England suffered a shock 25-13 defeat against Scotland last weekend, when they struggled to cope with the home side's tactics and Jones has pointed to leadership issues all over the pitch.
"We've always known that we have to improve in our leadership," Jones said.
"That's an ongoing issue for us, and something that takes time and is not solved overnight," he said.
"It takes development, intellectual input, consultation, discussion, and we are doing all those things and moving in the right direction."
Even so, Jones says the issue is nothing new and will take them time to get right, just like it did with New Zealand.
"I always give the example of the All Blacks. It took them eight years to come up with a stable and robust leadership model to win the World Cup," he added.
"We are aiming to do that, and we've had two years together."
