Service Jam newbie’s experiences in the Global Service Jam Helsinki 2016

On Friday evening approximately 7 pm about 50 participants of the Global Service Jam Helsinki 2016 sitting in the auditorium in Laurea Leppävaara heard a sound of a water splashing. That was the secret theme of this year’s Jam.

Then the jammers chose seven most interesting problems, everyone picked the problem that interested them the most and the teams started to build around the problems.

Our team had lots and lots of ideas and the conversations were really active the whole Friday evening. We collected all our ideas and the concept called “coolWater” formed quite fast. coolWater concept consists of an intelligent, reusable water bottle, a mobile app and coolWater refill stations, where the user can fill up their water bottles.  You can read more about the concept here .


On Saturday morning we made our first very rough prototype of our idea and then headed to Sello shopping mall where we made a short survey by asking people if they carry water bottles with them and what they thought of our idea of coolWater concept. After the research we came back and continued building the prototype and describing the customer journey by making videos where we showed the actual user situations of the concept. We also described four different user personas and made a business model canvas of our concept.

Sunday morning went fast while finishing the prototype, user situation videos and the presentation. Our presentation was a video consisting of the backgrounds of our concept, user situation videos and drawings of the prototype. We finished our presentation video only few minutes before the deadline on 2 pm.
