A critical strategy for reducing cybersecurity complexity is unifying your security posture. Cyclomatic complexity for this method is 19 and it’s too complex. But, she acknowledges, it’s not easy to achieve this state. By reducing complexity we can remove unnecessary costs and organisational friction and improve our ability to adapt quickly. Complexity could mean that design flaws or defects could lead to hazardous conditions that are undiscovered and unresolved. It usually misses something, leading to multiple rounds of rework and patches that make the final system ever more complex. The following example shows how to use reduction from the halting problem to prove that a language is … It’s a battle you wage every day. While new capabilities are welcome, they require more thorough validation. Except the fact that rising complexity is here to stay as a new fact of our profes… And you can’t hand off the problem to a service provider. The seats might be movable but not the lighting—a seemingly minor detail, but one that might prevent airlines from configuring the seating to differentiate between first class and coach. Today, all CIOs are standing in the path of a fire hose spewing complexity. And that adds complexity. Dr. Sheard has more than 20 years of experience in systems engineering, software and systems process improvement, and complexity science. This digging causes the delays that frustrate business executives and CIOs alike whenever change or progress is needed, says Mark McDonald, group vice president for Gartner executive programs. Change will require expensive retrofitting of technology to handle what the architecture hasn’t anticipated. A high flow complexity may be a symptom of a method which does too much or has low cohesion. CIOs can—with difficulty—handle these challenges individually, one at a time. Increase … Ironically, as Accenture CIO Modruson notes, “Complex things tend to be easier to design and deploy.” Many enterprises justify Rube Goldberg-type systems by saying they need them now and promising themselves that they’ll clean up the technology later. Technology continues to change, and business demand for services continues to increase,” says Wal-Mart CIO Rollin Ford. . Deliver insights for one of the customer profiles; collect information from external as well as internal sources about that particular customer. McGraw-Hill, 2004. Palgrave Macmillan, 2012. This approach also ensures that business-IT conversations don’t devolve into throwing requirements over the wall, an approach that usually adds complexity in two ways. At Motorola, Morrison ensures that her architecture accommodates and anticipates business goals by using business process management (BPM) principles and an enterprise reference architecture to define a common language for business and IT. These processes must then be reconciled, which frequently requires custom interfaces for other systems that no one (certainly not the business) realized would be affected. Reduce Maintenance Cost. Without it, business units end up clamoring for their own unique variants of, say, customer information. It is worth to mention that the time spent in the analysis will reduce complexity. An architectural approach is essential to managing complexity, says Motorola CIO Patty Morrison, and you need one mapped to business objectives. But “later never happens,” Modruson says dolefully. Function Point concentrates on functionality provided by the system. For example, you would ensure the application is network-agnostic and supports both always-on connections and intermittent connections. Outside of IT’s direct control, complexity is increased by the requirements of compliance, the need to support global business, and the speed and depth of access to information demanded by your customers and your partners. Some CIOs have figured out ways to escape the complexity trap. Reduce IT Complexity, Costs with Consolidation, Managing IT Complexity: Survival Techniques, “IT complexity acts as a significant tax on IT value,” says Bob Zukis, a partner at PricewaterhouseCoopers. No one lives in the complexity space; no one has a packaged solution to the complexity problem. But in the real world CIOs face many, if not all, of these challenges, all at once, over and over. From Complexity to Simplicity: Unleash Your Organisation’s Potential. When evaluating the complexity implications of any business or IT effort, CIOs will need to accept, in some cases, more complexity than is ideal because of the business benefit, says Vincent. “You very, very much need to have an end-state architecture in place—a description of where you’re headed,” she says. In times of increasing complexity, confusion is the new normal and complexity management enters center stage.There are very few one-way streets in society and business these days. It is tough to reduce the complexity of the system once it is fully completed and is about to be released. 