The Marketing Environment

The term "marketing environment" relates to all of the factors (whether internal, external, direct or indirect) that affects a firm's marketing decision-making/planning. A firm's marketing environment consists of three main areas, which are:

• The macro-environment, over which a firm holds little control
• The micro-environment, over which a firm holds a greater amount (though not necessarily total) control
