Slice aims to keep roles and user privileges simple. Simple roles help users better understand their responsibility on a project, and keeps users from being surprised if they cannot interact with something on the project.
Roles are divided into two categories, editors and viewers. Simply, editors can make any change they wish on the project, and viewers can view anything on the project.
The amount of project information these roles can edit or view can be further limited by the following items, site versus project membership and the blinding status of the assigned role.
As mentioned in the section on project sites 1 a new member can be either assigned to a specific site on the project, or can be allowed to see the project as a whole. Slice calls these roles site members and project members. Project members can see all subjects and data across all sites on a project, while a site member will limited to the subjects and data specific to the member's site.
Note: A user can be invited to multiple sites.
When the blinding module 2 is enabled, a user can be assigned a role that is flagged as "Blinded". This will prevent the user from seeing any subject information that could potentially unblind the user.
For projects that have the blinding module disabled, the roles matrix looks as follows.
|Project editor.||Can do anything.|
|Project viewer.||Can see anything.|
|Site editor.||Can edit site subjects.|
|Site viewer.||Can view site subjects and reports.|
For projects that have the blinding module enabled, the role matrix expands and looks as follows.
|Unblinded project editor.||Can do anything.|
|Unblinded project viewer.||Can see anything.|
|Blinded project editor.||Can edit anything, except for randomizations and AEs.|
|Blinded project viewer.||Can see anything, except for randomizations and AEs.|
|Unblinded site editor.||Can edit site subjects.|
|Unblinded site viewer.||Can view site subjects and reports.|
|Blinded site editor.||Can edit site subjects, but not see randomizations or AEs.|
|Blinded site viewer.||Can view site subjects and reports, but not randomizations or AEs.|
Project editors can modify project settings, invite new collaborators, create subjects, enter sheets, randomize subjects, report adverse events, view reports, generate data exports.
Project viewers can view subjects, including subject sheets, randomization status, adverse events, and subject timelines. Project viewers can also comment on subject sheets, view reports, and generate data exports.
An unblinded member has no restrictions based on randomizations or adverse events.
A blinded member cannot see existing randomizations, or randomize a subject to a treatment arm. The blinded member can also not see data sheets for designs or events that are flagged as unblinded-only. These designs or events may include information that would unblind the blinded member. A blinded member can also not report or view adverse events, as adverse events have a high likelyhood of including information that could unblind the blinded member.
