Product Design - Checklist

FICCI CE

Product Design Controls

Product design controls can be categorized in 3 parts

• Means of knowing the product

• Means of testing designs

• Means of regulating designs

FICCI CE

Means of knowing the product

Do the designers know the variety of application of the

product.

Do they have complete information on the operating

environments.

Do they have access to the user to discuss applications.

Do they know the potential field misuses of the product.

FICCI CE


Do they have clear understanding of product requirement

on :-

Performance

Life

Warranty period

Reliability

Maintainability

Accessibility

Safety

Operating costs

FICCI CE


Have the non quantitative features of the product been

defined in some manner?

Do the designers know the level of product

sophistication suitable for the user involved?

Are adequate design guidelines, standards, handbooks

and catalogues available?

Do the designers understand the interaction of their

part of design with remainder of the design?

FICCI CE


Do the designers understand the consequences of a failure

or other inadequacies of their designs on:-

1. The functioning of the total system

2. Warranty costs and

3. User costs ?

Do they know the relative importance of various

components & characteristics within components?

Do the designers know what are the manufacturing

capabilities relative to the design of tolerances?

FICCI CE


Do the designers derive tolerances based on

customer/functional needs or just use standard tolerances?

Do the designers know the shop and field costs incurred

because of incomplete design specifications or designs

required in change?

FICCI CE

Means of testing designs

Do the designers have the means of testing their design

with regard to the following :-

a. Performance & reliability tests

b. Tests for unknown design interaction or effects

c. Pilot run

Is their an independent review of design?

Have the detailed drawings been checked?

FICCI CE


Do the designers record analysis for the design?

Do the designers receive adequate feedback from

development tests, manufacturing tests, acceptance tests and

user experience?

Are the results quantified where possible including

frequency of problems and costs to the manufacturer and

user?

FICCI CE


Does failure information contain sufficient technical details

on causes?

Are the designers aware of material substitutions or

process changes?

Do the designers receive notice when their designs

specifications are not followed in practice?

FICCI CE

Means of regulating Design

Have the designers been provided with the means of

regulating the design process?

Are they provided with information on new alternative

materials or design approaches?

Have they been given performance information on previous

designs?

Are the results of research efforts on new products transmitted

to the designers?

FICCI CE


Are the approvals required from the designers to use

products from the new suppliers?

Do the designers participate in defining the criteria for

shipment of the product?

Can the designers propose changes involving trade-offs

between functional performance, reliability and

maintainability?

FICCI CE


Are designers told of changes to their designs before they are

released?

Have causes of design failures been determined by thorough

analysis?

Do designers have the authority to follow their designs

through the prototype stage and make design changes where

needed?

Can the designers initiate design changes?

FICCI CE


Are field reports reviewed with designers before making

decisions on design changes?

Do designers understand the procedures and chain of

command for changing a design?
