SMP VARIATIonS The larger the respondent’s practice, the more likely they are to rely on internal resources. Four out of five respondents (81%) from firms with several offices draw on internal resources, compared with 66% from firms with only one office. Participants from larger practices are also more likely to access advice from colleagues (67%) than those from practices with more than one office in one country (38%). This is as would be expected, given the wider knowledge base likely to exist within a larger practice.
