7 Systems Lifecycle

What is the first stage in the Systems Life Cycle?

• Implementation

• Development

• Analysis

• Design

Which analysis technique involves observing the current system to find out how it works?

• Interview

• Questionnaires

• Collecting Documents

• Observation

What is the purpose of User Documentation?

• To help technical maintainers understand the system

• To assist users in understanding and using the system

• To outline the required improvements for the new system

• To troubleshoot errors in the system

Which validation technique checks if the data entered is in the correct range?

• Type Check

• Length Check

• Range Check

• Presence Check

What is the advantage of Parallel Running during system implementation?

• If the new system fails, the old system is still available

• Tasks will be duplicated as data is inputted into both systems

• Training can take place in one department at a time

• Costs are reduced as only one system is being used

What is the purpose of Evaluation in the Systems Life Cycle?

• To compare the solution with the original task requirements

• To identify any limitations and necessary improvements to the system

• To evaluate the users' responses to the results of testing the system

• All of the above

Which type of data includes data on the boundaries of the range or at the limits of acceptability?

• Outlier

• Extreme

• Normal

• Abnormal

What is the purpose of Technical Documentation?

• To assist users in understanding and using the system

• To troubleshoot errors in the system

• To outline the required improvements for the new system

• To help technical maintainers understand the system

Which stage involves creating the file structure, setting specific data types, and developing validation techniques?

• Implementation

• Analysis

• Design

• Development

What is the disadvantage of Direct Changeover during system implementation?

• Costs are reduced as only one system is being used

• Tasks will be duplicated as data is inputted into both systems

• If the new system fails, the old system is not available to fall back to

• There may not be enough time to provide training to employees
