Product Collaboration Best Practices
A condensed summary of the 25 most important product collaboration practices for Rust engineering teams - drawn from every page in this section.
-
Spec before sprint commit: Medium/large work needs tech spec with acceptance tests - Requirements to Technical Specs.
-
Non-goals in every spec: Prevent silent scope expansion mid-sprint.
-
Serde API sketch early: Types align PM and engineering before deep code.
-
Worker tier in specs: Tokio worker/async jobs documented with API, not afterthought.
-
Debt as risk language: Link to incidents and launch dates - Prioritizing Platform & Tech Debt.
-
15-25% platform capacity: Negotiated in roadmap, not hero Fridays.
-
Visible TECH-DEBT tags: Code links to backlog tickets.
-
Three-point estimates: Best/likely/worst with confidence - Estimation & Risk.
-
Spike before hard date: Unknowns get time-boxed experiments.
-
Re-estimate when learning: Update PM early, not demo surprise.
-
Include test and rollout in estimates: Merge is not done.
-
Quarterly engineering 1-pager: DORA, incidents, EOL cliffs to planning - Roadmap Contributions.
-
Outcome language on roadmap: Enable EU launch, not "async refactor."
-
Deprioritize with revisit trigger: Workspace split when team +4.
-
Impact-first updates: Customer % affected before stack traces - Stakeholder Communication.
-
Status / actions / next update UTC: Every incident and project message.
-
Options A/B for hard trades: PM decides with recommendation attached.
-
Exec summaries without jargon: Plain language post-incident.
-
Definition of Done includes staging deploy: Tests, logs, rollback noted - Making the Process Work.
-
WIP limits on review column: Flow beats story-point volume.
-
Retro one experiment: Measurable process change each cycle.
-
Trim SAFe to useful inputs: PI planning yes; vanity metrics no.
-
PM in design review for UX-driven APIs: Pagination and export limits early.
-
Say no with data: Risk register and alternative dates, not vague pushback.
-
Celebrate reliability wins: Share CFR improvement with product, not only engineering.
FAQs
How often meet PM 1:1?
Weekly 30 min for squad lead; async updates sufficient for stable streams.
Who owns the spec?
Engineer authors; PM signs acceptance; tech lead reviews feasibility.
Product in incident channel?
Comms lead or PM for customer messaging; engineers in technical thread.
Conflict over priority?
EM facilitates; data from roadmap and risk; tech lead owns technical veto on safety.
Remote product collaboration?
Written specs and recorded demos; decisions in ticket comments.
Sales custom requests?
Feasibility spike + maintenance cost in roadmap row before commit.
WASM product collaboration?
Size/perf budgets in spec acceptance; PM understands rollback to prior module version.
When escalate to exec?
SLA breach, launch miss with no options, repeated ignored EOL risk.
Collaboration metrics?
Spec cycle time, estimate accuracy trend, stakeholder NPS informal quarterly.
CLI shipped to users?
Include support burden and update channel in spec; PM owns release comms.
