Answer three for big thumbs up

In the second half of this term, we discussed topics such as quality, simulation \& queues, the importance of keeping customers occupied and informed when they are in waiting lines, different types of queue disciplines such as FIFO \& LIFO, etc. This question relates to some content from Weeks 5 \& 6 of this term. Identify the true statement by selecting one (best) choice. a. A manager responsible for queue management should consider the psychological aspect of customers in the queue. For instance, engaging customers in activities or providing updates on their estimated wait time can be effective strategies. b. Queues can manifest unexpectedly and vanish abruptly, often defying logical explanations. c. There is a positive correlation between good quality and profitability. d. When you navigate through a series of web pages and subsequently retrace your steps using the 'Back' icon, you are operating a LIFO (Last In, First Out) queue. e. All of the statements above (i.e., a, b, c, and d are true). Which of the following is true? In a two-dimensional activity diagram, if one axis or dimension denotes the outcome, then the other dimension or axis must denote the probability of the outcomes. No matter who tosses it, there is only one way to toss a coin. So, determining the outcome of a toin coss as Heads or Tails would be an example of a deterministic process. According to the H.E.A.R.T. guidelines associated with a good quality culture: a manager must never allow employees to fix "poor quality" related problems as they occur. They should always wait for a third-party quality consultant to give the approval, even if the error can be easily fixed by the employee. In the past 200 years, U.S. has witnessed significant shifts in labor force - first from services to agriculture, and then from agriculture to manufacturing in that order. Identify the true statement. a. The activities encompassed in Porter's Value Chain model include the threat of new entrants, and the threat of substitutes. b. Within a manufacturing organization, the exchange of information about production completion between Employee A in operations unit and Employee B in the outbound logistics unit would be an illuminating instance of an external value chain linkage.. c. Postponing the start times of activities in a critical path of a project flow diagram will not result in project delays. d. Participating in a live Zoom meeting and actively engaging in it represents an instance of synchronous communication, whereas receiving a chat on Slack and responding to it after two days represents an example of asynchronous communication. e. a and d are true
