CISQ Interviewed by SD Times – Dr. Bill Curtis (CISQ) and Dr. Richard Soley (OMG) Cited

Read About CISQ’s Mission, Standards Work, and Future Direction   Tracie Berardi, Program Manager, Consortium for IT Software Quality (CISQ)   Rob Marvin published an article in the January issue of SD Times that details the work of the Consortium for IT Software Quality (CISQ). Rob interviewed Dr. Richard Soley, CEO of the Object Management Group (OMG) and Dr. Bill Curtis, Executive Director of CISQ.  The article sheds light on the state of software quality standards in the IT marketplace.   I can supplement what’s covered in the article for CISQ members.   CISQ was co-founded by the Object Management Group (OMG) and the Software Engineering Institute (SEI) at Carnegie Mellon University in 2009.   Says Richard Soley of OMG, “Both Paul Nielsen (CEO, Software Engineering Institute) and I were approached to try to solve the twin problems of software builders and buyers (the need for consistent, standardized quality metrics to compare providers and measure development team quality) and SI’s (the need for consistent, standardized quality metrics to lower the … Continue reading

CISQ to Start Work on Automated Enhancement Function Point Specification

By Tracie Berardi, Program Manager, Consortium for IT Software Quality (CISQ)   In January 2013 CISQ published a specification for Automated Function Points (AFP) that enables the automated sizing of software by function points. The spec was developed by an international team led by David Herron of the David Consulting Group. The CISQ AFP spec was designed to be as similar as possible to the IFPUG Counting Guidelines, but also to be objective so counts are consistent (the same every time) and can be automated for use in tools. You can learn more about AFP here.   In 2015 CISQ begins work on a specification for Automated Enhancement Function Points (AEFP). The existing AFP specification is not suitable for productivity analysis, as it does not solve the problem of measuring maintenance work which does not change the total number of function points even after substantial changes to the code.   The primary challenge is to identify a counting or weighting method for AEFPs that is correlated with maintenance effort – … Continue reading

How Do You Measure System Complexity?

By Tracie Berardi, Program Manager, Consortium for IT Software Quality (CISQ)   Chris Kohlhepp proposed the Law of Tangental Complexity in an article he wrote on the complexity of large scale systems. He explains: To successful systems we add functionality, inter-dependencies, and layers of abstraction. Pressures exist to continue adding value. Over time systems become so complex that they eventually reach a “cognitive horizon,” i.e. a psychological limit on the ability of humans to understand the complexity of the system. We may add lateral breadth of functionality to the system (tangent to the cognitive horizon), but in time, control is lost and TECHNICAL DEBT ensues.    Image credit: Chris Kohlhepp, Law of Tangental Complexity   As steps are taken to make the system manageable – refactoring, and perhaps the hiring of new staff – the system will again find itself nearing an even greater cognitive horizon. “Recruiting more exceptionally talented engineers who can cope with the cognitive horizon of the system proves less fruitful upon later iterations of this cycle,” … Continue reading

Software Risk Management

By David Gelperin, CTO, ClearSpecs Enterprises   40-60% of larger projects fail. Fewer smaller projects fail. Therefore, do smaller projects.   It’s safer to do projects you have done successfully before, e.g., build another ecommerce website. Therefore, repeat successful projects.   If you must do something larger and unfamiliar, identify its hazards and how you plan to mitigate them.   Functions are the goals that customers care about and focus on. Developers are told to focus on customer value. Qualities like security, privacy, reliability, and robustness are goals that customers rarely think about.    Functions are easy. Qualities are hard. When system failures make the news, e.g., security breaches, it is rarely because of a functional failure. Qualities are commonly missing from software estimates and inadequately supported in operational software.    Quality may be free, but qualities need investment. Providing a quality is nothing like providing a function. Qualities are dangerous because they are unfamiliar and out of focus.   Current Agile development ignores qualities or treats them like functions. … Continue reading

