, we calculated the average centrality of the patents in each Domain to estimate their improvement rates, following a methodology tested in prior work. The estimated improvement rates vary from a low of 1.9% per year for the Mechanical Skin treatment - Hair Removal and wrinkles Domain to a high of 228.8% per year for the Network management - client-server applications Domain. We developed a one-line descriptor identifying the technological function achieved and the underlying knowledge base for the largest 50, fastest 20 as well as slowest 20 of these Domains, which cover more than forty percent of the patent system. In general, the rates of improvement were not a strong function of the patent set size and the fastest improving Domains are predominantly software-based. We make available an online system that allows for automated searching for Domains and improvement rates corresponding to any Technology of interest to researchers, strategists and policy formulators.

Overlay Technology space map for analyzing design knowledge base of a Technology Domain: the case of hybrid electric vehicles
Research in Engineering Design, 2019Co-Authors: Binyang Song, Giorgio Triulzi, Jeffrey Alstott, Bowen Yan, Jianxi LuoAbstract:A tangible understanding of the latent design knowledge base of a Technology Domain, i.e., the set of technologies and related design knowledge used to solve the specific problems of a Domain, and how it evolves, can guide engineering design efforts in that Domain. However, methods for extracting, analyzing and understanding the structure and evolutionary trajectories of a Domain’s accumulated design knowledge base are still underdeveloped. This study introduces a network-based methodology for visualizing and analyzing the structure and expansion trajectories of the design knowledge base of a given Technology Domain. The methodology is centered on overlaying the total Technology space, represented as a network of all known technologies based on patent data, with the specific knowledge positions and estimated expansion paths of a specific Domain as a subgraph of the total network. We demonstrate the methodology via a case study of hybrid electric vehicles. The methodology may help designers understand the Technology evolution trajectories of their Domain and suggest next design opportunities or directions.

overlay patent network to analyze the design space of a Technology Domain the case of hybrid electrical vehicles
DS 84: Proceedings of the DESIGN 2016 14th International Design Conference, 2016Co-Authors: Binyang Song, Giorgio Triulzi, Jeffrey Alstott, B Yan, J LuoAbstract:Technology Domains are often made of various interactive technologies, which makes Technology forecasting difficult. We introduce a method to visualize, analyze and predict the evolution of a Technology Domain, which is to overlay the design space of a Technology Domain and its evolution paths on the total Technology space. In this way, the structure of the design space of a Domain and its evolution paths can be identified and analyzed. One can also analyze the nearby neighborhood of the current positions of a Domain on the total map, to explore next innovation and expansion opportunties.
