4. brainstorming
There is no such thing as a dumb idea. Encourage your team to come up with as many ideas as possibe. Write them down and build on top of them. Ask questions, there is no such thing as a stupid question. Everybody's opinion matters. The greatest inventions and companies were are created from BRAINSTORMING.
3. See the future
Always have a goal in front of view. Know what it is you want to get out of your new product. Make sure you do all you can to reach the goal, and after you have conqured that goal. Set a new one.
6. Work Comfortably
Let your team work in an environment that let's their creative juices flow the most. The company IDEO is a perfect example of this. There is no ordinary way of doing things inside this office. There is no dress code and their teams are full of all sorts of interesting and crazy ideas. Employees treat there office space as if it were there apartment; toys and all sort of goofy gadets can be found all over the office.
5. Prototyping
Another useful technique that marketing managers can use is prototyping. The key to prototyping is making mistakes. Mistakes lead to discoveries, and discoveries lead to adjustments and ultimately refinement. Prototyping isn’t about making a finished product as much as it is about getting ideas out in the open and refining them later. Prototypes are better than pictures and drawings because they give you a hands-on opportunity to fiddle with your products. Placement of certain features can be discussed and planned out as a result of prototyping as well.
