The choice of software development model depends on product and project characteristics1. A software development model is a framework that defines the activities, tasks, roles, and deliverables of a software project1. There are various software development models, such as waterfall, V-model, iterative, incremental, agile, etc1. The choice of software development model depends on product and project characteristics, such as size, complexity, scope, requirements, quality attributes, risks, resources, schedule, budget, etc1. Different software development models have different advantages and disadvantages for different types of products and projects1. Therefore, the choice of software development model depends on product and project characteristics.

Boundary Value Analysis is a black-box testing technique that is used to test the boundaries or limits of input or output values for a given system or component. Boundary Value Analysis helps to identify errors at the edges of an input or output domain. For example, in a system designed to work out the employee tax to be paid, there are four boundaries for the salary input: $4,000 (lower boundary for tax free), $5,500 (upper boundary for tax free and lower boundary for 10% tax), $34,000 (upper boundary for 10% tax and lower boundary for 22% tax), and any value above $34,000 (upper boundary for 22% tax and lower boundary for 40% tax). A valid Boundary Value Analysis test case would test one value below, on, and above each boundary. For example, $33,501 is a valid test case because it is one value above the boundary of $34,000. A detailed explanation of Boundary Value Analysis can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 38-41.

Component testing is a part of the V-Model, which is a development life cycle model that shows the relationship between each phase of development and its corresponding phase of testing. In this model, each level of testing (unit testing, integration testing, system testing, acceptance testing) has a corresponding level of development (component design, component integration, system design, requirements analysis). Component testing is the process of testing individual components or units of software in isolation from other components or systems. Component testing verifies that the components meet their functional and non-functional requirements and work as expected in their intended environment. Component testing is usually done by developers who have access to the component design and code specifications. You can find more information about component testing and the V-Model in Software Testing Foundations: A Study Guide for the Certified Tester Exam, Chapter 22.
