Story telling with Excel Power BI

{6 Comments}

With Power Business Intelligence (BI) tools of Excel 2013, one can metamorphose raw data and/or results of complex calculations into stunning and interactive visualizations.  Power View (one of the four components of Power BI) allows one to create a PPT like flow in Excel thus allowing one to weave a story.  To be able to interact with/create visualizations, you will need to install Microsoft Office Professional Plus 2013 (this version will already have two of the four components of Power BI - PowerPivot and Power View).  Additionally, you will have to install the following add-ins from Microsoft (the other two components of Power BI)

1. Power Query; and
2. Power Map

I have tried to showcase the prowess of Power BI tools of Excel 2013 in these two workbooks:

1. An overview of the BRIC Economies
2. Sales data analysis

Given the following inputs/restrictions, one may want to compute the end date and time of a project:

1. Start date and time of the project; and
2. Official working hours; and

Furthermore, to add to the complication, one may have different National holidays and weekend days i.e. while for some, the weekend days may be Saturday and Sunday, for others it may be Friday and Saturday.

You may refer to both my solutions here

1. Given National holidays and where Saturday and Sunday are the weekend days - Download workbook.  This solution will work in all Excel versions

2. Given National holidays and where Friday and Saturday are the weekend days - Download workbook.  This solution will work only in Excel 2010 and higher versions.
