1. Process Flow Diagram The Process Flow Diagram, or PFD, of Manzanas Fruitvale branch is shown in figure
1. Some important features of the PFD are as follow:
The coloured arrow is used in order to differentiate the origin of insurance
request. As shown in the diagram, the RUN, RAIN and RAP are originated
from the customer. On the other hand, the RERUN is originated from the
branch record.
The black arrow explains the path that each policy undergoes before being
delivered to branch record, customer and agent.
Automatic Renewal System represents the current computerised system to
produce RERUN request.
The Branch Record is assumed to store both hard copy and soft copy of the
policy, and the data is used as the input for Automatic Renewal System.
The elements involved in the PFD are used base on the general convention of process
flow diagram, which is discussed by Foster, 2013.

2. Performance of Manzanas Fruitvale Branch The assessment of the branch performance is conduced based on two key measures.
These two key measures are financial and operational performance.
2.1. Financial Performance The data used in analysing the financial performance is taken from the Financial
Summary, Fruitvale Branch in Exhibit 5 of the case study. The key concept in
analysing this performance is based on the ability of the branch to achieve satisfactory
results or positive trend on some important economic data. The failure of meeting
these criteria indicates the existence of problems, or issues, that can be verified based
on the operational performance.
2.1.1. Branch Profit
The profit is an accounting measure, and the value is obtained by subtracting revenue
with expenses (Sullivan, 2012). In general, the revenue of a healthy company is more
than the expenses, and therefore profit is generated, otherwise there will be financial
losses. = [1]
The profit of the branch is shown in the following figure.

Some key points based on figure 2 are as follow.
The trend of the profit is assumed to follow linear regression.
The reliability of the trend line is assessed based on the R-Squared value. A
reliable trendline commonly has R-Squared value of 1 or near 1 (Microsoft,
2013). The R-Squared value of the profit trendline is 0.94586, thus the
trendline is reliable.
The slope of the trendline is -244.21, thus the profit has a negative trend.
There are two significant financial losses in the last two quarters.
The negative trend and losses are mainly due to the gradual drop of revenue and not
because of increase in operating expenses. The operating expenses increased by
approximately 16.31% from the first quarter of 1989 to the first quarter of 1991,
mainly due to Finance Charge and introduction Salary/Plus program. This increase is
less significant in compare to the significant drop of gross underwriting result of
approximately 56%. The computation is summarised in the following table.

Furthermore, the significant elements that construct the gross underwriting result are
the net underwriting revenue and the ordinary losses. As can be seen in figure 3
below, there is minimum variation of net underwriting revenue throughout the period,
while the ordinary insured losses has been drastically grown over the period.

Figure 3 Gross underwriting results analysis
2.1.2. Market Share
The drastic growth of ordinary insured loss shows contradiction between market share
and amount paid to the customer in term of ordinary insured loss. The amount of
ordinary insured loss is commonly increased if the market share is increased as well,
or there is a positive correlation. In the case of Fruitvale branch, the ordinary
insurance loss increased, but the market share decreased due to high renewal loss.
This issue can be addressed by analysing the ratio between ordinary insured loss and
the total policy. The analysis is summarised in the following figure.

The increasing ratio in figure 4 indicates the existence of problem in regard to the
quality of the customer, performance of the agent and the companys underwriting
standard. These issues will be addressed in the later section of this assignment.
2.1.2. Renewal Loss
The lack of ability of the company to maintain their existing customer is represented by the
high renewal loss. The renewal loss has a significant impact toward the profitability of the
branch. The revenue generated by the renewals is shown in the figure 5 below. The revenue
generated by the renewal starts to decrease from the first quarter 1990, and it cancels out the
revenue generated by the new policies. Thus, it has a direct effect toward the profitability of
the branch.
Figure 5 Renewal (Dollar Value)
2.2. Operational Performance The operational performance of the branch is assessed based on three main measures.
These measures include customer satisfaction level, employee attitudes toward
companys strategy and day-to-day operation performance.
2.2.1. Customer Satisfaction
The performance measures in regard to customer satisfaction in this case study are the
turnaround time, late number and renewal loss rate.

