Organisational Structure 
It is a structure that depends on the organisation's objectives and strategy. The arrangement or pattern of jobs within an organisation is shown in the organisational chart. It also shows a hierarchy of people who have different level of responsibility and tells you the character of an organisation and the values. Hence, people who are getting into a new job in a organisation are encouraged to know and understand their organisational structure. Any operating organisation has its organizational structure in order to operate efficiently.

Types of Organisational Structure 

Bureaucratic Structures

• Pre-bureaucratic Structure - The structure is centralised and appears like hierarchy. There is only one key decision maker and most communication is done by one-on-one conversations. It is usually used by small organisations. 
• Bureaucratic Structure - This structure has a certain degree of standardisation. They are better suited for more complex or lager scale organisations, usually adopting a tall structure. 
• Post-bureaucratic Structure - Post-bureaucratic structure inherits the strict hierarchies. 

Functional Structure

This structure is grouped based on functional areas as marketing, research and development and finance. Employees with same skills and knowledge are grouped together by functions  performed. However, different functional groups have no chance to communicate and caused decreasing flexibility and innovation. 

Line Structure 

It is perhaps the simplest organisational structure. Line organisational chart shows the relationships and relative ranks of its parts and positions or jobs. It can be split into smaller charts for separate departments when an organisational chart grows too large. 

Matrix Structure 

Matrix Structure is the combination of functional and divisional structure. It provides flexibility to respond quickly to a customer needs by allowing employees from different departments to come together temporarily to work on special project teams.

Organisational Chart in Google Company 

The organisational chart used in google is a regular functional structure and a little combine with multidivisional structure, with management positions specialised by value chain activity. All employees are divided into groups according to what they can do that helps the company operating well. The structure above clearly shows within each top-level activity, there is a multidivisional structure where the small business unit is are divided. This form of structure is applied well in google because it gives the small business units the flexibility to innovate at the same time it is centralized. Google has grouped the workers as though into many small start-up companies within the division to match with its own management style, laissez-faire. 

My opinion: 

I think Google functions well using functional structure as they are applying laissez-faire style. Thus, every worker does their own jobs and later combine with others' and then inform the headquarter. I would not change anything if i were in charge because I think it works good in its own ways.
