The Rugby Football Union's (RFU) performance director Conor O'Shea on Thursday urged the sport's bosses to use the enforced coronavirus break to sort out the global calendar "once and for all".
For O'Shea, Italy's coach at last year's Rugby World Cup in Japan, where Eddie Jones' England lost in the final to South Africa, it has been an extraordinary time.
"Things will never be perfect but we've got an unbelievable opportunity," he said. "All I'm seeing now, from conversations I'm having every day virtually on the phone, is a real will to try to get this right once and for all."
But he said both the northern and southern hemispheres were making contingency plans.
Officials are still looking at how to complete the 2020 tournament, which has been suspended because of the virus.
"We were investing in and will continue to invest in our high-performance pathways," he said.
