Project buffers are used to provide cushion for the project and
the individual task that make up the project. The buffers provide
extra time, so the project can remain on schedule even with
minor delays. CCPM uses four different methods for working
with buffers. The four methods are 50% of the difference,
square off the sum of the squares, bias plus SSQ, Monte Carlo
analysis (Leach, 2014). Each method has strengths and
weaknesses, but when used properly they can be beneficial to a
project.
The first method or 50% of the difference estimates buffers by
calculating the difference between low-risk and the average task
and dividing that in half. This is a simple method, but
sometimes causes buffers to be too large. The second method or
square of the sum of the squares also uses the difference
between low-risk and the mean, but it uses the square root of
the difference squared. This method takes into account
unexpected variation, but can create undersized buffer. The
third method or bias plus SSQ combine the first two methods.
The fourth and final method or Monte Carlo analysis is the most
complicated, but encompasses many of the other advantages of
the previous method (Leach, 2014).
Each method has its advantages, but I would suggest using
method 3, bias plus SSQ. This method provides a simple
platform that offers a high level of control over accuracy.

Top of Form
Class,
The “less is more” more approach is interesting to me because I
have grown up in a military culture where if it is not on paper
then it won’t happen or it didn’t happen. Leach did discuss

3. where some project managers are very proud of having very
high number of tasks associated with the project because they
have “thought of everything”. However, as a project manager
you are not as worried with the individual tasks that it takes to
complete the work packages and the overarching project as you
are with big muscle movements and milestones being
accomplished on time and budget. Additionally, as a project
manager you have a vast amount of breadth, but typically very
little depth in the various specialties that are required to
accomplish the project. Therefore, it is not feasible nor
necessary for a project plan to identify every single task that
will be accomplished. The project manager should allow is
section managers/leads run their part of the project the way they
see fit because they have a better handle on their resources and
what needs to be accomplished. I would suggest that project
managers focus on the big moving parts and go to the individual
section leads to determine the time, budget, resources, and
project flow and use that large scale information as the skeleton
for their project plan. Also, when you plan out every single
task, if something were to go wrong or a better way of
accomplishing the task were to be found you could jeopardize
the project and contract. Another thing that having too much
granularity to a project does is stifle empowerment. If the
worker on the operations floor knows a more effective or
efficient way of accomplishing a task, but is restricted to what
the project plan says even though the end-state is the same you
run the risk of not being as efficient, effective or creating an
environment with so much micromanaging that it reduces
individual buy-in, which is key to success. I say identify the
necessary information and allow your individual personal the
latitude to innovate within the project time line and budget.
Let me know your thought because my experiential knowledge
is very different from individuals in industry.

The project manager must not reduce the project buffer in an
attempt to accelerate the CCPM schedule. This should not even
be a consideration as it will not accelerate the project. Instead,
it will only increase the likelihood that you will not meet the
deadline and it will increase buffer triggers. According to Leach
(2014), "Two primary options are to get additional resources
where resolving overloads causes the lead time to be increased
and to look inside the tasks for batching opportunities" (p.
191).
Both of these are possible without a negative cost or throughput
impact if managed correctly. You must make sure that you do
not increase the task work when adding an additional resource
as this will have an impact on cost. Batching will require
breaking up the task into smaller pieces. If managed correctly,
both options will accelerate the schedule.

5. Hi,
I need a research paper about one issue facing EMS emergency
medical services
its about 4 pages
i have attached my outline and the format that you need to
follow
the first one is the format of the paper
the second one the my research outlines and references
I need it on Monday April 24th
Make sur that you follow the format attached in the second
word doc
major issue facing EMS emergency medical services
Outline:
Body: one issue
five major issues facing the Emergency Medical Services EMS:
Body: we have discussed Five major issues with Dr. Miller but I
will talk about
Lack of funding/reimbursement issues for EMS services.
Here my outlines:
· What we mean by Lack of funding/reimbursement issues for
EMS services. ?
· Cost of transporting.
· Problem of reimbursing for non-insured patients, moreover
EMTALA Law Emergency Medical Treatment & Labor Act
· How Medicare and Medicaid patients pay for EMS Ambulance
services
· Recommendation

7. Your Name

Title of Paper
CREIGHTON UNIVERSITY
HAP 200 --- INTRODUCTION TO HEALTH CARE
ADMINISTRATION
Put the title of your paper here
Put your name here
Executive Summary: This is a one paragraph summary of your
paper. Write it when the paper is complete.
With the exception of the cover page, Use an 11-point font and
1-inch margins. Also, double space throughout the entire paper
Introduction: This is a one or two paragraph description of the
person you interviewed and his or her organization.
Issue: This is a one or two paragraph description of the issue
you are analyzing, including some discussion of the impact that
the issue has on the organization you visited.
Research: This is a 2 page description of the research you did
on your issue.
This section should not be a discussion of what you think. It
should contain pertinent commentary on the issue by experts
and should be of two types:
· A description of the impact of your issue on health care
· A description of what other health care providers are doing to
deal with the issue or recommendations about the issue made by
experts. To the extent you can, try to identify “best practices”
among health care providers dealing with your issue – ie, find
out what seems to be working.

8. Make sure to note your sources of information, even if you
paraphrase rather than directly quote. For example:
As Jones said, “Blah, blah, blah”.4 However, Smith’s point of
view is that a health care provider should blah, blah, blah.2
Tie the reference notations to your Bibliography. You will have
to Superscript them yourselves, as we are not using the standard
footing format in Word.
Research: This is page two of your research section.
Recommendations: Now it’s your turn. This is a one page
description of what you think should be done. Your
recommendations should be based on your research findings,
mixed with your personal views on the matter.
Bibliography
Put your references here. List them in alphabetical order by last
name of the author. Use standard reference formatting.
You should have at least 5 references, and I strongly
recommend going to the Health Sciences library rather than
relying solely on the internet.
