# Definitions

**Science Collaborative:** a decision analytic approach to collaboratively develop objectives related to water resources and ecosystem management in the Klamath Basin. Open and transparent decision support models will be developed for understanding and evaluating these objectives.\[PJW1] \[AV2] 

***

**Decision analysis:** Collaborative and facilitated application of multiple objective decision-making and group deliberation methods to environmental management and public policy problems. Another way to describe this is it is an organized, inclusive, and transparent approach to understanding complex problems and generating and evaluating creative alternatives. \[1][^1]

***

**Co-production and integration of knowledge:** Knowledge co-production requires collaboration between actors from different spaces and integration of diverse knowledge sources and types.\[2][^2]

***

**Science-based:** The process will use currently available science to collaboratively develop models and inform objectives.

***

**Data-driven:** The processes will be informed with the available data and necessary data\[PJW1] \[AV2] will be requested and acquired through an open and transparent process.

***

**Objectives:** This is a widely used term but has specific meaning in decision analysis as concise statements of “what matters.” \[3][^3] Identifying objectives is a discrete step within the decision analysis process.

***

**Performance measures:** In decision analysis, performance measures are specific metrics that can be used to consistently estimate and report the anticipated consequences of a management alternative with respect to a particular objective. \[4][^1]

***

**Open and transparent:** Data, models, and literature used and developed through the process will be accessible, available, and well-documented. All data will adhere to the FAIR (Findable, Accessible, Interoperable, Reusable) \[5][^4] and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) principles \[6][^5]. Additionally the process in general will be open and transparent which means that meetings will be open to all, and meeting notes and any meeting materials will be made available on the website.

***

**Sensitivity analysis:** This is a method for quantifying how uncertainty in model inputs and parameters affect the uncertainty in outputs such as the best candidate actions for attaining objectives.