Turnaround Time (TAT)
As indicated in the case study, the TAT has increased from three days to more than
five days. This is a significant competitive disadvantage for Fruitvale branch knowing
that agents typically send their clients to the company with the shortest TAT, mainly
due to the opportunity for obtaining commission earlier or selling more policies. It is
clear that in the insurance industry the TAT is a key item. The situation is worsens
due to the fact that Golden Gate, Manzanas main competitors, has decided to
implement a guaranteed TAT of one day. Thus, a significant change toward
improvement of TAT is necessary if Manzana want to stay competitive in the
business.
Late Number
Pareto Analysis is conducted in order to justify that the RERUN has the most
significant affect toward the total late figure. The data for the analysis is taken from
Exhibit 6, and the result is shown in the figure 6 below. The result shows that RERUN
contributes to more than 80% of the total late figure. The high late figure on the
RERUN indicates poor service toward the current customer, and thus it lead to poor
customer satisfaction level.
Figure 6 Pareto analysis in late policy
Furthermore, the reason behind the high renewal late is due to the priority that is
given to new policy. The summary in Exhibit 6 shows that the late figure of RUN and
RAP is zero, while RAIN and RERUN increase throughout the year. This issue is
strongly related to the profit generated by new policy and the employee attitude

toward the implementation of Salary/Plus system, which will be discussed in detail in
the later section of this assignment.
Renewal Loss Rate
The high number of renewal late leads to high renewal loss rate. As shown in the case
study, the renewal loss rate increased from 33% in the second quarter of 1990 to 47%
in the second quarter of 1991. On the other hand, the renewal loss rate of Golden
Gate, Manzanas main competitor, is 15%. Although renewals do not generate high
profit for the company, losing some market share each year is a major problem.
The lost of market share can be measured quantitatively by analysing the renewal rate
figure, which is derived from the data given in Exhibit 7. In 1989, renewal rate was
85.9% and it decreases to 69.2% in 1991. The computation is summarised in the
following table.

Renewal Lost 849 1717 926
Total 6015 6704 3007
Renewal Rate (%) 85.89% 74.39% 69.21%
Table 2 Summary of renewal rate
2.2.2. Inconsistency in Following Company Policy
The company has used first-in-first-out (FIFO) system as a policy for considering
requests. However, this policy is not support by employees. As mentioned before, the
employees tend to give priority to new policy. The discussion of the violation of
company policy, which includes the cause and the affect, will be included in the next
section of this assignment.
2.2.3. Uncontrolled Day-to-Day Operation
The data on policy processing time in Exhibit 4 shows that there is a lack of
standardisation in performing a task. This issue is justified based on the high number
of standard deviation, which mean there is a significant variation in performing a task.
The worse case scenario is taken from the processing of RERUN in the underwriting
department. The mean in performing the tasks is 18.7, while the standard deviation is
-

19.8. This issue will be further analysed in detail in the next section by using the
statistical concepts known as coefficient of variation.
2.3. Outcome The outcome of this analysis is that the branch performance is poor in term of both
financial and operational. In term of financial performance, the branch profit has a
negative trend and there is a significant loss in the last two quarters. Next in term of
operational performance, the ineffective day-to-day operation and poor attitude of
employee toward company policy adversely affects the customer satisfaction level.
The TAT has increased recently, and the renewal late and loss rate also increase
recently which indicates poor customer satisfaction and lost of market share.

3. Issue Analysis This section focuses on the issues that have been addressed in the previous section as
well as the causes of these issues. The following figure summarised the issue analysis
of the Fruitvale branch.
Figure 7 Issue tree

