2. P1
Describe the potential prompts that initiate the installation of new or upgraded software
Problems with the existing system.
Unstable software that leads to system crash
Software no longer supported by manufacturer – so no user support & updates for it.
Security issues with the current software – leading to malicious attacks.
Current software incompatible with the new operating system.
Additional functionality required: such as strong parental control that was lacking in Windows XP and that is now available in Windows Vista or 7.
Another example upgrading your antivirus program to a full internet security suite that will include firewall and anti spyware.

3. New hardware requiring new or upgraded software
New hardware requiring new or upgraded software. What is the software called to install when you attach a new hardware.
To fix bugs- that will reduce the system to crash or hang.
Company Policy: a company may have a policy that only certain software can only be installed. When new installations and upgrades will be carried out

4. Lets brainstorm and check the internet for some answers:
M1 Explain the advantages and disadvantages of installing and upgrading software
Lets brainstorm and check the internet for some answers:
Look at the prompts to get further ideas:
Think about cost, any restrictions, security, stability, training, usability, performance

5. D1 – Justify to the managers why installing their anti virus software would be advisable
Just because there is a prompt for change, it doesn’t mean that an organisation will agree to the change going ahead.
Installing & upgrading software is often expensive
cost of the software
Additional cost such as training, ‘down-time’ needed to install the software.
Therefore it is important to have a good business case showing that the benefits outweighs the costs of the new software or upgrade.
Benefits such as – greater efficiency, improved systems security.
Use the factors you have learnt from other units on how viruses and worms can affect the operations of a business to support your answer.

6. P2 – Describe the potential risks of installing or upgrading software
‘Down-time’ – when the current system will be inactive while installing
Incompatibility issues : imagine what would happen to your existing files when you switch from Windows to Linux

7. How would the above factors affect the business operations?
D2 – Evaluate the potential risks of installing and upgrading software and explain how the risks could be minimised
Down-time – careful planning would be required. Think about the best time to install. What kind of resources would be stopped when you install a system on a server for example?
Incompatibility issues: switching OS, upgrading Ms word 2003 – 2007 files could not be opened.
How would the above factors affect the business operations?

8. D2 – How risks can be minimised?
Backups
Installing at low risk times
Incremental installation: you can install on a few Pc’s, evaluate and test for any problems, then gradually installing the rest – benefits, the business can still run their operations.
