4. The document outlines several "laws" and myths regarding software evolution, management, customers, and practitioners
Software Quality Attributes
The quality of software systems may be expressed as a collection of Software Quality Attributes. When the system requirements are defined, it is essential also to define what is expected regarding these quality attributes, since these expectations will guide the planning of the system architecture and design.
Software quality attributes may be classified into two main categories: static and dynamic. Static quality attributes are the ones that reflect the system’s structure and organization. Examples of static attributes are coupling, cohesion, complexity, maintainability and extensibility. Dynamic attributes are the ones that reflect the behavior of the system during its execution. Examples of dynamic attributes are memory usage, latency, throughput, scalability, robustness and fault-tolerance.
Following the definitions of expectations regarding the quality attributes, it is essential to devise ways to measure them and verify that the implemented system satisfies the requirements. Some static attributes may be measured through static code analysis tools, while others require effective design and code reviews. The measuring and verification of dynamic attributes requires the usage of special non-functional testing tools such as profilers and simulators.
In this talk I will discuss the main Software Quality attributes, both static and dynamic, examples of requirements, and practical guidelines on how to measure and verify these attributes.

Introduction to Software Development
Software development has shifted focus from efficiency to productivity, reusability, and user-friendliness. Object-oriented programming (OOP) models objects that contain data and methods. Key OOP concepts include inheritance, where subclasses extend and modify superclass features. An integrated development environment (IDE) combines tools like editors, compilers, linkers, and debuggers. Java uses a hybrid approach of compiling to bytecode, then interpreting for platform independence. Console applications use text input/output. Graphical user interface (GUI) applications use menus and buttons. Applets run in web browsers.

What is the Objective of Software Testing?
Software testing is the process of evaluating the functionality of a software application with an intent to find whether the developed software met the specified requirements and to identify defects to ensure that the product is free from errors. It involves the execution of software/system components using manual or automated tools to evaluate one or more properties of interest. The necessity of software testing arises from the critical role that software plays in our lives and the potential harm that software defects can cause to the economy, security, and well-being of users.
