If agents become the main point of interaction, the applications underneath them will continue to perform essential functions. Accounting software will maintain financial records, the CRM will organise customer relationships, and project management systems will hold tasks, responsibilities and deadlines.
What changes is how often an employee needs to open each application directly.
We can imagine a working day in which someone reviews priorities through an assistant, asks it to investigate an issue and approves a proposed action without visiting every system involved. Some tasks may begin through a conversation, while others start automatically when an agreed condition is met.
A renewal process, for example, could bring together contract dates, current services, account activity and outstanding issues before presenting a proposed renewal for review. The person responsible would still make the commercial decision, but much of the preparation could happen in the background.
This would also change what businesses value when choosing software. The interface would remain relevant, but buyers would have stronger reasons to examine the capabilities underneath it: whether information can be retrieved reliably, whether actions can be performed through integrations, and whether access can be restricted appropriately.
A feature that is available only through a sequence of manual screens may be much harder to incorporate into an agent-led process.
