Waiting lines have become one of the basic problems in many organizations despite the fact that all projects are properly managed and examined. Even if service systems are underloaded, the chances of facing a waiting line challenge are high. Using the example of a fast-food restaurant business, Stevenson shows that although there is the capacity to handle an average number of orders, waiting lines emerge.
The author underlines the word “average” in this discussion and explains that this happens because of average unpredictability and generality. In my personal experience, I observed several symbolic waiting lines in completing my homework. Although I try to plan each day and consider my qualities and skill, the type of assignment and the length of preparation vary.
Even the intervals between the assignment are never the same, which explains the inability to do all tasks beforehand, and additional time is needed to complete everything. As a result, I can be overloaded with tasks during one period or have nothing during another period. The waiting lines should be determined through demand-capability fluctuations that are unpredictable and usually temporary.
