Things To Do (page 182)
3		Filing Clerk. Almost certain to disappear as paperwork is eliminated as data is held electronically. Easy to gain access to specific information using a computer terminal. Copy Typist. Their job will change as they will be required to learn word processing skills. Fewer copy typists will be needed as more staff prepare their own correspondence so there will be fewer jobs. Shorthand Typist. Their job could be at risk due to voice recognition systems that enable dictation straight into a word processing package. Those remaining will need to gain new skills in word processing. Secretary. They will use a word processor and will use a variety of computer software for organising meetings, appointments, etc. Post Room Clerk. Will disappear as more correspondence is sent using email (both inside and outside the organisation). Manager. Their job will not change too much, but they will need to be ICT literate to organise their staff. Accounts Clerk. All the accounts will be computerised so they will need to understand how a computerised accounts package works.

5		Could suggest a system using on-line ordering (e.g. an on-line shop over the Internet such as Amazon, Books On Line(BOL)) Could also look at a system which uses EDI such as a supermarket using communications to order goods from their supplier.
