Shirley's time sitting at her desk was interrupted when the human resources manager burst into her office with a particularly vexing problem - customer service ratings had been falling over the last quarter. The human resources manager explained that they were behind on training programs for their workers. Shirley assembled a task force consisting of the brightest minds in the organization and gave them a charge - to look at the previous quarter's issues and to develop training courses over the next 48 months to solve those issues. What roadblock is Shirley confronted with while trying to identify the true problem

Explanation: A roadblock is an obstacle or impediment. Shirley is confronted with conflicting viewpoints as a roadblock while trying to determine the true problem she is faced with. She probably holds opposing or contradictory perspectives to that of the Human Resource manager which explains the reason for assembling a team to specifically " look at the previous quarter's issues" and "to develop training courses over the next 48 months to solve those issues". Conflicting viewpoints is one of the problems to quantitative analysis which is a scientific approach to decision making. Others include: outdated solutions, understanding the model, beginning assumptions etc.
