|
my favourite program on the TELE and VIDEO is LOST, it makes me want to RETRAIN for a NEWJOB as an actor
|
|
|
‘Discuss in detail the impact new ICT systems could have on job and work patterns’ point 1
|
Teleworking - working from home using computer networks saves on transport / environmental costs
|
|
|
‘Discuss in detail the impact new ICT systems could have on job and work patterns’ point 2
|
Video conferencing - allows remote meetings - saves time in travel which can be used more productively
|
|
|
‘Discuss in detail the impact new ICT systems could have on job and work patterns’ point 3
|
Lost jobs - unskilled manual jobs lost such as filing clerks + Call centres have caused many people to lose jobs e.g. bank clerks as they have been moved abroad where labour is cheaper leading to ICT 'sweat shops'
|
|
|
‘Discuss in detail the impact new ICT systems could have on job and work patterns’ point 4
|
Retraining – need to acquire new skills to use databases /spreadsheets / e-mails / programming etc e.g. wages clerk now uses specialist software
|
|
|

|
New jobs - systems analysts, programmers needed to write applications or tailor DBMS for users
|
|
|
‘Name 4 alternative changeover strategies a company could use’
|
Direct, Parallel, Phased and Pilot
|
|
|
Define Direct Changeover
|
Direct changeover – stop using the old system one day and start using the new system the next day
|
|
|
Define Parallel Changeover
|
Parallel changeover – Old ICT system is run alongside the new ICT system for a period of time until all the people involved with the new system are happy it is working correctly
|
|
|
Define Phased Changeover
|
A module at a time can be converted to the new system in phases until the whole system is transferred
|
|
|
Define Pilot Changeover
|
This method is ideal for large organisations that have lots of locations or branches where the new system can be used by one branch and then transferred to other branches over time
|
|
|
Advantage of Direct changeover
|
"Requires fewer resources (people, money, equipment) and is simple,
|
|
|
Disadvantage of Direct changeover
|
Element of risk particularly if the hardware and software are cuttingedge . If the system fails then it can be disastrous to the business
|
|
|
Advantage of Parallel changeover
|
Advantage - Used to minimise the risk in introducing a new ICT system . The old system is then abandoned and all the work is done entirely on the new system.
|
|
|
Disadvantage of Parallel changeover
|
Disadvantage - Lots of unnecessary work (as the work is being done twice) and is therefore expensive in people’s time . It also adds to the amount of planning needed for the implementation
|
|
|
Advantage of Phased conversion
|
Advantage - IT staff can deal with problems caused by a module before moving on to new modules
|
|
|
Disadvantage of Phased conversion
|
Disadvantage - Is only suitable for systems consisting of separate modules.
|
|
|
Advantage of Pilot conversion
|
Advantage - Implementation is on a much smaller and manageable scale.
|
|
|
Disadvantage of Pilot conversion
|
Disadvantage - Takes longer to implement the system in all the branches.

