Construction incorporates a coding and testing cycle in which source code for a component is generated and tested to uncover errors. Integration combines individual components and involves a series of tests that focus on overall function and local interfacing issues.
Coding principles define generic actions that should occur before code is written, while it is being created, and after it has been completed. Although there are many testing principles, only one is dominant : testing is a process of executing a program with the intent of finding an error.
During evolutionary software development, deployment happens for each software increment that is presented to the customer. Key principles for delivery consider managing customer expectations and providing the customer with appropriate support information for the software. Support demands advance preparations. Feedback allows the customer to suggest changes that have business value and provide the developer with input for the next iterative software engineering cycle.
