assembly

    What type of assembly is needed? What are the overall performance requirements for assembly (elasticity, high peel strength, etc.)?

substrate

    What is the material used for bonding? Consider the surface condition of each material (rough, smooth, etc.)

workmanship

    What is the current assembly and manufacturing process? Does this solution need to adapt to the current process/equipment, or will the process/equipment change? What are the various processing steps? How fast does the component move to each step? Do component adhesives need to be repositioned at any time? If so, why? When was it? Are there any environmental, regulatory, or workplace safety restrictions?

end use

    How and where will the final product be used? Will assembly be exposed to harsh environments such as ultraviolet radiation, chemicals, high humidity, extremely high or low temperatures, etc?

cost

    Where can improvements be made during the assembly process (manpower, reduced processing steps, materials, assembly line, etc.)?
