3 Ways APIs are Driving the Mobile App Revolution It wasn’t long ago that application programming interfaces (APIs) were strictly the domain of IT departments and developers. APIs were complex and had to be carefully maintained. Things have quickly and dramatically changed. At the end of 2012, there were approximately 7,000 APIs globally, double the number that existed just the year before. Here are three factors that have lead to this explosion of API growth: 1. Over the past decade, cloud computing and Platform as a Service (PaaS) have been critical when it comes to helping businesses innovate quickly. 2. Mobile and the rise of the app economy have opened the API floodgates. 3. Connected devices designed for both consumers and businesses will fuel the next wave of API growth.

Thinking in Systems by Donella Meadows "Dana Meadows' exposition in this book exhibits a degree of clarity and simplicity that can only be attained by one who profoundly and honestly understands the subject at hand--in this case systems modeling. Many thanks to Diana Wright for bringing this extra legacy from Dana to us."—Herman Daly, Professor, School of Public Policy, University of Maryland at College Park In the years following her role as the lead author of the international bestseller, Limits to Growth—the first book to show the consequences of unchecked growth on a finite planet— Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Meadows’ newly released manuscript, Thinking in Systems, is a concise and crucial book offering insight for problem solving on scales ranging from the personal to the global. Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. About the Author Donella Meadows
Freebase The Key Components of a Mobile App Strategy There is no question that mobile apps are the future of commerce. Not when the writing on the digital wall tells us that some 25% of online retail is bound for smartphones and tablets by 2017. That doesn't mean that your company is automatically clear on what to do, exactly. What is your mobile app strategy? And how can you front-load it for success? Getting to what and how starts with asking why. The answer lies in the way(s) that your clients use your services and buy your products. Next, how? Let's look at some key components of your strategy for making this happen. Focus on Experience Mapping out the user experience is the first key component. Your mobile-app strategy begins with the idea of interaction. "Many times our customers think we're designing interfaces to be pretty and pleasing to the eye," says Sean Mahoney, president and CEO of AndPlus. Success as a "Guts-Out" Approach Your strategy starts with user experience, but then it needs to incorporate developer empowerment.

Leveraged together, they contribute heavily to the success of learning organizations, defined by Senge as, “…organizations where people continually expand their capacity to create the results they truly desire, where new and expansive patterns of thinking are nurtured, where collective aspiration is set free, and where people are continually learning to see the whole together.” The five learning disciplines are Personal MasteryMental ModelsShared VisionTeam LearningSystems Thinking For descriptions of each of these disciplines, visit the Society for Organizational Learning’s website.
