Organisations. ExxonMobil

In a hierarchical organisation employees are ranked at various levels within the organisation, each level is one above the other. At each stage in the chain, one person has a number of workers directly under them, within their span of control. A tall hierarchical organisation has many levels and a flat hierarchical organisation will only have a few. In a traditional hierarchy, senior managers make up the board of directors and are responsible for establishing strategy and overall business direction, whilst middle managers have responsibility for a specific function such as finance or marketing.

A traditional hierarchical structure clearly defines each employee’s role within the organisation and defines the nature of their relationship with other employees. Hierarchical organisations are often tall with narrow spans of control, which gets wider as we move down the structure. They are often centralised with the most important decisions being taken by senior management.

In the twentieth century as organisations grow bigger, hierarchical organisations were popular because they could ensure command and control of the organisation. However with the advent of globalisation and widespread use of technology, in the 1990’s tall hierarchical organisations began to downsize and reduce their workforce. Technology was able to carry out many of the functions previously carried out by humans.
