We used our Idea Management software platform - HunchBuzz for the Idea generation and collaboration part of the process. I suppose similar to how OpenIdeo is operating.
Initially I collaborated with the Change & Transformation Manager at the Council and over a period of weeks created and refined a 5 step process for Idea to Implementation. This was supported by the platform and facilitated by the Transformation team and endorsed by the CEO.
The real power came about from the employees who had never truly had an opportunity to express Ideas previously. The more the Ideas came the more people became engaged...because they became more engaged they performed better and the quality of a lot of employees work improved and also created a ripple effect throughout different departments as they started to perceive what was a possible in an entirely new way.
Basically a chain reaction occurred, which has spread not just from the Council but also to other areas of the City(Universities, Business etc). I am currently putting together a Case study so if you like I can send you a copy?
