A product concept is a description of a product or service, at an early stage in the product lifecycle. [1] It is generated before any detailed design work is undertaken and takes into consideration market analysis , customer experience , product features, product cost , strategic fit , and product architecture .
Pearson's correlation coefficient is the covariance of the two variables divided by the product of their standard deviations. The form of the definition involves a "product moment", that is, the mean (the first moment about the origin) of the product of the mean-adjusted random variables; hence the modifier product-moment in the name.
Product breakdown: Recursively divide the product into components and subcomponents. Systems engineering: Ensure that the product satisfies customer needs, cost requirements, and quality demands. Value engineering: Consider alternative designs and construction techniques to reduce cost/increase profit. Value analysis: Assess the cost/quality ...
Market research is one stage of product planning and is regarded as the way to accomplish the activity though designing questions, preparing the samples, collecting data and analysing them. It provides significant insight into customers wants, needs, buying habits and behaviours and is a key tool used in the product planning process. [ 6 ]
The product design process, as expressed by Koberg and Bagnell, typically involves three main aspects: [5] Analysis; Concept; Synthesis; Depending on the kind of product being designed, the latter two sections are most often revisited (e.g. depending on how often the design needs revision, to improve it or to better fit the criteria).
The decision-matrix method, also Pugh method or Pugh concept selection, invented by Stuart Pugh, [1] is a qualitative technique used to rank the multi-dimensional options of an option set. It is frequently used in engineering for making design decisions but can also be used to rank investment options, vendor options, product options or any ...
The weighted product model (WPM) is a popular multi-criteria decision analysis (MCDA) / multi-criteria decision making (MCDM) method. It is similar to the weighted sum model (WSM) in that it produces a simple score, but has the very important advantage of overcoming the issue of 'adding apples and pears' i.e. adding together quantities measured in different units.
The Kano model offers some insight into the product attributes which are perceived to be important to customers. The purpose of the tool is to support product specification and discussion through better development of team understanding. Kano's model focuses on differentiating product features, as opposed to focusing initially on customer needs.
