Performance Appraisal Methods (Scenario)
Carly has just returned from a conference on performance appraisal methods. It was an interesting conference and it generally confirmed what Carly had suspected about her company's performance management system—it required some drastic revision! The company's current method is to have the immediate supervisor write out an evaluation of each individual employee. This method is time-consuming for the supervisors, and is as much a test of their writing skills as it is an evaluation of actual employee performance. Carly considered three alternative methods to replace the current system. The first method was one of the oldest and most popular performance appraisals. It involved listing a set of performance factors such as quantity of work, quality of work, level of cooperation, etc., and then rating each factor on an incremental scale. The second alternative method involved a system that focused on specific and measurable job behaviours. It required appraisers to rate employees according to numbered items which each represented actual job behaviours, rather than general descriptions or traits. The third alternative method was very results-oriented and was often used to evaluate managers and professional employees based on their accomplishment of specific goals that had been jointly established with their superiors.
-What is the second alternative method that Carly is considering?

Understand and calculate confidence intervals for population means and proportions.

Comprehend the impact of changing confidence levels on the width of confidence intervals.

Understand the influence of sample size and population standard deviation on the margin of error.

Differentiate between the use of standard normal and t-distributions for constructing confidence intervals.

Definitions:

Air-over-hydraulic Brakes

A braking system that uses air pressure to control the hydraulic fluid movement, thereby combining the advantages of both air and hydraulic braking systems.

Hydraulic Booster Assemblies

Components designed to enhance the efficiency of hydraulic systems by increasing the pressure or force applied within the system.

Quick Release Valves

Quick Release Valves are components in air braking systems that allow for rapid exhaust of air from the brake chambers, facilitating faster release of the brakes and reducing brake release time.

Combination Valve

Used in a hydraulic brake system, it contains the safety switch, metering, and proportioning valves in a single valve body and usually is located close to the master cylinder. Also may refer to other multiple function valves such as the service, emergency, relay valve (SERV) used on air brake systems.
