What are the internal and external factors that impact on marketing activities?

Successful marketing relies on both internal and external factors. Internal factors include the fact that marketing plans must have support and organization to see it completed successfully. An unconvinced management team will not ensure it has the resources of manpower it needs. External factors, focus more on making sure market research has been done. If marketing activities are pushed toward the wrong consumers, the plan will fail. Additionally, a finicky consumer base is hard to target with marketing.
