Note that this is an auto-generated TOC; as long as you retain the
heading styles the TOC can be easily updated.

# Abstract

In the abstract, first explain the general background behind the
system---what it does, how it works, where it goes, its possible
configurations, the general environment, etc. Then, break down the
system into its components, and describe what they do.

Once you have described the system, briefly enumerate each of the
individual mechanisms in the system: latches, hinges, EVA bolts,
anything that moves. Don't worry about providing a lot of detail here;
that will be done in later sections.

Some tips:

-   Try to include some pictures of the overall system from different
    angles, or in the different configurations it may assume. Standard
    orthogonal views are good too. Label your pictures as figures for
    reference from within the text. Add notes to the pictures to point
    out important features. Envelope dimension or other important
    dimensions can be shown here too. Also, try to include a coordinate
    system with at least one of the pictures so that directions
    specified with vector components later have a reference.

-   Be sure to spell out all of your acronyms at least once before you
    start using them exclusively.

-   Spell check the document!

#### Figure 1-2 {#figure-1-2 .unnumbered}

Clip Art doesn't have orthogonal views of an airplane, but you get the
idea.

# Fault Tolerance

At a minimum, this section should include the fault tolerance worksheet
matrix that explains the controls on each failure of the operational
scenario. Any clarifications to the matrix should be included here.

![](media/image2.wmf)

This is an embedded Excel spreadsheet. You should be able to
double-click it and edit it but it may need to be reformatted or pasted
as a word table to get your final product to fit right, especially if it
grows to more than one page. Instructions and an example are included
farther down. A separate Excel template is also available.

#  {#section-2 .unnumbered}

# Individual Mechanism

In these sections, you will discuss each mechanism individually. Be sure
to discuss all components, modes of operation, methods of operation,
operation scenarios, operating environments and redundancy. If the
mechanism is intended to be designated as DFMR, a DFMR matrix must be
filled out and included in Appendix A. Reference this matrix here.
However, even if a mechanism does not count on a DFMR designation, it is
suggested that it follow DFMR practices anyway and be included in this
matrix.

The primary purpose of this document is to address the verification
activities planned for the mechanism in order to meet requirements. This
section where that should be located. At a minimum it must discuss the
test environment and pass/fail criteria for each test, and the
verification method and rationale if testing is not to be performed.
Summarize the activities discussed here in the verification matrix
included in Appendix B. If a detailed test plan is available, reference
it here and include it in another appendix.

Pictures and cross-sections will help reviewers understand the
mechanism.

# Appendix A -- DFMR Matrix {#appendix-a-dfmr-matrix .unnumbered}

Appendix A should contain the DFMR Matrix for all of the mechanisms.

![](media/image4.wmf)

This is an embedded Excel spreadsheet. If you double-click it you should
be able to see and edit the whole thing it but it will need to be
reformatted or pasted as a word table to make the entire table visible.
A separate Excel template is also available.

# Appendix B -- Functional Verification Matrix {#appendix-b-functional-verification-matrix .unnumbered}

Appendix B should contain the Functional Verification Matrix for the
mechanism. The matrix should act mainly as a summary. Provide enough
information so that the verification activities can be understood (what
was done, report numbers, etc.) but save the details for the body of the
report.

# ![](media/image5.wmf) {#section-3 .unnumbered}

This is an embedded Excel spreadsheet. If you double-click it you should
be able to see and edit the whole thing it but it will need to be
reformatted or pasted as a word table to make the entire table visible.
A separate Excel template is also available.

# Appendix C {#appendix-c .unnumbered}

The remaining appendices should contain any documents referenced in the
body or other appendices of the MSVP, or any other information that does
not fit neatly into the body of the report. The documents in the
appendices can be provided separately from the MSVP; if this is the
case, please list these documents and note them as provided separately.
Examples would include tolerance analyses, test plans or reports, the
fracture control plan, hazard reports or the RAESR, etc.
