How have organizations evolved into vertical silos over the years? What impact does this have on information sharing?

What will be an ideal response?

Since the late 1960s, researchers found that organizations divided up responsibility in hierarchical layers. These layers were associated with strategic planning, management control, and operational control. These layers in the organization helped to define the business roles at each level; i.e. CEOs focused on strategic planning, managers focused on management control, and line-level people were involved in day-to-day operations. With respect to information sharing and systems, each layer has different information and reporting needs, so they typically had totally separate systems to support their individual needs. These systems were not oriented towards sharing information up and down the vertical silo or hierarchy.
