Process Flow Design
 A process flow design can be defined as a
mapping of the specific processes that raw
materials, parts, and subassemblies follow as
they move through a plant.
 Common tools to design a process flow:
 Assembly drawing
 Assembly chart
 Operation and route sheet

Some Service Generalizations (1 of 2)
1. Everyone is an expert on services.
2. Services are idiosyncratic.
3. Quality of work is not quality of service.
4. Most services contain a mix of tangible
and intangible attributes (service package).
48
Irwin/McGraw-Hill 17
Some Service Generalizations (2 of 2)
5. High-contact services (described later) are
experienced, whereas goods are consumed.
6. Effective management of services requires
an understanding of marketing and
personnel, as well as operations.
7. Services often take the form of cycles of
encounters involving face-to-face, phone,
electromechanical, and/or mail interactions.

Failure Mode and Effects Criticality
Analysis (FMECA or FMEA)
Risk Priority Number (RPN) = Occurrence * Severity * Detection
 Occurrence = Frequency of failure mode (1=remote,
9=inevitable, 10=certain)
 Severity = How serious is the failure to the process; to business
results? (1=minor, 2-3=annoyance, 9-10=very high/most
severe)
 Detection = Likelihood that a defect will be detected by controls
before the next (subsequent) process (1-2=very high, 9=very
low, 10=absolutely cannot detect)
  
Irwin/McGraw-Hill 24
Service Recovery (Just in case)
 A real-time response to a service failure.
 Blueprinting can guide recovery planning
(fail points).
 Recovery planning involves training front-
line workers to respond to such situations as
overbooking, lost luggage, or a bad meal.

Service Recovery (Just in case)
“Empowerment can only take place when
every associate can personally assure
customer satisfaction every time!”
Gary Johnson
Irwin/McGraw-Hill 26
Service Recovery Processes:
Fundamental Questions to Ask
 Who are my customers?
 What is my product or service?
 What are my customer’s expectations and
measures?
 Does my product or service meet their
expectations?
 What is the process for providing my product or
service?
 What action is required to improve the process?
 What are my customer’s moments of truth?

 inability to store inventory
 Dealing will uncertainty in demand
 preemptive tactics
 flexibility
 forecasting
 use of waiting lines

Characteristics of a Well-Designed
Service System
1. Each element of the service system is consistent with
the operating focus of the firm.
2. It is structured so that consistent performance by its
people and systems is easily maintained.
3. It provides effective links between the back & front
office so that nothing falls between the cracks.
4. It manages the evidence of service quality in such a
way that customers see the value of the service.
5. The service system is:

cost-effective

user-friendly

robust

Editor's Notes

  • #2 There are two areas: Product Design Process Design After Engineering Release - Process Development Process Design Pilot Production Ramp up to full production Measuring Product Development Performance: Time to market Productivity Quality
  • #3 QFD - A tool to decide what the customer wants. - Changes Customer wants in the product specs (for new and existing products!) Voice of the customer - receive customer input from beginning Significantly reduces the number of changes after product introduction House of Quality A conceptual map (up to 100 Cust. Req. and 130 Engineering Considerations) Toyota started Ford uses
  • #5 Value Analysis/Value Engineering (VA/VE) - The same or better performance at a lower cost - Combine and standardize parts - reduce weight - Identifies unnecessary costs. A more formal approach, Design for manufacturing Design for Manufacturability Traditional – “we design you build” over the wall Current Engineering - work together simultaneously Design for Manufacturing and Assembly - Greatest improvements from reducing parts - keep in mind disassembly , keep all same material Global Product Design and Manufacturing Joint ventures - manu. in foreign country - coke Strategic suppliers - follow to new country - develop parts there and ship Design strategy - does it conform to new tastes - color of appliance etc
  • #7 Arrows should go both ways
  • #8 Conversion - Ore to sheet steel Fabrication - Steel into cans Assembly - put cans and Ingredients and lids together Testing - testing can for being sealed weight
  • #9 Job shop - Low volume machines grouped together Batch - Higher volume customer orders or forecasts grouped together Assembly Line - cars Continuous Flow - Food and beverage processing
  • #11 New term Must manage as one entity A virtual factory can be defined as a manufacturing operation where activities are carried out not in one central plant, but in multiple locations by suppliers and partner firms as part of a strategic alliance.
  • #12 Assembly chart - is a goes into chart Operation and route sheet - the path the product takes as it is being made
  • #17 1. Everyone knows what the service should be like 2. The type of service desired depends on the service not one standard method. 3. Good product slow service
  • #18 6. Must understand the effect of services 7. Package of Services - appointment follow-up dentist
  • #19 Facilities Based - Customer goes to Facility --- you come to class Field-based - Service goes to customer - tutor - Food comes to your house - webvan
  • #20 How do you compete Treatment of customer - A measure of quality Unique skill - part of service
  • #21 Low buffered core - ATM, Internet Purchases middle is Permeable High Reactive - Doctor, Barber, Dentist
  • #22 Integrates marketing and the service strategy Service does not necessarily move on matrix Mail contact - bank statements On-site technology - ATM Face to Face tight specs - Drive up Window Face to Face loose specs - React to Customer needs
  • #23 Identify customer contact points
  • #24 Appraisal costs:Cost of measuring quality of product Inspecting and testing Prevention costs: Quality Planning - Cause finding Internal failure costs: Scrap Rework External failure costs: Warranty and Liability
  • #25 After Failure – install Poke Yoke to avoid its reoccurance.
  • #26 After Failure – install Poke Yoke to avoid its reoccurance.
  • #29 Must prevent customer failure also Task - work that is done Is the task done correctly? checksheet, feedback Tangibles - Environment “was the waiting room clean?” numbers to call etc Treatment - Service, courteous? Correct price etc.
  • #31 The production line approach - Delivery is very standardized -- McDonald - Quasimanufacturing - backroom CQD Self-Service Approach - Customer as a participate - ATM, Vending machines, Catalogs, Self Service Gas Station Speedy Scan Banks expect you to fill out own paper work Personal Attention Approach face to face customization Service Guarantees - understandable, meaningful, easy to get
  • #32 Must vary capacity (production) to satisfy demand Call Centers, Full/Part-time help Preemptive tactics - offpeak incentives-- Disney, movie theater, appointment books
  • #33 Consistent performance - Service Quality Evidence - Tell people you are doing a good job. - on time arrivals - J D Powers report
