She explained: "I hope this will enable our Parliament to be more responsive and agile in responding to the major issues of the day and holding the Government to account."
With regard to committees, Mrs Marwick said: "Further initiatives to reform our processes clearly remain, however.
"More than 12 years into devolution, it is crucial that the culture and working practices of the Parliament evolve and keep pace with new developments as we strive to be the responsive, relevant body that the public expects."
The Presiding Officer wants all MSPs to consider how the work of committees at the Parliament could be improved.
She is also working with committee conveners on "ways to enable committees to be more reactive and topical".
