Developing an Architecture-Focused Measurement Framework for Managing Technical Debt

billpollak — Mon, 23 Jan 2012 17:38:18 +0000

Managing technical debt, which refers to the rework and degraded quality resulting from overly hasty delivery of software capabilities to users, is an increasingly critical aspect of producing cost-effective, timely, and high-quality software products. A delicate balance is needed between the desire to release new software capabilities rapidly to satisfy users and the desire to practice sound software engineering that reduces rework. This blog post at the SEI blog by Ipek Ozkaya discusses how an architecture-focused analysis approach helps manage technical debt by enabling software engineers to decide the best time to rearchitect—in other words, to pay down the technical debt.

Rick Kazman on Evaluating Software Architectures

billpollak — Tue, 03 Jan 2012 15:23:19 +0000

Evaluating software architectures is a critical part of software architecture life-cycle processes. The book Evaluating Software Architectures: Methods and Case Studies covers the software architecture evaluation topic in detail focusing on evaluation frameworks such as Architecture Tradeoff Analysis Method (ATAM), Software Architecture Analysis Method (SAAM), and Active Reviews for Intermediate Designs (ARID). The authors also discuss in the book some case studies in applying these frameworks as well as comparison of the software architecture evaluation methods.

InfoQ spoke with Rick Kazman, Visiting Scientist at Carnegie Mellon University’s Software Engineering Institute (SEI) and a co-author of the book, about the significance of evaluating software architectures and how to perform the architecture evaluations in Agile and Lean software-development organizations. They also talked to him about the emerging trends.

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.

Here’s an excerpt:

The concert hall at the Syndey Opera House holds 2,700 people. This blog was viewed about 18,000 times in 2011. If it were a concert at Sydney Opera House, it would take about 7 sold-out performances for that many people to see it.

Stal and Hunt to Keynote the SATURN 2012 Conference

Dana Hanzlik — Wed, 14 Dec 2011 19:03:44 +0000

Michael Stal and Andy Hunt, two leading thinkers in the fields of software architecture and software engineering, will deliver keynote presentations at the SATURN 2012 conference. SATURN is the Software Engineering Institute’s annual conference devoted to software and systems architecture. SATURN 2012 will be held May 7-11, 2012 at the Hilton St. Petersburg Bayfront hotel in St. Petersburg, Florida.

Michael Stal is principal engineer at Siemens Corporate Research and Technologies. His main research topics address software architecture for distributed and/or embedded systems. He coaches projects within the various business units at Siemens and is in charge of educating the Siemens senior software architects. Stal earned a PhD from the University of Groningen where he has been appointed professor for software engineering. In addition, Stal co-authored the Pattern-Oriented Software Architecture (POSA) book series.

Andy Hunt is a programmer turned consultant, author, and publisher. Hunt was one of the 17 founders of the Agile Alliance and also one of the authors of the Agile Manifesto. He co-founded the Pragmatic Bookshelf, publishing award-winning and critically-acclaimed books for software developers. He also has authored award-winning and best-selling books, including The Pragmatic Programmer, co-written by Dave Thomas, and six other books, including the his latest, Pragmatic Thinking and Learning.

In line with the SATURN 2012 conference theme “Architecture: Catalyst for Collaboration,” both keynote speakers will explore how practitioners can collaborate effectively across geographical, cultural, and technical boundaries to solve system problems.

See the SATURN 2012 website in January 2012 for more details about the keynote addresses as well as the preliminary conference program.

Workshop on Managing Technical Debt at ICSE 2012

Robert Nord — Tue, 13 Dec 2011 20:05:16 +0000

On June 5, 2012 we will be organizing a workshop co-located with the International Conference on Software Engineering (ICSE 2012) in Zurich to scrutinize the diverse issues that are related to technical debt and the software development lifecycle. The details of the call for papers and other logistics are at our workshop site. We invite practitioners and researchers to join us in discussing early findings, future directions, experiences, and results.

An initial workshop was held at the Software Engineering Institute in Pittsburgh on June 2–4, 2010. The outcomes of this workshop and open research questions are outlined in the position paper Managing Technical Debt in Software-Reliant Systems presented at the FSE/SDP 2010 Workshop on the Future of Software Engineering Research. The second workshop was held collocated with ICSE 2011. A summary of the workshop is available in the September 2011 issue of ACM SIGSOFT Software Engineering Notes.

The technical debt metaphor is gaining significant traction in the software development community, as a way to understand and communicate issues of intrinsic quality, value, and cost. The idea is that developers sometimes accept compromises in a system in one dimension (such as modularity) to meet an urgent demand in some other dimension (such as a deadline), and that such compromises incur a debt on which interest has to be paid and which should be repaid at some point for the long-term health of the project.

The power of the metaphor is that it communicates the essence of the tradeoffs that are at the core of many software engineering decisions–balancing economic outcomes while continuing to meet business and user needs. However, the more the metaphor resonates the more there is the need to understand the quantifiable and scientific principles to avoid confusion.

In addition, today the metaphor is used not only to refer to suboptimal coding and refactoring practices as it was originally used by Ward Cunningham, but also to describe issues observed during different software development activities: requirements debt, testing debt, and architectural debt to name a few.

As part of our Communicating the Value of Architecting within Agile Development project, we have been working on technical debt from the perspective of strategic architecture-related technical debt with Philippe Kruchten from the University of British Columbia.

The workshop has the broader goal to discuss managing technical debt as a part of the research agenda for the software engineering field, in particular focusing on eliciting and visualizing debt and creating payback strategies.

Record Number of Abstract Submissions for SATURN 2012

billpollak — Mon, 05 Dec 2011 18:44:33 +0000

The SATURN technical committee and I are delighted by the number of people who showed interest in presenting at SATURN 2012 by submitting abstracts in response to our call for submissions. We had our highest number of abstracts ever this year, 92!, far exceeding our previous high of 73 submissions last year. Clearly there is growing interest in software architecture and in the SATURN Conference. The topic of this year’s conference–Architecture: Catalyst for Collaboration–spurred authors to submit on a wide variety of topics, including traditional uses of architecture (such as in coordinating large, distributed, or challenging projects), as well as more recent developments such as using architecture in Agile design evolution, outsourcing, and coordinating multiple Agile projects.

In the next several weeks, the program committee will be reviewing these proposals and crafting a high-quality technical program for SATURN 2012. We plan to notify presenters sometime during the first week in January about the status of their submissions. With such a large number of submissions, the conference must be more selective, and the acceptance percentage will be lower this year than in past years. My quick scan of the abstracts tells me that we will have some difficult decisions to make.

Thank you for your interest and engagement with SATURN 2012. We look forward to seeing you in St. Petersburg, Fl. May 7-11.

Interview and Book Review: Documenting Software Architectures: Views and Beyond, 2nd Edition (InfoQ)

billpollak — Wed, 02 Nov 2011 15:06:41 +0000

Software architecture—the conceptual glue that holds every phase of a project together for its many stakeholders—is widely recognized as a critical element in modern software development. Practitioners have increasingly discovered that close attention to a software system’s architecture pays valuable dividends. Without an architecture that is appropriate for the problem being solved, a project will stumble along or, most likely, fail. Even with a superb architecture, if that architecture is not well understood or well communicated the project is unlikely to succeed.

Documenting Software Architectures: Views and Beyond, 2nd Edition by Paul Clements and 8 other authors provides the most complete and current guidance, independent of language or notation, on how to capture an architecture in a commonly understandable form.

See this book review and interview with co-author Paulo Merson in the November 1 edition of InfoQ.
