Current Events Crisis Analysis Essay
This paper should be written in an APA-Style format.
Your paper will be evaluated on the following:
· Content
· Grammar
· Structure and mechanics
· Relevance to the topic(s)
Note: Each essay will be submitted through Canvas
Current Events Crisis Analysis:
This assignment requires students to identify and examine a
current example of a crisis taken from the news. Students will
analyze various elements for consideration and apply course
concepts. Students will critique the company/individual in terms
of what was done well and what perhaps could have been
orchestrated better and why.
Instructions:

14. Write about a company or industry that has faced or currently
faces a crisis (or that is grappling with an issue which threatens
to become a crisis.)
Include the following components: 1) analyze the underlying
causation); 2) a stakeholder analysis; 3) review what the
organization did in response, and 4) evaluate its effectiveness
and determine whether other approaches might have been taken.
You should do an analysis rather than a description. In addition,
you should include documentation of source material. Finally,
whichever sort of topic you choose should be of real interest to
you.
Length:
3-5 pages (it’s expected that you employ sources, attributions
and bibliography.)
Be sure to provide informed and thoughtful answers to all of the
guideline suggestions/questions.
Style:
APA Format
Visit the Purdue Online Writing Lab for more help with APA
formatting.
Guidelines:
I. Define the organization and its crisis / potential crisis.
II. Crises develop in four stages: Warning (detection,
prevention, preparation), Point-of- no-return (containment),
Cleanup (recovery), and Back-to-normal (learning). What
stage(s) apply to this crisis?
III. Who do you think is in charge of managing the crisis?
a. What are their highest priorities?
b. What are their motives behind their decisions?
IV. Attempt to define the stakeholders and their concerns.
a. What are the communication strategies?
b. What are the messages?
c. Are there any inconsistencies between early response and
later response?

15. d. Did the organization utilize any intermediaries to help
manage its relationships with stakeholders?
V. Evaluate the organization’s responses.
a. Restores trust? Damaging? Honest? Explanatory? Plain
speech vs. technical speech? Deflects or invites participation of
those affected to seek solutions? Ignores, meets or exceeds
stakeholder expectations?
b. Were concerns dismissed? Was blame cast elsewhere? Were
mistakes acknowledged? Sympathetic? Were public apologies
made?
VI. In your opinion, how well was the organization prepared for
this crisis? Explain.
VII. If an organization’s reputation has been damaged, how
might it be restored?
VIII. Can you detect or predict any potential benefits from this
crisis?

you will receive written feedback on your assignment.
5. Late submissions will only be accepted for a maximum of 7
days past the due date. For every day an assignment is late, 10%
