An organization has been expanding, but it has been having trouble effectively tracking and reviewing routine transactions during the expansion. The organization believes that the current transaction processing system is insufficient for the new level of business. The organization is currently determining whether the newly developed system behaves as planned. Which step of the systems development process is the organization in?

In the design phase, the focus is on creating the architecture of the system based on requirements gathered in earlier phases. This involves outlining how the system will operate but does not include evaluating whether the system works as intended, which is a critical function of the testing phase.

During the programming phase, developers write the code for the system based on the design specifications. While this step is crucial for building the system, it is not concerned with assessing its behavior or functionality, which occurs later in the testing phase.

The conversion phase involves transitioning from the old system to the new one. This step includes implementing the new system in a live environment but does not encompass the process of verifying that the system behaves correctly, which is the primary goal of testing.
