name: sigmod-workflow description: Use when planning a SIGMOD project calendar under the PACMMOD round system, covering round selection and hopping, backward planning from abstract and paper cutoffs, the feedback and revision windows, embargo-aware contingencies, and coordinating a systems-building team against quarterly deadlines.

SIGMOD Workflow

SIGMOD project management differs from single-deadline conferences in kind: with four research rounds a year feeding PACMMOD issues, the strategic variable is which round, and the punishment structure (a 12-month embargo on rejection, one month to execute a revision) rewards teams that plan the whole round, not just the deadline. Anchor every date below to the live important-dates page before acting; the quarterly pattern is durable, the dates are not.

The round as a five-act unit

Act 1  Abstract + COIs        (deadline minus ~1 week)
Act 2  Paper deadline         (the 17th of the round month, AoE, for 2027)
Act 3  Feedback phase         (~2 months in; one-week reply window)
Act 4  First verdict          (~3 months in: accept / reject / revision)
Act 5  Revision + final       (+1 month to resubmit, ~+3 weeks to decide)

Block engineer time for Acts 3 and 5 when you submit, not when they arrive: the feedback week may need a fast counter-experiment, and the revision month is a sprint that assumes the original evaluation was scripted end to end (see sigmod-reproducibility).

Round selection under the embargo

Situation	Recommended move
Evaluation complete, writing mature	Nearest round
Core result solid, one comparison missing	Next round; a missing baseline reads as reject, not revision
System working, evaluation thin	Skip two; thin evaluations burn the embargo
Racing a known competing group	Weigh nearest round against reject risk; PVLDB's monthly gate may beat waiting
Paper rejected last round	Different venue — the track is closed for ~3 rounds

The asymmetry to internalize: submitting early costs a possible year; waiting costs three months. Under uncertainty, waiting is usually the cheaper mistake at this venue.

Backward plan from a paper cutoff

• T-16 weeks: freeze the system's architecture; feature work after this point invalidates measurements.
• T-10: evaluation matrix locked (workloads × baselines × sweeps); harness and seeds committed.
• T-6: full experiment pass complete once; draft carries real numbers, not placeholders.
• T-4: internal adversarial read by a colleague who builds systems; schedule their week now.
• T-2: rerun-from-scratch of every figure; repro ledger shows zero DEBT.
• T-1 week + a few days: abstract, authors, topics, COIs into CMT.
• T-0: PDF up; verify the uploaded file, not the local one.

Team coordination specifics

• Name one owner for the measurement harness and a different owner for the anonymity sweep; both jobs fail under shared custody.
• Keep a submissions ledger across the group: PACMMOD's exclusivity rule and the 10-papers-per-author annual cap are portfolio constraints, not per-paper ones.
• Archive the exact submitted PDF, the CMT confirmation, and the frozen artifact snapshot; the revision letter must quote and diff against them.
• Pre-agree the reject plan (PVLDB? ICDE? rework?) while everyone is calm; deciding it the day the verdict lands produces venue-shopping errors.

Interleaving multiple projects

Quarterly rounds let a group pipeline: project A in Round 1, its revision landing while project B targets Round 3. The trap is revision collision — two revisions in the same month exceed most teams' experiment bandwidth. When two papers are near-ready, split them across non-adjacent rounds deliberately rather than shipping both into one.

Small-team and solo variants

The five-act structure assumes bench depth; without it, adjust:

• A solo author cannot staff a feedback week and a revision month on top of other obligations — prefer the round after the one that looks feasible, and treat the slack as the plan, not padding.
• Compress the evaluation matrix before compressing run hygiene; fewer workloads with clean provenance beat a wide matrix that cannot be regenerated during a revision.
• Recruit the adversarial reader early even when solo — the T-4 external read is the step small teams skip and most regret at verdict time.
• Consider whether PVLDB's monthly gate suits a solo pipeline better; a missed monthly deadline costs weeks, a failed SIGMOD round costs a year.

Conference layer

Publication and presentation decouple: your issue ships on the round's schedule, and the talk happens at the next conference edition (SIGMOD 2027: June 13–19, 2027, Huntington Beach; SIGMOD 2026 was May 31–June 5, Bengaluru). Budget registration and travel when the acceptance lands, and schedule the ARI artifact push (sigmod-artifact-evaluation) into the gap between issue and conference.

Calendar-keeping discipline

Because every date in this skill perishes, institutionalize the refresh: at the start of each quarter, one team member re-opens the current important-dates page, diffs it against the team's planning calendar, and posts the delta. Rounds have shifted between cycles before; a plan anchored to a stale calendar fails silently until the abstract deadline passes. The same quarterly sweep should touch the ARI edition page and, for groups with industrial collaborations, the industrial-track CFP status.

Output format

[Target round] round + year, with selection rationale
[Stage now] pre-abstract / submitted / feedback / verdict / revision
[Backward plan] next three milestones with owners
[Bandwidth check] feedback + revision windows staffed yes/no
[Portfolio constraints] cap headroom, exclusivity conflicts, collisions
[Reject plan] pre-agreed next venue
