Scope of Work Acceptability (SCOPE OF WORK RULE)

(note4)

The scope of work must include the research and analyses that are necessary to develop credible assignment results.  

Comment: The scope of work is acceptable when it meets or exceeds:

• the expectations of parties who are regularly intended users for similar assignments; and

• what an appraiser’s peers’ actions would be in performing the same or a similar assignment.

Determining the scope of work is an ongoing process in an assignment. Information or conditions discovered during the course of an assignment might cause the appraiser to reconsider the scope of work.

An appraiser must be prepared to support the decision to exclude any investigation, information, method, or technique that would appear relevant to the client, another intended user, or the appraiser’s peers.

An appraiser must not allow assignment conditions to limit the scope of work to such a degree that the assignment results are not credible in the context of the intended use.

Comment: If relevant information is not available because of assignment conditions that limit research opportunities (such as conditions that place limitations on inspection or information gathering), an appraiser must withdraw from the assignment unless the appraiser can:

• modify the assignment conditions to expand the scope of work to include gathering the information; or

• use an extraordinary assumption about such information, if credible assignment results can still be developed.

An appraiser must not allow the intended use of an assignment or a client’s objectives to cause the assignment results to be biased.
