Operations Planning Lecture #7
Forecasting • Estimating future events • HasNOvalue to an organization unless the forecasts are included in organization’s decision-making process
ContingencyPlanning • Preparation of a course of action to meet a situation that is not expected, but that, if it occurs, will have a significant impact on the organization.
Contingency Planning • Example: Sales plummet 20% in a quarter
Operations Planning Your example?
Contingency Planning • Event could be positive • A 20%increasein sales in a quarter
Keys to Successful Contingency Planning • Identify contingent events • Establish an action point • Develop new strategies and plans (shhh!)
Identify Contingent Events • A significant decline in sales • A product recall
Establish an Action Point • When sales decline at least 20% in two consecutive quarters • When more than 5,000 vehicles of any single model are recalled
Strategies and Plans • Lay off 30% of production line workers and first line supervisors • Seniority? • Merit rating?
Layout Patterns • How the flow of work is laid out for efficient production and minimal “bottlenecks”
Layout Patterns • Process Layout • Product Layout • Fixed Position Layout
Process Layout(Functional Arrangement) • Manufacturing of Chairs, Tables, and Hat Racks
Chairs, Tables, Hat Racks Sanding Cutting Finishing Assembling
Process Layout Example • Chairs, tables and hat racks all pass through the four functional areas, but not necessarily in the same sequence. • Major advantage is economy of scale in the functional areas.
Product Layout • As product lines increase, and/or volume increases, this form tends to replace the Process Layout
Product Layout • Chairs, Tables, and Hat Racks
CHAIRS Cut Assembly Sand Fin TABLES Cut Sand Fin Assembly HAT RACKS Cut Sand Assembly Fin
Product Layout Example • Can make a change to any product line without affecting production of other products. • Major disadvantage is duplication of resources in the production areas.
Fixed Position Layout • Product remains stationary • Labor and tools come to the product
How Many Units to Produce? • Known (or firm) orders • Forecasts of demand
