I enjoyed reading this recent piece by Jared Spool - https://medium.com/@jmspool/developing-a-ux-practice-of-practicing-98976a2b6756 as it relates to improving soft skills to become better practitioners over time and towards this direction as an example - http://www.normative.com/to-innovate-re-imagine-yourself-first/ in what is the design of a mature practice and team in organisations.
What do you see as the critical soft skills and example activities/tasks in which these soft skills could be practiced?
Understand the answer may be role dependant and also soft skills may well cross over into many roles that make up a project team.
Be nice to gain a clearer understanding on fundamental soft skills as this is something I was not taught 20 + years ago, rather we jumped first into methods and had to discover the soft skills along the way. Also hard to find safe forums to practice and facilitators to help this along.
Welcome book recommendations as well.
