Macro-Environmental Factors

 A key tool utilized by strategic Human Resources professionals is known as a PEST analysis (political, economic, social, and technological). This tool provides a framework to think about over-arching macro-environmental factors. These factors impact the organization, the Human Resources Department and, ultimately, the employees. This acronym has recently been broadened to PESTLE to include legal and ecological (i.e., climate, weather) considerations. All six macro-environmental factors are clearly interrelated and important.

Discussion Board – APA – 300 Words – Due in 48 Hours – For Wizard Kim

Compensation is a controversial workplace topic. Throughout the years, specifically the past decade, average employee wages have not greatly risen. However, managerial and executive pay has steadily increased.

Despite current economic stability and low unemployment rates, U.S. businesses are constrained from raising employee salary and benefits due to low-wage foreign competition.  This week’s readings showcase a case study on pay compression at Envelop City and on how McDonalds uses praise (intrinsic factor) and individual incentive pay (extrinsic factor) to ensure satisfied and happy employees.

Discuss how an organization can motivate its employees to maintain/increase their productivity and performance without significantly increasing employees’ compensation.  Additionally, as a compensation consultant, how would you develop market value for positions within your organization? Propose a compensation plan to ensure that rewards (i.e., wages, benefits, and other compensation) match job duties, tasks, and responsibilities.

Answer the above using the question and answer (Q&A) format.  The Q&A format should include the original question along with your response. Within your post, support your responses with information from at least one peer-reviewed/scholarly source (not older than 3-5 years) from  CSU Global online library or the Internet, and provide the full citation at the end of your post. Use APA guidelines (at the CSU Global Writing Center )  to format your references. Your total word count must be at least 300 words excluding the original questions.

I need help with HRM/498T Strategic Human Resource Management And Emerging Issues Assignment week 2

I bid this out and didn’t receive the grade I was looking for, I can only afford $20, can you help me?

Powerpoint

The problem-solving model was first laid out by Helen Perlman. Her seminal 1957 book, Social Casework: A Problem-Solving Process, described the problem-solving model and the 4Ps. Since then, other scholars and practitioners have expanded the problem-solving model and problem-solving therapy. At the heart of problem-solving model and problem-solving therapy is helping clients identify the problem and the goal, generating options, evaluating the options, and then implementing the plan.

Because models are blueprints and are not necessarily theories, it is common to use a model and then identify a theory to drive the conceptualization of the client’s problem, assessment, and interventions. Take, for example, the article by Westefeld and Heckman-Stone (2003). Note how the authors use a problem-solving model as the blueprint in identifying the steps when working with clients who have experienced sexual assault. On top of the problem-solving model, the authors employed crisis theory, as this theory applies to the trauma of going through sexual assault. Observe how, starting on page 229, the authors incorporated crisis theory to their problem-solving model.

In this Final Case Assignment, using the same case study that you chose in Week 2, you will use the problem-solving model AND a theory from the host of different theoretical orientations you have used for the case study.

You will prepare a PowerPoint presentation consisting of 11 to 12 slides, and you will use the Personal Capture function of Kaltura to record both audio and video of yourself presenting your PowerPoint presentation.

To prepare:

  • Review and focus on the case study that you chose in Week 2.
  • Review the problem-solving model, focusing on the five steps of the problem-solving model formulated by D’Zurilla on page 388 in the textbook.
  • In addition, review this article listed in the Learning Resources: Westefeld, J. S., & Heckman-Stone, C. (2003). The integrated problem-solving model of crisis intervention: Overview and application. The Counseling Psychologist, 31(2), 221–239. https://doi-org.ezp.waldenulibrary.org/10.1177/0011000002250638

Strategy, Planning, and Selection

Scenario

Assume for this assignment that you are being highly considered for a director-level HR management position for a best-in-class national retailer. You are in the final phase of the interview process and must respond to the interview panel regarding specific questions and scenarios that will help them determine if you are a good fit for the new role. The company’s culture is centered on the effective development of strategy, plans, and selection criteria aimed at building and sustaining a competitive and profitable organization. It will be extremely important that you respond with a strategic mindset in order to convince the organization you are able to help them ensure the execution of the business strategy. 

Instructions

Write a six- to seven-page paper in which you do the following: 

  • Analyze and discuss different types of strategies (cost leadership, differentiation, and focus/niche) then select which one you would deem more appropriate for an “efficiency-minded” retail organization and explain your rationale. How would the selected strategy ultimately affect how HR does its job?
  • Examine the four approaches to job design or redesign and provide an example (not a definition) of each. Then, make a case to the interviewing panel on the importance of effective job design applications in supporting the overall strategic goals of the organization. 
  • Consider challenges and constraints associated in recruiting and identify and discuss at least two to three issues. What advice would you give to leaders to address your selected issues? Be specific. 
  • List and describe 2–3 candidate selection process ideas that might add value and overall effectiveness to the process. Example: 5 Tips for Designing an Effective Employee Selection System. Also, what problems should HR and management teams avoid during the selection process?
  • Use at least four quality academic resources in this assignment. Note: You may only use the resources listed in the Course Guide and those that are specifically provided by the professor.

Balanced Scorecard

You were introduced to the concept of accountability in Chapter 15. The Balanced Score Card was introduced in Chapter 17.  The Balanced Scorecard is a business tool that has grown in popularity.  It provides a quick overview of the several performance measures in several areas of the organization.  Some managers feel that whatever gets measured will get improved simply because it is getting additional attention.  As you will see in Chapter 17, however, not everyone agrees that the scorecard is an effective performance management tool.

