Quigley Scientific: Solutions for Customization and Product Excellence

This year Quigley Scientific celebrates its twenty-second year of business as a consulting firm. We have provided mechanical engineering design, and advanced analysis as critical and important issues for our clients.

We have taken a survey of the typical questions raised during interactions with our clients. Across a variety of projects, the following concerns were found in various combinations for our projects. These issues, in some cases, were the main reasons we were invited to discuss solutions. In other cases, the themes emerged during the progress of the project. One difficulty when first coming on board for a client is to begin the investigation of the main issue with an open minded view of what other conditions could be present which affect the product quality.

To begin to access the expertise of Quigley Scientific, this document will act as a starting point or working document for further discussion with your company and possibly assist in preparation of a Request for Quote.
