Here’s what you’ll need and what you’ll make. You can return to this guide during any lesson.

Who this is for

Learners ages 14+ exploring work and adults preparing for an entry-level or next-stage responsibility. Work eligibility, supervision and occupational requirements remain separate.

Prepare before lesson one
  • Paper or a local document and a basic calculator are enough; all required records are supplied.
  • Recommended preparation: Practical Math and Data for Work and Training. Use fictional information throughout.
Your final project

Finish with proof you can use.

What to include

  • Build a constraint matrix before allocating routes; include the original-case decision evidence and a separate changed-case result.
  • Add J3 and return travel for full route end; include the original-case decision evidence and a separate changed-case result.
  • Save the paired assignment with all checks visible; include the original-case decision evidence and a separate changed-case result.
  • Recommend from comparable evidence and note the 10-minute assumption gap; include the original-case decision evidence and a separate changed-case result.
  • Draft a revised dispatch/customer update with the changed times; include the original-case decision evidence and a separate changed-case result.
  • Assemble dispatch packet and next verification action; include the original-case decision evidence and a separate changed-case result.

Review and revise

Use these criteria to check your work and choose what to improve.

  • The final packet uses the supplied task-specific constraints and all six records agree.
  • Every result can be traced to an identifier, input, calculation or stated decision rule.
  • Changed-case practice updates dependent records and keeps holds or uncertainty visible.
  • The packet states the learner role, authority boundary and specific next verification needed before real work.
Three ideas to help you along the way
Three useful ideas

The rules behind the steps.

01

Match the task-specific constraint

Dispatch assigns a worker and full time window to a specific job; skill, travel, access and break constraints are independent.

02

Keep decisions traceable

Preserve the original records and identify which person or policy can authorize a change; a plausible assumption is not approval.

03

Test the handoff

A dispatch handoff names which jobs are assigned, in progress, completed or held and must match the latest validated route version.

What do these words mean?
Key words

Key terms worth knowing.

Dispatch constraint
A required skill, time, access or resource condition on a job.
Door-to-door duration
Travel plus work and waiting through the return point.
Route propagation
Updating later times after an earlier change.
Feasible assignment
A job/worker plan meeting all stated mandatory conditions.

One useful project.

Work in order the first time. Each lesson makes something the next lesson can use.

  1. 1
    Up next

    Read each job and dispatch constraint

    Build a constraint matrix before allocating routes. Explain how dispatch assigns a worker and full time window to a specific job; skill, travel, access and break constraints are independent.

  2. 2
    13 min

    Compute door-to-door work windows

    Add J3 and return travel for full route end. Explain how a route accumulates travel, service time and waiting; using only on-site minutes understates the time commitment.

  3. 3
    11 min

    Match skills to the scheduled jobs

    Save the paired assignment with all checks visible. Explain how a feasible route can still be invalid if a skill-specific job is assigned to the wrong worker; the match must survive every reassignment.

  4. 4
    11 min

    Compare two feasible route assignments

    Recommend from comparable evidence and note the 10-minute assumption gap. Explain how comparing routes requires the same complete jobs and accounted travel; an apparently shorter plan that omits a job is not a fair comparison.

  5. 5
    13 min

    Replan after a delayed first job

    Draft a revised dispatch/customer update with the changed times. Explain how a delay can propagate through later appointments; recheck the full remaining window and communicate before promising completion.

  6. 6
    15 min

    Hand off a checked dispatch board

    Assemble dispatch packet and next verification action. Explain how a dispatch handoff names which jobs are assigned, in progress, completed or held and must match the latest validated route version.
