What are the differences between sequential and parallel approval?


In January 2018, Procore began rolling out a new submittal workflow model to provide your users with more flexibility when setting the approval path for a submittal. This new model prevents project users with 'Admin' level permission on the Submittals tool from having to specifically configure the tool to use sequential approval or parallel approval. The new submittal workflow table will be rolled out to all Procore accounts and will allow your users to create and edit submittals that use either sequential, parallel, or a combination of both approval models.

Sequential Approval

With sequential approval, all designated persons assigned as approvers by the creator (or the submittal manager) must submit their responses (see What are the default submittal responses in Procore?) in the order designated by the submittal workflow. Sequential approval is the default setting in Procore. 


Let's assume a subcontractor creates a submittal and defines a list of approvers in the Submittal Workflow area. First, the project manager must approve the submittal. After the project manager approves the submittal, it must then approved by a project engineer. After it is approved by the project engineer, it must then be approved by the architect. This workflow requires approvals to be submitted in sequential order.

Parallel Approval

With parallel approval, all of the designated approvers can submit their responses concurrently. To enable the parallel approval workflow, your company's Procore Admin must submit a request to your Procore point of contact or to support@procore.com. A Procore point of contact can then enable the feature in Procore for your company's account. 


Let's assume a subcontractor creates a submittal and then sends it to a project manager for editing. The project manager then updates the submittal as needed, and then sends it to the entire design team for review. The approvers can then review and submit their individual responses at the same time and in any order.
