Let's take a moment to consider each of them in workplace.

Extrovert: someone who probably has a messy desk; who leaves projects 75% completed then gets distracted by new, 'more exciting' projects; someone who communicates their ideas with enthusiasm and charm; makes instant decisions; hates 'paperwork' and 'dull routines' of life, such as filling in order forms, checking bank statements, etc.; is usually 'fashionably late' to meetings, events and parties (and they love entertaining clients!); always has interesting screen savers.

Amiable: someone who is 'peacemaker' in office; is always striving for a 'win-win' in everything in life; someone who probably isn't terribly ambitious and striving, but is very happy to support and encourage others who are; someone who cannot say "No" very easily and so are probably on every committee going (whether they actually want to be or not); is more likely to make a decision on spot if only to stop you 'hassling' them, otherwise will take weeks to make a decision (if at all, as they prefer others to make decision for them); like to know what others are doing (in case they themselves are doing something inappropriate or foolish).

Analytical: 'GadgetMan' - has multiple PDAs in case one fails; has several computers for same reason; adores punctuality; when they tell you they recently bought something they won't round number up but will tell you to exact dollar and cent how much they paid; loves playing with spreadsheets, charts and projections; will never make a decision on spot; will buy a car based on fuel economy, servicing costs, resell value, depreciation and other factors, never 'because it's a lovely shade of blue'.

Each involves a financial cost for both production and distribution. Are there ways of reducing these costs?

Certainly! eTechnology allows production of words, sound and visual elements to be seamlessly integrated in a dizzying number of ways to achieve different ends. Each element can then be 're-purposed' or re-used in a different way to try new marketing and content delivery approaches.

These are just some of potential new technology outputs that your marketing messages and end-user documents can be distributed through:

* cd-roms

* pdf documents (an electronic format for storing and sending documents which ensures that design integrity of your documents remain intact, irrespective of end-user's computer and printer configuration)

* website

* mobile phone technology such as sms and wap

* PDA (Personal Digital Assistant) devices such as a PalmPilot

* web-tv

The cool thing about many of these distribution mediums is that once cost of producing one item is paid for (such as creating original document), cost of making a thousand or a million copies is negligible.

Imagine saving if you could do away with 80% of printing and posting costs of your expensive Annual Report, allowing instead any interested party to download it from your website, or be sent it via email.
