Case Study: Applying an Agile Development Methodology to XML Schema Construction
To assure brand integrity, brands such as Coca-Cola and Proctor & Gamble, assisted by third party brand quality experts, receive, score and track the quality of their print suppliers over time. Currently this is difficult and expensive because printers use many different measurement tools and report print quality using a wide variety of proprietary formats that cannot be directly utilized by brand scoring and tracking systems. In 2015 Idealliance members launched an effort to develop a standard XML-based print quality exchange message. This specification, known as Print Quality eXchange (PQX), was developed by applying agile software development techniques to the construction of the PQX XSD. This case study highlights how agile software development principles can be applied to the construction of an XML schema.