3.1. Relationship Among Problems
3.1.1. TAT and Renewals
The main relation of TAT toward renewal late and loss are mainly the use of TAT to
set the due date of new policy. The new policy is currently prioritised in different
department, thus the renewal process will be further delayed. This delay will increase
the renewal late, in which turns out to be renewal loss.
3.1.2. TAT and Profit
The main relation of TAT and profit is that the agents use TAT as the main criteria to
measure the branchs capability. The high TAT leads to competitive disadvantages,
thus it will be less attractive to the agents. Furthermore, it will lead to lower incoming
customer, thus lowering the profitability of the company.
3.2. The Causes of High TAT
3.2.1. Inconsistent Implementation of Operational Strategy
The original operational policy in each stage of the underwriting process is First-In-
First-Out (FIFO) system in which orders are processed in the same order in which
they arrive (Mieghem, 2005) . The FIFO system in Manzanas operational context can
be defined as the documents, or requests, are processed in order of their arrival,
regardless of the importance and the complexity of the requests. However, the
implementation of this policy is considered to be ineffective. The ineffective
implementation of FIFO system is caused by the lack of supervision, the shortage of
leadership and authority as well as the implementation of Salary/Plus system.
The manger of each department shows a negative attitude toward correct
implementation of FIFO policy. The manager in the underwriting department prefers
to prioritise RUN and RAP due to its profitability, while the manager of the policy
writing prefers to priorities simple task for the purpose of reducing the backlog.
Furthermore, the lack of authority and leadership is shown in the attitude of manager
of rating department. The manager recognise the issue and the affect of violating the
FIFO policy, but the manager could not fix the problem due to the order given by the
higher management.
-
13
The second cause of violation of FIFO policy is the company's strategy of giving
incentive for each new policy completed and such incentive was not applied for the
renewals. This quantitative performance measure leads to prioritisation of request,
thus the FIFO policy is violated. Furthermore, the main outcome of this issue is the
non-value added activity, which is sorting the document by priority. This activity
leads to high backlog number, which adversely affect the computation of TAT.
3.2.2. Poor Resource Scheduling and Allocation
The poor resource scheduling is justified based on the unbalance workload throughout
the period, and it results in either overtime or idle period. Next, the poor resource
allocation can be analysed based on the utilisation rate in each department. The
computation summary of the utilisation rate is shown in the following table. The
utilisation rate shows that the rating and policy-writing department are overstaffed,
which result in low utilisation rate.
Table 3 Utilisation rate
The significant cause of this problem is the outdated data of processing time required.
The inaccurate data leads inaccurate estimation of the resource and time required to
complete the job. Further, the affect of poor resource allocation and scheduling is
mainly due to the backlog that it creates. The large number of backlog affects the
computation of TAT.
3.2.3. Unstandardized Working Procedure
The data provided in Exhibit 4 shows that the 95% SCTs are derived based on the
policy processing time, and inconsistent processing time will lead to inaccurate SCTs.

The inconsistent processing time is justified based on the high standard deviation
values in some of the process stages. The selected quantitative analysis in order to
provide an objective measure of the inconsistency is coefficient of variation.
The coefficient of variation, or CV, is the relative dispersion, and it is computed as
the percentage ratio of the standard deviation to the mean. The general interpretation
of CV is that data with CV of 30% or more indicates lack of process control (Brown,
1998). The mathematical equation for CV is as below. Next, the CV for policy
processing time in each stage is calculated using the CV equation, and the result is
summarised in table 4 below.
% = 100%
Coefficient of
Variation
Type of Policy
RUNs RAPs RAINs RERUNs
Distribution 44.8% 49.8% 21.1% 22.1%
Underwriting 73.4% 64.5% 51.8% 105.9%
Rating 27.2% 21.0% 24.3% 12.8%
Policy Writing 14.5% - 15.9% 19.0%
Table 4 Coefficient of Variation Result
The computation shows that the process variation in Distribution and Underwriting
department is mostly out of control with respect of 30% limit as specified by Brown,
1998. The variation of rating department is relatively high, while the processing time
in Policy Writing department is relatively in control.
Furthermore, in relation to the computation of TAT, the uncontrolled process leads to
high variation and SCT, and therefore the TAT will be overestimated. The
introduction of standardised procedure may be able to provide better process control,
and therefore the TAT will be more accurate. The relation is shown in Figure 1 below.
-

