Measuring Architecture Principles and Their Sets in Practice: Creating an Architecture Principle Measurement Instrument Challenged in a Case Study at the Dutch Tax Agency

Although architecture principles are important in the implementation of information systems requirements, empirical evidence of the effect of architecture principles is lacking. To find this empirical evidence, we need an instrument to measure architecture principles in the first place. This paper is the result of creating an architecture principle measurement instrument challenged in a case study. We describe both the measurement instrument and the related measurement method, including the test in a real-life case. Based on the outcome we extended the instrument with extra architecture principles characteristics and attributes. We also made some improvements on the measurement method as well.
