NPR 7150.2A does not include any notes for this requirement.

h2. 1.2 Applicability Across Classes

KEEP THIS SENTENCE IF THERE ARE NOT NOTES. REMOVE IF THERE ARE:
Appendix D of NPR 7150.2A does not include any notes for this requirement.Delivery includes, as applicable, Software User's Manual (as defined in Chapter 5), source files, executable software, procedures for creating executable software, procedures for modifying the software, and a Software Version Description. Open source software licenses are reviewed by the Center's Chief of Patent/Intellectual Property Counsel before being accepted into software development projects. Other documentation considered for delivery includes:
 
a. Summary and status of all accepted Change Requests to the baselined Software Requirements Specifications. 
b. Summary and status of all major software capability changes since baselining of the Software Design Documents. 
c. Summary and status of all major software tests (including development, verification, and performance testing). 
d. Summary and status of all Problem Reports written against the software. 
e. Summary and status of all software requirements deviations and waivers. 
f. Summary and status of all software user notes. 
g. Summary and status of all quality measures historically and for this software. 
h. Definition of open work, if any. 
i. Software configuration records defining the verified and validated software, including requirements verification data (e.g., requirements verification matrix). 
j. Final version of the software documentation, including the final Software Version Description document(s). 
k. Summary and status of any open software-related risks.

h1. 2. Rationale

addThe ultimate goal of software development is to provide a product to the customer.  To ensure proper understanding, use and maintenance of the delivered product, it is necessary that documentation accompany that delivery.

h1. 3. Guidance

Typical contents of a software delivery package for a completed software project include executables (the product), a user's manual, and a version description document that describes the delivered product.  Other items listed in the note for this NPR 7150.2 requirement may also be part of the delivery package as appropriate for the project and its software classification ([SWE-020]).  It is important, however, to keep in mind that the note which accompanies the requirement is only additional information and is not part of the requirement.

In addition to the items listed in this requirement, consider the following items for the software delivery package:

* Certifications^1^
* Software safety plan^2^
* Hazard analyses^2^
* Safety-critical software development audit reports^2^
* Safety-related verification reports^2^
* Installation instructions, including description of hardware environment^3^
* Operational constraints, including environmental limitations^3^
* Configuration files^3^
* Project documentation (e.g., software development/management plan (SDP/SMP), assurance plan, software requirements document (SRS), design documents, configuration management plan (CMP), test plan)^3^
* Testing performed and the results of those tests^3^
* Training manuals4, training agreement^5^
* Maintenance/service/support agreement, processes, procedures^5^

Both the delivered software and the delivered documentation are generated/pulled from the project's configuration management system ([SWE-085]) as a baseline to ensure the latest versions are delivered to the customer.

It is important to perform an audit prior to delivery to ensure that "all delivered products are complete, contain the proper versions, and that all discrepancies, open work, and deviations and waivers are properly documented and approved."^1^

Delivery package contents from a contracted software provider needs to be fully described in the contract to ensure the acquirer receives all critical information required to operate and maintain the software.  Other contract considerations related to delivery include:

* Ownership and delivery of source code 
* Usage considerations for off-the-shelf (OTS) software
* Delivery format, security6 and method for all deliverables
* Acceptance criteria ([SWE-034])
  
See the Acquisition Guidance topic in this handbook for additional guidance regarding delivery for contracted software development.

h2. 6. Lessons Learned

add

The NASA Lesson Learned database contains the following lessons learned related to delivery of software products:

* *Provide Detailed WBS for Flight Software in the RFP, Lesson Number: 0911*  "This organizational segregation of flight software from the spacecraft subsystems leads to a "lack of ownership" of the subsystem flight software by the Subsystem Manager. Typically, the Subsystem Manager is only concerned that he finalize his requirements and design prior to Spacecraft CDR. This in turn leads to late delivery of flight software ICDs, requirements, design algorithms, data constants, and test cases from the subsystem to the Flight Software Manager." ([http://www.nasa.gov/offices/oce/llis/0911.html])

* *Firmware Documentation*: "NASA should ensure that all firmware code, ..., is properly documented and archived for future reference. Further, NASA should ensure that it retains the rights to such software... Direction to deliver copies of the documentation (requirement, design, test, etc.) of the firmware controller software prepared as part of their software development process is being given to each vendor." ([http://www.nasa.gov/offices/oce/llis/1024.html])
