Promotion Q&A and Videos

I recently started a side project that could have an org level impact soon within this year. The feedback for the prototype is pretty good and I got a green-light to put more bandwidth in it.

I used to think once I get the good work done, promotion should come naturally. But both my manager and skip manager are telling me to leave proper documentation and communication as evidence for promotion - docs like PRD, roadmap planning, status update etc.

I usually do communications pretty well, so their feedback make me wonder if I missing something for a staff level promotion.

• What kind of evidence is being valued in a staff promo packet? Any differences between senior and staff promo packet?
• What do I need to highlight and keep track of if I'm creating scope outside of daily work?
• What kind of data I should keep track of to quantify the impact? How do you usually learn about finding the matrix to track?

Thanks!

As you climb up the career ladder (senior -> staff), this soft skill becomes more and more important. What are some ways I can keep honing it? Are there any professional courses I can consider?

I would learn to be effective and efficient at it, specially in scenarios such as public speaking, team meetings, project status, emails etc.

Also, English is not my first language.
