Unified Communication Platforms

Unified Communication Platforms
Based on your Week Two Learning Team Collaborative discussion, submit, individually, a 2 page APA formatted paper with a comparison of the different kinds of unified communication platforms, such as VoIP and PBX, their features and functionality, with example applications such as Skype or others similar, based on the five criteria.

a.Per the textbook, in order to understand the causal relationship in business process, manager often asks
whys to drill down the root cause of failures. Select one (1) project from your working or educational
environment and propose at least three (3) why questions that you would ask in order to identify root cause
of problem. Justify your responses.
b.The data in the table below is from a study conducted by an insurance company to determine the effect
of changing the process by which insurance claims are approved. The goal was to improve policyholder
satisfaction by speeding up the process and eliminating some non-value-added approval steps in the
process. The response measured was the average time required to approve and mail all claims initiated in
a week. The new procedure was tested for 12 weeks, and the results were compared to the process
performance for the 12 weeks prior to instituting the change.
Table: Insurance Claim Approval Times (days)
Old Process New Process
Week Elapsed Time Week Elapsed Time
1 31.7 13 24
2 27 14 25.8
3 33.8 15 31
4 30 16 23.5
5 32.5 17 28.5
6 33.5 18 25.6
7 38.2 19 28.7
8 37.5 20 27.4
9 29 21 28.5
10 31.3 22 25.2
11 38.6 23 24.5
12 39.3 24 23.5
Use the date in table above and answer the following questions in the space provided below:
1.What was the average effect of the process change? Did the process average increase or decrease and
by how much?
2.Analyze the data using the regression modely=b0 +b1x, wherey= time to approve and mail a claim
(weekly average),x= 0 for the old process, andx= 1 for the new process.
3.How does this model measure the effect of the process change?
4.How much did the process performance change on the average? (Hint: Compare the values ofb1 and the
average of new process performance minus the average of the performance of the old process.)
