Głupota ma magiczną moc. W Polsce przybiera często formy kultu lub organizacyjne.Nasi rodzimi głupcy nie muszą popadać w kompleksy. Jak się zapewne Państwo domyślają, głupota jest nie tylko polską domeną. Jeśli ktoś ma wątpliwości polecam książkę, według której prowadzi się wykłady w niektórych amerykańskich uczelniach. Byłem zmuszony przeczytać kawałki tego bełkotu. Straszna rzecz. Amerykanie mają wśród siebie mnóstwo głupców. Dowodzi tego fakt, że pozycja ta jest czytana, wznawiana i używana w wykładach. Także "Głupcy wszystkich krajów łączcie się". Straszna broń przeciwko rozumowi. Na podstawie tej książki można udowodnić wszystko. Wygląda wiarygodnie.

Although
this book must be commended on the variety of topics and sub topics
covered, it is very badly researched. Some sections I doubt were even
researched at all, it seemed as if the author is just giving his opinion
on how he "thinks" things are, and in the majority of these cases, he
is at best only half right. My favorites are his lists like, Consists
of..., Divided into the following..., Main elements are... etc. Some of
these lists can only have been sucked out of his thumb, because they
certainly were not based on any thoroughly researched facts.
IS is actually based on some very simple concepts that have grown and developed into today's seemingly complicated IS infrastructure and not the black and white boxes that Stair tries fit things into. I doubt the authors have much practical experience of IT, because they don't know the difference between marketing concepts and real IT concepts. These are just "selling techniques guys" not IS principles!
I would say that this book is not written for novices, but by novices. If you don't know any better then I think you will enjoy this book, because it will fit in well with a novices false preconceptions of how Information systems work. If you come from a practical IT background of 10 years + like myself and have actually witnessed the development of some of these technologies, this is a scary read.
One last note, colleges and universities that use this book as a reference are simply displaying their absolute ignorance about the subject that they profess to teach.

As
a scientist and engineer I find some disturbingly stupid ideas
presented in this book. For example, their definition of productivity
on page 64: Productivity = (Output/Input) x 100% Output/Input makes no
sense. Saying productivty is 30 reports for 40 hours work makes sense.
Saying productivity is 75% means nothing. If you made the denominator
one week instead of 40 hours, the productivity would be 3000%. What
tremendous productivity gain and all I had to do was change hours to
weeks. Percentages ONLY make sense when the numerator and denominator
have the same units. What they are suggesting is stupid. By presenting
the productivity (improperly) as a percent, they've eliminated all the
useful information from the productivity value.
The authors really have no sense of how to present informative, useful statistics. Another example is Figure 3.8 on page 97, which purportedly shows the cost per megabyte of several different storage devices. They inconsistently choose the drive mechanism cost for some types and the storage media costs for others. For DAT tape and 3.5" diskettes they choose the media cost and for ZIP and JAZ drives you choose the drive cost. Why not use the cost of ZIP and JAZ media so that the table would present consistent, useful information? If this is typical of the rest of the book, I would be very doubtful of it presenting any useable rational information.
