 A parametric estimate is an estimate that uses a mathematical formula or model to calculate the time, cost, or resources required for a project or activity based on historical data and known variables. In this scenario, the 25 workstations per hour represents a parametric estimate of the productivity of the project team, which can be used to determine the total duration and cost of the installation. A parametric estimate is usually more accurate and reliable than other estimation techniques, such as expert judgment or analogy, as it is based on objective and quantifiable data. References:

 A requirements package is a document that contains a set of requirements that have been analyzed, refined, and formatted to meet the needs of various stakeholders. The primary goal of developing a requirements package is to communicate the requirements effectively and efficiently to the intended audience. A requirements package may include different levels of detail, different types of requirements, different formats and structures, and different supporting information depending on the stakeholder’s needs and preferences. A requirements package should be clear, concise, consistent, complete, correct, and testable. References:

 A test plan is a document that describes the scope, objectives, strategy, and activities of testing a software product or system. A test plan is mandatory in most software development projects because it ensures that the software meets the quality standards and requirements of the stakeholders. A test plan also helps to identify and mitigate the risks, defects, and issues that may affect the software functionality, performance, usability, and security. A test plan is different from a communication management plan, which is a document that describes how the project information will be communicated to the stakeholders. A test plan is also different from a disaster recovery plan, which is a document that describes how the project will resume its operations in the event of a disaster or emergency. A test plan is not a procurement plan, which is a document that describes how the project will acquire the goods and services needed from external sources. References:
