7. Hold USER-CONFIDENCE

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OUT-OF-DATE INFORMATION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

A teacher asks Mr Jones for a printout of the grades achieved by students in the GCSE examinations. Mr Jones produces the following:-

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.
