SRU chairman David Mackay and chief executive Phil Anderton will warn that Scottish rugby faces a slow death unless their four-year plan is adopted.
The pair propose a regionalisation of the national league structure beneath the top three Premiership divisions.
They also propose franchising out the three professional sides.
Mackay and Anderton's proposals follow a consultation with those involved in the sport around the country.
They fear that Scotland faces slipping further down the world rankings as participation levels have fallen to 18th in the world.
SRU chairman David Mackay believes the possible changes in structure to the game across the country can benefit Scotland coach Matt Williams' plans.
He said: "The review has been thorough and conducted with absolute honesty and transparency.
"Scottish Rugby is not just a recurring loop of failure. There are positives but there are also serious problems which have to be addressed urgently. Change is not an option. It is the only choice."
The plan will cover the next four years with targets including a Six Nations title, a Celtic League win by one of the three professional clubs - Edinburgh, Glasgow or Borders - and a Heineken Cup quarter-final every year by 2008.
SRU chief executive Phil Anderton is also keen to see the governing body trading profitably every year.
He said: "We need to plan for success, not just expect it to happen.
"If you don't know where you're going you won't know how to get there.
"We need to aim high and be radical, planning where we want to get to, not where we can get to.
"Therefore, Scottish Rugby's long-term vision is to win cross-border competitions in which our representative sides compete and to grow rugby faster than any other sport in Scotland with increased participation.
"We all want Scotland to be a successful rugby nation where we are proud of the performances of our representative teams and rugby is at the heart of our communities.
"The route we are currently navigating is not going to get us there consistently so we need to change course.
"To deliver all we want to achieve, we are going to have to make some hard choices and discard ideas that may have been cherished in the past in order to become more effective and efficient as both the governing body of rugby in Scotland and a business."
