Final answer:
The failure of the new system to attract more patrons at the bowling center would be discovered during the evaluation phase of systems development. This phase assesses if the objectives like increasing clientele are met and identifies the need for potential system revisions.
Step-by-step explanation:
The failure discovered in the case of the bowling center's new system not attracting more patrons would have been unveiled during the evaluation phase of systems development. This phase is critical for assessing the effectiveness of a system post-implementation and determining if the expected objectives, such as increased clientele, are being met. If the intended goals are not achieved, this points to the necessity of conducting a thorough investigation to identify issues and potentially revising the system's approach.
Visual aids like the one describing the process with phases such as Preparatory Phase, Implementation and Learning Phase, Program Evaluation Phase, and Development of Lessons Learned indicate that proper program evaluation is vital for long-term success. The issue observed indicates that despite having a potentially valuable feature for regular patrons, the expected attraction of new patrons failed, revealing that the system's value proposition may not be aligned with market needs or well communicated.
