Analysis of a Virtual Sales System with Call Centers in Two Separate Locations
After taking into consideration the system change in late February, and withholding January and
February numbers from the control chart, one can conclude that SAB Conversion is in statistical
control for the complete system. The system averages 55% and can range from 34% to 75% in any
given month.
16
Final analysis looking at both locations as the complete system
Based on the above data and analysis, and after adjusting for changes in the system, one can conclude that for all performance measurement metrics, the system as a whole is in statistical control.
Looking at each location as its own system
As mentioned earlier, although the sales operations of this division are considered virtual, there are
regional, leadership, communication and personnel differences that can impact overall performance of
a location. Because of this, it is logical to look at each location as if it were its own system.
For the below analysis, the performance numbers for each location were separated and placed into
separate control chart. From there, a side by side analysis was completed comparing each location’s
performance in the chosen metrics.
Please reference 3.1.1 and 3.1.2 for the issue rate side by side analysis in each location:
17
Analysis of 3.1.1 and 3.1.2:
Based on the above graph, both locations are in statistical control for the issue rate. The North
location is averaging 44% and can range from 37% to 52% in any given month. The South location
also averages at 44% but ranges from 48% to 40% in any given month. One point of interest is the
South location has a lower standard deviation of only 29% compared to the North’s standard deviation
of 47%. The lower standard deviation may mean the South is more consistent in their conversion rate
and the North has higher peaks and valleys. Regardless, the side by side comparison of issue rate does
not indicate any major concerns.
Please reference 3.2.1 and 3.2.2 for health conversion rate side by side analysis for each location:
Analysis of 3.2.1 and 3.2.2:
In regards to health conversion rate, both locations are in statistical control. The North location
averages a 13% health conversion rate ranging from 11% to 14% in any given month. The South
location averages 12% and can range from 10% to 14% on any given month. When comparing the
averages from each location, the difference is only one percent. One percent is not significant enough
to take action.

