What Constitutes the Business Intelligence (BI) Stack?

The promise of business intelligence (BI) requires that executives, managers, and systems engineers consider carefully what constitutes a complete and effective enterprise BI stack. Paul Pambudi (2010) describes a full BI stack as shown below:


Note that the data sources for BI include enterprise resource planning (ERP) systems, client resource management (CRM) systems, human resource management (HRM) systems, and others. Raw data from these sources is extracted, transformed, and loaded (ETL) into a data warehouse for storage. From the data warehouse, data is translated into usable information via a semantics layer, which serves the information to business analysts seeking to produce actionable descriptive, predictive, and prescriptive BI that adds value to decision-making.

The above illustration provides an instructive starting point for discussing the processes by which enterprise BI is produced. I will be discussing each of the layers depicted above in greater detail in coming posts.

The Political Economy of Government Employee Unions

by Thomas J DiLorenzo © 2011 LewRockwell.com

The main reason why so many state and local governments are bankrupt, or on the verge of bankruptcy, is the combination of government-run monopolies and government-employee unions. Government-employee unions have vastly more power than do private-sector unions because the entities they work for are typically monopolies.

Prof Thomas J DiLorenzo (1954- )

When the employees of a grocery store, for example, go on strike and shut down the store, consumers can simply shop elsewhere, and the grocery-store management is perfectly free to hire replacement workers. In contrast, when a city teachers' or garbage-truck drivers' union goes on strike, there is no school and no garbage collection as long as the strike goes on. In addition, teachers' tenure (typically after two or three years in government schools) and civil-service regulations make it extremely costly if not virtually impossible to hire replacement workers.

Thus, when government bureaucrats go on strike they have the ability to completely shut down the entire "industry" they "work" in indefinitely. The taxpayers will complain bitterly about the absence of schools and garbage collection, forcing the mayor, governor, or city councillors to quickly cave in to the union's demands to avoid risking the loss of their own jobs due to voter dissatisfaction. This process is the primary reason why, in general, the expenses of state and local governments have skyrocketed year in and year out, while the "production" of government employees declines.

For decades, researchers have noted that the more money that is spent per pupil in the government schools, the worse is the performance of the students. Similar outcomes are prevalent in all other areas of government "service." As Milton Friedman once wrote, government bureaucracies – especially unionized ones – are like economic black holes where increased "inputs" lead to declining "outputs." The more that is spent on government schools, the less educated are the students. The more that is spent on welfare, the more poverty there is, and so on. This of course is the exact opposite of normal economic life in the private sector, where increased inputs lead to more products and services, not fewer.

Thirty years ago, the economist Sharon Smith was publishing research showing that government employees were paid as much as 40 percent more than comparable private-sector employees. If anything, that wage premium has likely increased.

The enormous power of government-employee unions effectively transfers the power to tax from voters to the unions. Because government-employee unions can so easily force elected officials to raise taxes to meet their "demands," it is they, not the voters, who control the rate of taxation within a political jurisdiction. They are the beneficiaries of a particular form of taxation without representation (not that taxation with representation is much better). This is why some states have laws prohibiting strikes by government-employee unions. (The unions often strike anyway.)

Politicians are caught in a political bind by government-employee unions: if they cave in to their wage demands and raise taxes to finance them, then they increase the chances of being kicked out of office themselves in the next election. The "solution" to this dilemma has been to offer government-employee unions moderate wage increases but spectacular pension promises. This allows politicians to pander to the unions but defer the costs to the future, long after the panderers are retired from politics.

As taxpayers in California, Wisconsin, Indiana, and many other states are realizing, the future has arrived. The Wall Street Journal reports that state and local governments in the United States currently have $3.5 trillion in unfunded pension liabilities. They must either raise taxes dramatically to fund these liabilities, as some have already done, or drastically cut back or eliminate government-employee pensions.

Government-employee unions are primarily interested in maximizing the profits of the union. Consequently, they use civil-service regulations as a tool to protect the job of every last government bureaucrat, no matter how incompetent or irresponsible he or she is. Fewer employed bureaucrats means fewer union dues are being paid. Thus, it is almost guaranteed that government-employee unions will challenge in court the attempted dismissal of all bureaucrats save the occasional ones who are accused of actual criminal behavior. This means that firing an incompetent government school teacher, for example, can take months, or years, of legal wrangling.

Politicians discovered long ago that the most convenient response to this dilemma is to actually reward the incompetent bureaucrat with an administrative job that he or she will gladly accept, along with its higher pay and perks. That solves the problem of parents who complain that their children's math teacher cannot do math, while eliminating the possibility of a lawsuit by the union. This is why government-school administrative offices are bloated bureaucratic monstrosities filled with teachers who can't teach and are given the responsibilities of "administering" the entire school system instead. No private-sector school could survive with such a perverse policy.

Government-employee unions are also champions of "featherbedding" – the union practice of forcing employers to hire more than the number of people necessary to do the job. If this occurs in the private sector, the higher wage costs will make the firm less competitive and less profitable. It may even go bankrupt, as the heavily unionized American steel, automobile, and textile industries learned decades ago.

No such thing happens in government, where there are no profit-and-loss statements, in an accounting sense, and most agencies are monopolies anyway. Featherbedding in the government sector is viewed as a benefit to both politicians and unions – but certainly not to taxpayers. The unions collect more union dues with more government employees, while the politicians get to hand out more patronage jobs. Each patronage job is usually worth two or more votes, since the government employee can always be counted on to get at least one family member or close friend to vote for the politician who gave him the job. This is why, in the vast literature showing the superior efficiency of private versus government enterprises, government almost always has higher labor costs for the same functions.

