DFRC ITA Technical Standards Discussion Raymond Kacmar DFRC ITA http://standards.nasa.gov
The DFRC implementation of the ITA is a high-level Center staff function that provides senior technical and management oversight of select engineering activities, Mission and Ground Operations, and S&MA efforts in support of the programs. Key Characteristics of the ITA We will not “reinvent the wheel”. We recognize that much of what is called for within CAIB R7.51 is already done at DFRC, and we will incorporate that within the context of our operations (by independent funding and providing dedicated resources as necessary). For example: Flight Readiness Reviews/Airworthiness and Flight Safety Review Board activities Flight Assurance activities Many of the ongoing independent assessment activities http://standards.nasa.gov
Key Characteristics (Continued) We will improve those areas where DFRC is currently performing but have resource issues, for example: Lessons Learned support Systems Management Office - use ITA staffing to expand their presence There are also some areas that are not done at DFRC and we will build the capability to accomplish them. Centerwide Tracking and Trending Facilities independent assessment Implementation of Waiver Issues http://standards.nasa.gov
Managed collaboratively by the ITA Board, consisting of the DFRC Chief Engineer and S&MA Director, and the DFRC NESC Chief Engineer (non-voting) The ITA Board reports to the Center Director The ITA Board has signature authority (waivers, etc.) An ITA Director will run day-to-day ITA operations The ITA will consist of a core team, rotational assignees (1 - 2 year), matrixed experts and contractor support – 13 FTE , 2 WYE (FY05) Some realignment of responsibility may be required, but no functionality will be duplicated We recognize that success will be measured by becoming an asset, not a burden to the center. Again, a lot of the effort will not be new work but work already being done at the center. The ITA will encourage projects and line engineering to provide feedback on ITA activities. ITA Structure and Function http://standards.nasa.gov
Manage technical standards (including the waiver-granting authority of these standards). Approve safety and reliability assessment plans and products for all mission programs. Conduct periodic independent assessments using safety, reliability, quality, trend and risk analysis techniques as a check against similar program and project analyses. Supplement program and project problem reporting systems with independent inputs. Provide formal verification to appropriate decision authorities of mission and acquisition milestone readiness. Major ITA Functions http://standards.nasa.gov
There are two principal elements in executing engineering work: The first, is execution of line engineering work (work that produces a mission-related product) that is done for programs by a matrixed organization. The second, is that to ensure that the line engineering process is able to perform its work relatively dispassionately, there is an additional group that acts as an arbiter for technical issues. This group maintains the authority for applying and modifying technical standards, identifying issues and resolving technical disputes between line engineering and program line management. Note that people within the line engineering organization may conduct some aspects of ITA work (and vice versa) through appropriately controlled processes. Independent Authority http://standards.nasa.gov
For the NASA engineering community, Headquarters (through the Office of the Chief Engineer), provides overall policy, coordination, standardization, oversight, and when necessary direction of field activity engineering work. In the context of the ITA, this principally consists of: approving Agency-wide standardized engineering practices, including collaborative processes; providing policy and direction for the establishment, implementation, and modification of technical standards, including delegation of authority to Centers as appropriate; Headquarters ITA Functions http://standards.nasa.gov
Field activities (through the Center Director) provide independent controls and oversight of the line engineering work through ITA functions. In the context of the ITA, this principally consists of approving and overseeing standardized and project-specific engineering practices at each Center; approving and overseeing the implementation and modification of program-specific standards for each Center as delegated by Headquarters; providing oversight of line engineering work conducted in support of projects; establishing and executing ITA processes at Centers; acting as the primary technical authority for engineering-related disputes and issues within projects and programs, as delegated by Headquarters. Field ITA Functions http://standards.nasa.gov
Technical standards include Agency, Center, program, project, industry, and international standard processes and requirements for generically performing technical work or producing manufactured equipment, and are covered within NPD 8070.6, “Technical Standards. Project functional requirements include performance requirements specific to that project, and are covered within NPD 7120.4, “Program/Project Management.” For example, technical standards might provide analytic techniques and part requirements for a vehicle, project functional requirements might provide the velocity, volume, and mass requirements for that vehicle. Technical standards vs. Project requirements http://standards.nasa.gov
Technical standards: are developed or adopted by the engineering community, approved by the ITA and are applied and executed by line engineering personnel, and this application and execution is in turn overseen by both line engineering management and the ITA. By contrast, project functional requirements are established by project management, executed by line engineering using technical standards as the means for execution, and this execution is overseen by cognizant enterprise and Center programmatic management; Independent Agency oversight of this process is provided by associated Program Management Councils, the Independent Program Assessment Office, and Center Systems Management Offices. Technical standards vs. Project requirements Cont’d http://standards.nasa.gov
During authorization and formulation of each project, the list of applicable technical standards (including Center and program/project standards) will: be proposed by line engineering, concurred with by the program/project manager, and approved by the ITA manager for that Center as delegated by the NASA Chief Engineer. In addition, this list of standards will identify any exceptional cases in which standards are not intended to be incorporated in relevant project contracts. http://standards.nasa.gov
Most technical issues will be resolved among project management and the line engineering directorate based on a reasoned resolution of competing technical, schedule, and cost considerations. In such cases, appropriate technical, cost, and schedule strategies can often be developed that satisfy all requirements, or which lead to an appropriately developed and reviewed revision to those requirements. This process is overseen continually by the Center element of the ITA, and ITA actions are required for those cases in which technical standard requirements are proposed to be modified. In the event there are issues that are not satisfactorily resolved within the Center, or which require a solution for which the Center does not have authority or resources, the issue will be identified to the cognizant Mission Office Associate Administrator and the NASA Chief Engineer for concurrent resolution, including appropriately justified recommendations from program management, line engineering, and the Center element of the ITA on alternate courses of action. In the very unlikely event this process does not reach concurrent resolution, the issue will be identified to the NASA Administrator for final resolution.
