This is a sample of what I have been doing at TAFE, I earned a distinction for this J (work effectively in an IT environment).

Exercise on Policy and Procedures

1. Imagine you are working in a Space Exploration station in Woomera SA in the IT section writing software to control a space ship to land a manned expedition to Mars.

(a) What sort of policies and procedures would you put in place to minimise errors and why?

(b) What security would you put in place and why?

(c) What backup procedures would you implement and why?

(d) What other company policies do you think this organisation may have?

Place your answer here: A:Error minimisation: Error minimisation needs to occur at all stages in processing.the most important stage for error detection is at the point of input.Many checks to be placed at the data input stage, from easy to read input forms to checks within the software itself.(Eg, forms to be designed in such a way that data input is facilitated, moving from left to right, top to bottom.) Software will check for valid data. Software must be checked for accuracy.(Eg, software must be tested with the same hardware as it will be used with on the mission. Also must have data redundancy and duplication, software redundancy and duplication, and hardware redundancy and duplication. Pt2:As this mission would involve travailing millons of Kms through space and have a time frame of some two years, software systems (and hardware) have to be rugged, reliable and durable not to mention accurate as for example even the smallest navigation error would mean missing the target altogether. A problem in space or on the surface of Mars could easly be life threatening. For example NASA recently sent an unmaned probe to Mars however, something went wrong and contact was lost a critical time (during decent) witch caused the asumed destruction of this spacecraft.NASA blamed cost cutting for failure of the mission.(Sounds like software and/or hardware failure.) B.I would use data encription,(minimum spec:128 bit encription,just about impossible to hack in to)video/voice reconition of authorised users,(before they even get into the room !) secure passwords witch change each time a user acesses the system.Armed security gards(with dogs) partrolling the entire site day and night,burguler alarms. Pt2:

2. Now imagine you are working for a small store in your town, say a Surf Shop or Sports Store and part of your job specification is that you look after the business' PC. The manager wants to put on a fashion parade and asks you to set up a database of people to invite to the fashion parade.

 

(a) What sort of policies and procedures would you put in place to minimise errors and why?

(b) What security would you put in place and why?

(c) What backup procedures would you implement and why?

(d) Do you think there are any privacy issues involved here?

(e) What other company policies do you think this organisation may have?

 

Place your answer here: A:placed at the data input stage, from easy to read input forms to checks within the software itself.(Eg, forms to be designed in such a way that data input is facilitated, moving from left to right, top to bottom.) Software will check for valid data. Software must be checked for accuracy.
