Typically, first gen outsourcing deals / legacy environments have calls and emails as predominant contact channel and proportion of calls and emails could potentially exceed 80-90% of the contacts. However, as service providers rationalize the workflow and implement chat bot and other tools, proportion of calls and emails gets reduced in favour of other channels e.g., chat and web with lower cost to serve. In an end state, service providers may have 60-75% of contact volume by web and chat and remaining 25%-40% by phone calls and emails.
