Explain why businesses have internal organisational structures and different job roles and responsibilities.

Direct answer

In a functional structure, staff are grouped by specialist functions such as marketing, development and customer support. This grouping encourages deep expertise within each function but can create vertical communication channels. Information often flows up and down the hierarchy, which may slow decision‑making when cross‑functional coordination is required. However, clear reporting lines reduce ambiguity about who is responsible for what, improving accountability.

How it works

The analysis shows that while functional structures enhance specialist knowledge and clarity of responsibility, they can also create silos that hinder rapid, cross‑department communication.
