The Highs And Lows Of Revenue Forecasting
[ Source: "University of California, San Diego" ]
January 2008-
This paper examines the political and institutional determinants of accuracy and bias in revenue forecasts using U.S. state revenue estimates, legally binding numbers that cap budgeted expenditures. While the state forecast errors of limited interest, the dataset has the unique advantage of containing cross-sectional as well as time series variation in fiscal institutions, forecasting arrangements and political circumstances while still being based on relatively comparable units. National revenue forecasts may move markets, but institutions ...
Sales Forecasting For New Business

January 2008-
Sales forecasting is the process of organizing and analyzing information in a way that makes it possible to estimate what one?s sales will be. This paper outlines simple methods of forecasting sales using easy to find data. Sales revenues from the same month in the previous year make a good base for predicting sales for that month in the succeeding year. Credible forecasts can come from those who have the actual customer contact. Get ...

Standardization and Modularity in Data Center Physical Infrastructure
[ Source: APC ]
October 2011-
Failure to adopt modular standardization as a design strategy for data center physical infrastructure (DCPI) is costly on all fronts: unnecessary expense, avoidable downtime, and lost business opportunity. Standardization and its close relative, modularity, create wide-ranging benefits in DCPI that streamline and simplify every process from initial planning to daily operation, with significant positive effects on all three major components of DCPI business value - availability, agility, and total cost of ownership.
Electrical Efficiency Modeling for Data Centers
[ Source: APC ]
October 2011-
Conventional models for estimating electrical efficiency of data centers are grossly inaccurate for real-world installations. Estimates of electrical losses are typically made by summing the inefficiencies of various electrical devices, such as power and cooling equipment. This paper shows that the values commonly used for estimating equipment inefficiency are quite inaccurate. A simple, more accurate efficiency model is described that provides a rational basis to identify and quantify waste in power and cooling equipment.
Rack Powering Options for High Density
[ Source: APC ]
October 2011-
Alternatives for providing electrical power to high density racks in Data Centers and Network Rooms are explained and compared. Issues addressed include quantity of feeds, single-phase vs. three-phase, number and location of circuit breakers, overload, selection of plug types, selection of voltage, redundancy, and loss of redundancy. The need for the rack power system to adapt to changing requirements is identified and quantified. Guidelines are defined for rack power systems that can reliably deliver power ...
Guidelines for Specification of Data Center Criticality/Tier Levels
[ Source: APC ]
October 2011-
A framework for benchmarking a future data center's operational performance is essential for effective planning and decision making. Currently available criticality or tier methods do not provide defensible specifications for validating data center performance. An appropriate specification for data center criticality should provide unambiguous defensible language for the design and installation of a data center. This paper analyzes and compares existing tier methods, describes how to choose a criticality level, and proposes a defensible data ...
Strategies for Deploying Blade Servers in Existing Data
[ Source: APC ]
October 2011-
When blade servers are densely packed, they can exceed the power and cooling capacities of almost all traditional data centers. This paper explains how to evaluate the options and select the best power and cooling approach for a successful and predictable blade deployment.
Deploying High-Density Pods in a Low-Density Data Center
[ Source: APC ]
October 2011-
Simple and rapid deployment of self-contained, high-density pods within an existing or new low-density data center is possible with today's power and cooling technology. The independence of these high-density pods allow for predictable and reliable operation of high-density equipment without a negative impact on the performance of existing low-density power and cooling infrastructure. A side benefit is that these high-density pods operate at much higher electrical efficiency than conventional designs. Guidance on planning design, implementation, ...
Analytics: See the Opportunity - But Don't Ignore the Pitfalls Along the Way
[ Source: Accenture ]
January 2008-
This intelligent shopping cart already exists - though up to now it has been pushed round an Accenture research laboratory near Nice rather than the local supermarket. But this technology will eventually come to a retail outlet. And when it does, it will work by applying sophisticated real-time analytics to business intelligence drawn from accurate, timely and accessible transaction data. Anyone who doubts that analytics can drive high performance should look no further than a ...
