+name: Design Proposal
+about: I have a significant change I would like to propose and discuss before starting
+labels: "Status: Untriaged"
+---
+
+### When a Change Needs a Design Proposal
+
+A design proposal should be opened any time a change meets one of the following qualifications:
+
+- Significantly changes the user experience of a project in a way that impacts users.
+- Significantly changes the underlying architecture of the project in a way that impacts other developers.
+- Changes the development or testing process of the project such as a change of CI systems or test frameworks.
+
+### Why We Use This Process
+
+- Allows all interested parties (including any community member) to discuss large impact changes to a project.
+- Serves as a durable paper trail for discussions regarding project architecture.
+- Forces design discussions to occur before PRs are created.
+- Reduces PR refactoring and rejected PRs.
+

+
+<!---  Proposal description and rationale.  -->
+
+## Motivation
+
+<!---
+    As a <<user_profile>>,
+    I want to <<functionality>>,
+    so that <<benefit>>.

+
+## Specification
+
+<!---  A detailed description of the planned implementation. -->
