I can help you evaluate a technology, ponder the risk of its adoption, see how easy-to-use it is, check its level of support, appraise how steep the learning curve is, study the feasibility of its integration, and investigate common problems related to it.
My additional point of view will make you more confident when deciding to adopt a technology.
