Question 7

The cutover phase of the SDLC involves the day-to-day operation of the system,making modifications to improve performance and correcting problems.

Accepted Answer

The cutover phase of the SDLC involves the implementation of the system and transitioning from the old system to the new system. The day-to-day operations, modifications, and problem corrections occur in the maintenance phase of the SDLC.

Question 8

The SDLC provides a general outline of how an information system evolves.

Accepted Answer

The SDLC (Software Development Life Cycle) provides a systematic approach to the development of an information system, typically consisting of several phases such as planning, analysis, design, implementation, and maintenance. It is a general outline that helps to ensure that the system is developed in a structured and organized manner, focused on meeting user requirements and delivering a high-quality product.

Question 9

Many projects fail because of constant,unmanaged demand for changes,a phenomenon often referred to as feature creep.

Accepted Answer

Feature creep is a well-known phenomenon in project management where stakeholders keep adding new features or changing the existing ones, without proper planning or prioritization, leading to project delays, cost overruns, and ultimately project failure.

Question 10

Direct conversion avoids some of the risk of parallel conversion because the old system remains in service while some or all of the new system is activated.

Accepted Answer

The answer of Direct conversion avoids some of the risk...
