The System Life Cycle & System Analysis

Explanation
The Problem Definition is the first step of the System Lifecycle. The Feasibility Study follows it.

During the Feasibility Study a report is drawn up listing things like: whether the system can be developed, how much it will cost and how long it will take to develop.

Explanation
Maintenance may be necessary because the user needs new functionality in his program or new technology (e.g. barcode reader) becomes more available and affordable. Besides, no matter how much you test a system, it can still have bugs.

Explanation
The feasibility study is a process that assesses the practicality and viability of a project. It includes various aspects, one of which is preparing a report that evaluates the economic feasibility of developing the system. This report helps in determining whether the project is financially viable and if the benefits outweigh the costs. Therefore, the statement is true as the feasibility study indeed involves the creation of a report regarding the economic feasibility of the system.

Explanation
System design is indeed the process of developing a system, which involves creating flowcharts, diagrams, and other visual representations to outline the structure and functionality of the system. This step is crucial in the overall system development lifecycle as it helps in identifying the requirements, designing the architecture, and planning for the implementation of the system. Therefore, the statement "System design refers to the development of the system, that is the production of flowcharts etc." is true.

Explanation
In the direct changeover method, the old system is stopped as soon as the new system is introduced. So if something goes wrong with the new system there is nothing of the old system to fall back on.

Explanation
The parallel running changeover method refers to a strategy where both the old and new systems are run simultaneously during a system transition. This approach may incur additional costs due to the need for duplicate resources and the potential for training and maintenance expenses. However, it ensures that data is not lost during the changeover process, as both systems are operational. Therefore, the given statement is true.

Explanation
During System Analysis, the manual system is studied in detail to help the System Analyst figure out what the new system will need.

Explanation
If the system is only tested at the very end, fixing error may be very expensive.

Explanation
There is always a possibility that maintenance is required at some point.

Explanation
The statement is true because a system analyst is responsible for drawing up a test plan for the new system. A test plan outlines the objectives, scope, and approach for testing a new system to ensure that it meets the desired requirements and functions properly. The system analyst, being responsible for analyzing and designing systems, plays a crucial role in creating a comprehensive test plan that covers all aspects of the new system's functionality and performance.
