- Is an information system the same thing as a program or "app"?
I've been writing about Information Systems for over three decades, mostly to I.S. professionals, and I've spent in inordinate amount of time trying to clarify our terminology and concepts, as well as dispel basic misconceptions about systems. For example, there are those who believe an Information System is a computer. Sorry but, No, that is a piece of equipment, a tool used within a system. Then there are those who think it is a computer program or collection of programs like what you find on an iPhone. As an aside, the word "app" (for "application") is indicative of the sloppy thinking in the industry; an "application" of what? No, let's call a spade, a spade; they're not "apps," they're "programs," but I digress.
Perhaps the biggest misconception regarding Information Systems is that you cannot have one without a computer. Sorry, but this is simply not so. The day a company goes into business, large or small, is the day when its Information Systems are born. For example, companies need to routinely manage their finances, pay employees, manufacture products, process customer orders, manage assets and inventory, schedule deliveries, etc. This has been going on well before the advent of the computer. The only difference is systems were implemented by manual processes as opposed to computer automation.
Perhaps the best way to think of an Information System is as an orderly arrangement or grouping of processes dedicated to producing information to support the actions and decisions of a business. Hundreds of years ago, systems were implemented using logs, journals, ledgers, spreadsheets, and filing cabinets. Over time, equipment was introduced in the form of such things as cash registers, typewriters, adding machines, and tabulating equipment, all of which eventually gave way to the computer. Incidentally, there are many manual processes still in our companies serving critical business functions, much more than you might think, most of which are not properly documented.
When I teach a basic class in this subject, I ask the students to design a totally manual system just to overcome the handicap of thinking only in terms of computers. For those imbued in programming, this exercise represents an epiphany and teaches them to think outside the box. Suddenly they realize writing a program is only a small part of a much larger puzzle.
The reason people have trouble understanding the difference between systems and programs is actually quite simple; a program is much more tangible than a system. You can touch and feel a program, particularly its screens, reports and source code; but a system is much less tangible as you are talking about several business processes that operate routinely, and are implemented by people and technology that will come and go over time.
This brings up an interesting point, the basic business processes of a system (aka "sub-systems") are logical in nature and only change when information requirements change. They are implemented by manual procedures and computer programs that are physical in nature and change dynamically as technology changes, but the business process remains essentially the same. Consider this, for any company who has been implementing payroll for a number of years; Has the process of paying your employees really changed or was it the method of its implementation? If, years ago, you paid your employees on a weekly or monthly basis, you are probably still doing so. The only thing that has changed is physically how you have been doing it. Whereas you may have started out preparing payroll manually years ago, this was probably replaced by a commercial package to do the same thing, which has probably been updated or replaced several times; but your employees are still paid weekly or monthly aren't they?
Next time someone promises you a womb to the tomb Information System on a computer, remind them that the first on-line, real-time, interactive, data base system was double-entry bookkeeping which was developed by the merchants of Venice in 1200 A.D. .... and there wasn't a computer within miles of it.

I have been a Freemason for many years and I am still surprised by those people who believe the Masons have a secret agenda in terms of manipulating the country or stockpiling incredible amounts of wealth. Heck, we have trouble organizing a picnic. However, there is reasonable evidence to show Masons were involved with the founding of the country. For example, of the 56 men who signed the Declaration of Independence, 9 were Masons (16%), and of the 39 men who signed the U.S. Constitution 13 were Masons (33%). Of the 44 presidents we have had, 14 were Masons (32%) with the last one being Gerald Ford. Beyond this, few people outside of the fraternity truly understand the impact of Masonry in America.
