CFO FORUM MEETING
MOSSEL BAY
5 & 6 DECEMBER 2011
• What is a standard?
• 1. Put at its simplest, a standard is an
agreed, repeatable way of doing
something.
• 2. It is a published document that contains
a technical specification or other precise
criteria designed to be used consistently
as a rule, guideline, or definition.
• 3. Standards help to make life simpler and
to increase the reliability and the
effectiveness of many goods and services
we use.
• 4. Standards are created by bringing
together the experience and expertise
of all interested parties such as the
producers, sellers, buyers, users and
regulators of a particular material,
product, process or service.
• 5. Standards are designed for
voluntary use and do not impose any
regulations. However, laws and
regulations may refer to certain
standards and make compliance with
them compulsory.
• 6. Any standard is a collective
work. Committees of
manufacturers, users,
research organizations,
government departments and
consumers work together to
draw up standards that evolve
to meet the demands of
society and technology.
7. Something considered by an authority or by
general consent as a basis of comparison; an
approved model.
8. An object that is regarded as the usual or
most common size or form of its kind: We
stock the deluxe models as well as the
standards.
9. A rule or principle that is used as a basis
for judgment:
10. An average or normal requirement, quality,
quantity, level, grade, etc.
Standard Deviation and Variance
Deviation just means how far from the normal Standard Deviation The Standard Deviation is a measure of how spread
out numbers are. Its symbol is σ (the Greek letter sigma) The formula is easy: it is the square root of the
Variance. So now you ask, "What is the Variance?“
The Variance is defined as: The average of the squared differences from the
Mean. To calculate the variance follow these steps:
•Work out the Mean (the simple average of the
numbers) •Then for each number: subtract the Mean and square
the result (the squared difference). •Then work out the average of those squared
differences. (Why Square?)
Mean =
600 + 470 + 170 + 430 + 300 =
1970
= 394
5 5
Example You and your friends have just measured
the heights of your dogs (in millimeters):
The heights (at the shoulders) are: 600mm, 470mm, 170mm,
430mm and 300mm. Find out the Mean, the Variance, and the Standard Deviation. Your first step is to find the Mean: Answer:
So the mean (average) height is 394 mm. Let's plot this on the chart:
To calculate the Variance, take each difference, square it, and
then average the result:
So, the Variance is 21,704. And the Standard Deviation is just the square root of
Variance, so: Standard Deviation: σ = √21,704 = 147.32... = 147 (to
the nearest mm)
And the good thing about the Standard Deviation is
that it is useful. Now we can show which heights are
within one Standard Deviation (147mm) of the Mean:
So, using the Standard Deviation we have a "standard" way of knowing what is normal, and
what is extra large or extra small.
Rottweiler's are tall dogs. And Dachshunds
are a bit short ... but don't tell them!
ARE MUNICIPALITIES LIKE
DACHSHUNDS ???
•ARE WE A BIT SHORT IN CASH ?
•OVER BORROWED ?
•ARE SALARIES TOO HIGH ?
•CANNOT AFFORD TO PAY FOR
BULK SERVICES – WATER AND
ELECTRICITY ?
•LACK OF MAINTAINING
INFRASTRUCTURE ?
•CANNOT AFFORD SERVICE DELIVERY AT
A HIGH OR ACCEPTABLE STANDARD or
NORM ?
CANNOT AFFORD TO PROVIDE IN CASH
FOR THE REPLACEMENT OF
INFRASTRUCTURE OF THE PAST AND
PROVIDE FOR THE FURTURE
(DEPRECIATION)
•WE KNOW WE ARE IN SOME SORT OF
TROUBLE, BUT PLEASE DON’T TELL US

THE WAY FORWARD
• Swartland Municipality will get information on the
said excell format from the various 5 B municipalities
in the West Coast via the West Coast District
Municipality. WCDM will do the same with all District
Municipalities
• Put it together
• Do the necessary calculations
• Calculate the averages
• Set the standards
• Calculate the deviations and variances
• Give feedback to municipalities, Prov. Tes and rollout
to the Western Cape – then inform NT to follow.