Every government-employee union is a political machine that lobbies relentlessly for higher taxes, increased government spending, more featherbedding, and more pension promises – while demonizing hesitant taxpayers as uncaring enemies of children, the elderly, and the poor (who are purportedly "served" by the government bureaucrats the unions represent).

It is the old socialist trick that Frédéric Bastiat wrote about in his famous essay, The Law: The unions view advocates of school privatization, not as legitimate critics of a failed system, but as haters of children. And the unions treat critics of the welfare state, not as persons concerned with the destruction of the work ethic and of the family that has been caused by the welfare state, but as enemies of the poor.

This charade is over. American taxpayers finally seem to be aware that they are the servants, not the masters, of government at all levels. Government-employee unions have played a key role in causing bankruptcy in most American states, and their pleas for more bailouts financed by endless tax increases are finally ringing hollow.

On “Macroprudential Oversight”

Economists must sometimes scrutinize political rhetoric and terms that allude to well-understood economic concepts, albeit with "spin." For example, the terminology of "too big to fail" is widely used by political commentators as justification for an expansion of regulatory controls over the financial services industry (for more about the meaning of "too big to fail," visit my related post entitled, Too Big to Fail, or Just Too Big?).


Lo and behold, we are now witnessing the arrival of a new political rhetoric that takes the false concept of "too big to fail" to the next level. This new terminology is encapsulated by the notion of "macroprudential oversight," which Dr Ben Bernanke, Chairman of the Federal Reserve Board, describes as follows:
Under our current system of safety-and-soundness regulation, supervisors often focus on the financial conditions of individual institutions in isolation. An alternative approach, which has been called system wide or macroprudential oversight [italics added], would broaden the mandate of regulators and supervisors to encompass consideration of potential systemic risks and weaknesses as well.
For the record, the terminology of “macroprudential oversight” is not found in the standard macroeconomics lexicon (and neither is the phrase, “too big to fail”). Moreover, I fear the public is being bamboozled into believing these concepts carry clear economic meanings, which is not the case. From where I sit, the quasi-economic notions of "too big to fail" and "macroprudential oversight" are experimental hypotheses at best. The public should be suspicious of claims that the Federal government has the regulatory know-how to institute "macroprudential oversight" of systemic risks and weaknesses within the US economy. I maintain that the more pragmatic approach for managing systemic risks within the financial services industry is to view firms that are "too big to fail," as also being "too big to keep around."

Fixing Higher Education

Prof Douglas C Bennett, President of Earlham College, has suggested four steps toward "fixing" higher education in America:
  1. Fix the broken financing of higher education.
  2. Strengthen the focus on assessment of learning outcomes.
  3. End intercollegiate athletics as we know it.
  4. Build a national open access digital library system.
Change is coming to higher education, and all of the changes proposed by Prof Bennett make complete sense to me as a professional educator. Follow the link below to learn more...

Welcome to the Surreal...

Once the unemployed exhaust their 99-weeks of unemployment benefits, their future becomes even bleaker -- consider the options:
  1. Live off charity from family and friends.
  2. Find a lower paying job and live hand-to-mouth.
  3. Steal a grocery cart, push it to a nearby city, and start a new life.
 
Welcome to the surreal -- I weep for those suffering in America…

Уединенье

Блажен, кто в отдаленной сени,
Вдали взыскательных невежд,
Дни делит меж трудов и лени,
Воспоминаний и надежд;
Кому судьба друзей послала,
Кто скрыт, по милости творца,
От усыпителя глупца,
От пробудителя нахала.

~ Александр Пушкин

The Only Game Software on My Computer…

For well over a decade, Chessmaster (current version 11) has been the chess software program that has traveled with me on my laptop. However, today marks my transition to Fritz (version 12). While Fritz costs significantly more than Chessmaster, Fritz's extensive playing features make Fritz a better fit for me as a chess hobbiest (who plays to win). I suspect that most veteran chess enthusiasts would agree.

In particular, I like the "friend" mode in Fritz, which tailors the game play to the demonstrated skill level of the human player. Also, the new layout in the current version of Fritz includes ribbon features, which are emerging as the de facto standard for Windows programs since their introduction by Microsoft in Office 2007.


For those wondering, Fritz is the only game software on my computer. I play chess almost daily, so do not be surprised to a chess board on my computer screen from time to time if you are looking over my shoulder...

US Education & Training Outlays 1962-2009

One of the key provisions of Pres Obama's recently released budget proposal is increased Federal spending for education and training. The following charts are based on data obtained from the Office of Management and Budget (OMG):




Note that while the total Federal budget for education and training has been trending upwards since 1962, outlays as percent of the total Federal budget and gross domestic product (GDP) have been trending downwards. In other words, Federal spending for education and training has been declining as a percent of the total Federal budget and GDP since 1962.

If innovation and growth are fundamental to reversing the economic fortunes of the US, then I suppose a case can be made for reallocating budget dollars into education and training as a percent of the total budget and GDP. However, exactly how education and training dollars might be used remains a separate issue for public debate.

My intuition tells me that expanded funding for the sciences and engineering may indeed by justified, which is emphatically not the same as pooring dollars into failing schools in the secondary school system. The fact is that our nation has never truly targeted scarce education and training resources based on the specific needs of industry. Moreover, reallocation of education and training dollars between the defense and non-defense sectors may be justified. Indeed, reallocating education and training dollars within the existing budget may be a prerequisite to increased funding in general.

To the extent that increased Federal spending in education and training can be targeted to the sciences and engineering, I vote yea. However, if increased Federal spending in education and training means pooring scarce dollars indiscriminantly into the nation's secondary school system, then my vote is nea.
