Some organization is considering implementing a new computer system.
The management is comparing phased conversion and direct changeover as methods of implementation.
State one type of testing that involves users.
-
User acceptance testing
1 mark -
Beta testing
1 mark
Identify three consequences of inadequate testing.
-
Can lead to software which is not appropriate for the purpose it was intended/can lead to the system not meeting user requirements
1 mark -
Can lead to (undiscovered) bugs in software/errors in the system
1 mark -
Can lead to end user dissatisfaction
1 mark -
Can lead to reduced (employee) productivity
1 mark -
Can lead to decreased reliability of the organization

Evaluate these two methods of implementation.
Method #1 - Direct changeover
- Is the cheapest and quickest/the old system is completely switched for the new one
1 mark - This is straight forward but also the most risky / nothing to fall back on
1 mark - No need to keep data duplicates
1 mark - It allows the organization to change the system when most convenient
1 mark - The employees have very little time in order get use to the new system as the change is instantaneous
1 mark - There is a period of time when neither systems are operational
1 mark
Method #2 - Phased changeover
- Method where the old system is still in use but parts of the new system or modules are introduced, involves bringing in the new system one step at a time
1 mark - Less risky than direct changeover; less risky that the whole system will go wrong/if something happens, it will only affect the specific part
1 mark - Takes a lot of time
1 mark - Employees have enough time for training/to get use to the new system / are introduced to the changes in small stages
1 mark - Employees/users could ask for changes which then hold up the installation of the next phase which helps improving the system
1 mark
Identify two organizational issues related to the implementation of the new system.
-
Need for employee training/retraining on the new system
1 mark -
Changes required to organizational policies, procedures, and processes to align with the new system
1 mark -
Potential resistance to change from employees used to the old system
1 mark -
Need for effective communication and change management strategies during implementation
1 mark -
Budgeting and resource allocation for the implementation project
1 mark
Discuss the social and ethical issues associated with the introduction of a new computer system.
- Personal/professional development of all employees must be considered
1 mark - Physical safety (of all users)
1 mark - Ergonomic standards (human-computer components)
1 mark - Human dignity of all users
1 mark - The new system might be designed to replace some staff
1 mark - Code of ethics (system resources should not be used without approval)
