A common method of assessing a firm's macro-environment is via a PESTLE (Political, Economic, Social, Technological, Legal, Ecological) analysis. Within a PESTLE analysis, a firm would analyze national political issues, culture and climate, key macroeconomic conditions, health and indicators (such as economic growth, inflation, unemployment, etc.), social trends/attitudes, and the nature of technology's impact on its society and the business processes within the society. 
One of the limitations of the 4Ps approach is its emphasis of an inside out-view.  An inside-out approach is the traditional planning approach where the organisation identifies its desired goals and objectives, which are often based around what has always been done.

In contrast, an outside-in approach first seeks to understand the needs and wants of the consumer.

Place refers to the distribution of the product. Key considerations include whether the company will sell the product through a physical storefront, online, or through both distribution channels.

This refers to how the product gets to the customer; the distribution channels and intermediaries such as wholesalers and retailers who enable customers to access products or services in a convenient manner. This third P has also sometimes been called Place or Placement, referring to the channel by which a product or service is sold (e.g. online vs. retail), which geographic region or industry, to which segment (young adults, families, business people), etc. also referring to how the environment in which the product is sold in can affect sales.
