Acceptance Test-Driven Development refers to a software development methodology that emphasizes the creation of acceptance tests before the actual coding begins. This approach ensures that the software meets the specified requirements and user expectations by defining clear criteria for success. Knowledge of Acceptance Test-Driven Development is used to guide the development process, enabling teams to create features that are verifiable and aligned with stakeholder needs, ultimately improving software quality and reducing rework.

External Dependencies refer to the relationships and interactions between a project and external entities that can impact its execution and outcomes. This skill involves identifying, analyzing, and managing factors such as suppliers, regulatory requirements, and stakeholder inputs that are outside the direct control of the project team. Knowledge of External Dependencies is used to ensure that potential risks are mitigated and that project timelines and deliverables are aligned with external influences, thereby facilitating successful project completion.

Point estimation is the process of using statistical data to estimate an unknown parameter, such as an average or a proportion, by selecting a single value as the best estimate. It requires specialized skills in statistical inference, probability theory, and data analysis. Point estimation is widely used in various fields, such as economics, finance, engineering, and social sciences, to make informed decisions based on limited information. However, it has limitations and should be used with caution, as it may lead to biased or inaccurate results if the underlying assumptions are incorrect or the sample size is too small.
