Implementation of Systems
It involves coding, testing, creating necessary hardware, and providing training to end-users.
System Testing
A holistic approach to testing the application. Types include Recovery Testing, Security Testing, Stress Testing, Performance Testing, Response Testing, Usability and Documentation Testing.
- Alpha Testing: Carried out by the customer at the developer site in a controlled environment.
- Beta Testing: Carried out at one or more customer sites by end-users.
Converting Old System to the New System:
Can be performed in several ways depending on system criticality and related issues:
- Direct Conversion: Old system is shut down, and the new system starts.
- Pilot Conversion: New system is installed at a single pre-decided location.
- Parallel Conversion: Old system runs alongside the new system until management and users are satisfied.
- Phased Conversion: Different sub-systems of the new system are used in conjunction until the whole new system is converted.
System Analysis and Design Interview Topics for Freshers
System Analysis is the “what” before the “how” in system design. It provides the essential roadmap for crafting a system that is both effective and efficient in solving the intended problem. “Imagine you’re building a dream house. You wouldn’t start hammering nails without a detailed blueprint, right?”The same goes for software development.”
System analysis is the blueprint, while system design translates it into the actual system.
