Chapter 6 Food Production
Functional Subsystem: Food Production • Food production is the preparation of menu items in the needed quantity & with the desired quality. • Quantity – Distinguishes foodservices production from home or family food preparation. • Quality – Aesthetic, nutritional, & microbiological safety aspects of a food product. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Subsystem Objectives • Primary: Transform human, material, facility, & operational resources into outputs. • Secondary: • Product/service characteristics • Process characteristics • Product/service quality • Efficiency: • Effective employee relations & cost control of labor • Cost control of materials • Cost control of facility use • Customer service: • Produce quantities to meet expected demand • Meet delivery date for products or services ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Decisions • Includes forecasting, planning, & production scheduling. • Synthesis of quantity, quality, & cost objectives. • Product characteristics • Production process characteristics • Establishment of standards of quality ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Forecasting • Primary result of forecasting should be customer satisfaction. • Production Demand • Overproduction – Production of more food than is needed for service. • Underproduction – Production of less food than is needed for service ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Forecasting • Quantity Demand • Estimate number of customers or the number of servings. • Essential to use suitable forecasting model. • Examples: • Historical records • Intuition • Complex models requiring large amounts of data ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Forecasting • Historical Records • Effective production records should include: • Date & day of the week • Meal or hour of service • Notation of special event, holiday, & weather conditions • Food items prepared • Quantity of each item prepared • Quantity of each item served • Provide fundamental base for forecasting quantities when the same meal or menu item is repeated. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Forecasting Models • Criteria for a Model: • Cost – expenses of both development & operation. • Required accuracy –accuracy of its predictions of future occurrences. • Relevancy of past data–relationship of past & future data. • Forecasting lead time – length of time into future the forecasts are made. • Underlying pattern of behavior – actual occurrences follow some known pattern. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Types of Models • Most common model categories: • Time series • Casual • Subjective • Trends & seasonality in the data must be considered. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Time Series Model • Assumption that actual occurrences follow an identifiable pattern over time. • Suitable for short-term forecasts. • Frequent time series models: • Moving average forecasting model • Exponential smoothing forecasting model ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Moving Average Forecasting Model • First point: average of number of portions sold for the last five or more times the menu item was offered. • Second point: average of dropping the first number & adding the most recent number of portions sold to the bottom of the list. • Continue process for all data. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Moving Average Forecasting Model ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Exponential Smoothing Forecasting Model • All past data are considered in smoothing process. • More recent data are given more weight. • Requires only a few pieces of data to update a forecast. • Easily programmed & is inexpensive to use. • Rate at which the model responds to change can be adjusted mathematically. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Casual Model • Assumption that an identifiable relationship exists between the item being forecast & other factors. • High costs for development & use. • Popular for medium- & long-term forecasts. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Regression Analysis Forecasting Models • Most commonly adapted. • Includes: • Dependent variables – items being forecast. • Independent variables – factors determining the value of the dependent variables. • Requires a history of data to permit plotting over time. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Subjective Model • Used when relevant data is scarce or patterns & relationships between data do not tend to persist over time. • Delphi technique • Market research • Panel consensus • Visionary forecast • Historical analogy ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Scheduling • Time sequencing of events required to produce a meal. • Planning stage: • Forecasts are converted into the quantity of each menu item to be prepared. • Distribution of food production to supervisors in each work center. • Action stage: • Supervisors prepare a production schedule. • Items are assigned to specific employees. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Schedule • Should include: • Employee assignments • Preparation time schedule • Menu item • Over- & underproduction • Quantity to prepare: forecast amount for each menu item. • Substitutions • Actual yield: portion count produced by the recipe. • Additional assignments • Special instructions & comments • Pre-preparation ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Production Meetings • Should be held daily with employees in the production unit. • Employees encouraged to discuss the effectiveness of the schedule. • Free discussion of work loads. • Conclude with discussion of the production schedule for the following three meals. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Ingredient Control • Begins with purchasing, receiving, & storage of foods. • Continues through forecasting & production. • Ingredient assembly – area designed for measuring ingredients. • Standardized recipes – provides assurance that standards of quality will be consistently maintained. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Advantages of Centralized Ingredient Assembly • Contributes to the cost reduction & quality improvement. • Redirection of cooks’ skills away from collecting, assembling, & measuring ingredients to production, garnishing, & portion control. • More efficient use of labor. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Centralized Ingredient Control • Control of unused portions is facilitated because storage is located centrally rather than in various work units. • Ability to combine tasks for two or more recipes using similar ingredients. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Function of the Ingredient Room • Primary function is to coordinate assembly, pre-preparation, measuring, & weighing of the ingredients. • Availability of appropriate equipment will help determine the activities to be performed. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Ingredient Room Organization • Should be located between the storage & production areas. • Necessary equipment includes: • Refrigeration • Water supply • Trucks or carts for assembly & delivery • Worktable or counter • Scales ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Ingredient Room Staffing • Employees must be: • Literate • Able to do simple arithmetic • Familiar with storage facilities • Responsible for receiving, storage, & ingredient assembly. ©2004 Pearson Education, Inc. Upper Saddle River, New Jersey 07458
Ingredient Room Staffing • Ingredient assembly personnel considerations: • Size of operation • Frequency & time of deliveries • Size of ingredient room & location of other storage areas • Type, number, & complexity of menu items • Number of workstation to be supplied • Schedule for delivery of ingredients to production & serving areas • Extent of pre-preparation performed in ingredient assembly area ©2004 Pearson Education, Inc.
