I am quite sure that most of the 20 elements do apply.
Management needs to review the system; Contracts with customers need to be established and reviewed; Documentation and Data needs to be controlled; You purchase the services of the contractors and consultants, and any product used for the outcome of the service quality you provide; Identification and Traceability of the service (tracking contractors, consultants and their projects; the service processes, outlining what is indicated in the standard;.
4.10 could be addressed in a number of ways, for instance: inspection and verification of the consultants and contractors (how do you determine the criteria for using a contractor or consultant, verifying their references, application, portfolios,etc.)Keep in mind this element ties in with 4.6.
Element 4.10 can be tied in with Test Status, Verification Status, etc. Nonconformance for service problems requiring a disposition; Corrective Action for systemic problems requiring a Corrective Action Plan; 4.15 take into consideration how your company delivers the services you provide to your customers, etc.; records need to be kept, Internal Quality Audits need to be conducted; training will need to be established for the owners/management and other full time personnel of the
company; servicing if you guarantee any aspect of your work.
Statistical Techniques could be the trends and analysis you identify from tracking nonconformances, corrective actions, customer complaints, etc.
If you are just starting outwith your ISO Project, I suggest you identify your processes and sub-processes, then when you have a true picture of your business as it is take and line the processes against the ISO elements and go from that point to fill in any deficient areas.
You may also want to consider ISO 9001:2000, which is due out December,28,2000.
Service areas can actually be great fun in both documenting and implementing, especially if you are creative.
