Good day to you, Nkembo. Thanks for contacting CTB.
The most effective messages respond directly to customer needs and resources - to create new or strengthen existing solutions that they can apply to their own situations. So ,I recommend that you consider surveying (either formally or through focus groups, or informal conversations with) a reasonable sample of your customers. Ask general questions about what they do prefer, or do need, or do want you to add to your inventory; and listen patiently to their answers. Try to avoid asking questions that elicit "Yes or No" answers.
Take a look at several chapters within our Table of Contents (under the Learn a Skill graphic). I have checked below several competencies that may help you develop your information-gathering process.
