Write a brief that another person could operate
Plan a fictional one-day student conference with a 250-person venue limit. Tickets cost $40, variable catering and materials cost $18 per paid participant, and fixed costs are $2,500 venue, $900 audiovisual and $400 promotion. A sponsor has confirmed $1,500 under the exercise’s assumptions. No tax, payment-processing fee or additional revenue is included.
BLS describes event-planning work as coordinating locations, transportation and other details, communicating with clients and providers, and managing budgets. This project translates those occupation-level tasks into a student-sized deliverable. It is not an instruction to book an actual venue.
Write the purpose, audience, date, capacity, required services and decision owner at the top of the brief. Mark the sponsor as confirmed in the exercise so it is not confused with a lead or verbal expression of interest. In real work, the evidence and payment timing would need to support that label.

Calculate the result at 200 tickets
At 200 paid participants, ticket revenue is $8,000 and sponsor income $1,500. Fixed cost is $3,800 and variable cost $3,600, leaving $2,100 before unmodeled items. Total modeled costs are $7,400.
| Line | Calculation | Amount |
|---|---|---|
| Tickets | 200 × $40 | $8,000 |
| Confirmed sponsor | Given | $1,500 |
| Fixed costs | $2,500 + $900 + $400 | −$3,800 |
| Variable costs | 200 × $18 | −$3,600 |
| Before reserve | Revenue less modeled costs | $2,100 |
| Planning reserve | 10% × $7,400 | −$740 |
| After reserve | Planning remainder | $1,360 |
An illustrative contingency allowance of 10% of modeled costs is $740, leaving $1,360 after the reserve in the planning view. Ten percent is an assumption for this exercise, not an industry rule. A reserve is also not the same as an invoice already paid; keep planning allowances separate from actual expenditure.
If you change the expected headcount, recalculate variable costs and the reserve basis. Do not keep a static catering total while increasing registrations elsewhere in the model.
State which break-even question you are answering
Before a contingency reserve and the excluded charges, each paid participant contributes $22 toward fixed costs: $40 ticket revenue less $18 variable cost. Without sponsorship, $3,800 divided by $22 is about 172.73, requiring 173 whole paid participants to cover modeled costs.
With the confirmed $1,500 sponsor, the remaining fixed-cost burden is $2,300; divided by $22 it is about 104.55, requiring 105 whole paid participants. These are model-specific operating break-even counts, not thresholds that include every possible expense or a target surplus.
Do not count a pending sponsor as confirmed revenue simply to make the event feasible. Show an unsponsored scenario. Also build a dated cash schedule: a profitable event can still need funding before ticket proceeds arrive if venue or supplier deposits are due early.
Make the schedule a sequence of dependencies
A run of show should identify time, activity, owner, prerequisite and fallback. A line that says “10:15 keynote” is incomplete if no one knows who confirms the speaker, tests the microphone or controls the transition. The table is a compact original example, not a safety or venue-compliance plan.
| Time | Activity | Owner | Required before starting | Fallback question |
|---|---|---|---|---|
| 08:30 | Venue handover | Operations lead | Access confirmed | Who can authorize delayed setup? |
| 09:00 | Audio and display check | AV lead | Equipment and power approved | Which approved backup is available? |
| 09:45 | Registration briefing | Registration lead | Roster and help process ready | Where are unmatched registrations routed? |
| 10:00 | Doors open | Operations lead | Required checks complete | Who decides whether opening is delayed? |
| 10:15 | First speaker | Stage manager | Speaker and AV ready | Which prepared agenda change is approved? |
Keep the working schedule separate from the public attendee agenda. Staff may need to arrive much earlier, suppliers may have restricted access windows and teardown can continue after the last session. A student intern should escalate unresolved venue or safety requirements to the responsible professional rather than improvise them.
Do not substitute observed attendance for a supplier commitment
Suppose 200 tickets are sold and 180 people attend. Attendance is 90% of paid registrations, but the event may still owe catering for 200 if that was the guaranteed number at the agreed cutoff. A ten-percent no-show rate does not automatically reduce the bill.
Keep paid registrations, complimentary registrations, cancellations, refunds and actual check-ins distinct. Define whether a refund reduces the sold-ticket count and whether duplicate scans are removed. A single attendance total cannot reconcile cash received without those definitions.
Build an exception log with an owner and next update for incomplete sponsor materials, unconfirmed suppliers and accessibility requests. Protect attendee data and share only the information a team member needs. The log should help deliver the event rather than expose a public list of participants and private requests.
Finish with a packet that survives your absence
Deliver the brief, budget, break-even scenarios, dated cash needs, run of show and issue log. Include a version and last-updated time on the working documents. The useful test is whether another organizer can identify the next action and authority without calling you for every detail.
After the fictional event, reconcile budget, commitments and actuals. Explain whether a difference is a real saving, a delayed invoice or a scope change. Preserve open liabilities rather than claiming a surplus before every supplier is accounted for.
For an internship application, describe a real event you helped run or this explicitly independent exercise. State your own contribution and scale accurately. The ability to connect a budget to an operating plan is more convincing than a long list of event names without a defined responsibility.
