Gartner quotes Roger Sessions's White Paper, The Mathematics of IT Simplification" in their prediction that IT Complexity Management will be one of the top ten IT trends between 2013 and 2015. Click <here>

CIO quotes Roger Sessions extensively in this article about IT Complexity. "How much do you think IT project failures cost annually on a global basis? In his 2009 white paper, The IT Complexity Crisis: Danger and Opportunity, Roger Sessions, CTO of ObjectWatch, a consultancy specializing in IT architecture and systems complexity, estimated the cost to be roughly $6.2 trillion per year with the U.S. accounting for some $1.2 trillion of that total." Click <here>

Network World carried this interview with Roger Sessions. "The basic problem is the larger and more expensive an IT project is, the more likely it is to fail. You can do a lot of analysis as to why that is. You can say maybe we're not using the right methodology, or communications is failing, or any number of things. But ultimately the only variable that appears to correlate closely with failure is complexity." Click <here>

ITBusiness Edge quotes Roger Sessions in this article about IT project failures. "So it's not too surprising that Roger Sessions, chief technology officer at ObjectWatch Inc., author of Simple Architectures for Complex Enterprises and a man of many accomplishments judging by his bio, says complexity is the single largest cause of software failures." Click <here>

ZDNet discusses Roger Sessions's article on IT Project failures. "To address this issue, Roger Sessions, a noted author and expert on complexity, developed a model for calculating the total global cost of IT failure. " Click <here>

InfoQ discusses Roger Sessions's ideas on SIP. "Sessions says that 'the key is thinking small, partitioning the organization into narrowly defined areas of business need, instead of attempting to define the architecture for the entire company'; then, build out these features in an iterative fashion, showing early value and success in the EA project. Sessions last year proposed this new methodology, calling it the Partitioned-Iterative Approach to Enterprise Architecture, a process drawn from the lessons of probability theory and war strategy."

ComputerWorld discusses Roger Sessions's ideas on IT complexity. "Is the problem a bad set of user requirements? Poor business alignment? No. According to software architect Roger Sessions, the primary cause of software project failures is complexity." Click <here>

ComputerWorld NZ interviews Roger Sessions on IT Complexity. "When a large, complex, expensive IT system fails, the last thing anybody wants to understand is the cost of that failure. At the executive level, most energy is spent showing that first of all, the failure wasn’t really that bad, and second of all, it was really somebody else’s fault. Blame avoidance, not failure avoidance, is the standard operating procedure in most large organisations." Click <here>

The IT Media Group quotes from Roger Sessions paper on The IT Complexity Crisis. "Roger Sessions, CTO of ObjectWatch, writes, 'IT failures are rampant in the private sector, the public sector, and the not-for-profit sector. No place is safe. No industry is protected. No sector is immune.' Sessions argues that failure to manage IT complexity is the single biggest reason that IT systems so often fail. And when complexity is the culprit, the failures are catastrophic, expensive, and usually highly visible." Click <here>

InformationAge interviews Roger Sessions for their article. "If simply dividing IT systems into smaller, manageable subsystems guaranteed success, then IT projects based on service-oriented architecture (SOA) –in which application functionality is split into discrete web services –should have a 100% success rate. However, as consultant and IT complexity expert Roger Sessions found when working on SOA projects, this was far from the case. 'It seemed like SOA should just work, because you’re splitting the system down into smaller and smaller pieces,' he says. 'So I became interested in why so many SOA projects were failing.' Sessions came to the realisation that, while the individual components of an SOA might be simple, the interdependencies between services were often highly complex."

Business Analyst Times quotes Roger Sessions. "With business success riding on innovation and first-to-market speed, we must be able to deliver on project commitments However, according to the CHAOS Report 2011 by the Standish Group, business change initiatives that rely heavily on IT are only 37% successful, as measured by on time, on budget, and with the full scope of functions and features. What is the cost of the other 63%, the failed and challenged projects? According to Roger Sessions, the cost is USD 1.22 trillion/year in the US, and USD 500 billion/month Worldwide. So project success equates to global competitiveness and financial stability." Click <here>

