Leonard Joel (Len) Bass (born c.1943) is an American software engineer, Emeritus professor and former researcher at the Software Engineering Institute (SEI), particularly known for his contributions on software architecture in practice. [1] [2]
Bass received his Ph.D. degree in Computer Science from Purdue University in 1970 under the supervision of Paul Ruel Young with the thesis, entitled "Hierarchies based on computational complexity and irregularities of class determining measured sets." [3]
Bass was appointed Professor of Computer Science at the University of Rhode Island in 1970.[ citation needed ] In 1986, he moved to the Software Engineering Institute at Carnegie Mellon University, where he started as head of the user-interface software group, and later focused on the analysis of software architectures. Since 2011, he has been Senior Principal Researcher at NICTA (National ICT Australia). [4]
Len Bass was awarded the Software Development Magazine's Jolt Productivity Award twice in 1999 and 2003. [5]

The Capability Maturity Model (CMM) is a development model created in 1986 after a study of data collected from organizations that contracted with the U.S. Department of Defense, who funded the research. The term "maturity" relates to the degree of formality and optimization of processes, from ad hoc practices, to formally defined steps, to managed result metrics, to active optimization of the processes.
Software engineering is an engineering-based approach to software development. A software engineer is a person who applies the engineering design process to design, develop, test, maintain, and evaluate computer software. The term programmer is sometimes used as a synonym, but may emphasize software implementation over design and can also lack connotations of engineering education or skills.
Software Engineering Institute (SEI) is a federally funded research and development center in Pittsburgh, Pennsylvania, United States. Founded in 1984, the institute is now sponsored by the United States Department of Defense and the Office of the Under Secretary of Defense for Research and Engineering, and administrated by Carnegie Mellon University. The activities of the institute cover cybersecurity, software assurance, software engineering and acquisition, and component capabilities critical to the United States Department of Defense.
Carnegie Mellon University (CMU) is a private research university in Pittsburgh, Pennsylvania. The institution was originally established in 1900 by Andrew Carnegie as the Carnegie Technical Schools. In 1912, it became the Carnegie Institute of Technology and began granting four-year degrees. In 1967, it became the current-day Carnegie Mellon University through its merger with the Mellon Institute of Industrial Research, founded in 1913 by Andrew Mellon and Richard B. Mellon and formerly a part of the University of Pittsburgh.
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.
The School of Computer Science (SCS) at Carnegie Mellon University in Pittsburgh, Pennsylvania, US is a school for computer science established in 1988. It has been consistently ranked among the top computer science programs over the decades. As of 2022 U.S. News & World Report ranks the graduate program as tied for second with Stanford University and University of California, Berkeley. It is ranked second in the United States on Computer Science Open Rankings, which combines scores from multiple independent rankings.
Barry William Boehm was an American software engineer, distinguished professor of computer science, industrial and systems engineering; the TRW Professor of Software Engineering; and founding director of the Center for Systems and Software Engineering at the University of Southern California. He was known for his many contributions to the area of software engineering.
In software engineering, architecture tradeoff analysis method (ATAM) is a risk-mitigation process used early in the software development life cycle.
Software architecture analysis method (SAAM) is a method used in software architecture to evaluate a system architecture. It was the first documented software architecture analysis method, and was developed in the mid 1990s to analyze a system for modifiability, but it is useful for testing any non-functional aspect.
Randal E. Bryant is an American computer scientist and academic noted for his research on formally verifying digital hardware and software. Bryant has been a faculty member at Carnegie Mellon University since 1984. He served as the Dean of the School of Computer Science (SCS) at Carnegie Mellon from 2004 to 2014. Dr. Bryant retired and became a Founders University Professor Emeritus on June 30, 2020.
Mary Shaw is an American software engineer, and the Alan J. Perlis Professor of Computer Science in the School of Computer Science at Carnegie Mellon University, known for her work in the field of software architecture.
Gregory Dominic Abowd is a computer scientist best known for his work in ubiquitous computing, software engineering, and technologies for autism. He currently serves as the Dean of the College of Engineering and Professor of Electrical and Computer Engineering at Northeastern University. Previously he was the J.Z. Liang Professor in the School of Interactive Computing at the Georgia Institute of Technology, where he joined the faculty in 1994.
Universal systems language (USL) is a systems modeling language and formal method for the specification and design of software and other complex systems. It was designed by Margaret Hamilton based on her experiences writing flight software for the Apollo program. The language is implemented through the 001 Tool Suite software by Hamilton Technologies, Inc. USL evolved from 001AXES which in turn evolved from AXES all of which are based on Hamilton's axioms of control. The 001 Tool Suite uses the preventive concept of Development Before the Fact (DBTF) for its life-cycle development process. DBTF eliminates errors as early as possible during the development process removing the need to look for errors after-the-fact.
Software architecture description is the set of practices for expressing, communicating and analysing software architectures, and the result of applying such practices through a work product expressing a software architecture.
Bill Curtis is a software engineer best known for leading the development of the Capability Maturity Model and the People CMM in the Software Engineering Institute at Carnegie Mellon University, and for championing the spread of software process improvement and software measurement globally. In 2007 he was elected a Fellow of the Institute of Electrical and Electronics Engineers (IEEE) for his contributions to software process improvement and measurement. He was named to the 2022 class of ACM Fellows, "for contributions to software process, software measurement, and human factors in software engineering".
Attribute-driven design is a methodology to create software architectures that takes into account the quality attributes of the software. It was previously known as the Architecture Based Design Method, but due to trademark issues the name was changed to Attribute-driven design around 2001.
Jan Bosch is a Dutch computer scientist, Professor of Software Engineering at the University of Groningen and at Chalmers University of Technology, and IT consultant, particularly known for his work on software architecture.
Larry E. Druffel is an American engineer, Director Emeritus and visiting scientist at the Software Engineering Institute (SEI) at Carnegie Mellon University. He has published over 40 professional papers/reports and authored a textbook. He is best known for leadership in: (1) bringing engineering discipline and supporting technology to software design and development, and (2) addressing network and software security risks.
