Ideas are easy/hard (delete depending on previous performance). Innovation is harder.
Why? Innovation starts with idea generation (well challenge identification if we're being accurate) and adds on selection and implementation. There are an ever increasing number of idea gathering offerings becoming available but for an organisation trying to embed innovation at the core of its operations these will not be sufficient.
Whatever an organisation's current innovation status an innovation process management system will be beneficial. The Jenni web application is one such system that all organisations who are serious about innovation must check out.
