Tandy’s first game in charge will be the autumn opener against Argentina in Cardiff on Sunday, 9 November.
By then the Welsh Rugby Union hope to have outlined their plans for the professional game with the possibility of cutting from the current four regions, Dragons, Cardiff, Ospreys and Scarlets down to three or maybe two teams.
“We’ve got to build something that suits us, not follow anyone else,” said Tandy, who was part of a Scottish system that features the duo of Glasgow and Edinburgh.
“There are challenges in any programme but we have to build something that suits us and I am coming in with my eyes wide open.
“Ultimately, we want Wales to be back to where we belong and where we want to be. There is a lot of work that goes in behind that.
“Everyone at the [Welsh Rugby] Union and at the clubs wants Wales to be really competitive. How that looks, I am not quite sure yet, but I know where the intention is to be.
“I know it’s hard because emotion plays a massive part in the game, and is one of our strengths.
“But there has to be a focus of where we want go to, how we can align ourselves better and create something that everyone can really buy into for us to be competitive, not just in the national game but right across Wales.”
