問(wèn)題：Which TWO of the following statements about an organisation chart are not true?
　　A. An organisation chart can confuse internal communications within a business.
　　B. An organisation chart can improve employees' understanding of their role in a business.
　　C. An organisation chart can indicate functional authority but not line authority within a business.
　　D. An organisation chart provides a summary of the structure of a business.
　　答案：The correct answers are:
　　An organisation chart can confuse internal communications within a business  and
　　An organisation chart can indicate functional authority but not line authority within a business
　　解析：Rationale: Line authority can easily be shown on the organisation chart.
　　Pitfalls: You may have hesitated if you didn't know the difference between functional authority (where an expert department has authority over the activities of other departments in the areas of its expertise eg the HR department setting recruitment policy for the sales and production departments) and line authority (direct authority flowing down the chain of command). However, you only needed to know the meaning of line authority to see that the statement was untrue.
　　Ways in: You may have paused to ask whether an organisation chart can improve or confuse internal communications, but it does improve in one key way: by highlighting the length and complexity of lines of communication between people who need to co-ordinate their work.
