Why are there economies of scale in queuing systems?
Queuing systems refer to the process of managing waiting lines in organizations. Economies of scale exist in queuing systems because the cost per customer decreases as the volume of customers increases. In other words, when more customers are served, the unit cost of service is reduced, resulting in a lower average cost of service.
What are the pros and cons of pooled-queue systems and separate-queue systems? Provide examples along with your opinion of the best option.
Pooled-queue systems refer to a queuing system in which all customers wait in a single line to be served by the next available server. Separate-queue systems, on the other hand, refer to
a queuing system in which each server has its own queue. The advantage of a pooled-queue system is that customers have a shorter wait time since they can be served by any available server. However, this system may result in some customers waiting longer than others if some of the servers take longer to serve their customers. The advantage of a separate-queue system is that
customers are served faster since each server is responsible for its own queue. However, this system may result in some queues being longer than others if some of the servers are more popular than others. In my opinion, a pooled-queue system is the better option since it reduces overall wait times for customers.
Provide an example of how variability can reduce capacity. Once compromised, how can capacity be restored?
Variability refers to the differences that may exist in customer arrival rates, service times,
and other factors that affect the waiting time of customers. Variability can reduce capacity since

it results in longer wait times for customers, which can lead to dissatisfaction and lower productivity. For example, if a bank experiences a sudden surge in customer arrivals, the variability of customer arrival rates can reduce the capacity of the bank to serve all customers in a timely manner. Once compromised, capacity can be restored by adding more resources or increasing the efficiency of existing resources. For example, a bank can increase its capacity by hiring more tellers or by implementing more efficient processes that reduce the time required to serve each customer.
Complex Projects
Consider the most complex project you’ve ever been involved in. Briefly describe the project, giving examples of the following as they pertain to the project.
The work breakdown structure
The work breakdown structure (WBS) refers to a hierarchical decomposition of a project into smaller, more manageable components. In the complex project I was involved in, the WBS was used to break down the project into smaller, more manageable components that could be assigned to different team members. For example, the WBS included tasks such as project planning, design, implementation, testing, and deployment.

Tasks refer to specific activities that need to be performed to complete a project. In the complex project I was involved in, some of the tasks included creating a project plan, designing the project, developing code, testing the code, and deploying the project.
Subtasks
Subtasks refer to smaller activities that need to be completed to achieve a larger task. In the complex project I was involved in, some of the subtasks included creating a list of project requirements, selecting a design approach, coding individual components, and testing individual components.
Work package
A work package refers to the smallest unit of work that can be assigned to a team member. In the complex project I was involved in, each work package was assigned to a specific team member who was responsible for completing it within a given timeframe.
Were you on the critical path? Additionally, explain the role the project manager played in managing the project’s success or failure. Include an example.
The critical path refers to the sequence of tasks that must be completed on time for the project to be completed within the