Modern Analyst.com discusses Roger Sessions. "Roger Sessions, in his thought provoking paper The IT Complexity Crisis: Danger and Opportunity, describes an IT industry in deep distress. Roger lays the blame for poor, even catastrophic, IT productivity at the door of complexity." Click <here>

Information Week highlights paper by Roger Sessions. "Ivory towers tend to increase the complexity and upset the stakeholders. The new CIO will gain immediate recognition among his business partners by firing the EA team, with the result that enterprise architecture becomes a bad word deeply embedded in the institutional memory. Roger Sessions wrote a great white paper on driving simplicity through connected enterprise architecture." Click <here>

TechWorld discusses Roger Sessions's ideas. "So the question is not, are we failing? We know we're failing. The question is, why aren't we doing something about it? Why do we keep doing the same thing over and over again if we can see very clearly how unsuccessful it is?" Click <here>

PEI quotes Gartner quoting Roger Sessions's definition of Glass's Law. "Pointing to Glass’s Law (sourced to Roger Sessions of ObjectWatch), which states that 'for every 25 percent increase in functionality of a system, there is a 100 percent increase in the complexity of that system,' Gartner predicts there will be an emphasis on the ability of an enterprise to get the most out of I.T. money spent." Click <here>

TechWorld Australia interviews Roger Sessions on complexity. "Is the problem a bad set of user requirements? Poor business alignment? No. According to software architect Roger Sessions, the primary cause of software project failures is complexity. Complexity can create delays, cost overruns and systems that don't meet business needs, according to Sessions, who is chief technology officer at ObjectWatch Inc." Click <here>

ComputerWorld UK interviews Roger Sessions on his SIP methodology. "SIP uses a mathematical technique called equivalence relation analysis to find the best possible balance between 'making the system small and minimizing functionality related complexity, and keeping the system large and minimizing dependency related complexity,' Sessions says. The result is an optimized number of subprojects that have a far greater chance of success, he says." Click <here>

Lab Soft News quotes Roger Sessions on complexity. "Roger Sessions defined a model (Cost of IT Failure) that quantifies the dollar cost of IT failure worldwide." Click <here>

Internet Media Labs debates Roger Sessions theories on IT complexity. :"Roger Sessions, a Fellow of the International Association of Software Architects, wrote a post on Simplicity in Architecture, in which he argued that simplicity was an attribute that could be baked into software architectures and solutions in much the same manner as portability, manageability and reliability. Sessions further implied that simplicity, or simplility as he coined it, was more important than many of the other attributes as it’s the attribute from which all others flow. In other words — simplicity is the basis for most, if not all, of those attributes, and the converse tends to prove it." Click <here>

Fierce CIO; The Executive Management Briefing discusses Roger Sessions and IT complexity. "Systems are getting larger and larger and they're already to the point where they have a very high probability of failure," Sessions says. "So we have a cycle. The cost of the system goes up, the cost of the failures goes up, and the chances of success drop. As the chances of success drop, the cost of the system goes up more. And as the cost of the system goes up more, the failure rate increases." Sessions obviously advocates small systems, although they can create a new set of complications. His company was recently granted a patent for an anti-complexity methodology, Simple Iterative Partitions, which aims to simplify business and IT systems." Click <here>

Networks Asia quotes Roger Sessions on IT complexity. "Sessions' remedy is a software design process called Simple Iterative Partitions, which partitions business functions into subsystems in a way that makes the overall system as simple and reliable as possible to achieve the business goal." Click <here>

CIOZone discusses Roger Sessions. "Among those who see complexity as the root cause of the problem is Roger Sessions, who in a whitepaper entitled "The Complexity Crisis; Danger and Opportunity," dated November 8, 2009, issued a dire warning, asserting that: "The coming meltdown of IT; the out of control proliferation of IT failure is a future reality from which no country -- or enterprise -- is immune....IT failures are rampant in the private sector, the public sector, and the not-for-profit sector. No place is safe. No industry is protected. No sector is immune. This is the danger, and it is real."" Click <here>

Market Wired quotes Roger Sessions. "IT simplicity is a key business asset. It enables efficiency, agility, and scalability. Complexity is an IT killer. It causes delivery delays, cost overruns, and is the single greatest source of business frustration with IT." Click <here>
