Initial Specification

Electronic Products
 

 

An Initial Product Design Specification (PDS) is a list of everything about your product. Specifications are used to tell the potential buyer about the product. If you return back to the example ISR of the Circuit timer it states things about the user, testing etc.. When you have produced your ISR you will have came to a number of conclusions:

  • What your product will be used for.
  • What size it is going to be.
  • What type of decorative finish will be applied.
  • How you will ensure safety.
  • How will it be powered.
  • How will it be activated.
  • What it does 30 beats a minute, variable etc...
  • How you will ensure safety of both the components and the casing.
  • Cost Etc… Etc… Etc…

The specification again may be developed as you work through your project. Changes that may be needed during the project have an effect on the specification, you may want to remove some part of the design and change something else. Make notes on the reason you changed something and record it under design development and ongoing changes.
The Final Product Design Specification will arrive when you have completed all your designing, development and testing and had some user feedback. 


For a more comprehensive list to help with your specification look at Design and Make It Electronic Products p and . For quality control see p.

As part of your research you could look at commercially produced specifications in catalogues etc...

Highest marks will be given for:

  • Intended use of product (s) fully examined with relevant data identified and collected.
  • Existing products identified and fully evaluated against the needs of the intended user (s)
  • Analysis of the research leading to detailed design specification (s)  that would provide a system to ensure control over the production of the product in quantity.