Figure 8 Relation between process control and TAT
3.3. The Causes of High Renewal Late and Losses
3.3.1. Unreasonable RERUN Processing and Due Date
The renewal losses and late rate are related to unreasonable RERUNS processing and
due date. A computer automatically generated a RERUN 30 days before the
anniversary of the policy and the anniversary became the due date. However, the
RERUNS will be released at the last day before the due date which leads to the
congestion of RERUNS and less flexibility of process, and this will ultimately cause
the high rate of renewal late and losses and long time TAT.
3.4. The Causes of Negative Profit
3.4.1. Poor Originating Agent Performance
The number of new policy written and the ordinary insured losses are the two main
parameters that can be used to measure the performance of originating agent. Based
on the financial summary in Exhibit 5, the net underwriting revenue is relatively
stable while the number of ordinary insured losses increases rapidly from $4,176,000
in the first quarter of 1989 to $6,453,000 in the second quarter of 1991. The total
number of policies is decreasing in this period so the rise of the ordinary insured
losses can be explain with the selection of bad customers by the agent. In addition, the
poor relationship and lack of communication between the branch and agents is one of
the contributing factors of this issue. Thus, the agents might prefer other property-
insured company due to lower TAT and result in a rapid increase of ordinary insured
losses.
3.4.2. Implementation of Incorrect Strategy
The new management implement a new strategy in which the branch was divided into
three territories based on the geographic position. The main purpose of this strategy is
-
16
to improve the responsiveness toward the agent. Nevertheless, from Exhibit 7, it is
clearly shown that from 1989 to 1991, the number of lost renewals increased from
849 to 1852 (two times of 926 in first 6 months in 1991) and the Gross premium was
nearly constant during two years. As a result, it seems that the geographical
restructuring is ineffectiveness and it has a significant impact to the companys
profitability.

4. Problem in Turnaround Time (TAT) Calculation The Turnaround Time, or TAT, is defined as the number of days between the receipt
of a new commercial policy, or RUN, and the issuance of a final policy. The
calculation of TAT by Fruitvale branch is included on Exhibit 3. The context of this
calculation is based on the ending week of September 6, 1991.
There are some problems identified in regard to the current calculation of TAT. The
following are a brief list of the identified problems:
1. Obsolete input data from Exhibit 4
2. Incorrect assumption of process start-up
3. Incorrect assumption of requests transfer procedure
4.1. Obsolete Data The TAT calculation in Exhibit 3 is taken from 1991 context, and it utilised the
Standard Completion Time, or SCT that is constructed based on the policy processing
time in 1986. These SCTs are considered to be obsolete due to the installation of
computer system in Rating and Policy Writing Department during late 1980s and
early 1990s. The installation of computer system has significantly reduced the
processing time required to complete activities in these two departments. Therefore,
the utilisation of the 95% SCTs of Rating and Policy Writing Department is not valid,
and it leads to overestimation of TAT. Furthermore, the utilisation of the old data in
the TAT calculation shows that the company does not have a clear strategy in
managing their data.
4.2. Inaccurate Assumption of Process Start-up The computation of TAT in Exhibit 3 is conducted based on the assumption that, the
process in the next department can only start once the process in the previous
department has been completed, regardless of the requests that are currently in the
queue. For example, the requests in the Underwriting Departments (3 RUNs, 7 RAPs,
6 RAINs and 36 RERUNs) cannot be processed until the requests in Distribution
Department have been completed, or in other word the Underwriting Department
needs to wait for approximately 0.6 days before they can start the process. The
graphical representation of this issue is shown in figure 9 below.
-
18
Figure 9 Sequential process start-up assumption
The assumption of the sequential process start-up leads to overestimation of TAT.
The alternative assumption that can be used to estimate TAT is by assuming processes
in a different department start in a parallel manner. It means that each department will
immediately process requests that are currently in the queue and does not wait for the
previous department to complete their tasks. This assumption will reduce the
estimation of TAT as well as improving its accuracy. The graphical representation of
this assumption is shown in the following figure.
Figure 10 Parallel process start-up assumption
-
19
4.3. Incorrect Assumption on Requests Transfer Procedure The current computation of TAT assumes that the requests are transferred in batch.
This assumption is incorrect since the company does not implement a batch transfer
policy, and it also results in overestimation of TAT. Thus, the individual transfer is
preferable and the use of this assumption may improve the reliability of TAT.
Furthermore, the utilisation of individual transfer required addition delay period to
prevent underestimation of TAT.

