Challenge  During my last project, I was assigned the task to design a marketing campaign and decide  different marketing mediums for different segments of customers. The Manager asked us to  complete the work within 12 days with detailed market segmentation and campaigns for each  customer segment.     Selection  I used the visualization approach for segmentation and learning launch for designing the  marketing campaigns. I think the visualization of customer personas will help us in  connecting better with them and having empathy which will help us in better meeting their  needs. Also, we used the learning launch for marketing campaigns. Marketing is something  that requires experimentation and hence we used this tool.    Application  For the first task, we started collecting information about our customers. Segmentation based  on only age and demographics is not a good idea and hence we proceed through persona  making of customers    Visualisation helped us in this. We created a detailed persona that not only contains  information about age gender and other demographics but also contains information such as  likes and dislikes, preferences, problems they face and a short description. I am attaching a  template here for a better understanding. This persona helped us in visualizing our customers  better.     Then we began with designing the marketing campaign. We selected each segment and  everyone suggested different channels and mediums. We did test all the ideas using the data  from our previous marketing campaigns. The data helped us in accepting/rejecting the  hypothesis.     Insight and Approach  Visualization is an amazing tool. This helps in conveying our ideas better and in a more  concise manner. In our case, our team customer segmentation based on visualization helped a  lot. The segments are more accurate and easier to target. The product team also agreed to the  idea that persona helped them in understanding the customer better.    Learning Launch is also a great tool. Instead of rejecting our ideas on the basis of a  hypothesis, it's better to do some experimentation.  We tested our hypothesis by checking which marketing channels are more effective in  different segments
