20.5 - Documentation and Working Papers
(Rev. 308, Issued: 10-26-18 Effective: 09- 01- 18, Implementation: 11-27-18)
The contractor shall document through its working papers, the process it employed to support its internal
control certification. This documentation shall include working papers so that a CMS reviewer can conclude
that the Risk Assessment process as described in Section 20.1 follows or exceeds these guidelines, and that
the Control Activities (Section 10.2.3.3) identified to support the high risk control objectives selected for
review are current and clearly stated. Finally, the CPIC documentation shall demonstrate how the Testing
Methods employed comply with the general parameters as described in Section 20.4 for the purpose of
Control Activity validation.
Working papers contain evidence accumulated throughout the review to support the work performed, the
results of the review, including findings made, the judgment and/or conclusion of the reviewers. They are
the records kept by the reviewer of the procedures applied, the tests performed, the information obtained,
and the pertinent judgment and/or conclusions reached in the review process. Examples of working papers
are review programs, analyses, memoranda, letters of confirmation and representation, abstracts of
documents, and schedules or commentaries prepared or obtained by the reviewer. Working papers may be
in the form of data stored on tapes, film, or other media.
General Content of Working Papers - Working papers should ordinarily include documentation showing
that:
•
The work has been adequately planned and supervised.
•
The review evidence obtained, the reviewing procedures applied, and the testing performed has
provided sufficient, competent evidential matter to support the reviewer's judgments and/or
conclusions.
Format of Working Papers - Working paper requirements should ensure that the working papers follow
certain standards. As a whole, a good set of working papers should contain the following:
•
The objectives, scope, methodology, and the results of the review.
•
Proper support for findings, judgments and/or conclusions, and to document the nature and scope of
the work conducted.
•
Sufficient information so that supplementary oral explanations are not required.
•
Adequate indexing and cross-referencing, and summaries and lead schedules, as appropriate.
•
Date and signature by the preparer and reviewer.
•
Evidence of supervisory review of the work.
•
Proper heading should be given to the basic content of the working papers.
