You are talking about two different types of percentage routing here. If you use a counted method, you will get actual percentage routing, but if you use the random selection, you are getting a statistical percentage. Let's look at each:
- Counted
This method would have a value of the percentage of calls you want to move between the two carriers. if you say 30%, then you would pass 2 calls to first carrier and the 3rd to the second. If you have 50%, you would pass first call to the first and second call to the second and so on. This gets you real percentages based on actual calls received.
- Statistical
Since the ACD engine has no way of knowing how many calls you would receive in a given period, you can't really use a percentage of the unknown value to get a true percentage - that is where the random number comes in where the percentage is the random likelihood of the percentage. You would define a percentage like 30% and then generate a random number and if it is above that number, you route to carrier 1 and if below, you route to carrier 2.
As for agent utilization, you have to consider looking at number of agents and wait time for each group and then make a decision on which to pass the caller to based on the probability of the call be answered in a certain amount of time and then looking at the total calls and get some calculation to pass a percentage to each. That is a lot of guesswork and assumptions. I think the best approach to this is to have a BPO that you trust to staff correctly for your calls and not even worry about the percentage routing. If Carrier 1 is more cost-effective, then pass calls to carrier 1 until they are full and then route to carrier 2 for overflow. This all depends on the contracts you have in place to determine the best method.
