Frage zu

Maths - indexing

Could someone please help explain the maths reasoning and why the index (cost) is numerator and days are the denominator. Alternatively, any sources or concepts that may help improve my understanding on this analysis. 

I don't understand how cost/days means that the higher output (internal HR at 0.02) is more efficient than the lower output (external agencies 0.01). 

Thank you.

Hi there,

This case has 2.7 stars out of 5.

Basically, throw this case away - trying to make sense of a 2.7 star case could actually hurt your casing! There are quite a few things that don't make sense here…

I would suggest you to use other examples in the case library

Here I leave you the link of 4 cases that I have published here in the library. Another great thing is that, if you have any questions, you can reach out directly to the author!

A great thing about solving coaches´ cases, apart from them being very current, is that you can always reach out if you have questions or suggestions :)

Best regards,
