Encapsulation — private instance variable a… Necessary to ensure the quality of the software. They do not compete with each other. This article summarizes some of the core principles, best practices, and my common sense for governing the Software Development Life Cycle. However it is possible, and necessary, to compare the Design products with the Decide products to see if what is wanted has been included. Implementing a SDLC is all about quality, reducing costs and saving time. I propose the “4D” model as a generic model for understanding the larger issues. A brief overview of the Software Development Life Cycle and a few key principles of software testing. View Tutorial Week 1 SDLC Conceps and Principals.pptx from CS 1 at Asia Pacific University of Technology and Innovation.
