  • Management Question

    Appraisal Tool

    The effective evaluation of employee performance depends, to a certain degree, on the tool that is utilized. Based on that statement, in this Critical Thinking Assignment students will create a one-page Performance Management Form that can be used in an organization. To accomplish this task, complete the following:

    1. Choose any organization in Saudi Arabia that you are familiar with, either one you have been employed with or have studied/researched.
    2. Choose an assessment template that you find beneficial/advantageous (note: typing assessment or evaluation format into Google will bring hundreds of different templates for you to choose). Students can also use one utilized in their current/previous workplace, or one they are familiar with.
    3. Using that template as a guide, create your own assessment tool you would propose to evaluate any employee/position in that organization (for instance, you may choose to evaluate an employee in finance). Be clear about:
    • The assessment/evaluation criteria important in your review.
    • The rating categories (e.g., superior, meets expectations, etc.)
    • An appropriate mix/combination of check-box assessment criteria and short answers.
    1. Please post the assessment template you utilized as a guide along with your own completed assessment tool.

    Your form should meet the following structural requirements:

    • 2 pages in length, maximum
    • No need for in-text citations.
    • The assessment tool must be your own work, though you may follow the template/outline of those found via Google.

    You are strongly encouraged to submit all assignments to the Turnitin Originality Check prior to submitting them to your instructor for grading. If you are unsure how to submit an assignment to the Originality Check tool, review the Turnitin Originality Check Student Guide.

    Be sure to support any statement made in your form, and cite any statement and/or words/phrases that you are utilizing from other sources.

  • Homework 4 – Learning from failures in the interior environm…

    Review the facts described in the video below, do your own research about fires in the built environment, and answer the questions related to how the interior built environment and engineering ethics affect people’s live

    FIRST: Watch this video about a

    NEXT: Review this list of and the ASCE Code of Ethics discussed in class.

    THEN: Post your answers to the following three questions (200-250 words for each answer).

    1. Physical/Build Environment: The tragedy in Brazil happened in 2013 and the international community should have learned from it to avoid additional accidents. Compare and contrast the fire in Brazil with the one that happened in Switzerland in the Le Constellation bar in Crans-Montana on January, 1st 2026 by identifying three distinct elements of the interior built environment which contributed to both tragedies.

    2. Human Factors and culture of the location at the time of the fires: Identify and explain two distinct elements which might have been present in both tragedies related to the management/ownership of the clubs and how the decisions made by the owners of these venues (the acceptable culture of the local construction industry) might have contributed to these tragedies.

    3. Ethics and Professional Responsibility: Using the , briefly explain two duties of engineers and related canons (as described in the code of ethics) that were violated in these cases and how they were violated and ultimately contributed to these tragedies. (Please remember that the canons must be spelled out, points will be deducted from the answer if they are only mentioned by number.)
