1. ACCURATE
Imagine what customers would say if their electricity bill said they owed £20,000 for this quarter’s electricity!!
INACCURATE INFORMATION
2. RELEVANT
Imagine what customers would say if their electricity bill said that the next-door neighbour’s bill was for £65 for this quarter’s electricity!!
IRRELEVANT INFORMATION
3. UP-TO-DATE
What would you say if your parent/guardian had a letter from the County Council asking which Primary School you will be attending from September!
OUT-OF-DATE INFORMATION
4. COMPLETE
You send a very important job application form – but it’s received too late, even though it was sent first class. You are pretty cheesed off as these jobs only come up once in a blue moon.
INCOMPLETE INFORMATION
You are later told that you had forgotten to put the postcode on the letter!! DOHHH!
5. UNDERSTANDABLE

UNDERSTANDABLE?
6. TARGETED
An entrepreneur car sales assistant manages to get hold of a list of names and addresses of prospective customers which he has been told are “in the market” for a new motor. He spends many hours preparing leaflets, mail-merge letters and other sales materials then sends these materials to each of the customers on his list. (Very, very expensive!!)
Next day – he is called into the office and given the sack!
The list (he had obtained) was in fact a list of pupils starting in the primary school next September!!
Targeted – I don’t think so!
7. HOLD USER-CONFIDENCE
Government scientists in Japan are saying that the nuclear facilities struck by the earthquake and tsunami are safe.
The exclusion zone around the first facility was increased to 10km – then 20km ……..
Many Japanese citizens in the area have left for other parts of Japan!
User-Confidence level = 1/10 maybe?
DATA OVERLOAD??Sometimes too much information causes overloads – it just
cannot be processed quickly enough to make sense.
