The approval process is completed when the document, after being submitted, has been sequentially reviewed by the submitter's senior officers and then approved by the final approver. In some cases, the cosigners' approval process is added in the middle of the sequential process. For example, when cooperation or approval from other departments is needed, their approval or rejection might affect the final decision-making process. The Group Approval supports this cosigners' approval process via parallel approval options. There are two types of parallel approval options, Cooperative and Co-Approval, allowing you to define how cosigners' decisions will affect differently the next steps in the approval process
Cooperative When there are two or more cosigners in a cooperative relationship, the document is considered approved unless all of the cosigners have rejected it. In other words, if any of the cosigners approves, the document in that particular step is considered approved. If all of the cosigners have chosen to reject the document, the document approval process ends as rejected, returning the document back to the submitter. In any case, every cosigner must sign the document, either approving it or rejecting it, before the process can move on to the next step. Therefore, even a single cosigner delaying signing could delay the entire approval process. This option is useful when the opinions from different stakeholders must be considered because it lets the next approvers view the opinions of a number of cosigners as they are whether they have approved or rejected the document.
Co-Approval When there are two or more cosigners in a co-approval relationship, the document is considered approved only if it is approved by all of them. In other words, if even a single cosigner rejects, the current approval step is considered rejected. However, as in the cooperative relationship, every cosigner must make his or her decision before the document can be returned to the submitter. While this option can hear opinions from many cosigners, it can also delay the entire approval process when even a single cosigner delays making a decision.
