Opening Question
2
If you managed a restaurant, what information would you want to know to help you predict how many guests to expect at tomorrow’s meal services?
Forecasting Process
3
Forecasting Process
• Historical quantitative data come from POS system or reservation/walk-in book
• Qualitative data should be recorded daily in a log or POS system
• Qualitative data includes: ―weather, ―special events, ―conventions, ―holidays, ―construction project, ―competition changes, ―marketing promotions―…anything that might explain business fluctuations
4
Trends
• Start with customer count from the same day of the week from the prior week or the prior year.
• Adjust based on historical trend percent increase or decrease
5
% changeCurrent customer count– prior count
Prior customer count=
Example 12a
6
Restaurant saw 347 customers the first Friday in March this year and 360 the first Friday in March last year. What is the percent change from last year?
% change347-360
360= = -0.036 (3.6% decrease)
Using Trends
• Trends only significant if repeated over and over each same day of the week
• Manager uses trend to calculate initial forecast
New Customer Count = Prior Count X (1 + percent change in decimal
form)
7
Example 12b
New Count = 340 X (1 + 0.014) = 344.8 or 345
8
Business has consistent trend of 1.4% increase over last year’s customer counts. If first Friday in March last year saw 340 customers, how many should be forecast for the first Friday in March this year?
Rolling Averages
C = Customer count for that periodN = total number of periods counted
9
Rolling Average CountC1 + C2 + C3…+ CN
N=
Use rolling averages when no trend is consistent across weeks.
Example 12c
10
Business forecasts using rolling averages over 4 weeks. Guest counts for past 4 weeks have been 418, 437, 398, and 414. What is forecast for upcoming week?
Rolling Average418 + 437 + 398 + 414
4= =
417
Adjusting for Qualitative Data
• Manager adjusts initial forecast based on qualitative data
• Keep adjusting as new data comes in (weather report changes, for example)
• Forecast 1-2 weeks our for schedule, 2-3 days out for ordering, 1 day out for kitchen production schedule
11
Evaluating the System
12
Constantly compare the forecast to the actual guest count to learn from mistakes and to make more accurate forecasts in the future.
Forecasting Sales
• Converting customers to revenue helps to budget and control costs
• Average Check = amount of revenue the average person generates on a check
• Can calculate average check by server to identify strong servers or average check by day, week, or meal period to inform when to offer promotions
13
Average Check
14
Average CheckRevenue for a Period
Guests for that Period=
Example 12d
Average Check = $12,385 ÷ 1,104
= $11.22
15
Over past 4 Mondays, restaurant has served total of 1,104 guests for lunch and brought in $12,385 from those 4 periods. What is average guest check for Monday lunch during this period?
Uses for Average Check
• It is a control tool. If it changes much over time, manager should research why and correct problems or reinforce results
• When seating is limited, increasing average check may be only way to improve profit
• Average check can forecast revenue
Forecast Revenue = Forecast Guests X Average Check
16
Example 12e
Forecast revenue = 3,700 X $47.58
= $176,046
17
Restaurant with average check of $47.58 forecasts 3,700 guests next month. How much revenue should manager expect next month?
Using Forecast Revenue
18
Using forecast revenue and target food cost %, beverage cost %, and labor cost %, manager can determine budget in dollars for a given period of time.
Seat Turnover
19
When seating is maxed out, manager can serve more customers in a period by increasing the seat turnover or number of customers per seat in a given period.
Seat TurnoverCustomers Served in a Period
Total Seats in Dining Room=
Example 12f
Seat Turnover = 280 ÷ 120 = 2.33
20
Restaurant has 120 seats in dining room, but serves 280 guests at dinner. What is seat turnover for dinner?
Seat Turnover (cont.)
• Impacted by slow kitchen service or understaffed or slow dining room staff
• Guest service should not be so rushed that it reduces check average; service must remain efficient but comfortable for guests
• Seat turnover can be used with forecast to decide how many (if multiple) dining rooms to open or when to expand dining room
21
Menu Mix
• Menu Mix % = % of sales that come from each menu item
• It is usually divided by menu category and is relatively consistent with a meal period across same days of the week
Caveat: may change seasonally or with weather, and definitely with menu change
22
Menu Mix Formula
Note: Number of each item sold and total sold come from POS system or sales receipts
23
Menu Mix %Number of that item sold
Total number of items sold=
Example 12g
Menu Mix % = 37 ÷ 140
= 0.264 or 26.4%
24
Restaurant typically sells 140 desserts each Monday. Of those, 37 are usually sorbet. What percent of desserts are the sorbets?
Menu Mix (cont.)
• Menu mix usually calculated against total in a menu category
• Manager must calculate % of guests who purchase food from each menu category
25
% buying categoryGuests buying that category
Total guests=
Example 12h
% buying dessert = 140 ÷ 330
= 0.424 or 42.4%
26
Of the 330 guests in a restaurant one night, only 140 buy dessert. What percent bought dessert?

