204363 - bug inflow and outflow

Status: RESOLVED FIXED

(Bugzilla :: Reporting/Charting, enhancement)

Description

[Marius Andreiana]

needed for forecasting a product release. 
Defect inflow is the rate at which new bugs are reported against the system
Defect outflow represents the number of bugs fixed each week

It is best to graph defect inflow and outflow on a weekly basis; daily graphing
has too much variability.

I'll attach a sample chart.

The bugs should also have a 'weight' depending on severity, for example:

blocker 30
critical  20
major 10
normal 7
trivial 3
enhancement 0

I'm pretty sure that gerv's stuff can be set up to do the graphing. Not the
weight thing, though. Taht woudl also cause issues - what if a bug is reported
as critical, then downgraded to normal and fixed the next week. You'd show a net
positive result, but thats not what really has happened.

Yes, bug 16009 can graph anything that can be queried - and you can certainly do
a query for all bugs filed in the last week etc. But it can't do the weighting
thing; you may just want to have a separate query for each weight and then have
a sum of them on the chart as well as the individual lines.

Mostly fixed by bug 16009.
