Final answer:
It is true that the System Development Life Cycle may be repeated if monitoring shows the system is not producing the desired results, such as when design decisions fail to meet customer needs, testing reveals design weaknesses, or when a spiral design process is employed.
Step-by-step explanation:
The system development lifecycle (SDLC) is designed to ensure that information systems meet the needs and requirements of an organization or its customers. It is true that the SDLC may be repeated if monitoring activities reveal the system is no longer producing the desired results. This could happen for a variety of reasons. For instance, poor design decisions made early in the process can lead to a situation where it's impossible to develop a design that fully meets customer needs. Additionally, during the testing phase, if weaknesses are found in the design, these need to be addressed, which may require revisiting earlier stages of the SDLC. The spiral design process is one method that inherently includes iterative development and refinement.
Furthermore, part of the SDLC includes creating documentation such as a user's manual, which helps in communicating processes and results to end-users. Posting designs on a website could be part of the larger communication strategy but is not specifically a phase of the SDLC. The process of SDLC is considered complete when there are no further improvements to make, which in practice often means the system has met its objectives sufficiently for the current business environment and meets current customer needs.
