In the document the Commission lists the guidelines that the WP29 has issued (and is about to issue) on several important aspects of the Regulations. 
The Commission also list the activities that remain to be done. In particular: i) Member States must finalize “the set-up of the legal framework at national level”; ii) National DPAs must “ensure that the new independent European Data Protection Board is fully operational” (the European Data Protection Board will substitute the WP29); iii) Member States must “provide the necessary financial and human resources” to DPAs to national data protection authorities; iv) Organizations processing data must “get ready for the application of” the GDP; v) DPA must intensify their awareness-raising activities “to inform stakeholders, in particular citizens and small and medium-size businesses” of the GDPR.
The Commission also discloses its own future activities, from working with Member States in sight of May 25, 2018 (and then monitor them) to making available “online guidance” in all Eu languages, from providing financial support for wareness-raising activities to sparingly using its empowerments power. The Commission will deal with the implementation of the GDPR into EEA-Agreement (Iceland, Liechtenstein, and Norway) and will make sure GDPR concerns will be raised in the Brexit. One year after the entering into force of the GDPR the Commission will take the pulse of the implementation.
