Our "improved" technology sucks up dollars like a vacuum cleaner, but never seems to increase what user-businesses earn from their customers. This indicates "foolish investments." Management engineering is an application of basic industrial engineering to the work of gaining performance through organizations. It provides a practical viewpoint based on profitability. There is a continuing cash flow from office-technology users into the pockets of technology providers. Such is the visible result, but it does not adequately describe this gluttonous monster. The real description is in our belief that our current Technology approach is good management. We are in a hostile situation where profits yield to technology demands. There is steadily increasing cost, without increase to income. This is what we see. The demonic damage is even greater, and is hidden from those who are under its influence. Now the quality and usefulness of information is also on the decline. The challenge is partly spiritual, an attitude that encourages modern managers to replace basic management with technology solutions. Weak management allows profits to bleed away. Management engineering provides the clarity of vision that promotes solution. We face a problem in management; so this is where the problem must be resolved. The effective solution is through putting general managers back in charge. This work demonstrates how to harness this demon by returning to recognized good-management practices. Then there is encouragement for turning the demon back into a profitable direction and applying the whip with a clear purpose. Under determined management, technology will again serve the business.With this level of change,there are also many opportunities for the technology-savvy entrepreneur.
