Lessons Learned


What problem we focus to?


•Many of failed projects tackled to wrong problem.



•Many of failed projects tackled to wrong problem.

•Starting from a suitable sized problem is important.



•deploy quickly, get feedback.

•Needs of disaster area is always changing.

•Late output will miss the opportunity.

Speed and output


•Sometime crowdsourcing generate great value.

•But many projects need constantly resources from NPO, government, companies.

•Open collaboration will help to make your projects sustainable.

Open collaboration
