Build

Question 25

Code developed in build phase is made error free. Also, in addition to the corrections to the code, the code is modified according to the user's requirements

Answer 25

Fix

Question 26

Expected Results of Build and Fix

Answer 26

* initial application not that good, usually it is not maintainable. 🤒 * a lot of maintenance is done 🏥 * user checks the functions, modify/delete 🔎 * user checks until satisfaction (can be used productively) 👀

Maintenance and Modification of the system is done by

Answer 28

Programmer/Developer

Question 29

A process of software development where requirements are broken down into multiple standalone modules of software development cycle. Done in steps from analysis, design, implementation, testing/verification and maintenance.

Answer 29

Incremental Model

Question 30

Characteristics of Incremental Module

Answer 30

* ⛓️‍💥system dev break down to mini dev projects * 🌓partial systems to final * ⚠️high priority tackled first * 🧊once requirement is developed, increment frozen
