Improving Design Readiness Before Engineering Handoff
I brought engineering into design refinement earlier and created a shared place for comments and small bugs, so open details were easier to work through together. Reviews of a PS App session-summary feature show how a thoughtful pause for another iteration helped resolve experience and data questions before handoff.

A gap between design completion and build readiness
One source of friction between design and engineering was their different understanding of when work was ready. Designers could consider a feature complete, then engineering would uncover blockers during technical investigation. The issue was not simply whether screens had been finished. Important questions were being discovered after the design team believed the handoff had happened.
I worked on the timing of collaboration around that transition. More detailed handoff files would still leave feasibility questions too late if engineering first examined them after design considered the work complete. I invited engineering into refinement earlier and kept the design roadmap communicated to engineering, creating overlap while decisions were still flexible.
The intent was a smoother transition and greater confidence about what would change once development began. I did not measure a reduction in rework or delivery time, so those are not results I attribute to the process.
Reviewing the feature beyond its individual screens
The session-summary work brought the same readiness question into a concrete design review. A designer on my team proposed surfacing a player’s last session through three changes: moving the content higher on the page, giving recently played a new visual and animation treatment, and adding an entry point for captures.
The proposal supported the program’s engagement and customer-satisfaction goals. My role was to review the experience and help the designer balance the intended direction with what the available data and surrounding app structure could support.
I asked for the play-deck variant to remain in the mocks. Keeping that context visible allowed the work to be considered as part of the page, rather than only as a compelling isolated component. It also made it easier to discuss how the new session treatment related to existing recently played content.
Identifying unresolved choices before handoff
Several details needed more attention. I flagged three entry points to Trophies as too many. I also questioned the fallback logic for game logos: should the displayed identity reflect the last session or the current one?
These were small interface details with broader implications. Multiple routes to the same destination affected the hierarchy of the page. A fallback rule affected whether the session content remained understandable when the expected data was unavailable or different from the player’s current context.
I approved the designer’s entry-point animation while holding the feature for another round before engineering handoff. That allowed the review to distinguish between an element that was working and questions the team still needed to resolve. The visual direction could progress without treating the entire experience as ready to build.
I also deferred the next review by a couple of weeks so the team could focus. The work needed space to reconcile its goals with feasibility, rather than an immediate succession of reviews without enough time to revise.
Keeping follow-up work visible
The handoff process also needed a way to handle the small issues that remained around delivery. Design comments and bugs had been scattered across design files and issue tracking. I built a tracking system that gave design and engineering one place to work from.
The system distinguished acceptable minor bugs from critical issues that needed escalation. Designers could see the relevant work in a shared dashboard view instead of searching across separate conversations and files.
This supported a more continuous working relationship around delivery: earlier refinement for consequential questions, a review before handoff, and a visible place for the details that needed follow-up. It did not remove the need for judgment about which issues mattered most.
What the work changed
I established earlier engineering involvement in refinement and a shared tracking space for design comments and small bugs. In the session-summary review, I made the decision to continue iterating before handoff, while preserving the parts of the direction that were working.
The feature’s product results were still pending. The case demonstrates my contribution to readiness and design judgment: examining the experience in context, identifying unresolved logic, and coordinating the work around the transition into engineering.
