　　While we were taught from a young age that efficiency means multi-tasking,certain projects should be completed one at a time. Such practice ensures thequality of the final product and prevents from one having to redo certain partsof a long process. It also ensures the safety of those who will ultimately bethe users of the final product.

　　A person has a limited attention span, and a sole stress of efficiencyoften results in a compromise of quality. In projects that are highly detailedand require a lot of careful attention, a person must devote his full attentionto the task in order to not make any careless mistakes. Take, for example, abiology project involving the genetic engineering of a human cell line. A lot ofinitial planning is involved in selecting the right cells suitable for growingin a laboratory and capable of modification. The cells must then be carefullymonitored in a controlled environment to keep them alive. The genes to bealtered are analyzed before there are delivered in a viral vector to the desiredcells. All of steps toward achieving the final product are laboriously plannedout and executed. Any small mishaps along the way can easily force the scientistto start the process all over again and waste months of previous work.

　　Some projects are assigned with specific instructions for those involved tonot take on any other projects. Such projects often involve products that willaffect the safety of a large number of individuals. In the field ofarchitectural design, a public structure to be used by thousands, even millions,of people every day will require that the initial project be carried out withcare. The Tacoma Narrows Bridge was a public infrastructure completed in 1950along the Puget Sound that was considered a monumental feat of engineering inits day. The twin suspension bridge, spanning 5,400 feet, took years of planningand construction by teams of architects, engineers, and construction workers.However, because the Department of Pacific Northwest Transportation was takingon several projects at the time and couldn’t simply focus on the bridge, thegroup of engineers failed to take the aerodynamics of the bridge intoconsideration during the design process. The gusts of wind along the TacomaNarrows brought the structure to a collapse within months of the bridge’sopening, resulting in a catastrophe that is still remembered to this day as aclassic example of failure of engineering.

　　As the two examples show, the projects of certain highly skilledprofessions require careful attention to detail and must be completed one at atime. Trying to couple several projects simultaneously will only result in onehaving to redo a lot of work due to careless errors or worse, a devastating lossof lives.
