Assignments and job ownership

Execution owner versus validation reviewer

These are different assignments with different purposes.

Assignment	Who it is for	What it enables
Execution owner	Technician for sample analysis, trainer for training, consultant for consultation	Starting the work and recording the operational delivery steps.
Validation reviewer	Reviewer	Reviewing a submitted job and approving it or requesting changes.

A reviewer may be assigned before work starts. This is intentional: it makes the later validation handoff explicit without making the reviewer the delivery owner.

Starting work

Before you select Start Work, confirm that the job has reached its required preparation step:

Job type	What must happen first
Sample analysis	Payment is confirmed, you are assigned, next instructions have been sent, and samples are recorded as received.
Training	Payment is confirmed, you are assigned, and next instructions have been sent.
Consultation	Payment is confirmed, you are assigned, and next instructions have been sent.

After Start Work, the job moves to In Progress. For sample analysis, receiving physical samples does not itself start laboratory work; it records custody and creates the initial sample records.

When you can see work but cannot act

This is usually expected in one of these situations:

you are in the correct service group but are not the assigned execution owner
the job is assigned to someone else
the job has not reached the required lifecycle stage
a predecessor step is incomplete, such as physical receipt or sent instructions
your current workspace is client rather than staff

Ask an administrator to correct the assignment or service-group scope. Do not use another person’s account to bypass an assignment restriction.

Handover and rework

When a reviewer requests changes, the job returns to the delivery owner. Resume work, correct the issue, update the relevant evidence or final deliverable, then submit the job again for review.
