The New Economic Challenge Todays businesses face rapidly changing conditions, new technology, new competitive forces and new consumer trends. As we look at the horizon, we see dramatic change standing out : Volatility is here to stay. Scaling operations up and down as conditions changes and ability to pivot quickly and address new threats or opportunities are what make companies successful in todays economy. Todays market volatility is increasing. Products have life cycles measured in months or a couple of years at most. Technology and consumer preferences are rapidly evolving. New fashions and new products and whole product categories pop up without warning, drastically altering traditional customer buying patterns. Not only is product demand hard to estimate, but so too are the costs of everything from raw materials to labor and transportation. The real-time global economy of the twenty-first century is a very different world from that of the last century. Today, responsiveness and flexibility are key words for success. But to effectively implement flexibility and responsiveness into their business, organization's strategies MUST find a way to shift sunk costs into variable costs. In that way, as operating costs rise as business activity rises, and costs will also drop as activity drops and costs wont rise at all if expected activity levels dont materialize or a new product doesnt take off. So, lets find a way to build a computing model flexible enough to support this new business environment volatility. </li> <li> 4. What this module Stands for ?

The New Corporate Business Structure : From Hierarchical Model to Network Model </li> <li> 8. Supply creates its own demand, one can not have overproduction. You surely remember this sentence from Jean Baptiste SAY. JB SAY said that in the eighteenth century; At that time product demand was reasonably predictable and stable; so companies had just to allocate labor and capital to optimize production and Return On Investment (ROI). In that context, ability to lower transaction costs, product cost and gain efficiencies from economies Of scale were enough to be successful. Since it was possible to make reasonably reliable predictions of customer demand and prices for labor and raw materials, companies gather themselves into huge and vertically integrated conglomerates. In that way, they were able to make large capital investments in plant and equipment to achieve economies of scale and meet demand for their products at the lowest per-unit costs, and thus earn the greatest profits. They paid for these investments and their resulting high fixed costs through increases in productivity that enabled them to produce greater and greater amounts of standard goods and services at lower and lower costs. Naturally, this leads to tendency to organize themselves as hierarchical pyramids where most people are powerless workpeople who just follow orders while the important decisions are made by a small group of powerful executives at the top of the pyramid. But that, that was Before ! </li> <li> 9. The Hierarchical Pyramid Model Decision-Maker Control Business Units Orders Information In Centrally controlled hierarchies, People at the top of corporate hierarchies are overwhelmed by the sheer volume of decisions they have to make; they are too far away from the scene of the action to really understand whats happening; and by the time decisions are made the actions are usually too little and too late Centrally controlled hierarchies move SLOWLY because only a few people know what the strategy is and everybody else waits for permission to act </li> <li> 10. But Today, businesses face rapidly changing conditions, new technology, new competitive forces and new consumer trends. Market volatility is increasing. Scaling operations up and down as conditions changes and ability to pivot quickly and address new threats or opportunities are what make companies successful in todays economy. Today Products have life cycles measured in months or a couple of years at most. Technology and consumer preferences are rapidly evolving. Not only Product demand is hard to estimate, but so too are the costs of everything from raw materials to labor and transportation. The real-time global economy of the twenty-first century is a very different world from that of the last century. Today, responsiveness and flexibility are key words for success. Companies need to be agile and they can no longer follow the traditional hierarchical model where there is such a high fixed costs and a decision-making bottleneck at the top of the organization. They need something more agile, something that can help them turn fixed costs into variable cost. Like this, as operating costs rise as business activity rises, and costs will also drop as activity drops and costs wont rise at all if expected activity levels dont materialize or a new product doesnt take off. Now instead of a small group of executives telling everybody else what to do, people should have authority to figure out for themselves what to do. People should be motivated to coordinate, cooperate, and collaborate with each other by a financial incentive system that rewards them for their common successes instead of rewarding each manager for their individual successes. The evolution of corporate organization structures like this is driven by the convergence of economic necessities with technological capabilities :That is where Cloud Computing comes in to play ! </li> <li> 11. The Network Model : A Model of Responsive Organization Business Unit 2 Coordination In a responsive organization, Enterprise Coordinator says WHAT. Business Units are free to choose HOW Business Unit 1 Business Unit 4 Business Unit 3 Business Unit 5 New Unit 2 Coordination requires everybody to know what the strategy is and have authority to act. Business units become new coordinators to support expansion into new market New Unit 1 </li> <li> 12. Cloud Computing : A Business Strategy based on Agility </li> <li> 13. In volatile time like today, Business models with high fixed costs are much riskier than they used to be. Reactiveness generate efficiency; a better strategy is to shift fixed costs into variable costs. A responsive model gives flexibility to adapt to changes as quickly as they happen. A lot of companies have high fixed operating costs because of IT investments in computers, business application systems, data centers and staff needed to run the technology and systems. Or investment in IT cannot be easily reconfigured to adapt to changes. Ironically, these IT systems are a critical factor in any companys ability to be agile and responsive. Recent studies shows that about 70 to 80 % of company IT budgets goes to the operation and maintenance of existing systems and data centers. So in many organizations, there isnt much money available to design and develop new systems. Given this situation, consider this axis of reflections: What if companies could outsource their IT Infrastructure with all ongoing costs to a highly specialized provider ? If companies cannot have to worry anymore about all of the financial and operational overhead associated with building and operating their own data centers, would they then be able to focus more on what they do as a business? Companies have today the big opportunity to reduce IT Costs by reducing unused IT Infrastructure capacity through what is called CLOUD COMPUTING. In effect, some companies (providers) are now offering their computing power and software applications on a Pay-as-you-go basis. With this opportunity, companies can now power their business operations with a flexible and Scalable Computing Platform ! </li> <li> 14. What is Cloud Computing Anyway !? There is numerous definitions about Cloud Computing and Vendors are constantly framing cloud from an IT perspective, and fighting over confusing cloud definitions, leaving business leaders unclear of the corporate or competitive importance. But here are some definitions : - IDC (International Data Corporation) : Consumers and business products, services and solutions delivered and consumed in real time over the internet. - IBM : Cloud computing is a pay-per-use consumption and delivery model that enables real-time delivery of configurable computing resources (for example, networks, servers, storage, applications, services). Typically, these are highly scalable resources delivered over the Internet to multiple companies, which pay only for what they use. - Microsoft : An approach to computing thats about internet scale and connecting to a variety of devices and endpoints - Jeff KAPLAN : . . . a broad array of web-based services aimed at allowing users to obtain a wide range of functional capabilities on a pay-as-you-go basis that previously required tremendous hardware/software investments and professional skills to acquire. In a Cloud Computing architecture, one or more companies provide online Computing resources (Services) to another companies that the latter pay on a pay-as-you-go basis. </li> <li>...</li></ul>