2 that reports the increasing number of lines of code … Complexity is not something you get rid of once and for all. … Improve Code Quality. They reduce complexity where possible; they live with what remains; they still invest in new technologies that can lead to business success. It’s called Moore’s Flaw, the flip side of the famous axiom that has driven the furious pace of IT innovation for several decades. It is a quantitative measure of the number of linearly independent paths through a program’s source code. Dow has a group of IT and business staff whose job is to track these subsets and make sure they conform to the overall architecture—or adapt the architecture if that’s what’s needed. Even leading scientists, leaders and experts disagree about a lot. In this podcast, Sarah Sheard discusses research to investigate the nature of … And although ING is re-architecting some of its global systems for more common processes and technology, the Asia business can’t grow if it has to mark time while that effort is completed. Because both business and technologies change, you can’t always have a multiyear plan for a specific result, says Mack Murrell, vice president of IS at Dow Chemical. It also allows him to gauge how a technology will affect future changes to both the business and the IT infrastructure. The complexity classes L, NL, P, NP and PSPACE are closed under log-space reduction. This means that even CIOs who are good at managing complexity can never, ever rest. The challenge of complexity is exacerbated by the fact that many organizations have technology systems that have been built up over time or acquired through acquisitions or complicated by many waves of vendor consolidation. That’s why CIOs and their business partners must have strong governance “about what really impacts our customer, with business a key part of that decision structure,” says Michael Vincent, CIO of global financial services provider ING. It enables him, Vincent says, to figure in the impact of complexity not just on deployment but also on maintenance and integration, which consumes about 70 percent of IT’s budget. She has authored several publications on systems and software ... Dr. Sarah Sheard is a senior engineer in the SEI's Software Engineering and Acquisition Practices Directorate. From the course’s description: The market for facial recognition is expected to double by 2024 to … One approach to accomplish this is to begin assessing each operation or subassembly for quality rather than performing only an end-of-line style quality check. Programming complexity (or software complexity) is a term that includes many properties of a piece of software, all of which affect internal interactions.According to several commentators, there is a distinction between the terms complex and complicated. For these companies, moving forward requires an almost archaeological effort to unearth, understand and work with all these layers of sedimentary technology. In this post we will focus on how you can reduce the complexity of your “assumption” properties to make them easier for the formal engines to digest and reach a solution. Essentially the easiest way to explain complexity is to count all the branches in your code. “Complexity leads to brittleness and high costs,” notes Frank Modruson, CIO of Accenture. Rather, Morrison says, the CIO’s architecture has to be driven first by key business processes. Conquering Complexity in Your Business: How Wal-Mart, Toyota, and Other Top Companies Are Breaking Through the Ceiling on Profits and Growth. Prioritize your business critical data i.e. These suggestions help developers avoid coding errors and reduce complexity. e = 10 n = 8 Cyclomatic Complexity = 10 - 8 + 2 = 4 According to P. Jorgensen, Cyclomatic Complexity of a module should not exceed 10. IT is a fast-changing industry - that is something that all of us can readily accept. Even more important, businesses that successfully address complexity can be more agile because their systems don’t get in the way of business process change. 3.Complexity cannot be handled when the feature or application is fully developed. Just like online banking, infrastructure management software simplifies the view into hybrid IT environments and allows IT managers to save significant time and reduce complexity. “When you reduce complexity, you increase your ability to implement new solutions,” says André Mendes, CIO of the Special Olympics. Moore’s Flaw posits that keeping up with this flood tide of innovation quickly becomes too difficult (and too costly) for anyone to manage. Rearrange. Ignoring those factors would result in a plane that flew but couldn’t adapt to its customers’ business needs. “When you reduce complexity, you increase your ability to implement new solutions,” says André Mendes, CIO of the Special Olympics. Ask any software engineer who has built one and they will tell you that multi-tenant applications are inherently more complicated than single-tenant applications. It’s those organizations that “have managed complexity out of their environments that are reaping the value from their IT spends.”. Dr. Sarah Sheard is a senior engineer in the SEI's Software Engineering and Acquisition Practices Directorate.
