What is NOT an appropriate workfile arrangement for multiple appraisers working on a consulting assignment?

Sharing a single workfile is not an appropriate arrangement for multiple appraisers working on a consulting assignment because it raises significant issues regarding accountability, confidentiality, and individual contributions. Each appraiser is responsible for maintaining their own workfile, which includes supporting documentation, analysis, and findings relevant to their specific contributions to the assignment. This ensures that all work is traceable and meets the requirements set forth by the Uniform Standards of Professional Appraisal Practice (USPAP).

When each appraiser maintains individual files, they can organize their work according to their methodologies and standards, enhancing the clarity and accountability of the contributions. Collaborative documentation allows appraisers to share insights and findings effectively, but this should not be conflated with the maintenance of a single workfile, as distinct workfiles reinforce the individual responsibilities of each appraiser.

Co-writing the final report is also seen as a beneficial practice that combines the appraisers' inputs into a cohesive document while allowing for clear differentiation of each person’s contributions. Thus, maintaining separate workfiles fosters a structured and professional approach while aligning with USPAP guidelines, emphasizing the importance of personal accountability and precise documentation in appraisal practice.
