Abstract: Numerous elements influence the quality of software systems. One of these elements is the use of design patterns. This paper examines the influence of design patterns on quality requirements in particular maintainability. Improving the maintainability of software systems provides a higher opportunity for recovery because maintenance costs can use 60-80% of the complete budget of proprietorship of software systems. In addition, if the maintainability of the software system is poor, the destruction of the product will increase and the system will rapidly lose its importance to stakeholders. In this context, we propose a pattern guided approach to improve the maintainability of software products. Maintainability is measured by certain factors. We focus in this article on the observer and the façade design patterns to illustrate our work.

Keywords: maintainability; design patterns; tactics; metrics.