5. Recommendation to Fruitvale The availability of information ranging from the companys background,
organizational structure, operating procedures and the companys performance is
utilised for revising and modifying the company strategy and policy. This information
serves as roadmap for the recommendation for further improvement.
The proposed recommendations for solving the identified issues are discussed in
detail in this section. The discussions for each recommendation include the related
issue, the recommendation proposal and its effect toward further improvement.
Lastly, a matrix diagram is included as the basic guideline on the significance of
recommendation toward further improvement.
5.1. FIFO System and Penalty Related issue:
The teams in different department are currently prioritising the incoming
request, thus the policy is violated.
Recommendations toward the issue:
Emphasise the criticality of FIFO policy
Emphasise the importance of customer satisfaction, not the premium
generated by the policy
Introduce supervision system to ensure the policy is followed, and allocate
penalty
Effects toward improvement:
Reduces the non-value added activities, such as sorting
Reduces the renewal late and lost due to the elimination of prioritisation.
Reduces TAT
Improve the net income
-
21
5.2. Revaluate Turnaround Time Computation Related issue:
The high turnaround time is a main competitive disadvantage for the branch.
Recommendations toward the issue:
Revaluate the method in estimating TAT due to some issues in the
computation that have been addressed previously. The additional information
for correct TAT computation can be obtained by benchmarking the
computation.
Revaluate the input data for estimating TAT.
The effect toward improvement:
Improvement of TAT in term of low TAT and its accuracy
5.3. Revaluate Salary/Plus System Related issue:
The introduction of Salary Plus system leads prioritisation of new policy since
the incentive will be paid only for each new policy written about quota.
Recommendation toward the issue:
The incentive will be paid for all policy written above quota. This action will
increase the operating expenses, but the benefits, in term of improvement in
revenue, will overcome the increase in expenses.
Effects toward improvement:
Enhancing the FIFO policy
Reduces the renewal late rate
5.4. Revise the Agents Commission Related issue:
The significant gap of renewal commission (7%) and new policy (25%)
motivates the agent to focus on getting a new customer despite of the quality
of the client.
Recommendation toward the issue:
Decrease the gap between the commissions by increasing the commission of
renewal policy.
-
22
Effect toward improvement:
The good quality customer will reduce ordinary insured losses, thus improving
the branchs profitability.
5.5. Revise the Terrorise Strategy Related issue:
The division of territory strategy is introduced to improve the responsiveness,
but this strategy in fact increases the renewal lost, thus it is ineffective.
Recommendation toward the issue:
Bringing the underwriting teams together in order to centralised the policy
processing.
Effect toward improvement:
Even and balance workload for employee
Reduce the TAT due to better resource utilisation
5.6. Guideline for Computerised System Related issue:
The implementation of computerised system to ensure on time RERUN
processing is not effective due to lack of guideline.
Recommendation toward the issue:
Establish the clear guideline in regard to receiving and processing RERUNs
that are generated by the computerised system
Effect toward improvement:
Prevent unnecessary delay of RERUN process, thus reducing the renewal late.
5.7. Data Management System Related issue:
The out-dated data used in the TAT calculation leads to inaccurate estimation,
thus a proper data management system needs to be implemented for the
purpose of regular data update.
Recommendation toward the issue:
Implementation of data management system such that regular update from the
main company can be obtained in a real time manner.
-
23
Effect toward improvement:
Improve the accuracy and reliability of TAT calculation and other related
computation.
5.8. Standardise Working Procedure Related Issue:
The large variation of the process in each department leads to high TAT
computation.
Recommendation toward the issue:
Establishing a standard working procedure that provides clear guideline of the
step-by-step procedures that need to be done for different policies in different
department. The use of graphical representation, such as flowchart, can be
implemented to improve the effectiveness.
Effect toward improvement:
The low variation of process leads to lower Standard Completion Time (SCT),
thus it reduces the overall TAT estimation.
5.9. Outcome The matrix diagram is constructed in order to show the priority of the
recommendation and inform the management regarding the significance of each
recommendation. The matrix diagram is shown in the following figure.
