+# Katib 2019 Roadmap
+
+This document provides a high level view of where Katib will grow in 2019. These objectives are based on Katib's Critical User Journey (CUJ),
+which can be found [here](https://bit.ly/2QNKMwt).
+
+The original Katib design document can be found [here](https://docs.google.com/document/d/1ZEKhou4z1utFTOgjzhSsnvysJFNEJmygllgDCBnYvm8/edit#heading=h.7fzqir88ovr).
+
+# Katib 1.0 Readiness
+
+* Stabilize APIs for StudyJobs
+	* Beta by end of Q2, 1.0 by end of Q4
+	* Formalize naming conventions (we use different names like katib vs vizier in different places)
+	* Refactor studyjob field names [#351](https://github.com/kubeflow/katib/issues/351)
+	* Rename fields so their names are more meaningful (e.g. requestCount vs requestNumber) [#161](https://github.com/kubeflow/katib/issues/161)
+* Fully integrate katib with existing E2E examples:
+	* Xgboost
+	* Mnist
+	* GitHub issue summarization
+* Publish API documentation, best practices, tutorials
+* [Issues list](https://github.com/kubeflow/katib/issues)
+* [Issues for 0.5.0 release](https://github.com/kubeflow/katib/labels/area%2F0.5.0)
+
+
+# Enhance HP Tuning Experience
+
+The objectives here are organized around the three stages defined in the CUJ:
+
+## 1. Defining Model and Parameters
+
+Integration with KF distributed training components
+* TFJob
+* PyTorch
+* Allow Katib to support other operator types generically [#341](https://github.com/kubeflow/katib/issues/341)
+
+## 2. Configuring a Study
+* Streamlining the StudyJob schema - providing simpler ways to write worker specs and metric collector specs.
+* Expose more information in StudyJob status fields
+	* List all job conditions with details [#344](https://github.com/kubeflow/katib/issues/344)
+	* Returning study metadata such as number of trials and best hyperparameter values so far [#356](https://github.com/kubeflow/katib/issues/356)
+* Integration with Jupyter notebooks and Fairing [#355](https://github.com/kubeflow/katib/issues/355)
+	* Allow users to start with an existing model from a notebook and do HP tuning with minimal code changes
+* Allowing a StudyJob to be resumed with additional trials [#346](https://github.com/kubeflow/katib/issues/346)
+* Generating StudyJob configurations and launching StudyJobs through UI
+* Supporting additional suggestion algorithms [#15](https://github.com/kubeflow/katib/issues/15)
+* Support for StudyJob deployment in a different namespace [#343](https://github.com/kubeflow/katib/issues/343)
+
+
+## 3. Tracking Model Performance
+* Enhance metrics collection
+	* May need to revisit the design - use a push model instead of pull model?
+* UI enhancements: allowing data scientists to visualize results easier
+* Support for persistent model and metadata storage
+	* Ideally users should be able to export and reuse trained models from a common storage
+
+
+# Other Features
+
+Designs are pending for the following new features:
+* Multi-Tenancy Support
+* [NAS](https://docs.google.com/document/d/1qGWy-C5XSQmh82XYoMcJ_JWLHwmyvdMRjCkFMfkO0vE/edit)
+* Batch scheduling
+* [Integration with Pipelines](https://github.com/kubeflow/katib/issues/331)
+* Early stopping feature
+
+# Test and Release Infrastructure
+
+* Improve e2e test coverage
+* Improve test harness
+* Enhance release process; adding automation (see https://bit.ly/2F7o4gM)
