IMS Framework validation

My final year research thesis topic "development of integrated management system for testing and calibration laboratories". I have developed the IMS Manual, conforms with the requirements of (ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, ISO/IEC 17025:2017 and AS 9100D: 2016). I also developed the IMS Framework as per the IMS Manual.
Now I want to validate that framework. I want you to guide me how to validate the IMS Framework?
I'm also going to implement this IMS manual in an organization.

Answer:
Any plans must be updated when they start contacting reality. Your IMS Framework should be viewed as an initial approach based on your experience and learning. Now you should use your opportunity to implement it in an organization as a way of validating your work and fine tuning it.
Start by the end: what is the organization’s actual performance and what improvements do you want or expect to see after a certain time frame. Implement your IMS Framework and c heck evolution against performance measures and perform internal audits to check conformity and improve the IMS Framework. Effectiveness is the most important outcome.
