正确答案：
(b) In many ways Six Sigma started out as a quality control methodology. It focused on measurement and the minimisation of
faults through pursuing Six Sigma as a statistical measure of some aspects of organisational performance. However, Six Sigma
has developed into something much more than a process control technique. It includes a problem-solving process called
DMAIC and a comprehensive toolkit ranging from brainstorming to balanced scorecards and process dashboards. It also has
defined team roles for managers and employees, often with martial arts names such as Black Belt, Green Belt and Master
Black Belt.
Six Sigma was first used in organisations in the early 1990s. However, it was its adoption and promotion by Jack Welch, the
CEO of GE that brought Six Sigma wider publicity. He announced that ‘Six Sigma is the most important initiative GE has ever
undertaken’. As Paul Harmon comments, ‘Welch’s popularity with the business press, and his dynamic style, guaranteed that
Six Sigma would become one of the hot management techniques of the late 1990s’.
Six Sigma uses an approach called DMAIC in its problem solving process. This stands for Define, Measure, Analyse, Improve
and Control. Three aspects of this are considered below in the context of how they would address the problems at UPC.
Defining the problem
Part of defining the problem is the identification of the customer. It is important to understand what customers really want
and value and one of the main themes of Six Sigma is its focus on the customer. Six Sigma explicitly recognises the ‘voice of
the customer’ (VOC) in its approach. In the UPC situation quality requirements are currently defined by the physical condition
of the goods and by the alignment of the image. However, this may be a limiting view of quality because there is no evidence

of any systematic investigation of the requirements of the customer. Solving these problems may not lead to any significant
long-term gain; they may be quickly replaced by other ‘quality issues’. Furthermore, the customer is also perceived in a limited
way. These quality requirements are in the eye of the gift shop owner who is interested in saleable products. The end customer
– the consumer – who buys and uses the product may have other requirements which can also be addressed at this time.
By considering the VOC the problem and scope of the project becomes re-defined and the solution of the problems potentially
more valuable.
Measurement
Measurement is fundamental to Six Sigma. This includes the gathering of data to validate and quantify the problem. The
creation of the inspection team was based on initial evidence about an increase in breakages. This needs to be quantified.
The inaccurate printing of the image had been quantified as 500 units per month, out of the 250,000 shipped out of the
company. This equates to a failure rate of 0·2%, so that 99·8% of items are shipped with a correctly aligned image. This
sounds quite reasonable but it still raises issues and complaints that have to be dealt with, as well as creating wastage costs
of $10,000 per month. The problem is that even a relatively low percentage of defects can lead to a lot of unhappy customers.
Aiming for Six Sigma would reduce defects down to about one faulty item per month, reducing the wastage cost to $20.
Analysis
Analysis is concerned with understanding the process to find the root cause. Six Sigma focuses on processes and their
analysis. Analysis concerns methods, machines, materials, measures, Mother Nature and people. The alignment problem
needs investigation to find out what causes the imaging machine to irregularly produce misaligned images. Management
currently appear to blame the machine but it may be due to the way that certain people load the machine. The analysis of
the breakages is particularly important. It is unclear at present where these breakages occur (for example, are some of the
items broken before they leave UPC’s despatch facility) or are they all broken in transit? Neither is it understood why the
breakages occur. Management appear to blame the packers for packing incorrectly and not following the correct method.
However, it may be that the material is just not strong enough to withstand heavy handling by couriers who are outside the
control of UPC. Additionally, the breakages may be due to some manufacturing problem or raw material imperfection in the
items that break. Six Sigma stresses understanding the problem before solving it.
Although DMAIC has been selected as the framework for the sample answer, focusing on other aspects of Six Sigma would
be acceptable – as long as they are presented in the context of the UPC scenario.

正确答案：
(b) Sergio’s investments
Sergio aims to leave a substantial asset to his family on his death. Accordingly, in view of his age, he is right to be considering
investing in an asset whose value is unlikely to fall suddenly, such as a domestic rental property. However, it must be
recognised that although the value of land and buildings can usually be relied on to increase over a long period of time, its
value may fall over a shorter period. The only investments that cannot fall in value are cash deposits, although they do, of
course, fall in real terms due to the effects of inflation.
Sergio should consider whether or not he wishes to increase his annual income. The return on capital invested in a domestic
rental property is unlikely to be very high due to the recent increases in property values in the UK. Also, there are likely to be
periods when the house is unoccupied during which no income will be generated. If it is important to Sergio to generate
additional income he should consider other low-risk investments with a more reliable and higher rate of return, for example,
gilt edged stocks, unit trusts and cash deposits.
Sergio must also decide whether it is important to him to be able to access capital quickly, as it is usually not possible to
realise the capital invested in land and buildings at short notice. If this is important, Sergio should consider holding some of
his capital in cash deposits or other liquid investments, eg unit trusts.
Sergio could invest up to ￡7,000 each year in an individual savings account (ISA). A maximum of ￡3,000 can be held as a
cash deposit with the balance invested in quoted shares. The income and gains arising on the funds invested would be
exempt from both income tax and capital gains tax. This would be a relatively low-risk investment and would also be
accessible quickly if required.
