I usually share my experiences and point people towards the many articles about the importance of a strong product plan. After all, the product roadmap is a critical guiding document for many businesses. But that does not mean that a product roadmap is the only roadmap you’ll find in the workplace.

There are various categories and approaches to technology roadmapping  http://www.huffingtonpost.com/brian-de-haaff/the-value-of-a-technology_b_11805754.html
