The first step to Implementing BS 10012 would be to carry out a Gap Analysis to identify where the gaps are in your Personal Information Management. Evaluate the results and formulate a plan to put the correct policies and procedures in place to be compliant. This evaluation will also highlight any potential existing risks with your personal information management, which can then be addressed as you create your management system.
Unless you are familiar with BS 10012 requirements, we suggest seeking out guidance or support with the process of establishing a management system. Blackmores also offer assistance with BS 10012, so feel free to contact us for more information.
