Principles of Software Engineering

Notes Matrices: The process of optimizing the reliability of software through a program that emphasizes
software error prevention, fault detection and removal, and the use of measurements to maximize
reliability in light of project constraints such as resources, schedule and performance.
Matrices Size: Size of Matrices has verification complexity metric available that could guide the
user in selection of transformations, and so we present a hybrid of metrics to the use the SPARK
Examiner, and our own analyzer.
Refactoring: A change made to the internal structure of software to make it easier to understand
and cheaper to modify without changing its observable behaviour.
Verification: It is the act of reviewing, inspecting or testing, in order to establish and document
that a product, service or system meets regulatory or technical standards.
1. Prepare a structure to refactoring a program.
2. Create a flow chart for the verification process in refactoring.
