A successful marketing plan involves integrating all company departments to communicate a consistent message to targeted audiences without them realizing it. This is called an integrated marketing and communications (MarCom) plan. Developing an effective MarCom plan requires defining goals and markets, analyzing strengths/weaknesses and competitors, and determining marketing strategies and tactics. Key steps include situational analysis, SWOT analysis, competitor research, defining the target market and positioning, and outlining advertising, pricing, distribution channels, and the marketing budget and timeline.
