Final answer:
Marketing planning should include all of the following except ratio analysis.
Step-by-step explanation:
In marketing planning, all of the following should be included except ratio analysis. Marketing planning involves setting SMART goals, which are specific, measurable, achievable, relevant, and time-bound. It also includes creating sales forecasts to predict future demand and developing a marketing budget to allocate resources. However, ratio analysis, which involves analyzing financial ratios to assess a company's performance, is not typically part of marketing planning.