Please reference 3.3.1 and 3.3.2 for dental conversion rate side by side comparison each location:
Analysis of 3.3.1 and 3.3.2:
For Dental conversion, both locations are in statistical control. However, for Dental conversion the
North location averages 7% higher than the South location. The North is averaging a 54% Dental
conversion verses South’s 47%. The 7% difference may be significant. More analysis will follow.
19
Please reference 3.4.1 and 3.4.2 for life conversion rate side by side analysis for each location:
Analysis of 3.4.1 and 3.4.2:
With regards to Life conversion, both locations are each in statistical control. However, like Dental
conversion, the South location is averaging lower. For Life conversion, the North is averaging 26%
and the South is 17% producing a 9% difference.
Please reference 3.6.1 and 3.6.2 for SAB conversion rate Side by Side analysis for each location:
20
Analysis of 3.6.1 and 3.6.2
Note: In the analysis of SAB conversion that included both locations as one system, the final analysis
looked at metrics from March through September. It was determined that in February, the system was
changed which improved the system starting in March.
When analyzing SAB conversion for each location, one can see the North’s SAB conversion is in
statistical control and South is not. Further analysis to determine why the South location was out of
statistical control in March revealed the awareness and training campaign did not happen until March.
As a result, the sales representatives did not have the knowledge and tools they needed to improve.
When comparing averages the North is converting SAB at 70% compared to South’s 48%, a 22%
difference.
Summary of between group variation analysis of performance metrics
Based on between group variation analysis, the differences between locations for health conversion
and issue rates are negligible. When analyzing the sales performance of the ancillary products, a
significant profit center for the division, the performance in the South location has lower average
performance than the North location.
For further analysis, within group variation (Supervisor to Supervisor) was needed.
Within subgroup variation analysis of performance metrics (Supervisor to Supervisor)
As indicated in the between group variation analysis, the conversion rates for the ancillary products,
Dental, Life and SAB, indicated an opportunity for further analysis. To do further analysis, the data
was restacked so each supervisor’s team performance was analyzed compared to the other supervisors.
In the analysis, N1 through N4, in the data set, and points one through four in the control charts,
21
represent the North supervisors. S5 through S9 in the dataset and points five through nine in the
control charts, represent the South supervisors. See results below:
Please reference 4.1 for dental conversion rate analysis by supervisor:
Based on control chart 4.3, supervisor team N1, N3 and N4 are out of statistical control on the high
side and teams S6, S7, S8 and S9 are out of statistical control on the low side. In summary, three out
of four North supervisor teams are exceeding the limitations of the process in regards to SAB
conversion. In comparison, three out of five South supervisor teams are below the system limitations
in regards to SAB conversions.
Summary of all Control Chart Analysis
In summary, based on analysis of all sales performance analysis metrics, one can conclude the South
location is lacking in their ability to sell the three ancillary products of Dental and Life Insurance and
the Supplemental Accidental Benefit Rider. Considering the ancillary products are a profit center for
this division, determining the reason for the discrepancy, and finding ways to improve the
performance of the South location will increase overall profit.
25
Why is the South location not selling ancillary products as well as the North?
To help diagnose why the South location is not selling ancillary products as well as the North the
following cause and effect diagram was constructed.
Please reference cause and effect diagram 5.1:
Analysis and discussion of figure 5.1
Based on the analysis of figure 5.1 three areas were identified that interrelate which may be a cause for
the deficiency in ancillary sales production. Please reference the areas highlighted in yellow in figure
5.1.
Starting with the environment, the South job market is extremely competitive in regards to call center
jobs. As a result, in the 2008 calendar year the South office hired only 16 new sales representatives.
26
Conversely, the North location’s geographic area was able to recruit more effectively and hired 29
new sales associates. Basically, 65% of the North location’s sale representatives have been hired in
the last 12 months compared to 26% in the South location.
After reviewing training documentation and records, it was found that early in 2008 new hire training
was drastically modified, in an effort to make new hires more productive post training. Part of this
modification included a new strategy, expectation, and emphasis on how ancillary products were
offered and sold. In the training, new hires were given ample opportunity to practice and apply the
concepts. As a result of the improved training, the new hires were able to effectively cross offer and
sell our ancillary products immediately.
The new strategy and expectations were provided to veteran reps through self learning materials and
team meeting discussion groups. There was no formal training or change management measurement
implemented to insure that veteran reps would correctly apply the methods and expectations. In
addition, veteran reps did not have ample opportunity to practice using the new strategies.
Again referencing figure 5.1, none of the South or North management team attended the modified
training for ancillary product sales. Although many provided feedback and input into the development
of the materials, none sat through the training. For the North group, leadership not attending the
training may not have as large an impact on ancillary sales conversion, because 65% of their staff
received the modified training. For the South location, supervisors and managers not attending the
training may have had a much larger impact, because 74% of their staff consisted of veteran reps that
had not had the new training. The new concepts were reportedly facilitated, for veteran reps, through
supervisors in team meetings in both locations. Due to the fact the supervisors had not been formally
trained on the new materials, the effectiveness of the facilitation is in question.
27
In summary the cause derived from figure 5.1 was that a major reason why the South location was
lacking in ancillary sales performance was because a large portion of their staff did not have sufficient
training and development.
Short summary of modified training for new hires
The modified ancillary products sales training for new hires consisted of the below basic concepts:
1. Dental Insurance, Life Insurance and Supplemental Accident Benefit (SAB) are offered on
every application, with no exception.
2. The offer should not be in the form of closed ended question.
3. The offer needs to focus on providing detail on the main value and benefits of each product
first and then ask the consumer if they are interested.
There is much discussion and the purpose and reasoning of each concept above; however, it is out of
the scope of this paper.
Final analysis of ancillary product conversion performance
The final analysis of the performance of each location’s ancillary product performance focused on
listening to actual calls. For compliance and auditing purposes, all calls coming in and out of the call
centers are digitally recorded. Utilizing this technology, 100 random calls in each location were
audited. The calls were recorded on a check sheet and then placed into a Pareto diagram. The
following details were audited on each call.
1. Were all three ancillary products offered using modified training techniques
2. Were two of the three ancillary products offered using modified training techniques
28
3. Was one of the three ancillary products offered using modified training techniques
4. Were all three offered not using new techniques
5. Were two of the three offered not using new techniques
6. Was one offered not using new techniques
7. Were none offered
The check sheets offered the following data:

Analysis of Pareto Charts 7.1 and 7.2
30
From charts 7.1 (South Call Analysis) and 7.2 (North Call Analysis), it is evident the new ancillary
product selling techniques are not being utilized in the South location. Per 7.1, in 29% of calls the
ancillary products were not even mentioned. In 69% of the calls either no ancillary products were
offered or if they were offered, the outdated method was used.
Per 7.2, the complete opposite performance was recorded in the North location. In 29% of calls all
three ancillary products were offered using the new technique. In 70% of calls the new strategy was
used for at least one ancillary product sales attempt.
Summary of all analysis
Based on all the analysis, data and quality tools provided, it is evident the south location is lacking in
ancillary sales ability. This responsibility of this deficiency does not rest on the sales associates, their
supervisors or even their management. The successes of the North location in regards to cross
offering ancillary products can not be entirely attributed to the performance of the supervisors or
managers as well.
From looking at each location as a separate system, there is a strong indication the employee recruiting
market may be a factor. The division in performance exists due to the fact the overwhelming majority
of 2008 recruiting and hiring was done in the North location, combined with the enhanced and
modified ancillary sales training, for new hires.

Final Recommendations
In an effort to increase overall profitability, through the sales of Dental and Life Insurance and the
Supplemental Accident Benefit Rider, additional training is recommended:
1. Training calibration needs to be completed between sales trainers in North and South locations
to insure consistency in the content and delivery of ancillary product sales training.
2. Ancillary product sales training workshop for all North location representatives.
3. Ancillary product sales training workshop for all North Supervisors and Managers.
4. Ancillary product sales training workshop for all South locations representatives who have
tenure of greater than 12 months.
5. Ancillary product sales training workshop for all North supervisors and managers.
