3 to 5 years of use or more
As good as or better than magma and other branded product Durable – resist minor bumps from transport without damage.
Easy to start.
Safe -  won’t cut , burn or harm users.
Maintains temperature, and can get hot enough to cook fish
Cost- expects to pay same or less than comparable branded product.
Use on a boat or in marine environment, that will likely be an unstable, vibrating platform in a corrosive environment, and it must stand up to this abuse.

Design validation and review:

Overall validation of all customer expectations, including:
Is the construction and design durable enough to last for intended lifetime of the product?
Does the product work well in real world use? Easy to mount, start, cook, clean?
Does the design get hot enough?
Is the design safe? Are there any safety features that can be added?
Is there anything we missed in the definition of the product?
Does the design hold up to real world use?
Is the design well documented and tolerance?
Are there any design changes that would reduce the manufacturing cost without compromising the performance?
Are there any design changes that could make the manufacturing process more reliable and repeatable?

Manufacturing validation and review

How do the first manufacturing samples compare to the design prototypes?
Can the process be refined?
Is there any variance in the quality of the product? Appearance, performance, etc. Packaging? Will it hold up to shipping? How can we prevent damage?

Mounts and accessories

Is unit’s mounting plate sufficiently stable?
Do all the mounts fit both BBQs?
Ease of assembling to mounts? Tool clearances?
Assemble to all accessories – check for fitment
Craftsmanship

Polishing
Dents-Scratches
Assembly, screw heads, etc. Hole locations
Ensure all fasteners are stainless steel and flush

Stainless Steel BBQ quality plan

This document will quantify and detail the quality standards that BBQ has for stainless steel barbeque products, specifically this document will apply to our models.

General expectations
*product will not injure consumers in normal usage, Surfaces that customers may come into contact with when installing using or maintaining must be free of sharp edges or burrs, Surfaces that are intended to be handled in normal use must remain cool as not to burn the user, These standards must be met to a 0.65% AQL level in all production batches.

*product must function as intended when initially removed from the package. Regulators must be operable and properly adjusted, Igniters must be operable and spark gap properly adjusted, these standards must be met to a 0.65% AQL level in all production batches.

*product must be free of major cosmetic blemishes and assembly problems ( scratches, dents, stains ,loose parts, fit / finish ) that materially reduce the value of the product to the consumer .Major cosmetic blemishes will be immediately apparent when inspecting .Major cosmetic blemishes will be immediately apparent when inspecting the product. These standards must be met to a 2.5% AQL level in all production batches.

*product must be free of minor cosmetic blemishes and assembly problems ( minor dents, more than 5 minor scratches, minor stains, small loose parts, minor ( fit / finish issues ) that affect the customer’s perception of the quality . Minor cosmetic blemishes will be apparent with detailed inspection of the product, these standards must be met to a 6.5%AQL level in all production batches.

*product must be free of minor scratches, No more than 25% of production units may be affected by minor scratches (one or more).

*Product will be securely packed in such a way that normal handing and transportation does not damage the product, all product components (grilles, etc.) must be secured within the product using proper packaging techniques.

We will have production units inspected by mutually agreed upon 3rd party product verification firms, or designated and agreed upon our Associates, We will inspect a random sample of product based on specific inspection points and criteria as defined in this document, The sample will be pulled from ready to ship inventory as defined by general inspection level Ⅱ in MIL 105E.


All production batches must pass inspection and receive approval before fulfillment of the respective purchase order.


Inspection Criteria

  1. Critical –AQL:0.65%


    1. Sharp edge or burrs on unit –Unit must not cut or scratch users in normal handing or use, Run fingers over all edges of product. Use moderate pressure, as would be applied if user was to pick up unit by corners. We will study this and try to find and industry standard test specification detailing sharp edges for future production runs.
    2. Functionality test-Unit must function as designed out of box. Connect unit to propane gas source, turn on regulator and start unit using push button igniter. Unit should start within the first 5 presses of the button. The flame should be mostly blue, with slightly orange tips. Turn the regulator off and the unit should extinguish within a few moments and not leak propane.


    1. Sharp edges or burrs on wire grill edges-Grille must not cut or scratch users in normal handing or use .Run fingers over edges of wire grill in both axis (both from right to left on the grill, and fore / aft across the ends of the wire).


  1. Major –AQL:2.5%


    1. Major cosmetic defects on logo-Black resin filling our Logo should be firmly attached to the logo and should not easily flake or peel out of the logo. We should be highly polished and not contaminated by black resin, Use proper lighting and inspect from several angles looking for defects.