Emma is on the fence as well.  She would like you to research the Balanced Scorecard concept and share your recommendations as to whether or not CM Tech should adopt the tool.

Your research paper for Emma should include the following key elements: 

  1. Provide an overview of the balanced scorecard that describes what the scorecard is and what a management team would hope to accomplish by using one. 
  2. Debate the tool:  Explain the advantages and disadvantages of using a Balanced Scorecard.
  3. Develop your recommendation to Emma as to whether or not CM Tech should adopt the Balanced Scorecard.  Be sure to fully support your recommendation with reasoning, examples, and research.

Your report should outline the key concepts in each area listed above and provide examples as appropriate.  Be sure your report is a minimum of 5 pages, includes an introduction and conclusion paragraph, title page, and references page.  The title and references pages do not count toward the total page count.

 RE: Week 4 DiscussionCOLLAPSE

Hello Class and Professor, 

In most organizations, formal training is an essential component of keeping up with new trends and technologies in the industry. However, training may not solve all performance and behavioral problems. Hence, an organization should conduct a training needs assessment before introducing training programs to assess whether training may solve a performance problem. Other than training, learning by experience may be an option. As such, evaluation of learning by doing or experience is essential in informing its effectiveness in complementing formal training. 

Describe an example of “learning by doing” that has helped you or a colleague to grow professionally.

After graduating from university with a bachelor in Statistics, Kelvin joined our local animal feeds manufacturing company as a data analyst. His university training was majorly mathematical and had nothing to do with animal health and nutrition. However, his new role required him to have insights into animal nutrition. He quickly got in touch with the production manager and was occasionally involved in the production team while formulating the food rations. With time, Kelvin developed the skills of accurately preparing feeds’ components such as proteins and minerals while retaining acceptable profit margins. Soon, Kelvin became an essential component of both the production and analytics teams. 

What did this experience teach that could not be taught through formal training?

Although the training was an option in learning animal nutrition, it would take time to cover all aspects. Still, the organization does not use all aspects of animal nutrition modules. Learning by doing was the most suitable learning method as it incorporates relevant theoretical and practical elements of animal nutrition. Nevertheless, training modules hardly existed at the organization to enhance the incorporation of animal health and data analytics. 

What part of the experience could have been learned through formal training? 

Animal health and nutrition training is available at the organization. Employees within the production team regularly participate in formal training relating to trends and new technologies in line with animal feed production. However, Kelvin’s case stood out, as it required integrating skills in feeds formulation, production, and data analytics. 

Should your organization create formal training to complement its hands-on learning activities? Why or why not?

Kelvin’s case depicts a situation where learning through experience may yield significant outcomes. However, it is rational to analyze such a situation in the context of the problem at hand. Organizations should also adopt formal training to complement learning by experience. Learning through experience enhances personal growth and competence aligning with new roles (Fernández-Aráoz et al. 4). Formal training improves collective responsibility for success among current employees and new teammates by sharing experiences, challenges, and insights (Stibitz 3). A blend of learning through experience and formal training enhances performance and employee outcomes.

Dear Professor Dibenedetto and Class

1. Describe an example of “learning by doing” that has helped you or a colleague grow professionally.

I am a long-life learner in all aspects of my life. I have developed a growth mindset. I have improved my life quality and work as observe people doing things that I will not ordinarily do well. One example that stands out in my pursuit of learning by doing is how to do proper workforce planning, which is a combination of HR concepts such as organization design, budgeting, and job pricing. These are competencies that involve knowledge in HR, finance and remuneration, and data analytics. I realized that I do not have a budget to hire an employee who is an expert in workforce planning, as it is a critical skill in the insurance business. Most actuaries do not want to work in HR but were keen to design a workforce tool. I approached our CEO, who agreed that he would second an actuary into HR to develop the tool. I used to watch him with the design and play with the tool until it was executed.

2. What part of the experience could have been learned through formal training?

There is no part in the learning process that I would say required formal training. I am already a seasoned excel spreadsheet practitioner; otherwise, I would have preferred formal training as a beginner. I still believe that 70/20/10 learning is still relevant, where 10% is about formal learning.

3. What did this experience teach that could not be taught through formal training?

I currently do all my annual workforce planning and reporting using the tool, and I have trained others in the team through action learning and are using the tool in all our 33 countries. We used the same tool during COVID-19 to schedule the workforce and understand who can work from home indefinitely (and only come as required), hybrid model, and tracking those on sick leave due to the pandemic. We are also using it to plan for the workforce plan during the recovery phase caused by the pandemic as we want headcount growth not to increase by 2% over the past three years. I would not gain a portfolio of diverse skills in reward, budgeting, and data analytics at the same time if it were not through action learning.

4. Should your organization create formal training to complement its hands-on learning activities? Why or why not? My organization has formal training programs supported by a learning management system. Our main challenge is that learning it is isolated from the day to day work requirements of employees. I believe learning on the job through the 70/20/10 action learning process should be the norm. Learning can be powerful if it is integrated into the daily workflow. As scholar Josh coined, “there is a new paradigm of learning in the flow of work.” The fourth industrial revolution tools such as AI, automation, podcasts, youtube has enabled an environment where lifelong learning is part of the economic imperative. For employees, research now shows that development opportunities have become the second most crucial factor in workplace satisfaction (after the nature of the work itself). In my view, the traditional corporate learning portal (the learning management system) is rarely used (other than for mandatory compliance training), and it often takes many clicks to find what you need. Learning, therefore, ends up being reduced to important-but-not-urgent matters.
