The internal environment has already been touched upon by other lessons on marketing teacher. For example, the lessons on internal marketing and also on the functions within an organization give a good starting point to look at our internal environment. A useful tool for quickly auditing your internal environment is known as the Five Ms which are Men, Money, Machinery, Materials and Markets. Here is a really quick example using British Airways. Looking internally at men, British Airways employees pilots, engineers, cabin crew, marketing managers, etc. Money is invested in the business by shareholders and banks for example. Machinery would include its aircraft but also access to air bridges and buses to ferry passengers from the terminal to the aircraft. Materials for a service business like British Airways would be aircraft fuel called kerosene (although if we were making aircraft materials would include aluminium, wiring, glass, fabric, and so on). Finally markets which we know can be both internal and external. Some might include a sixth M, which is minutes, since time is a valuable internal resource.
