Survey modifications

Number	Dimension	Type of modification	Impact on model
1	Strategy and policy	ML3Q1 was interchanged with ML4Q2 based on perceived complexity. In its new position ML4Q2 was reworded following recommendations of the respondents	Better fit of model and ordered complexity
2	Organization and processes	ML5Q2 was interchanged with ML3Q2 based on perceived complexity of the statement	Better fit of model and ordered complexity
3	Organization and processes	Statement ML4Q2 was reworded to fit the complexity of maturity level 4 based on comments of one of the respondents	Statement ML4Q2 better fits maturity level 4 and follows increased complexity
4	Information technology	Statement ML5Q1 was reworded to fit the complexity of maturity level 5	Statement ML5Q1 better fits maturity level 4 and follows increased complexity
5	People and culture	Statement ML5Q1 was reworded to fit the complexity of maturity level 5	Statement ML5Q1 better fits maturity level 5 and follows increased complexity
6	PACS performance	Answer categories of performance metric C2 (see “Appendix”) have been rescaled	Results in better distribution of scores
