Unit groups give you the ability to group your units. For example, in Text, Audio or Video projects you may want to break up longer files into smaller segments, but still keep the segments in sequence and make sure one person works on them, so they can retain the context.
To create unit groups, add a column called "_UNIT_GROUP" and a column called "segment_no" to your upload file and group all the units you wish to keep together using numbering such as the example below. Quality Flow projects will detect the formatting in this upload file and will create three unit groups with four segments each.
After the file is uploaded a Unit Groups tab will be visible on the DATASET page.
And you will be able to perform certain Actions from the User Group table.
Sending Data to Jobs
When you send data to Jobs in "Segmented" projects you will be prompted whether to send all units (this will help make sure you don't accidentally leave any units out of your selection). Or else you can choose to send a particular unit but also a certain number of units before or after that unit, for context, see second screenshot below.
You must also specify in the settings for the destination Job that you want contributors to receive the groupings you have designated as a single task, see below.
The choice to only send some surrounding context may be useful later in a Project when you are doing revisions, for example.
Prices & Rows Settings
Here is where you can decide whether your Job should "Retain Grouping" or not. "Retain Grouping" means that groups will always be kept together in the job. Contributors will receive whole groups and will need to complete the entire group as a task. Later in a Project you may wish to create other Jobs that do not require to keep whole groups together and you can choose "Ignore Grouping" for these jobs.
