Managers analyze customer feedback from "their" perspective. Often this view is touchpoint or function specific. Their job is to extract actionable insights that enable them to improve their own department’s performance. Your job, as a CX professional, is to analyze the whole customer experience .
It is easy to define the customer journey from top down: you plot the different touchpoints and set them in chronological or some other logical order. It is much harder to monitor and measure how different touchpoints are performing.
Organizational layers like to consume information in different ways. Executives like static reports with KPIs. Managers need a dashboard with signals about problems or opportunities and the ability to dig deeper to find out the root cause for those issues. Frontline employees just want to get their jobs done. Analysts need to dig deep to detect weak signals, emerging trends, and do predictive analytics. That is why the reporting tools and the level of information in them need to be different for each organizational layer.
