Certainly. As the minister mentioned, we have seen progress with the pod model since it was launched with a pilot in December 2017, in three departments. We've been working since then with the staff at the pay centre in Miramichi and in our regional offices to expand the model as quickly as we can, with the appropriate level of staff and support to provide the leadership, the training and the coaching to allow the transition to a pod.
Essentially, Mr. Chair, a pod is a group of about 25 compensation staff, which include experienced compensation advisers, support staff who literally are taking both theoretical training and training on the job. They start off with straightforward transactions in the pod and then grow their knowledge base over time, supplemented with training. The pod is also equipped with a team lead, a data analytics specialist to help direct workload to the right people, to make sure that what comes in can be dealt with within the right time frame, the current pay period, so nothing new becomes old.
What happens with the pod, with this organizational structure, is that linkages are made back to the departments that they are serving, so direct connections with HR and with the finance groups, to allow information to flow back and forth. It allows departments to identify which priority transactions they would like the pod to work on to respond to their own particular circumstances. Some departments choose to deal with the oldest cases. Some departments choose to deal with the most complex cases, regardless of age, but that's based on their own feedback and their interaction with their staff. We work with them to grow those relationships.
At this point we are into the third wave of pod rollout this week and next. We'll now be at about 70% of pay centre staff being served by a pod, and that number will reach 100% by the end of May. What we've seen in terms of results is that, on average, even with the staggered rollout, the pods have reduced the backlog or the queue for their departments by almost 30%, whereas generally the reduction has been 25% across the entire network over the last 12 months. We are seeing the benefits of this.
Once all departments are on the pod, we will continue to see benefits as the service ratio is quite a bit smaller than is a transaction-based ratio. Fewer people can serve more people because of the structure and the knowledge sharing that happens, the skills development that happens. At the same time, we see that departments are understanding more what they can do within their own HR or finance departments to streamline processes to improve the flow of information back and forth. Essentially, the pod is dealing with an individual's file so that, as they clean things up, once a person is made whole and nothing new becomes old, they stay whole and their files remain clean.
