The marketing environment must first be understood. It includes the following:

1. External and internal factors affect marketing decisions: These factors can include anything from the current economic state, competition in the market, customer behavior, technological advancements, and even the company's own financial and operational capabilities. Understanding these factors can help in making informed marketing decisions.

2. The marketing mix should reflect the environment: The marketing mix refers to the set of marketing tools that a company uses to pursue its marketing objectives in the target market. It typically includes product, price, place, and promotion (the 4Ps). These should be adjusted and aligned according to the current marketing environment to ensure effectiveness.

3. The plan should provide feedback on the plan’s effectiveness: This means that there should be mechanisms in place within the marketing plan to measure and evaluate its performance. This could be through key performance indicators (KPIs), customer feedback, sales figures, etc. This feedback is crucial in understanding whether the marketing efforts are working or if they need to be adjusted.
