### Reflection - Visualization ###

#Challenge#  I work as a data analyst in a company. My job is, mainly, to find insight from data.

One of my previous task was to distinguish who might be an online merchant from our existing  customers.

Due to my company policy, I cannot walk through details of how I did the job.

But I would explain roughly that it required considering several factors and complex calculation in the  process.

Eventually, I needed to present the methodology used in this job in one of the conference my company  holds.

To explain the methodology to management team or person who has no experience in this field seemed  to be challenging.

That was how of my challenge came from.

#Selection#  It was virtually impossible for me to explain everything by words.

As described in the 'Visualization Tool' lecture video, things might be different if we try to explain them  using a visualization.

To make the presentation simpler, I thought that some kinds of images or illustration might do the job.

Therefore, I decided to illustrate the methodology by creating a visualization in my presentation.

#Application#  After I decided to use an illustration to explain the methodology, I tried to imagine what kind of image  would help me.

I needed to explain how people interact when they are having online purchasing.

I tried several ideas but the idea that seemed to be the best one was putting a map of my country and  adding man / woman icons to illustrate online purchasing activities.

I tested it with my colleagues and the result was satisfactory. Then I used it in my presentation and  everything went smoothly in the presentation. The audiences paid attention and asked a lot of  questions because they were interested in my presentation.

#Insight & Approach#  I learned a lot from this task because it taught me how should I prepare the slide and how should I  conduct the presentation.

I also learned that using a tool like this can help a lot in my work.

I think I might have a chance to use other design thinking's tool in other situation.

Back at the time I did this task, I also considered using the story telling tool as an alternative tool.

Story telling might help with the task as well. But due to lacking of a good story or a strong example to  tell, I could not apply it to the task.

I ended up using only visualization tool. Nevertheless, the result was already good.
