System Life Cycle Quiz

What are the characteristics of the research method of observation?

• Limited sample size, biased results, time-consuming

• Large sample size, unbiased results, cost-effective

• Limited sample size, unbiased results, cost-effective

• Large sample size, biased results, time-consuming

What is the purpose of analysing the current system?

• To identify the inputs, outputs, and processing of the current system

• To design file/data structures and input/output formats

• To test the system before implementation

• To document the system specifications

Which validation routine checks if the data is within a specified range?

• Range check

• Character check

• Length check

• Type check

What is the purpose of test data in system development?

• To evaluate the efficiency of the solution

• To identify any limitations and necessary improvements to the system

• To compare the solution with the original task requirements

• To test the system before implementation

Which method of implementation involves running the new system alongside the old system?

• Direct changeover

• Parallel running

• Pilot running

• Phased implementation

What is included in technical documentation?

• Purpose of the system, limitations of the system, hardware and software requirements

• Program listing, program language, program flowcharts/algorithms

• File structures, list of variables, input format, output format

• Sample runs/test runs, validation routines

What is the purpose of user documentation?

• To evaluate the efficiency of the solution

• To identify any limitations and necessary improvements to the system

• To provide instructions on how to use the system

• To test the system before implementation

What should be evaluated in a solution?

• The ease of use of the solution

• The appropriateness of the solution

• The efficiency of the solution

• All of the above

What is the purpose of comparing the solution with the original task requirements?

• To evaluate the efficiency of the solution

• To identify any limitations and necessary improvements to the system

• To test the system before implementation

• To ensure the solution meets the initial requirements

What are the advantages of direct changeover as a method of implementation?

• Allows for easy rollback to the old system, minimal disruption

• Allows for gradual transition, reduced risk

• Allows for testing of the new system alongside the old system

• Allows for parallel running of the old and new system
