Workshops are for those who want to find the greater treasures that lye in the people, the products or service they have. What you have is already a good thing or the business wouldn't exist. Getting better is the life blood of the business, without it competition overgrows it.
Qualified training staff deliver training in innovation to seek out the visions of the future and to guide the creation and connect them with the plan to deliver it.
Plans need to be formed to capture a vision and hold it.
If you see that this is what your business would benefit from, to re inspire your developers then please contact Andrew.