The Other Requirements

By David Gelperin, CTO, ClearSpecs Enterprises   Bob, the developer, is excited. This is his first assignment with his new employer and he really wants to show them what he can do. They are asking him to develop a “make a hotel reservation” function and he is listening carefully to understand exactly what they want. He has done something similar, except for rental cars. He asks a few clarifying questions and feels fortunate that they asked him to do something he is familiar with.   He heads back to his office to develop an estimate and then tells Sue, his supervisor, that he is ready to begin work. When he meets with Sue, she asks if he has included the relevant “crosscutting requirements” in his estimates. Bob is not sure, because he doesn’t understand what she is asking.   She explains that understanding the domain function is important, but its associated crosscutting requirements need to be understood as well and factored into estimates. Crosscutting requirements constrain multiple domain functions or … Continue reading

Seeking Beta Sites for Quality-First Agile Development

By David Gelperin, CTO, ClearSpecs Enterprises   Seeking sites to refine and use a hybrid Agile process containing two phases. The second phase is “pure” Agile development and focuses on user functions. The first phase (Quality-First) identifies and manages quality goals such as reliability, understandability, or response time, which matter to your application.   Quality-First contains the following steps:   1. Identify relevant quality goals and their acceptable quality levels early (workshop).   Some quality goals are universal that are relevant to most applications. These include: reliability, response time, modularity, ease of use and learning, and all basic qualities (compliance, sufficiency, understandability, and verifiability).   The remaining (nonuniversal) quality goals are reviewed to identify those which matter to your application.   <A comprehensive quality model will be supplied to speed this step>   2. Refine quality goal information and identify “quality champions” among your team.   3. Create master lists of development restrictions including quality constraints and design, coding, and verification tactics derived from your quality goals.   Each quality … Continue reading

What is Quality?

By Bill Ferrarini, Senior Quality Assurance Analyst at SunGard Public Sector, and CISQ Member   Quality is more than just a word, it’s a passion of mine.   In 1974 I was fortunate enough to experience Quality Circles. It was definitely that moment, when you realize that you can make a difference. I got into the PC software development industry in the early days, at a time when the Industry was in need of a direction, an industry crying for standards and quality. The first decade of this emerging industry was extremely tumultuous, a young industry struggling with its identity, finding the players that would shape it into what it is today, a multi-billion dollar industry.   Somewhere along the journey, quality became important to companies who developed and published software. Providing software that was relatively ‘bug free’ took the industry by storm. In the early 1980s, companies, left and right, were adopting Best Practice guidelines like ISO 9000. An entire industry of management and training in the art of … Continue reading

Interesting Interview – The Internet of Things and the Honda Recall: An Interview with Anders Wallgren

By Tracie Berardi, Program Manager, Consortium for IT Software Quality (CISQ)   In case you didn’t catch this interview with Anders Wallgren, CTO of Electric Cloud, I’m circulating it here. On August 8, 2014 Anders was interviewed by StickyMinds editor, Cameron Philipp-Edmonds about the recent Honda recall and lessons learned (and to be learned) as we develop the “internet of things.”   You can read or watch the interview here: http://www.stickyminds.com/interview/internet-things-and-honda-recall-interview-anders-wallgren   Software is pervasive. As Anders notes in the interview, even cars can contain two- to three- hundred million lines of code. (Wow!) “Today you’ve got lots of systems interacting in cars with each other, every car these days is basically a distributed network of computers that need to operate together,” he says. It won’t be long before cars are driving themselves.   Honda is recalling thousands of vehicles because of a pesky software bug that impacts acceleration. High profile quality issues like this are popping up more and more, and consumers are taking notice. Consumers have more avenues … Continue reading

So you want to implement Quality Assurance… or should it be Quality Control?

By Bill Ferrarini, Senior Quality Assurance Analyst at SunGard Public Sector, and CISQ Member   Most companies will use these terms interchangeably, but the truth is Quality Assurance is a preventative method while Quality Control is an Identifier.   Don’t go shooting the messenger on this one, I know that each and every one of us has a different point of view when it comes to quality. The truth of the matter is we all have the same goal, but defining how we get there is the difficult part.   Let’s take a look at the different definitions taken from ASQ.org.   Quality Assurance Quality Control The planned and systematic activities implemented in a quality system so that quality requirements for a product or service will be fulfilled. The observation techniques and activities used to fulfill requirements for quality. Quality Assurance is a failure prevention system that predicts almost everything about product safety, quality standards and legality that could possibly go wrong, and then takes steps to control and prevent flawed products or … Continue reading
