CLASS 3 - THE DESIGN PROCESS
ROLE IN NEW PRODUCT DEVELOPMENT
Review:
Purchasing process consists of three phases:
• Pre-award: Requirements Determination
• Solicitation and Award: Purchasing/RFP, Source Selection (technical
and price), Award
• Post-award: Contract Administration and Management
Early purchasing involvement
(EPI) and use of cross-functional teams:
• Reduce time to procure
• Increase quality of products (both purchased materials and end-products)
• Produce more favorable cost returns on purchased materials
Purchasing involvement
in the Design Process:
• Facilitates identification of new components
• Supports location of potential vendor-partners (considering product
suitability, quality, certainty of delivery, cost, service)
Purchasing's role is expanded
by:
• Use of Design or Project Teams
• Employ materials engineers as buyers
• Co-locate buyers with design/engineering staff (permanent or matrix)
SPECIFICATIONS
Quality is conformance to specifications
therefore; specifications are the foundation of Quality of Performance.
Quality is related to suitability and cost
(not price), rather than
intrinsic excellence (i.e. a diamond)
Cost (life cycle cost = price + related
future expenditures, i.e. maintenance,
Quality is determined by the TECHNICAL consideration
of
suitability and the ECONOMIC consideration
of cost and
availability.
Technical considerations are the responsibility of
the designers, jointly with the marketers
Economic considerations are the responsibility of
the purchasing department, jointly with the marketers
Purchasing Dept. has management responsibility
to challenge
requirement but not to unilaterally change
it
How does a PO describe
a requirement?
• By market grade (natural products i.e. lumber, food products)
• Brand name (or equal)
• Commercial standards (Grade 8 bolts)
• Design specification
• Performance specification - Functional specification
• Review of submitted samples
• Qualified products list
Most common methods include:
• Brand name: 25%
• Commercial Standard: 26%
• Specifications (Design or Performance): 31%
Conventionally, a purchase description calls
for:
Only the minimum product needed to perform
its intended function should be stated
Specifications must consider-
Function (design)
Consumer acceptance (marketing)
Economy to produce (manufacturing)
Materials availability, cost (procurement)
Views within the organization may be in
conflict:
• Marketing wants product to be unique
• Engineering wants product excellence
• Production wants ease of construction
• Purchasing wants materials availability, low cost
Because of these considerations, Balanced
Specifications, i.e. specifications that address and satisfy the total
requirements of the organization, must be developed by:
• Early Purchasing Involvement
• Formal Committees to review specifications
• Informal involvement (i.e. "challenges to designs/requirements)
• Purchasing Coordinator to perform liaison between Purchasing, Design,
Production.
• Standardization of Purchase Descriptions whenever possible.
Specifications must consider:
1. Marketability
and product appeal
2. "Make
ability"
3. "Inspect
ability" (ability to test and comply)
4. "Storability"
(receipt, storage, shelf-life)
5. Scheduling
of production
6. Availability
(to purchase competitively, timely, reliably)
7. "Substitutability"
(when necessary due to unavailability)
8. Cost
9. Standardization
(Case:
Gotham City Buy's Fire Engines)
GOTHAM CITY BUYS FIRE ENGINES
Mayor Harold Goodfellow of Gotham City is faced with a touchy situation
involving a City Hall dispute between his newly appointed city purchasing
manager, Ed Frisby, and Gotham's venerable fire chief, Willard Clark.
It all started soon after Mayor Goodfellow hired
Frisby following a favoritism scandal linked to the purchases of the previous
city purchasing manager. To prevent a recurrence of the problem, the mayor
gave Frisby instructions to set up a standards committee and gave the new
city purchasing manager full backing in enlisting assistance from other city
employees.
In accordance with the mayor's instructions, Frisby
formed a committee consisting of a Fire Department representative selected
by Chief Clark, an engineer from the Public Works Department, a woman from
the Finance Department, and himself. The group began working on the high value
purchases, and the first on the agenda was the purchase of ten new fire pumping
engines and five extension ladder trucks, involving an estimated expenditure
of approximately $600,000 for the pumpers and another $1 million for the ladder
trucks.
Frisby got together with the standards committee
and representatives of firefighting equipment suppliers. Through these meetings
the committee prepared open specifications, to which all agreed.
Bids were received, opened publicly, and then analyzed.
The purchasing manager, in accordance with the unanimous findings of the committee,
recommended that the city accept the lowest bid that met the minimum specifications
in all respects. There was considerable spread between the lowest and the
next lowest bids.
Then the trouble began. Shortly after making this
recommendation, purchasing manager Frisby learned that Chief Clark had sent
a resolution to the City Council recommending rejection of all the bids and
award of the contract to another higher-priced supplier. Clark told the City
Council that he would not be responsible for fighting fires unless his selection
of equipment was approved by the council.
The mayor called Frisby. "Look, Ed," he
said, "I'm in the middle of this fire equipment dispute. I think you're
right in this hassle, and I want to support your work on the standards committee.
But Chief Clark is a respected old-timer around here, and I think he's got
some of the City Council on his side. Do you have any ideas on how to settle
this difficulty and keep the chief happy too?"
STANDARDIZATION
TWO TYPES OF STANDARDIZATION:
1. Of things (size, shape, color, physical properties,
chemical properties, performance characteristics, etc.)
2. Of Practices and procedures (managerial standardization)
As production process moves
from Job Shop through Line Flow to Continuous Process Flow methods, opportunities
to standardize FINISHED PRODUCTS increase. As this occurs, materials, parts and subassemblies
used in each process can be increasingly standardized.
How does standardization
reduce costs in a manufacturing industry (or any industry)? (p. 181):
Permits purchase of fewer items, in larger quantities, at lower prices,
thus, acquisition, handling, quality costs are minimized.
Kinds of Industrial Standards:
• International Standards Organization (ISO)
• National Bureau of Standards (NBS)
• American National Standards Institute (ANSI)
• American Society for Quality Control (ASQC)
• Society of Automotive Engineers (SAE)
SIMPLIFICATION
Simplification means reducing
the number of standard items a firm uses in its produce design and carries
in inventory.
Simplification encourages
broad application of the same standard materials throughout a range of product
lines.
