Although 71 percent of non-PMO project staff surveyed in Singapore said the PMOs' involvement improved the effectiveness and availability of training, the situation is different for other parts of the world.

About 82 per cent of organisations worldwide said they have a PMO and more than half of these do not measure PMO effectiveness.

Report shows that PMOs have matured, and today enterprises are questioning the value of these offices.

Also, organisations want to know PMOs' ability to measure effectiveness and their role in growing PM capabilities through effective training.

"The large majority of organisations who have PMOs indicate that they understand the advantages that PMOs can offer," said J. LeRoy Ward, PMP, PgMP, executive vice president, product strategy and management, ESI International. "The results of ESI's global survey indicate numerous areas where PMOs currently need to step up their game to demonstrate the impact of those advantages, including measurement, effect on career progression and their strategic role in the organisation."
