Planning and System Installation

Understanding the purpose and needs of a system before designing it, involving questions like where, when, how, what, who, and why.

Implementation Comparison

Differentiating between Local (on specific computers) and Remote (accessible over the internet) software, with examples like SaaS.

Compatibility Issues

Problems like software differences, data format issues, and varied standards when integrating new systems with existing ones.

Installation Processes

Methods like Direct Changeover, Parallel Running, Pilot Running, and Phased Conversion for installing a new system.

Data Migration Problems

Issues like incompatible file formats, international conventions, and incomplete transfers when transferring data between environments.

Types of Testing

Including Static Testing, Dynamic Testing, Alpha Testing, Beta Testing, and Automated Testing to ensure a computer system works without issues.

User Documentation

Various types like Help files, Online Support, and Printed manuals that explain how to use a system's functions to users.

User Training

Methods such as Self Instruction, Formal classes, and Remote training to help users familiarize themselves with a system or software.

System Backup

Understanding data loss causes like hardware malfunctions, human errors, software corruption, viruses, and natural disasters, and how to prevent them.

Software Development

Involves processes like product release, updates, and patches to ensure software quality and address user issues effectively.

Release Management

Involves Continuous delivery, Agile Software development, and DevOps to plan, schedule, and control software releases for smooth deployment and operation.
