whats a complex question i can pose in response to this post? Provide an implementation for one variant of the PDC (e.g., general, safety, human-services). Based on your environment (for signature assignment), what are barriers that would be faced, and how can you mitigate those proactively to align to best practices as much as possible? Make sure to identify what best practices you're able to adhere to, which you may need to deviate from, and how your plan allows you to maintain the highest validity possible in your data. The variant I am going to use would be the PDC-HS since it will be geared toward people who are responsible for providing care to others (Carr, et. al., 2013). The PDC-HS will be used to evaluate cell phone usage when during work hours, especially during sessions with clients. Implementing a performance management review using the PDC-HS, the first step is to identify the problem, in this case, it is an RBT that is distracted by cell phone usage. The second step is to use the PDC-HS to assess the cell phone usage by the RBT in question and her coworkers. Once the assessments are completed, the data can be analyzed
