Quality evaluation methods are ways of assessing the worth of materials, processes and products, among other things. They are applicable in many fields of human endeavor, especially manufacturing. The standard of goods produced in factories, for example, is often maintained with quality evaluation methods. These may be triggered by human or mechanized intervention. Quality evaluation methods are vital to any business wanting to discover how well it is performing.

Web-site Quality Evaluation Method

As described by computer scientist Luis Olsina Santos, the Web-site Quality Evaluation Method is a methodology to assess and compare the comparative quality of websites. Santos utilizes the Logic Scoring of Preference model in his work, whereby such characteristics as efficiency, functionality, maintainability, portability reliability and usability of a website are given scores. After score correlation among the judging panel, Santos is able to publish a preference list relating to measurable attributes.

Data Quality Evaluation Methods

International SEMATECH Manufacturing Initiative specializes in methods for addressing data quality issues for e-Manufacturing processes. E-manufacturing revolves around use of the Internet and e-business technologies. The company samples data provided by manufacturing equipment and applies both qualitative and quantitative evaluations thereof. Qualitative evaluation is an assessment process to discover how well something was done. Quantitative evaluation is an assessment process to discover how much was done.

Inspection Conveyor with Reject System

Human intervention to remove and reject items from conveyor belt systems, either raw materials on their way to manufacturing processes or finished articles on their way to packing, is expensive and can mean very repetitive activity for the operatives. An inspection conveyor with reject system is an automated system to remove reject items from manufacturing processes. This ensures that unsatisfactory quality raw materials do not progress any further and that finished articles are of consistently high quality.


Informal quality evaluation methods include team meetings, where every member of the team is required to describe the current status of their projects. On a more formal level, some companies employ consultants to assess specific working methods and suggest more efficient business processes. When this is a full scale, organizational level analysis and redesign of work flows and processes, this is often referred to as business process re-engineering.
