Assess the Importance of Project Scope Planning for a Project of Your Choosing

 

For this week, you will need to research and identify a project of your choosing (examples – house painting, renovation of a kitchen, new business IT system, etc.) that will be the central example in the completion of this and future assignments throughout this course. The first step in your process once a project has been selected will be the development of a scope statement. The scope statement describes the project and outlines project goals that need to be met in order to be successful.

 

Once a project has been identified you will be required to build scope statement that will include the objective of the project, goals, a clear description of the project and any related tasks that need to be accomplished. Ensure the project selected is easily accessible to you; if you have the opportunity, converse with a real-world project manager regarding your project, ideas, and actions.

In a paper, explain and assess what project scope planning is as a process and how you plan to implement the process for your chosen project. Include in your explanation the scope statement, consideration of Life-Cycle Phases and participant roles. Indicate why you believe plans fail and justify the importance of a project charter in the project scope planning process.

Support your paper with a minimum of three (3) external resources. In addition to these specified resources, other appropriate scholarly resources, including older articles, may be included.

Length: 6-7 pages not including title and reference pages

Your paper should demonstrate thoughtful consideration of the ideas and concepts presented in the course and provide new thoughts and insights relating directly to this topic. Your response should reflect scholarly writing and current APA standards

What does it mean to succeed in school?

Personal Expository Essay

HI ,i want a papaer for my English Composition class. Here is the topic for the eassy.

 

 

Topic for the Personal Expository Essay

How do we view “school”? What’s the role of school, and what does it mean to society? You’re in college taking what may be your first college-level course, so college and education more generally must be important to you. But what does it mean to you? There are all kinds of schools; even college offers many different ways of learning. What does it mean to succeed in school? What does it mean to fail?

Our first essay will be an exposition based on your personal experience with any and all kinds of education. You’ll need a clear thesis sentence and strong supporting details from your own experience or that of your family or friends. In this 3-4 page paper, you might follow a traditional, five-section format, but you don’t have to—and your goal for the course will be to go beyond that. You should mostly think about the purpose of your paper: why are you writing it, and what are you trying to show especially about the values people place on education?

 

In our class discussion, we’ll consider a number of educational topics such as recent trends in community college education and reasons why people attend college. Are there different reasons to go to college? Is one reason better than another? What should an education be, and how should schools be teaching? Your goal isn’t to answer these particular questions but instead to make a claim about education and learning and give strong support for your claim.

How will your understanding of the history of private security play a role in your communications with the UPD?

Security Management, origional work, 800 words

 

You are a newly promoted manager for a medium-sized, locally operated security company. The owner of the company recently elevated you to your new position to place you as a security director in a large hotel and convention center for which the security company recently received a contract to provide full 24-hour security services. The owner of the security company advises you that the hotel and convention center were funded by private as well as university funding, and the structure is located on the campus of a large university in your town.

 

Because of this unique ownership situation, there are three parties with interests in security matters inside the facility and in the surrounding property: the management company; the university; and now, your security organization. You are also advised by the owner that you will be working closely with campus law enforcement who will provide security primarily on an as-needed basis for the facility and the outer perimeter of the building. Because this is a unique situation that your security manager has not previously faced, he has asked you to come up with a management plan and present it to him within the next week. Your manager did provide you with a list of areas toward which he felt you needed to focus your primary efforts.

 

Assignment Guidelines

 

Hiring

 

  • Provide a document of 300 words detailing the hiring process that you will use to select personnel for your facility.
    • You will not utilize the normal hiring process of your company; instead, you will hire people directly for that facility as per the management agreement.
  • In this document, you will advise on the following:
    • How you will recruit personnel
    • The standards and qualifications that individuals should meet
    • Any pre-employment background investigations, screening, or testing that will be done
    • Any important legal issues in the recruitment and selection process that you need to be concerned with

      Shift Scheduling

 

  • To provide 24-hour coverage for the facility, you have initially been provided with the authority to hire 12 security officers.
  • In your response, you will devise an example of 200 words of a schedule that you can utilize to provide 24-hour coverage for the facility.
  • The schedule can be completed as a Microsoft Word table or any other type of format, with the days and hours of coverage and the number of officers per shift given in the example.
  • By contract, you are required to have at least 2 people on the property between the hours of 8 a.m. and 5 p.m. Beyond that requirement, it is left up to you to cover the remaining shifts.
  • Answer the following question:
    • What are some of the employee and legal considerations that you need to consider before you schedule your officers?
      • Given a choice of an 8-hour shift, a 10-hour shift, or a 12-hour shift, which would be most beneficial to you to provide the coverage needed at the facility?

        Relations With University Police and Other Challenges

 

  • Relations between law enforcement and security can sometimes be strained. This is primarily because the goals of each entity are not necessarily identical.
  • In 300 words, provide your manager with a plan for how you will engage the University Police Department (UPD) to facilitate your relationship with the department and its officers.
  • This is going to require that you meet on a regular basis with the UPD to ensure that things are running smoothly.

    • How will your understanding of the history of private security play a role in your communications with the UPD?
    • As a supervisor, how do you see your role in promoting this positive relationship?
    • What type of joint training programs do you see as being useful between your department and the UPD?
    • What are some of the other types of challenges that you foresee that might affect your relationship with the UPD? What steps will you take to negate or minimize these challenges?
