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, repair, modification, etc.

 

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?"

  1. What should Frisby tell the mayor?
  2. How should the city purchasing manager help solve the fire equipment dispute to the satisfaction of the fire chief and the city council?

 

 


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.
