Conduct a credible systems investigation

Construct falsifiable systems claims, controlled comparisons, causal performance explanations, and reproducible artifacts that survive competing interpretations.

  1. 01

    Systems claims and falsifiable hypotheses

    Turn a promising observation into a scoped hypothesis with measurable outcomes, a practical threshold, and a result that could contradict it.

    30 min
  2. 02

    Workload representativeness and trace provenance

    Connect a performance claim to its target workload through explicit sampling, trace transformations, and population weights.

    30 min
  3. 03

    Baseline equivalence and tuning fairness

    Compare complete systems under equivalent correctness and resource contracts while accounting for search effort and tuning selection.

    30 min
  4. 04

    Factor isolation and ablation design

    Use controlled factor combinations to distinguish main effects, interactions, and the narrower conditional meaning of an ablation.

    30 min
  5. 05

    Repeated runs and variance decomposition

    Allocate repetition to independent experimental levels instead of treating every nested timing as a new system execution.

    30 min
  6. 06

    Performance counterfactuals and mechanism tests

    Test why an improvement occurs with explicit interventions, predicted mediators, and alternatives to a favorable profile.

    30 min
  7. 07

    Simulation calibration and external validity

    Separate implementation verification, fitting parameters, held-out validation, and transfer beyond a simulator’s tested application domain.

    30 min
  8. 08

    Negative results and failure-envelope mapping

    Turn regressions, timeouts, and unsupported conditions into a precise map of where a mechanism succeeds or fails.

    30 min
  9. 09

    Artifact packaging and independent reproduction

    Package the complete evidence path from immutable inputs to claim-linked results, and report exactly what independent execution established.

    30 min
  10. 10

    Research claim scope and limitation writing

    Write conclusions that preserve the measured domain, uncertainty, comparison contract, and unresolved alternatives.
