Service capacity
- Capacity must be available when service is needed - cannot be stored - Service must be available at customer demand point - Much higher volatility is typical
Maturity
-ATO and MTS -peak sales -cost per customer lowest -profits high -mass market -stable number of competitors
Speed
-Ability to deliver services or products quickly -capability to react to changes in customer needs or dates
Order winners
-Attributes that differentiate a company's products -ex: fuel efficiency in a car, or leather seats in a car
Manufacturing in most supply chains examples
-CPA firms: forms and office equipment -service repair firms: products and parts -restaurants: appliances and food processing and packaging
SCOR model- Deliver
-Describes the activities associated with the creation, maintenance, and fulfillment of customer orders -includes receiving, validating, and creating customer orders, scheduling order deliveries, picking, packing, and shipping, and invoicing customers
ERP concepts
-ERP is not just a computer system to manage a company -it is a process of planning and execution involving integrated functions within the business -the ERP computer system is a tool to more easily accomplish the erp system integration
Introduction
-ETO -low sales -high cost per customer -financial losses -innovative customers -few competitors
Risk management program
-Firms operations should have a risk management program that can anticipate variation -should work closely with their suppliers to safeguard their supply chains against future supply chain failures
Main tools beyond market insight
-Flexibility and responsiveness (speed) -buffer capacity for agility -buffer inventory for responsiveness
IoT
-Internet of Things -often associated with industry 4.0 -looks at processes, data analysis, people interaction and decision making
Capital budget
-Is about prioritizing projects to accomplish the overall planning process of the company -determine whether investments such as new machinery etc are worth investing in -annual process
Growth
-MTO -increasing sales -cost per customer falls -profits rise -increasing number of customers -more competitors
Decline
-MTO and ETO -falling sales -cost per customer low -profits fall -customer base contracts -number of competitors fall
Barometric measures
-Metrics that are the same in every business -should never go away
Hoshin Kanri strategic planning
-Mission to senior management to middle management to workers -emphasis on feedback loop, employee involvement, regular reviews, doable goals
The functional fields of business are
-Operations and Supply Chain Management -Marketing -Finance -Sales
Goods and service continuum
-Products are typically neither purely service- or purely goods-based -goods and services exist on a spectrum where some percentage is a good and some percentage is a service
SCOR model- source
-Sourcing is the process of identifying the suppliers that provide the materials and services needed for the supply chain to deliver the finished product(s) desired by the customer(s). -This phase involves not only identifying reliable suppliers but also building a strong relationship with those suppliers. -Supply chain managers must also develop pricing, shipping, delivery, and payment processes with suppliers and create metrics for monitoring and improving the performance
Decision tree
-a schematic model of the sequence of steps in a problem and the conditions and consequences of each step -help analysts understand the problem and assist in identifying the best solution
KPI for operational strategy
-accuracy of cost per plan facility -accuracy of revenue plan per facility and overall -accuracy of profit plan
Inventory strategy
-all manufacturers have demand differences in units offered -strategy to build and hold inventory in these categories is key
Production planning metric
-capacity (build rates) by product family
Rules for determining product families
-common constraint in the process such as product line -common components -common manufacturing or inventory strategy -product types -product characteristics -product size -product volume (huge ones can be a family of its own, smaller volume can be combined) -market segment -distribution channel -customer

Relationship between service capacity utilization and service quality
-critical and directly linked -service requires a lower capacity utilization plan to assure higher levels of service
Level 1 of SCOR
-defining scope -geographies, segments, context
Two main sides to business
-demand -fulfillment
Operations management planning includes
-demand planning and production planning feeding into master production scheduling -MPS feeds into materials planning -data accuracy

Timeline of SCOR
-developed by consulting firm -endorsed by supply chain counsel -supply chain counsel acquired by APICS -APICS is now a part of ASCM
Operations management
-everything you brought to class this morning was managed by operations management -involved in every business you have will work in during your career -even personal life: planning and scheduling, education, vacations, careers
Supply chain flows
-flows represent the direction and purposes of process sequences -supply chain management includes both directions (up and down stream)
Enable hierarchy
-for each level 1 process, there is often 2 or three more differentiating level 2 processes supporting it -each level 2 process contains level 3 process elements -these hierarchical relationships provide process classification

High performance requires 2 things
-good plan -good execution
Product families
-groups of products that have similar processing requirements -general recommendation is to manage the product families to a total of 6-12 families per S&OP process -all products within a product family must be stated in the same unit of measure
Blue Ocean Strategy
-highly competitive markets are known as red oceans -companies are encouraged to reinvent their markets by creating a blue ocean strategy where new elements of competitive advantage are introduced into existing markets
Implementing an ERP system
-huge undertaking -culture, process design, discipline, and accountability is required
Theory of constraints- resolving
-identify the most pressing constraint (could be internal or external) -change the operation to achieve maximum benefit (exploit) -make sure the other portions of the process are supportive of the constraint (place buffers at the beginning, at the constraint, and at finished goods) -explore and evaluate ways to overcome the constraint (increase capacity by investment of supplementing) -repeat until constraint levels are acceptable

Operations execution includes
-materials planning feeds into procurement process and shop floor process, which feed into logistics, distribution, and customer service -procurement process leads to supply chain management
Diagnostic measures
-metrics that change as problem solving evolves -when these measures show good performance and the process is trusted, these can go away
Order qualifiers
-necessary attributes that allow a firm to enter into and compete in a market; a firm's strategy must account for these necessities -quality is generally an order qualifier in today's markets: if you don't have it, you don't get to play the game -ex: kia motors had to increase safety standards to compete in markets
Why product families
-not unusual to have a million SKUs in a business -top management is not going to want to spend time regularly reviewing every SKU -includes final assemblies, subassemblies, fabrications, purchased components, and raw materials
Success depends on
-operations related strategy -processes to deliver products and services (making sure the capacity and materials are available) -analytics to support the decisions needed
ERP excellence
-overall performance -top management planning -operations management planning -data accuracy -execution of plans -management of human capital

Variation in operations management
-there is an enormous amount of variation in operations management -customer demand variation, competition and associated variation, technology and associated variation -manufacturing and service process variation
Master scheduling metric
-weekly SKU level schedule accuracy by product line
SCOR and Enable cont
-when conducting a SCOR project, SCOR users may decide to move some lower level processes into other process sections -SCOR can serve as a flexible and customizable model that can be applied to multiple industries and situations, so the framework process locations are not rigid -if processes are moved, SCOR users should be careful not to duplicate processes
