@sharonvarghese probably it would be a good idea to start creating ERD based on the model Burke has shared. This would also help you in understanding the missing components better. Also to get better understanding of project its always better to get end user perspective. Following are very good articles about how to design a cohort. > **[Introduction to study designs - intervention studies and randomised...](https://www.healthknowledge.org.uk/e-learning/epidemiology/practitioners/introduction-study-design-is-rct)** > > Introduction Learning objectives: You will learn about interventional study design and its strengths and weaknesses.

We can also work more to add a randomizer component in our module later on. Keeping provision for this would be a good idea. --- _[View the full topic](https://talk.openmrs.org/t/cohort-module-discussion/1627)._
