From turn-key to disruptive
You have probably already tried a few times to get your team to think out-of-the-box. Some new ideas came up, but died after a few months. Your problem is that you don't have a proper pipeline for new ideas, you lack enablers in your team and overall you higher management likes new ideas but don't feel wasting time and money.
Quite likely the bigger problem is the lack of a process and the implementation of the process in the entire company. If you don't get the commitment from all stakeholders and particularly decision-makers, even the best ideas will fail. Or, if you only get juniors for a brainstorm, having limited market, business and user knowledge then you will get very creative fresh ideas but they will loose their value quickly during validation or at implementation.
Our service focuses on helping our clients improving (parts of) the innovation process by considering every step during your innovation cycle and guide you along the way where improvements are required. Note that in practice this process is never this clean: often enough during prototyping and validation new insights appear and problems get redefined.
With experience from working at design agencies and innovation labs and helping clients and start-ups worldwide we know how difficult it is to build a successful lasting innovation culture. Innovation is doing something inherently new and this means learning new things which goes with a lot of trial-and-error. Companies more dedicated to innovation however have proven to be more successful than those who don't innovate but only go for short-term success.
