A Reproducible Football Scouting Shortlist Workflow

A shortlist is useful only if another person can explain why every name entered it. A ranking copied from a chart is not yet a scouting process: it may hide the role, period, eligible leagues, minutes rule and metrics that produced the order.

A reproducible workflow preserves those decisions from the first question to the final handoff.

1. Write the Recruitment Question

Begin with the squad need, not a player name.

Identify midfielders in the selected competitions who can support progression and chance creation, meet the age and exposure criteria, and merit video or live review.

This is a screening question. It does not claim that public event data can decide recruitment.

2. Translate the Role

List the responsibilities that matter in the intended team context. Separate:

• essential responsibilities;
• useful secondary traits;
• constraints such as age, competition or availability;
• qualities that require video, physical, medical or character assessment.

The role-based metric guide helps translate responsibilities into evidence without treating popular metrics as universal.

3. Freeze the Eligibility Rules

Before inspecting results, record:

• period and cutoff;
• competitions;
• position group;
• age range if relevant;
• minimum minutes or matches;
• absolute or per-90 mode;
• exclusions.

Use the fair comparison contract to keep these rules consistent.

4. Use a Population View First

A scatter or swarm is useful for screening because it keeps the eligible population visible.

A scatter can show whether two role-relevant measures move together, reveal trade-offs and help identify unusual combinations. A swarm can show where a player sits in one or more distributions and whether an apparent rank represents a real gap or a dense cluster.

Do not label only famous players. Highlight the subjects selected by the stated rules and keep the rest of the population visible as context.

5. Create a Longlist Before a Shortlist

Treat the first visual selection as a longlist. For each candidate, record the reason for inclusion:

This prevents a chart highlight from becoming an unsupported recommendation.

6. Run Sensitivity Checks

Repeat the view after one reasonable change at a time:

• higher minutes threshold;
• separate competitions;
• narrower position group;
• totals instead of rates;
• one metric removed from a composite axis.

Names that disappear under every reasonable alternative may have depended on a fragile setup. Names that remain are not automatically better, but the screening signal is more robust.

The cross-league comparison guide is especially important before combining competitions.

7. Build Candidate Profiles

Once the population view has produced a longlist, use a radar or player bar to inspect individual metric profiles. Keep the same period, population and unit so the profile remains connected to the screening step.

Do not expand the metric set merely because the profile has space. Every axis should answer a role question.

8. Preserve the Decision Trail

For every edition of the shortlist, store:

• recruitment question;
• filter and metric configuration;
• chart type and unit;
• date and data cutoff;
• highlighted players;
• sensitivity checks;
• changes from the previous edition;
• named human reviewer.

The reproducibility manifest provides the minimum record, while the report-ready chart guide covers the final handoff.

Build the First Longlist

Open the relevant FBPlot population creator, apply the frozen rules and highlight only candidates whose inclusion reason you can state in one sentence. Export the population view and its configuration together. The purpose is not to automate scouting judgement; it is to make the first screening step visible and reviewable.
