Question

When dealing with a waiting line problem in which the arrivals follow a poisson distribution, and the service times are either exponential or follow an arbitrary distribution with a known mean and standard deviation, list three ways in which the performance of a system can be improved. Discuss the advantage and disadvantage of each one.

Answer 1

The performance of a system can be improved by three ways are

1) Analysis of standard vs. actual performance: By analysing standard vs. actual performance, unexpected and avoidable variances can be identified and controlled. which help an organzation to improve its performance.

2) Customer Centricity: Organization should focus on the customers preferences and requirements to improve the organization performance.

3) Promote employees initiatives and contributions: at the time of work change and for finding best practices employees initiatives and contribution should be promoted to increase the organization performance.

Advantage:

Performance evaluations allow managers to help employees with service development. Performing an unbiased evaluation can point out where employees are excelling and the areas needing improvement. After the evaluation is completed, managers can develop plans with specific tasks to help employees develop in their service and meet goals that benefit system.

Disadvantage:

A disadvantage of performance evaluations is that the managers evaluating employees may show bias to certain employees, which may happen intentionally or unintentionally. one risk of using performance evaluations is that some managers unconsciously favor employees that possess similar characteristics as the manager. Bias causes managers to focus more on the personality and style of the employee instead of the actual achievements. This can result in good employees feeling slighted, which may cause tension in the workplace. Bias also affects the favorable employee because he may miss much-needed guidance to improve his performance.