Seeking the truth can be a delicate matter fraught with pitfalls. It may interfere with another's political agenda or personal gains. Besides, people do not necessarily want to know the truth. Most are quite comfortable hiding within their shell minding their own business, and not wanting to get involved with the outside world. Today, it is more important to be politically correct than seek the truth, something which may lead to a person being ostracized for possessing an inquisitive mind. I have run afoul of this on more than one occasion, not just in my consulting practice but in nonprofits as well. When I dare ask a question or point out an indiscretion, I am often accused of being a troublemaker. Such is the price you will likely pay. The questions though must be asked, and only a handful of people are willing to risk injury to their integrity, but they are desperate for finding the answer. One such person was Abraham Lincoln who wrestled with the question of slavery.
There is only one thing worse than incompetence, and that is accepting it. I began thinking about this over the holidays when I took an ocean cruise. I have taken many such cruises over the years and have traveled on many different lines, some better than others. The line and ship I took this year was new to me. It was a large ship with about 2,200 passengers and was a part of a well known shipping line. Our destination was the Western Caribbean where I hoped to relax and catch up on my reading. I graded the food on board as "fair" at best, but I was particularly appalled by the embarking and disembarking procedures on/off the ship. Our first port of call was in the Honduras where I had scheduled a round of golf. There was only one problem, I couldn't get off the ship.
People ask me why I seem to be "black and white" on so many issues. Two reasons come to mind: first, I learned early in school that you do not get credit for making a mistake. If this has changed, please let me know. Second, the nature of my work in the information systems world has taught me there are right ways of doing things, as well as wrong ways. I am also not embarrassed to admit, "I do not know," when I am unsure of myself, and will endeavor to find the answer. Failure to admit this is a sign of weakness, as is fabricating an excuse or leading someone down the wrong path.
I have heard a lot of women make the observation the art of baking is dying, that most young people no longer know how to make a loaf of bread, cookies, cakes or pies. There is nothing from "scratch" anymore. I also suspect roasting a chicken or turkey is on the decline. Frankly, I cannot think of anything simpler, but it has become commonplace to purchase roast turkey dinners from grocery stores like Publix and Kroger, as opposed to cooking it yourself. Traditional comfort foods are also disappearing, such as salisbury steak, beef tips and noodles, pork tenderloin, pot roast, chipped beef on toast (SOAS), flank steak, turkey tetrazini, pot pies, or chicken a la king. Soups, stews and chile are also disappearing in favor of canned substitutes. Likewise, fruits and vegetables are seldom cooked fresh, such as brussel sprouts, cauliflower, asparagus, broccoli, snowpeas, etc. As for me, I love stir fried vegetables, particularly in the summer time. Alas, not many people make it anymore, regardless how quickly it can be prepared.
Last month I was reading about a 21 year old New Jersey woman,
In the corporate world, when we join a company, we are normally presented with several documents from the Human Resources department which we are asked to sign. As a newcomer, you would be wise not to rush through this process and review each document carefully. If you have questions, ask. You do not want to be surprised if a problem arises during your employment or afterwards as an ex-employee.
An old friend in Versailles, Kentucky recently wrote to me. He is a High School math teacher who is tired of hearing the question from his students, "Why do I have to take this course? I will never use it." This, of course, is a common lament heard by teachers around the world but it seems to be growing in intensity. Students pose the question as they believe it will have no bearing on their lives, particularly due to technology.
It is not much of a secret American liberals are not proponents of Capitalism; they do not see it as fair and, instead, there should be a redistribution of the wealth, from the rich to the poor. It is also not much of a secret they abhor American exceptionalism; that we owe certain minorities of our country and the world an apology for our sense of Manifest Destiny. They also seem bent on eliminating God from our culture, steadfastly banning it from schools, government institutions, removing the Bible wherever possible, and censoring the clergy (see Houston). It is also no secret liberals want to replace the U.S. Constitution with something more modern and less restrictive in terms of rights. And finally, the latest twist is to undermine our jurisprudence system in order to allow thuggery to flourish and undermine the safety of the public. By doing so, they wish to radically change the American way of life and make it more dependent on government.
Not long ago I wrote on the three fundamental styles of management,
