For instance, Vanguard has an employee form in which an employee acknowledges various obligations to honor the privacy of protected health information. Computer security models are foremost about mapping people to information. The security mechanism view at the most primitive level is below the level of workflow management. For instance, encryption algorithms are about machines and algorithms and not about workflow. However, still within the mechanism realm are matters such as Public-Key Infrastructure.
Different organizations formalize workflow management to different degrees.
The Connecticut Hospital Association Public-Key Infrastructure demonstrates certificate management based on roles and responsibilities. DHHS has requested that professional societies, state health departments, and others try to contribute to the body of shared models. Each organization type will have particular needs, and an organization should build on the experiences of similar organizations. The challenges faced by the healthcare industry involve both defining and changing workflow. The 'changing' part is of course the hardest part.
