Ending poverty with software using globally distributed teams to tackle difficult problems presentation

  1. 1. Ending Poverty With Software Solving large problems with Open Source software, distributed teams, and Agile methodologies Adam Feuer, Van Mittal-Henkle, Adam Monsen Grameen Foundation Mifos Initiative
  2. 2. Poverty – a large problem <ul><ul><li>Six million children die of hunger every year, 17,000 every day. </li></ul></ul><ul><ul><li>2.7 billion people live on less than $2/day </li></ul></ul><ul><ul><li>(World Bank poverty definition; 2001 data). </li></ul></ul><ul><ul><li>40% of the total world population of 6.8 billion </li></ul></ul><ul><ul><li> </li></ul></ul><ul><ul><li> </li></ul></ul><ul><ul><li> </li></ul></ul>2.7 Billion Poor 4.1 Billion Non-poor

  7. 11. team/tools/code – late 2007 <ul><ul><li>team </li></ul></ul><ul><ul><ul><li>development in fits and spurts </li></ul></ul></ul><ul><ul><ul><li>no activity on IRC </li></ul></ul></ul><ul><ul><ul><li>unsearchable, unmirrored mailing lists </li></ul></ul></ul><ul><ul><li>tools </li></ul></ul><ul><ul><ul><li>clunky ci server, manual backups, haphazard system monitoring </li></ul></ul></ul><ul><ul><ul><li>subversion outages & performance issues ( svn) </li></ul></ul></ul><ul><ul><ul><li>parallel tracking/planning systems (Mingle + Issuezilla) </li></ul></ul></ul><ul><ul><li>code </li></ul></ul><ul><ul><ul><li>cumbersome, unmaintainable build w/Ant (unknown jar versions!) </li></ul></ul></ul><ul><ul><ul><li>didn't know what version of our code our largest customer is using </li></ul></ul></ul><ul><ul><ul><li>monolithic codebase </li></ul></ul></ul><ul><ul><ul><li>Mifos only ran in JBoss and was only usable from Internet Explorer </li></ul></ul></ul><ul><ul><ul><li>insanely slow & cumbersome compile/edit/fix cycle </li></ul></ul></ul>
  8. 12. team/tools/code – Today! <ul><ul><li>team </li></ul></ul><ul><ul><ul><li>scrum with daily standups, iterations, burndown </li></ul></ul></ul><ul><ul><ul><li>this slideshow is a remix of one given by a volunteer </li></ul></ul></ul><ul><ul><ul><li>awesome IRC channel </li></ul></ul></ul><ul><ul><ul><li>searchable, multi-mirrored mailing lists </li></ul></ul></ul><ul><ul><li>tools </li></ul></ul><ul><ul><ul><li>Hudson CI server, tested backups, awesome monitoring via OpenNMS </li></ul></ul></ul><ul><ul><ul><li>distributed version control ( git) </li></ul></ul></ul><ul><ul><ul><li>single, powerful issue tracker and planner (JIRA Studio) </li></ul></ul></ul><ul><ul><li>code </li></ul></ul><ul><ul><ul><li>predictable, modular build w/Maven (proper dependency management!) </li></ul></ul></ul><ul><ul><ul><li>codebase divided into modules, API and plugins </li></ul></ul></ul><ul><ul><ul><li>Mifos runs in any servlet container and is usable from any browser </li></ul></ul></ul><ul><ul><ul><li>much improved compile/edit/fix cycle (Eclipse WTP) </li></ul></ul></ul><ul><ul><ul><li>customers running known, tested versions of our code </li></ul></ul></ul>
  9. 13. Distributed, Agile, Awesome <ul><ul><li>documentation on (crowdsourced barnraisicalized synergy!) </li></ul></ul><ul><ul><ul><li> </li></ul></ul></ul><ul><ul><li>distributed decision-making </li></ul></ul><ul><ul><ul><li> </li></ul></ul></ul>

  13. 17. Mifos Technology Roadmap (Target)
  14. 18. Get Involved! <ul><ul><li>Join the global collaborative Mifos community and united effort to build and extend this platform that fuels innovation from the bottom up and empowers the poor to ascend out of poverty. There are many ways to get involved: </li></ul></ul><ul><ul><ul><li>Build acceptance tests </li></ul></ul></ul><ul><ul><ul><li>Find & fix bugs (look around JIRA for open issues you could have a go at) </li></ul></ul></ul><ul><ul><ul><li>Answer questions on mailing lists, participate on IRC </li></ul></ul></ul><ul><ul><ul><li>Guide implementations on-site </li></ul></ul></ul><ul><ul><ul><li>Write new or complete existing documentation </li></ul></ul></ul><ul><ul><ul><li>Translate Mifos UI or documentation </li></ul></ul></ul><ul><ul><ul><li>Localize by building local region-specific reports </li></ul></ul></ul><ul><ul><li>Get on the mailing and/or IRC and say Hello! People will point you to how and where you can contribute. </li></ul></ul>
