Defining a non functional requirement to ensure the system is scalable.

**Application Name:OpenMRS **Version Number:1.11

**Question: I work for Jembi Health Systems and we are assisting MSH and the MoH in Rwanda to roll out a national implementation of OpenMRS.

I was wondering if anyone can assist me in defining the non functional requirements with regards to ensuring the system is scalable i.e. for a national implementation, how many Patient Records should the system be capably of storing with how many visits per Patient?

If anyone can provide a different approach to defining this requirement and ensuring the system is scalable, I would really appreciate it.
