One of the difficult things about being a product specialist is the focus on metrics; yes, taking tickets (calls/emails/chats) is the main part of the job, but I feel the most growth I have gotten in this role are from activities that do not earn me tickets. As a team lead, I am gaining management skills, interfacing with other departments about the product, and spreading knowledge, but I am not compensated for these extra responsibilities in the form of tickets. In the projects that I take on, I find myself adding value to the company that also does not show in my metrics. Ultimately, I have made my peace about not rushing through the role to the promotion or being the top performer; since the role is so flexible to allow you to gain the skills that you want out of it you will need to pick and choose what measures of success you decide to use to assess your own performance.
