Organizational Relationships & Extemporary Organizational Performance Essay

Organizational Relationships & Extemporary Organizational Performance Essay.

This assignment asks you to consider a current or past coworker who has low levels of either job performance, organizational commitment, or both. You are asked to draw on concepts from the course to explain exactly why this coworker is so ineffective, and how you and his/her supervisors might react, given that knowledge. The paper should be at least 750 words in length (all inclusive). More details are provided later in the syllabus. Details on Worst Coworker Paper Your paper can focus on either a current coworker or a past coworker. The coworker should be a real person, as opposed to an amalgam of multiple individuals. Moreover, some portions of the paper work better if the coworker is of a similar hierarchical level to you—as opposed to a boss or a supervisor. The paper should include the following three sections: 1. Background – Describe the coworker. Give enough detail that it’s clear why you feel the way you do about this person, with enough richness that the section “brings the person to life” for the reader. Resist the urge to provide irrelevant detail and feel free to omit or disguise any details that might be sensitive in nature. [about 125 words] 
2. Explanations – Drawing on concepts and theories from textbook, provide an explanation of why, in your estimation, this employee has low levels of job performance and/or organizational commitment. [about 500 words] 
3. Recommendations – Flowing out of the concepts and theories discussed in the previous section, describe what the top managers or leaders in the company could do, very specifically, to improve the performance and/or commitment of your coworker. Then describe what you, personally, could do to make this coworker more effective. Finally, answer the following questions: Is this employee a “problem that cannot be fixed” to some extent? If so, describe what the top managers or leaders in the company could do to avoid similar problems in the future. [about 125 words] 
Beyond the parameters above, please bring your own self-expression, initiative, and creativity to the content and style of the paper. 80% of the paper grade will revolve around content issues, with 20% revolving around writing style issues. In general, your paper should follow these formatting guidelines: minimum 750 words, double-spaced, single-sided, 12 point Times New Roman font, 1 inch margins, with no grammar or spelling errors. Papers that deviate from the general formatting will be downgraded. This policy is strictly enforced.You need this book for this:Organizational Behavior: A Practical, Problem-Solving Approach3rd Edition

Part I:Complete “Choosing the Board: Charting the Course with Competing Priorities (pg #241)” exercise. Rank them from highest to lowest.Explain why you made your rankings. List their diversity characteristics and how that impacted your ranking. Regardless of which four nominees are appointed, replacing one-third of the Board members all at once will mean a radical change for this board. This is a source of concern for the Board members and a serious concern of the hospital CEO who deals frequently with the Board. What might be done to ease the transition for the Board itself and for the CEO?What patterns emerge in your choices? Were all of your choices the same on any dimension(s)?

  Respond to at least two of your classmates. As a member of a community of practice, help each other refine and clarify the patient-centered Practice Experience Project. Provide support and suggestions on the importance of the practice problem in improving patient outcomes. POST THAT IS TO BE RESPONDED TO IS AS FOLLOW: The patient-centered practice problem chosen for our practice setting is falls. According to the World Health Organization, falls are the second leading cause of unintentional deaths worldwide, with age being a significant factor. A fall is an occurrence in which a person comes in contact with the floor at any time, even if it is inadvertent or not (World Health Organization, 2021). If a patient slides down to the floor or their knees buckle and are assisted to the floor, it is still considered a fall in the healthcare setting. Therefore, any fall has to be reviewed and reported bringing attention to further preventing them from occurring.     Falls that occur in the hospice unit are integrated with the data of Mercy Regional Medical Center. In my patient setting, we are at a greater risk of falls due to the use of high-risk medications, increased altered mental status due to disease progression, oversized rooms that take longer to get to, and encouragement of independence. Based on information from the Power Business Intelligence or Power BI application, falls are still of concern. There is a high enough incidence rate in our hospital that placement of a new call light system has begun facility-wide to alert more staff of patient needs and reduce patient fall risk behavior. Currently, the number one factor contributing to falls is either elimination-related or ambulatory needs. Based on the information read, more falls occur between the times of 0700-1700. The data is contrary to what one might think, with more individuals available to help during the day versus night shift. Regardless of the amount of staff on hand, falls are still occurring regularly.      There are numerous possibilities to review in how to improve the patient experience and prevent falls. For example, analyzing a fall and whether or not the level of care deviated from what is safe. Was an equipment malfunction discovered, or are patients getting rescored after being given high-risk medications? These are just a few questions in thinking about ways to analyze potential safety improvements in inpatient care. Increasing staff awareness or implementing changes to reduce fall risk expresses a dedication and commitment to improving the patient experience and quality patient care.       After discussing the various possibilities for this practice problem with my clinical leader, fall risk was selected based on the extent of information available and the fact that it continues to be an area of need in quality improvement for patient care and safety. Falls are considered the most common adverse event in hospitals, with a range of 7000,000 to 1 million falls yearly. In addition, the Centers for Medicare and Medicaid Services discontinued reimbursement for hospital-related falls, thus causing more pressure on facilities to prevent the sentinel events due to financial burdens (LaLaurin
