Sources of Information

Internal Source

Information that comes from within an organisation, such as financial reports, data analysis or employee surveys.

External Source

Information that comes from outside of an organisation, such as government reports, financial data of competitors or price lists from suppliers.

Types of Data

Primary Data

Data that has been created and collected by yourself or another employee within an organisation. For example, interviews or questionnaires sent within the company.

Secondary Data

Data that has been created and collected by someone outside of the organisation, such as national census data collected by the government or surveys taken by a competitor. Some secondary data may need to be purchased.

Qualitative Data

This is descriptive data, often composed of text, that can be observed but not measured. For example, survey responses where customers are asked why they visit a particular shop.

Quantitative Data

This is measured data, often in the form of numbers, percentages or statistics. For example, survey responses of the amount of time it takes to reach a shop.
