Decentralize
[P.83]
We want to be global and local, big and small, and radically decentralized with centralized reporting and control. If we resolve those contradictions, we create real competitive advantage.” [P.85]

The microcomputer revolution of the 1980s provided tools to decentralize information processing-which helped improve local decision making-but the technology to support both local and enterprisewide information sharing and communication was inadequate. [P.93]

During the 1980s and 1990s, the solution adopted by many executives was to decentralize decision making to increasingly more focused and autonomous profit centers or “self-managing teams.” In so doing, decisions could be made more quickly, but the cost of coordination and control increased and decisions made by local employees and teams often failed to consider the overall goals of the company. [P. 251]

Interne/working Technologies Are Decentralized
Largely due to their Defense Department heritage, which dictated that computer net- works contain no single points of failure, internetworks have no central traffic control point. Computers connected to the network do not need to be defined to a central control authority, as is the case with some networking technologies. [P. 434]

Decentralizing the management of development projects and IT dcvelopment professionals to business divisions can align the development of new IT applications more quickly and effectively with the needs of senior divisional management. Standardization

[P. 265]
Standardization and technology advances permit specialization by individual firms in value chains, resulting in economies of scale and higher service levels. [P.431]
Standardization of computing infrastructure also pays dividends by reducing the complexity and cost of maintaining a firm’s IT capabilities. Simplification

[P.216]
This ICT standardization and business process simplification would effectively facilitate the acquisition process and enable faster and smoother integration into the DSM organization. A key consequence of the carve-out stratcgy was the realization by the business units that standardization on the SAP enterprise system platform (e.g., work processes, data standards, reporting templates) was a critical step towards operational simplification and efficiency. [P.433]

A centralized policy-based approach to both virtual and physical resources also can further the simplification, standardization, consolidation, and integration of IT services in common use across businesses and regions. At the same time, the ability to easily reuse and reconfigure [T capabilities and assets provides a robust but agile infrastructure platform for rapid future business growth.

Consolidation
[P. 139]
In the global appliance industry, for instance, competitors including Electrolux, General Electric, and Whirlpool have been squeezed by the consolidation of retail channels (the decline of appliance specialty stores, for instance, and the rise of big-box retailers like Best Buy and Home Depot in the United States). Another example is travel agents, who depend on airlines as a key supplier. When the Internet allowed airlines to sell tickets directly to customers, this significantly increased their power to bargain down agents’ commissions.

Centralization
[P.433]
Similarly, centralization of data management ensures coordination and synchronization of consolidated or physically distributed databases, so that business users, regardless of their location, can access data as needed.
Value Chain

[P. 68]
A streamlined and integrated value chain helped eliminate redundancies, reduce cycle time, and achieve even greater efficiency and productivity.
