Example Reflection – Visualization

Challenge

I got a new role of data analysis and the role required handling, managing & analysing huge  amount of data. The data would be millions of excel line items. To analysis the data the  biggest challenge was to get all the small pieces of data in one place. Microsoft excel would  support more than a millions line items and getting the work done was a big head ace.

Selection & Application

Then I used was the tool of Visualization (Power BI). This tool helped me in getting all my  small pieces of data in one place. There was no restriction on the size and line items. I was  able to add all the files I wanted, amend it as per my requirement and start analysing the  data. I have used the technique of using a straw man visualization of a problem domain with  a set of questions or prompts for discussion to allow a diverse group of stakeholders to learn  from each other in the process of defining the scope, boundaries, key elements, and  relationships between elements to consider when identifying pain points and opportunities  for improvements or solutions. This helped me in been able to get my work done fast and  also get the desired outcome/results. Below is the application graph.

Insight & Approach:

The Visualization would of various shapes and sizes, the graphic is simple, using simple  shapes and icons available in the tool. If there was no desired outcome then then I would  create a different type of visual. Post the graphics, I would check whether the data is  correct, whether the Visualization is appropriate, whether the outcome is clearly visible,  whether the Visualization is helpful & appealing. By asking this questions I would feel  confident and would also be able to present my work nicely. Below is the insight graph :
