I'm an E5 iOS at a Big Tech company reporting to an M2. I'm leading the mobile side for a multi-quarter product project that leverages work from 2 platform teams. Most of the complexity of this project will be on the mobile side. My backend lead is an E6 full-stack web engineer reporting to an M1 who reports to my M2. The M1 is on parental leave until late Dec / early Jan. This E6 has been an amazing partner and teammate.
The 2 platform teams have missed a lot of their timelines. One dependency is about a month behind schedule. They often give us deliverables that are dev-complete and not tested (e.g., compilation errors, etc.). We have sync meetings 2x/week, but 1 platform team has never attended any of these meetings. The other platform team doesn't always send the same engineers to the meeting and doesn't always know the status of their own deliverables. That platform team's EM got terminated for performance reasons before this project started, so their M2 and a TPM have been tag-teaming to fill in the gap. That means sometimes their M2 attends the sync meetings, sometimes the TPM attends, sometimes both attend, and sometimes neither attends. The TPM sends a weather report on that team's deliverables every other week, but hasn't sent one in the past month. In his last email, he listed my E6 and me as the DRIs for their team's deliverables. When I confronted him about it, he said it was a mistake and he'll fix it in future emails. How do I bring visibility into these delays to external stakeholders?
I created a shared Google Doc to track all the dependencies, including when our team needs the deliverables, the other team's ETAs, and any notes. However, it's been challenging getting ETAs from the other teams. When I tagged them in the Google doc asking for ETAs, they just ignore me.
My manager gave me feedback to "influence engineers to hold up their timeline than push for hard commitments". Do you have any concrete advice here? I'm not sure how to do this.
After I escalated the 1st platform team's unresponsiveness to their Director (3 levels up), the E6 iOS DRI became very responsive. Escalating to that E6's skip level had not been effective. Should I just keep escalating everything or is there a better approach?
