What is the biggest problem when we want to be innovative

Lets say You want to make an educational system for young children with some sort of learning disabilities. You have domain expert in this area, you specify requirements, design and develop the system. A really good system. Everything is fine but…

Some teachers and therapists (usually in middle age) used to use a sheet of paper and pencil or a black or white board. They don’t feel comfortable using computer specially for education.

They feel comfortable with paper, pencil etc. You have just computerize some niche but users in this niche aren’t convinced that specialized software can help them…

You may be right that using computer can really help them but it will take some time you make some money…

Your problem is you had forgotten ask potential users if they think this kind of software could help them…

On the other hand they can feel that this software make their job, so they are useless… So this software takes away their job instead of helping them…

So the biggest problem can be people’s habits and beliefs and fear of being useless.
