Of all of the engineering fields, I have to think that our field of automation has one of the fastest rates of change. Every day new processes, new technologies, new instruments, and new control techniques invade the market, and an automation engineer must constantly strive to stay abreast of the latest offerings or face becoming obsolete. To stay current, I find myself constantly reading technical articles so I can quickly evaluate the benefits and weaknesses of the latest entries and determine whether they might be useful to my company or my clients. Of course the sales and marketing departments of the various vendors know this, and they spend a lot of effort publishing articles to “help” engineers select their product over their competitor’s.
Concept: Staying technically current in the field of automation is a never-ending task. Attending ISA meetings and conferences, vendor expos, and industry group conventions is a start, but your best solution is maintaining a steady diet of articles to keep abreast of the latest trends and technology. While many articles provide excellent information on a wide variety of topics, many others are written with a particular product bias or marketing angle. The author’s description, position, or byline will often alert you as to which type of article you are reading.
Details: Sales and marketing departments often employ people whose sole purpose is to write articles that appear technical but are in fact specifically written to entice engineers to specify or purchase their products. Before you read any article, skip ahead to the author information at the end and determine who wrote the piece. Please note that this tip is NOT a global slight against technical articles written by vendor personnel. Many vendors employ the top experts in a particular field to design and develop their products. These people often write informative and unbiased technical publications that are invaluable sources of information. However, knowing the background of the author before reading a piece can help you be on the lookout for misleading statements or positions that seem to favor one product or technology to the exclusion of others.
Watch-Outs: Be particularly wary of technical publications/magazines that are sponsored by a single vendor. These publications rarely allow any disparaging comments about their product and will rarely mention a competing technology except to explain how their product is vastly superior. While these publications can be a good source of information about a single system, they tend to limit their focus to the company’s product line and ignore all others.
Insight: Look for job titles such as “Sales Director,” “Marketing Manager,” “Product Development Manager,” or the “President” or “Vice President” of a particular vendor. Such titles are a strong clue that the true purpose of the article might be more sales related than technical.
Rule of Thumb: Just because an article is written by the sales/marketing department does not mean it should automatically be ignored. However, if the piece IS written by the sales/marketing department, be on the lookout for a biased view of the product. Does the article mention a particular brand or technology exclusively? Does it offer pros and cons of the subject, or does it only mention advantages and benefits and never mention any negative aspects. These questions can help an engineer quickly determine if the article in question was sponsored by the marketing department.
