+#### Development description
+
+_Describe the goal and the methodology._  
+_Add reference documents or publications if relevant._
+
+#### Code implementation
+
+_Describe flow chart of the changes in the code._  
+_List the Fortran modules and subroutines to be created/edited/deleted._  
+_Detailed list of new variables to be defined (including namelists), give for each the chosen name and description wrt coding rules._
+
+#### Documentation updates
+
+_Using previous parts, define the main changes to be done in the ~doc (manuals, guide, web pages, ...)._

+#### Tests
+
+Once the development is done, the PI should complete the tests section below and after ask the reviewers to start their review.  
+This part should contain the detailed results of ~SETTE tests (restartability and reproducibility for each of the reference configuration) and detailed results of restartability and reproducibility when the option is activated on specified configurations used for this test.
+
+**Regular checks**
+
+- [ ] Can this change be shown to produce expected impact (option activated)?
+- [ ] Can this change be shown to have a null impact (option not activated)?
+- [ ] Results of the required bit comparability tests been run: are there no differences when activating the development?
+- [ ] If some differences appear, is reason for the change valid/understood?
+- [ ] If some differences appear, is the impact as expected on model configurations?
+- [ ] Is this change expected to preserve all diagnostics?  
+  - [ ] If no, is reason for the change valid/understood?
+- [ ] Are there significant changes in run time/memory?
+
+#### Review
+
+A successful review is needed to schedule the merge of this development into the future NEMO release during next Merge Party (usually in November).
+
+**Assessments**
+
+- [ ] Is the proposed methodology now implemented?
+- [ ] Are the code changes in agreement with the flowchart defined at preview step?
+- [ ] Are the code changes in agreement with list of routines and variables as proposed at preview step?  
+  - [ ] If, not, are the discrepancies acceptable?
+- [ ] Is the in-line documentation accurate and sufficient?
+- [ ] Do the code changes comply with NEMO coding standards?
+- [ ] Is the development documented with sufficient details for others to understand the impact of the change?
+- [ ] Is the project ~doc (manual, guide, web, ...) now updated or completed following the proposed summary in preview section?
