User-Defined Variable

Definition

A user-defined variable is a numeric value specified by a user to drive estimate quantities in lieu of a modeled value.

Purpose

User-defined variables allow for customization and flexibility in estimating and modeling processes. By inputting specific values, users can tailor calculations and projections to better fit their particular needs and scenarios.

Examples of Use

• Construction Estimating: Using user-defined variables to input unique cost factors or quantities that differ from standard models.
• Data Analysis: Specifying user-defined variables to customize data visualizations and reports according to specific criteria.
• Simulation Modeling: Adjusting user-defined variables in simulations to explore different scenarios and outcomes.

Related Terms

• Parameter: A value that defines a system or sets the conditions of an operation.
• Variable: An element, feature, or factor that is liable to vary or change.
• Customization: The action of modifying something to suit a particular individual or task.

Notes

User-defined variables are essential for adapting generic models to specific situations. They provide users with control over their data and calculations, enhancing the accuracy and relevance of their estimates and analyses.
