The collection of non-marketing influences that have an impact on a marketing manager's success in forming and keeping favorable relationships with desirable customers. The overall market environment for a business is made up of the macro environment that consists of broader societal influences and the microenvironment which includes company related influences.
The marketing environment surrounds and impacts upon the organization. There are three key elements to the marketing environment which are the internal environment, the microenvironment and the macro environment. Why are they important? Well marketers build both internal and external relationships. Marketers aim to deliver value to satisfied customers, so we need to assess and evaluate our internal business/corporate environment and our external environment which is subdivided into micro and macro.
The macro environment is less controllable. The macro environment consists of much larger all-encompassing influences (which impact the microenvironment) from the broader global society. The major external and uncontrollable actors that influence an organization's decision making, and affect its performance and strategies. These factors include the economic factors; demographics; legal, political, and social conditions; technological changes; and natural forces.
Again, for Walmart, the wider global macro environment will certainly impact its business, and many of these factors are pretty much uncontrollable. Walmart trades mainly in the United States but also in international markets. For example in the United Kingdom Walmart trades as Asda. Walmart would need to take into account local customs and practices in the United Kingdom such as bank holidays and other local festivals.
