Background - Worked in IT/Systems Management for 10 years and eventually moved on to consulting on sites and webapps. Started as UI/UX Dev role at IDX and quickly moved into the Product Manager role. Communication is the biggest part of the job, with linking up projects and managing resources/timelines also taking up a lot of time. You're generally going to be the glue between Marketing/Sales/Support/Business so being knowledgable AND approachable are must have skills. The product is your baby and so you have a huge amount of responsibility on your shoulders. Vision and execution are on you.
