I often am asked about the most important elements to building a strong roadmap. 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.
A technology roadmap (also known as an IT roadmap) is a document which outlines the plan to reach short-term and long-term goals through the use of technology solutions. This type of roadmap typically provides key information which helps organizations make better decisions around technology investments.
The central planning consideration is to ensure that technology and infrastructure investments will meet the short-term and long-term goals of the organization.
There are various categories and approaches to technology roadmapping http://www.huffingtonpost.com/brian-de-haaff/the-value-of-a-technology_b_11805754.html
