Sinn Féin's leader in Northern Ireland has said next week's deadline for completing talks at Stormont should be reached.
Michelle O'Neill said Sinn Féin is committed to making the institutions work for everybody.
The recent Assembly election saw an end to the unionist majority at Stormont.
Sinn Féin now holds one seat fewer in the assembly than the Democratic Unionist Party.
Sinn Féin collapsed the power-sharing institutions after a request from Martin McGuinness for DUP leader and First Minister Arlene Foster to step aside while a botched green energy scheme was being investigated.
Almost £500m worth of taxpayers' money could be overspent on the failed Renewable Heat Incentive (RHI) scheme, which is expected to pay out more in subsidies than the green fuel costs.
A public inquiry into the matter has begun work and the judge chairing it has said it will take more than six months to report.
Ms Foster was the minister responsible when the scheme designed to promote the use of green energy was drawn up. No wrongdoing is suggested.
Speaking on RTÉ’s Morning Ireland, Ms O'Neill said the institutions could be up and working again if everyone was committed to genuine power sharing.
She said Sinn Féin wanted to deliver public services but everyone needed to step up and play their part.
If the parties fail to form a ministerial executive, NI Secretary of State James Brokenshire may call another election.
