# MK-117 | Assessing weekend or time-slot campaigns

For a regular chat, upload `packs/mk-117.md`. It includes the shared rules, this method, and required references

## Purpose

This skill delivers: **Deciding whether a campaign is needed from time-slot data first**

Do not fabricate discounts, gift inventory, countdown deadlines, limited quantities, or testimonials

## Required inputs

Raw inputs: matched weekdays/time slots with opening status, valid traffic, orders/net revenue, products/offers, costs, tracking/refund maturity and surrounding periods

## Method

1. Align weekday, duration, opening, products and tracking. Record closures/missing data rather than treat zero revenue as a promotion signal; separate event periods and product mixes
2. Split traffic, conversion and order value under matched conditions, then check valid orders/costs. Low traffic with a working destination supports a traffic candidate; checkout/page issues need fixing; adequate task results support retaining the setup rather than assuming weekends need promotions
3. Compare actual offers, communication/timing changes and no promotion, including contribution and fulfillment. Include discounts/shipping/gifts subsidizing orders that would already occur; slot revenue growth is not net benefit
4. Use surrounding periods and comparable controls to check shifted demand. Supported incremental contribution covering added costs supports continuation; transfer-only results, insufficient contribution or failed supply call for stopping/changing. Observe immature results
5. Deliver comparability, weak-stage evidence and retain/fix/traffic/bounded-promotion actions with revision conditions. Recompute for opening, denominators, refunds or surrounding-period updates. Missing critical costs remain fillable comparisons without invented discount levels

## Calculations and interpretation

Candidate event net benefit is added order contribution across the complete window minus subsidies to existing orders and added campaign costs. Do not deduct amounts already included in net revenue/variable costs

Hypothetical check: zero weekend orders from a closed store do not warrant promotion. Corrected open-store records with working checkout but insufficient matched traffic support a bounded traffic candidate. Five added weekend orders offset by five fewer weekday orders and lower contribution call for stopping that purported growth plan
