Calculating Schedule Variance and Defect Density on a Waterfall project

[Sajit Nair _Trundl_]

Hi beautiful members,

A client is using a Kannan project in jira to manage their waterfall projects.

They want to calculate Defect density and schedule variance for those projects.

Epics are being used as milestones and tasks, bugs etc are connected to epic to show up as milestone level reporting in gadgets.

I found this formula online..

Defect Density = Defect count/size of the release

so the defect density "per milestone" would be total count of defects (I think I can just add up total bugs linked to milestone) / size of milestone (milestone size will be sum of all tasks associated with it.) 
Do you think my approach makes sense ?

and for schedule variance, I found this formula online - 

(actual duration - planned duration) / planned duration * 100

Any suggestions would be helpful?

Hi @Sajit Nair _Trundl_ 

As your client is specifically asking for those measures, I suggest asking them how they define those measures.  That will help you align to their expectations before trying to measure those things.

Best regards,
Bill
