Question Design Input vs. Design Output - What constitutes Design Input?

Hi all, i have read so much information on design control and still have no definitive conclusion on what constitutes design input.some documents say it is only the design requirements based on user needs and others indicate that it is both the requirments and the specifications.Or should we really be saying that the design specs are a design output!!??

Re: design input vs output

What's the difference between design "requirements" and "specifications"?

Design input may take many different forms, ranging from a vague concept in someone's head, roughly sketched on a cocktail napkin to detailed specifications/requirements. In general, a thing that is the subject of design activities is expected to do something, and often what it's expected to do is described in terms of limits or ranges. A building must have x square feet of floor space, have a brick exterior and conform to local building codes, e.g.. Whatever the thing is supposed to do forms the basis of design input.

Re: design input vs output

essentially what Jim says.

here how it is defined in our procedure:
3.1. Design Inputs inlcude:
3.1.1. Functional and performance requirements as determined by the Chief Engineer and/or customer.
3.1.2. Regulatory requirements
3.1.3. A review of previous, similar designs to extract any applicable information.
Thanks to ScottK for your informative Post and/or Attachment!

Re: Design Input vs. Design Output - What constitutes Design Input?

The attached file illustrates the typical input and output of the Design process in an automotive parts manufacturing operation.

Inputs are on the left...outputs on the right. The rectangle in the center identifies the person responsible and the scope of activities to be completed.

Hope this helps.

Re: Design Input vs. Design Output - What constitutes Design Input?

Design input is the requirements of the customer, plus the requirements of the organization.
The "cookie-cutter" type of process is a good learning tool, but if you depend on that approach for a "real" customer product, then you may find that you are doing more or less then what is needed.

Re: Design Input vs. Design Output - What constitutes Design Input?

The fact that all or most of the possible ingredients have been listed doesn't mean that they will all find their way into the batter. Remember--the OP was looking for examples, and Patricia's attachment filled the bill quite nicely. Cookie cutters aside, it's always possible to do too much or too little. We have to assume sometimes that people are not robots, and are capable of making rational decisions, given the necessary information.

Re: Design Input vs. Design Output - What constitutes Design Input?

As I read the original post, it does not ask for a definition of design output:

"What constitutes Design Input?"
"What is the difference between "requirements" and "specifications"?

I must add that people who study these things will tell you that definition by example is the least useful form of definition. It is the difference between someone asking "What is a fruit?" and being told that it is the "edible reproductive body of a seed plant, especially one having a sweet pulp associated with the seed" and "things like apples, oranges, and pears." The latter is of limited value to someone who doesn't already know what a fruit is, since it enables them to recognize only apples, oranges, and pears as fruits. It tells them nothing about why these items are fruits, or how to identify other fruits as fruits. It does not contribute to an understanding what a fruit is. As I read the question, tantan seeks understanding.
