Scrum iteration planning plugin


This plugin provides some basic project management essentials to do Scrum-style iteration planning in an Agile project.

The plugin is a sort of Trac adaptation of the concepts in Agile Estimating and Planning by Mike Cohn

The code itself is a radical merge&rework of TimingAndEstimationPlugin and ScrumBurndownPlugin. The billing features in TimingAndEstimationPlugin have not been implemented, and the JavaScript charting features in ScrumBurndownPlugin have been redone with a Java applet using JFreeCharts. Also, the burndown chart has been changed into a burnup, and the the milestone period is indicated by an interval marker.

The upgrade procedure creates a column called 'started' in the milestone table, some SQL views and functions, and some Trac reports. No external scripts are needed to collect iteration statistics. Everything is done with SQL queries.

The plugin needs two custom ticket fields, so the following must be added to the trac.ini file of the environment:

estimatedwork = text
estimatedwork.label = Estimated Work
estimatedwork.order = 1
estimatedwork.value = 0
workdone = text
workdone.label = Work done
workdone.order = 2
workdone.value = 0

I did most of the development on Windows/Apache/Postgres 8.1.4. I really have no idea if the SQL will work on any other backend, and I doubt I'll ever find the time to test with other setups.

I didn't find any way to make the Python setup utilities also build the Java applet, so I had to use a trivial Makefile. As long as Python and javac are in your path, it should work. I did try to run Cygwin GNU make 3.80 on it, and it seems the Java target build statements upset the shell. Couldn't figure out why :-(

I did all the development against Trac 0.11 and then backported to 0.10. The backport changes are actually quite trivial. In fact I left the 0.11 code commented out and ready to kick in. I just didn't feel like creating and maintaining two different branches.

You can check out ScrumPlugin from here using Subversion, or browse the source with Trac.


Instead of entering some value that is then added to the workdone counter for a specific ticket, users enter the actual new value. So if for a ticket the current number of workdone hours (or whichever tracking unit you chose for your project) is 7, and an engineer has just done 3 more hours, he should simply input 10 and submit.

The iteration burnup chart simply groups all the tickets that currently belong to the selected milestone, and starts plotting all changes to the the sums of their work estimated and done values. The iteration period is marked by an interval marker. If work has done on the tickets outside of the iteration period, then some points will be plotted outside the marked area.
