System Life Cycle and Data Collection

The video tutorial by Camilla covers Chapter 7 of the IGCSE ICT syllabus, focusing on the system life cycle. It explains the phases of the cycle: analysis, design, development and testing, implementation, documentation, and evaluation. The tutorial discusses methods for data collection, such as questionnaires, interviews, observation, and examining existing manuals. It also covers design and verification techniques, validation checks, and testing processes. Various implementation strategies are explored, including direct, pilot, parallel, and phased approaches. The importance of technical and user documentation is highlighted, along with the evaluation process to ensure system effectiveness.

What is the first phase of the system life cycle?

• Design

• Analysis

• Evaluation

• Implementation

Which method of data collection involves directly observing users?

• Questionnaires

• Interviews

• Observation

• Technical Documentation

What is a drawback of using questionnaires for data collection?

• Inability to observe user behavior

• Lack of detailed responses

• Time-consuming

• Limited reach

In the design phase, what is the purpose of verification?

• To ensure data meets criteria

• To check for data entry errors

• To observe user interaction

• To update system documentation

What type of data is considered 'extreme'?

• Data already known

• Data on the border of acceptability

• Data outside acceptable range

• Data within normal range

Which implementation method involves running both old and new systems simultaneously?

• Pilot

• Phased

• Direct

• Parallel

What is the purpose of user documentation?

• To guide users in operating the system

• To assist developers

• To evaluate system performance

• To provide technical details

During which phase is the system's performance evaluated?

• Analysis

• Evaluation

• Design

• Implementation

What is a 'pilot' implementation?

• Testing in a single branch

• Running both systems together

• Gradual introduction

• Immediate switch to new system

What is included in technical documentation?

• Installation instructions

• User guides

• System flow charts

• Troubleshooting tips
