The ISO 20252:2019 Statement of Applicability (Clause 4.1.1) replaces the old Scope Statement from ISO 20252:2012/ISO 26362:2009. Basically the answer is YES; however, consider an 80/20% rule. If 80% of your business consists of certain services provided to your client groups, then this is the general scope of your business. Within the revised ISO 20252, subcontracted services are considered within each Annex and are included in the Statement of Applicability. The 20% of your business remaining may include specific project related work for a particular client or clients that are not your normal market research standard operating methodology. These jobs can be left out of the scope of works as long as they do not grow to represent more than approximately 20% of your business. Additionally, some market research companies provide other services such as strategic planning that do not have a direct market research function. This work does not fit within the bounds of ISO 20252:2019 and therefore should not be included in the scope of work.
