How much update does a Manager need With Programming , Web and Technology Issues?
Alireza Ebrahimi, State University of New York,
College at Old Westbury, USA
Abstract
How necessary is for a manager to be kept up to date with programming, web and technology issues? This may lead to a controversial debate.
How much a manger needs to be acquainted with area of information technology? Would these skills enhance the business growth, decision making,
strategy and problem solving? There is no doubt how information technology is essential, to the lively hood of the business world as oxygen is crucial to
the good health. What is the role of the manger? Managers as the heart of the business, with authority, knowledge, personal are responsible for plans, processes, policies, production, progress, place, price, people and many more. Information technology consist of two major components besides people which are hardware and software. The first computer hardware UNIVAC for business applications was launched in the 1950's with the main memory consisting of thousand words, and the processor speed of 2.25 megahertz with addition time of half second. The size of UNIVAC complete system was 350 square feet floor size. However, there is a theory that hardware can be replaced by software. The cost of software in comparison to the cost of hardware is extremely high and to duplicate software there is no effort, to duplicate hardware it's the same process.
It is the programs (software) that drive technology, the web page presents the
business enterprise to everyone. In the heart of every business there also are managers
responsible for keeping the records of performance, and using the records to promote efficiency,
discipline, and to get the job done. Today’s in-depth involvement of technology in the
marketplace has created a strong correlation between IT and managers. Over time, the bond
between a manager and IT is becoming stronger, signaling the need for more interaction and
understanding of both technical capabilities and business goals on the part of managers.
This paper posits that managers need to know more about information technology and
actively participate in the IT decision-making team. Furthermore, it suggests how managers can
have incrementally to acquire some elementary knowledge of programming issues, what shows
on the web, what is behind the web (source code), and what is placed on the server (database). In
a dynamic market where changes are made in nanoseconds. It is rewarding and may soon become
almost mandatory that a multi-talented manager will have to deal with change, to add or supervise
addition of pragmatic programming, and web update the web in order to be competitive. Key to
the process is the increasing communication and interaction between managers and programmers.
The benefit of understanding the elementary steps of programming and web technology is that it
will allow a manager to play a larger role in communicating and delegating responsibility with
confidence, and competence thus leading to cost reduction and better short- and long-term risk
management.

Programming Argument
In 1982, Robert Benjamin forecasted the state of IT in the year of 1990 stating that all
aspects of software will improve steadily, and the demand for software will be so great as to
appear infinite (Benjamin,1992). Now, nearly fifteen years later, we are experiencing the
fulfillment of these critical IT predictions, and the far more fundamental knowledge and
coordination of managers and the programmers they must direct.
Why is it crucial for a manager to keep up to date with programming issues and web
technology? One may assumes it is not part of a manager’s job description since programming is
associated with complex theories, mathematics, and gibberish code. Furthermore many also
assume there are mathematical formulas and theoretical concepts are involved in creating a
webpage (front end) or in a web server program (back end)? However the technology and its
programming have become less cumbersome than a decade ago, the problems can be easily
worked around by some explanation. We do not suggest that managers become programmers
who know details of syntax and semantic jargon of each programming language construct.
Rather they should become aware of the fundamental changes in programming and be able to
identify simple programming concepts such as input/output, decision-making, repetition, and file
handling. Managers need to be updated, to identify new simple concept of how to use
programming, communicate with programmers employed by their corporations and how to take
advantage of web technology. Similarly the programmers and web page specialists need to have
a through idea of the purpose production and
Modus vivendi of the company. Furthermore, amanager may be able to visualize a concept as to how it is used or should be used.
According to the U.S. Bureau of Labor Statistics, there are roughly 100 million
information users in the U.S. More interestingly, Sutcliffeis estimates that by 2005 in the U.S.
alone, there would be 55 million end-user developers in addition to 2.75 million professional
software developers. From the above estimate, one can conclude that one out of five people in
the U.S. population (295 million) has to deal with programming issues and write some sort of
program. Sutcliffe and Mehandjiev describe that End-user development is about taking control -
not only of personalizing computer applications (end-user computing) and writing programs, but
of designing new computer-based applications without ever seeing the underlying program code
