Component based design and development of software is one of the most challenging issues in software engineering. In this paper, we adopt a somewhat simplified view of software components and discuss how they can be conveniently modelled in a framework that provides a modular approach to formal software development by means of stepwise refinement. In particular we take into account an observational interpretation of requirements specifications and study its impact on the definition of thedoi:10.1007/978-3-540-24626-8_5 fatcat:qstj66wjgbhnfmbxy7aepayglq