Example 12i
1. No. ordering dessert = 370 X 0.42 = 155.4
2. No. of sorbets = 155.4 X 0.37 = 57.5 or 58 sorbets
29
Historically, 42% of guests order dessert Thursday night. Of those, 37% are sorbet. How many sorbets should the pastry chef plan for next Thursday if the guest forecast is 370 guests?
Forecasting Kitchen Production
• Manager uses forecast menu mix sales to plan kitchen production
• Manager should adjust forecast based on qualitative data, desire to have a buffer, or desire to run out of certain foods to avoid leftovers.
• Accurate production schedule minimizes leftovers, waste, purchases, and labor costs
30
Menu Analysis for Increased Profitability
• Making the most profitable items the most popular ones helps to maximize overall profit
• Menu Analysis is best done over a long time period (several months or a year)
31
Menu Analysis is process through which managers compare each menu item’s profitability and popularity
Calculating PopularityWork with only one menu category at a time…
32
Calculating Profitability, Part 1
Contribution = Item Sales Price – Item Food (or
Margin (CM) Beverage) Cost
33
Menu CM = No. sold (for an item) X CM (for that item)
Calculating Profitability
34
Still working with only one menu category at a time…
Using Menu Analysis
• To make an item more popular: move its location on the menu or suggestive sell it.
• To make an item more profitable: adjust its portion size or sales price.
• Can always rework a menu item or replace it entirely
35
Menu Analysis Categories
36
Star
• high popularity, high profitability. Leave these items alone.
Plowhorse• high popularity, low profitability. May increase sales price, reduce food
cost, or leave alone if it is a signature dish/draw.
Puzzle• low popularity, high profitability. Relocate on menu, highlight on
menu, rework menu description, suggestive sell.
Dog• low popularity, low profitability. Often requires a change: increase sales price, suggestive sell, or replace
with a dish that still meets the needs of the customers who used to order the dog. (e.g., replace a vegetarian dish with another vegetarian dish)
Reconciling Kitchen Production with Sales
• Kitchen production schedules can be used to reconcile food produced against food sold.
• All food prepared by kitchen must be accounted for to protect against theft.
• Kitchen Production Sheet uses menu mix % and forecast to predict how many of each dish will be sold.
37
Example 12j
Number ordering dessert =130 X 0.42
= 54.6 or 55 guests ordering dessert
38
Restaurant forecasts 130 guests for dinner tomorrow. 42% of guests usually order dessert. Use chart on next slide to calculate the number of each dessert forecast to be sold.

Converting Forecast Menu Mix Count to Kitchen Production Schedule
41
Manager must adjust numbers to account
for qualitative factors
Chef must factor in prior leftovers (portions on hand)
and create a “buffer” in case forecast is off slightly
Kitchen Production Sheet
42
Adjusted Forecast• made by manager the day before service based on most recent qualitative
data
Portions on hand
• reusable leftovers from prior shift
Buffer• determined in advance by chef to cover most services without running out of
a menu item
See Table 12.3 in the Text.
Kitchen Production Sheet
43
Portions to Prepare
• adjusted forecast + buffer – portions on hand
Total Available
• portions to prepare + portions on hand
Leftovers• is completed at end of shift to record food not sold (for reconciling sales) and to ensure none are “lost” before
next shift• Having too many leftovers regularly is cause to adjust buffers or forecasting processes
See Table 12.3 in the Text.

Kitchen Production Sheet Notes
• If kitchen runs out of food and additional portions are made during service, “additional production” should be recorded on the form
• If a dish is 86’ed, manager should record when this occurs to determine if it represents good or bad forecasting
45
Mishaps and Sales Reconciliation
• When no errors occur during service, dishes sold = number available for sale – leftovers
• Errors often occur and should be recorded on a Food Mishap Report a.k.a. Void Sheet
• Void Sheet lists all items rendered unusable during service; for each item lost, it includes
―the name of server, ―item name, ―reason for void, ―and possibly check number, date, and time of
mishap
46
Voids
• Every void must be accounted for to ensure it isn’t being stolen
• Trusted employee or manager should verify (visually) that each item is legitimately ruined before entering it on Void Sheet
47
Voids occur when food is dropped on floor, customer rejects it for improper cooking, customer dislikes the taste, or cook ruins it and removes it from circulation
Voids
• Lots of a voids coming from a single employee suggest the employee needs retraining
• Lots of voids across the staff may suggest an understaffed business
48
Reasons for voids:
Food and Sales Reconciliation Form
At end of service or day, manager should complete a food and sales reconciliation form to confirm that all portions prepared by kitchen are accounted for as sales, voids, or leftovers.
49
See Table 12.5 in text, which shows sample food and sales reconciliation
form.

Food and Sales Reconciliation Form
• Info on Form comes from Kitchen Production Sheet, Void Sheet, POS system/guest checks, and physical inventory of kitchen stations
• Total Output (portions sold + voids) should match Portions Consumed (sent out from kitchen)
• Any discrepancy should be investigated
51
Reconciliation Form (cont.)
• Regularly forgetting to enter voids or checks missing from the same employee may be a sign of theft or signal a need for retraining
• POS systems record which server orders each dish, so missing checks are not an issue. Missing food is easier to track to a specific server.
