Ready to assign people across available capacity.

What this tool does

A random assignment generator maps entries from one list to targets in another, respecting configured capacity and repeat rules rather than merely shuffling a single list.

Two-list assignment

Ways to assign one list to another

Assign people to routine tasks

Map an eligible list to low-stakes duties when the tasks do not require skill, legal, or safety qualifications.

Distribute topics or materials

Assign students or participants to prepared topics, objects, or stations with visible target capacities.

Allocate entries across repeated slots

Use one-to-many mode when each target can receive several sources and the allowed capacity is known.

Instructions

How to configure an assignment

Add the source list

Enter each person or item that should receive exactly one assignment in the current run.

Add the target list

Enter tasks, roles, topics, or destinations and give each target a capacity when more than one assignment is allowed.

Choose repeat and capacity rules

Specify whether targets may repeat and verify that the total capacity can accommodate the source list.

Generate and inspect the table

Review assignments and unmatched entries, then copy or export only after confirming the input lists were eligible.

Troubleshooting

Capacity and list problems

Total target capacity is too small

When: The source list contains more entries than all target capacities combined.

Why: At least one source must remain unmatched under the selected rules.

Try: Increase capacity, add targets, reduce the source list, or accept a clearly reported unmatched set.

One of the lists is empty

When: No usable source or target entries remain after cleanup.

Why: An assignment requires at least one entry on both sides.

Try: Add and review both lists before generating assignments.

Duplicate target labels are ambiguous

When: Two targets normalize to the same visible label.

Why: The result cannot clearly show which capacity or destination was intended.

Try: Give each target a distinct label and rerun the assignment.

Assignment rules and private inputs

Random assignment starts after eligibility is decided

The tool can apply capacities and repeat rules but cannot determine who is qualified, willing, or safe for a target.

  • Equal eligible sources receive random placement under the same configured rules.
  • Different target capacities intentionally make some targets appear more often than others.
  • The operator must resolve skills, accommodations, conflicts, consent, and workload before using the result.

Both lists are not saved

Source entries, targets, capacities, settings, and results are used to complete the active task and are not saved by Random 42.

  • Random 42 does not save recurring duties, people, targets, or results between sessions.
  • A copied or downloaded export leaves the tool only through an action you initiate.

Boundaries

What random assignment cannot judge

Do not assign work that requires qualification checks

This generic tool is for simple allocations after eligibility and capacity have already been established.

Review before you use the result

  • Do not use it for medical duties, regulated work, employment decisions, safety roles, or disciplinary tasks.
  • The tool does not balance workload history, preference, skill, availability, or legal rest requirements.
  • Use a specialized workflow when assignments require a domain-specific rule model.

FAQ

Frequently asked questions

What is the difference between one-to-one and one-to-many?

One-to-one uses each target once, while one-to-many allows a target to receive several sources up to its configured capacity.

What happens when capacity is too small?

The tool reports unmatched entries rather than silently dropping them. Increase capacity or change the input before accepting the result.

Can the same target be assigned repeatedly?

Yes when its capacity and repeat rule allow it. The result always follows the configured limit.

Are the two lists uploaded?

No. Sources, targets, rules, and results are used for the active task and are not saved by Random 42.