what is the mnemonic for reasons that users become dissatisfied with systems
|
my new REQUIREMENT foolish boy is that you CHANGE and stop being a FAILURE, when i look at you INTERFACE its like looking at a TESTCRASH dummy doing a poor PERFORMANCE
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 1
|
The full range of user requirements has not been met, so the system does not live up to user expectations.
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 2
|
"Change in business needs means system cannot deal with new demands placed on it.
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 3
|
Failure to supply users with the information they require.
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 4
|
User interface causes many user problems with increased help-desk use.
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 5
|
"Problems with the software or system crashing owing to lack of rigorous testing.
|
|
|
‘why might users become dissatisfied with their ICT system?’ reason 6
|
Network performance or speed of access to stored data becomes unacceptable as more users are added to the system
|
|
|
what is the mnemonic for ways the systems a sytems analyst can gather information about a system
|
lets have an INTERVIEW to OBSERVE the RECORD INSPECTION of your QUESTIONNAIRES - and see if you are rubbish.
|
|
|
‘Describe the ways in which a Systems Analyst can gather information about an existing system’ method 1
|
Interviews – interviews with managers normally reveal how the departments work and any current problems. Normally will say how they want the new system to work and what information they want. Operational staff can supply fine detail on how the current system works. Very time consuming. Needs skilled interviewers to get the correct information out of people.
|
|
|
‘Describe the ways in which a Systems Analyst can gather information about an existing system’ method 2
|
Observation ( inspect/ look at / shadow) – sit and watch how somebody does their job at present.Can be time consuming and span several weeks before you can see everything.
|
|
|
‘Describe the ways in which a Systems Analyst can gather information about an existing system’ method 3
|
Inspection of records – studying the paper based information produced by the company at the moment. Allows one to see what information is currently held and the way it is communicated between different departments or customers and the company. Documents include organisational charts, manuals, reports, minutes of meetings and all documentation.
|
|
|
‘Describe the ways in which a Systems Analyst can gather information about an existing system’ method 4
|
Questionnaires – ideal way to collect information as you do not have to waste time talking to people and can stick to the important points without digressing. Economical to reproduce and distribute. Problem is that people forget to fill them in and hence an incomplete picture. Response rate from posted surveys is often poor. Respondents may misunderstand some of the questions. Cost involved in hiring people to ask others to fill in questionnaires and collect results can be significant.

What is the mnemonic for the contents of a feasibility report?
|
I REQUIRE you to solve your PROBLEMS with the COST/BENEFIT of your body's hardware ... would an OPERATION lead to POTENTIAL IMPROVEMENTS .... I CONCLUDE
|
|
|
‘Describe the purpose of a Feasibility Study/Report
|
A feasibility report is the summary of an initial investigation to look at the likelihood of being able to create a new system with stated aims and objectives at reasonable cost. The document is used by senior managers to assess whether it is worth continuing with the project.
|
|
|
What are the contents of a Feasibility Study/Report 1
|
Identify user requirements and their aims and objectives and any problems noted
|
|
|
What are the contents of a Feasibility Study/Report 2
|
Identification of problems with the current system.
|
|
|
What are the contents of a Feasibility Study/Report 3
|
Cost benefit analysis of the new system / Consider cost implications in terms of human resources, consultancy fees, training requirements, hardware upgrading, payment to third party providers, licences and fees, etc
|
|
|
What are the contents of a Feasibility Study/Report 4
|
Details of existing hardware and software. / Consider technical issues including: do they have equipment to implement; do they have in-house technical expertise; are there compatibility issues with existing systems
|
|
|
What are the contents of a Feasibility Study/Report 5
|
Consider operational issues including: impact on day to day work; what training will be required; will re-structuring be necessary; other logistic and practical issues
|
|
|
What are the contents of a Feasibility Study/Report 6
|
Potential improvements / benefits on the new system
|
|
|
What are the contents of a Feasibility Study/Report 7
|
Conclusions /Is it worth proceeding?
|
|
|
Name 3 Types of system maintenance
|
Perfective, Adaptive and Corrective
|
|
|
What is the purpose of Perfective Mainenance
|
Perfective maintenance – improving the performance of the software (1).
|
|
|
Give an example of Perfectivce Maintenance
|
Example: Configuring the network management software to improve performance such as improving access times to data, speed at which reports are produced, etc.
|
|
|
What is the purpose of Corrective Maintenance
|
Corrective maintenance – bugs in the software which were not discovered during testing may need correcting.
|
|
|
Give an example of Corrective Maintenance
|
Example: A piece of software may crash when being used with another piece of software Software may present a security risk which needs correcting. Problems with reports not being printed out properly.
|
|
|
What is the purpose of Adaptive Maintenance
|
Adaptive maintenance – software may need to be changed owing to the changing needs of the business or organisation .
|
|
|
Give an example of Adaptive Maintenance
|
Example: Software may need altering so that it is more flexible in supplying the managers with information which was not envisaged at the time of development. Or. Changes to values such as the percentage rate of VAT or changes to income tax rates will result in changes to the software.
