Ask HN: How to Report to Supervisors/CEOs

Hey! While I work fine and delegate well as a team leader and keep the team on track (and time), I still struggle to communicate achievements, relevant figures and more to my superior and the CEO. I can easily deliver those when asked but I think for the growth of the team and myself it's important to communicate those without being explictly asked. This still feels somewhat strange to me and it sometimes just gets lost in the daily business. Now I wonder how I can learn to communicate better. Maybe I should set a reminder bi-weekly for Friday afternoon to write a wrap-up of what happended in the two weeks. But maybe there are better ways to communicate or report to those above me in the hirarchy. Any tips, HN? Thanks!
