Chapter 7 Flashcards
Why is it important to analyze the current system before designing a new one?
Before a new system can be designed, the current system needs to be analysed.
Describe the methods used to analyze existing systems, including observation, interviews, questionnaires, and document examination.
Observation, interviews, questionnaires and the examination of documents are used to analyse existing systems.
How do validation routines play a role in input design to ensure acceptable input?
Input designs uses validation routines to check that the input is acceptable.
- Explain the significance of output formats in the context of system design.
Output formats describe how screen and printed reports will appear.
What is the purpose of file and data structures in identifying items of data for input, processing, and storage?
File and data structures must identify the items of data that will be input, processed and stored.
Discuss test strategies, test plans, and test designs in the context of system testing.
Test strategies specify how and when testing will take place. Test plans list all of the tests that will be carried out.
What are the different methods of system implementation, and when is each method suitable?
Implementation is the changeover from the old to the new system; there are different methods of implementation such as: direct changeover, phased implementation, pilot running, parallel running.
Explain the role of documentation in implementing a new system.
Documentation consists of technical and user guides.
How is the success of a new system evaluated concerning meeting identified requirements?
Evaluation discusses how successful the new system meets the identified requirements.
