7.0 Functional Responsibilities and Implementation Plans

Using the guidance provided in the NASA Strategic Management Handbook, the Center ofExcellence for Structures and Materials has adopted the following five (5) specific functional

responsibilities:

1. Conduct a periodic assessment of the current technical capabilities in relation to future

Agency missions and technology requirements.

2. Maintain and enhance the preeminent technical capabilities distributed throughout the

Agency.

3. Proactively participate in planning future Agency programs.

4. Serve as the primary point-of-contact for requests for structures and materials technicalinformation and for requests to participate in urgent investigations of critical problems("911 calls").

5. Build strategic alliances / partnerships with all NASA Field Centers, other COE's,industry, academia, other Government Agencies, and international partners.

The tasks required to implement each functional responsibility are described in the

following sections.

7.1 Conduct a periodic assessment of the current technical capabilities in relationto future Agency missions and technology requirements.

A process has been developed for conducting the periodic assessment of the current.technical capabilities distributed throughout the COE Community. This process is outlined in theprocess flow diagram shown in Figure 3. The COE will implement the following specific tasks:

1. The COE Office will compile and publish an inventory of the Agency's structures and materials

capabilities. Each Center will provide the following data:• technical capabilities,• description of facilities and laboratories,• current FY programs and associated civil service workforce (FTE's),• recent accomplishments and problems solved,• identify future Agency missions/needs and technical requirements,• identify examples of a "technology push" that enables a future Agency mission.

2. Each Center will conduct a self-assessment of strengths, weaknesses, and gaps with respect to

Enterprise goals and objectives.

3. The COE Office will coordinate the Center self-assessments, identify overarching themes,

develop list of deficiencies, and benchmark NASA capabilities to those of outside organizations,as appropriate.

4. The COE Office will lead the development of recommendations to address deficiencies, andproactively advocate appropriate implementation of the recommendations.

5. Each Center will develop a Structures and Materials Facilities and Laboratories Brochuresuitable for public dissemination.

7.2 Maintain and enhance the preeminent technical capabilities distributed

throughout the Agency.

The responsibility to maintain and enhance the preeminent technical capabilities distributedthroughout the Agency resides with the line management at each participating Center. The COEwill establish Working Groups in specific technical areas that cross-cut the structures and materialscommunity. The purpose of these Working Groups will be to discuss common problems, share

experiences, and form partnerships where cooperative activities are mutually beneficial. It isanticipated that several Working Groups will be established as standing committees to address themaintenance and enhancement of technical skills and expertise. However, Working Groups toaddress the enhancement of Facilities and Laboratories will only be established when the need

arises from the periodic assessment of current technical capabilities. The COE will implement the

following specific tasks:

1. The COE Office will coordinate the establishment of Working Groups by conducting a canvas

of the COE Community to obtain a list of existing relevant Working Groups, identify candidatetechnical areas for new Working Groups, and gage the interest in participating. (Table 4 contains alist of some of the existing NASA Working Groups.)

2. The COE Office will initiate a discussion with existing Working Groups that may be

appropriate to facilitate the objectives of the COE.

3. Where sufficient interest exists to create a new Working Group, the COE Office will lead the

development of a charter, solicit names of the members from the interested Centers, and a kick-offmeeting will be organized.

4. The COE Community will voluntarily participate in those Working Groups that directly benefit

the participating Centers.

7.3 Proactively participate in planning future Agency programs.

A notional diagram of the NASA process for program creation, implementation, andmission support is shown in Figure 4. The COE will be proactive in planning future programs and

Agency missions. This proactive role will help insure that all future programs are planned with anappropriate structures and materials content. Also, visionary plans for long-term developments instructures and materials will be advocated as examples of technologies that can enable future

Agency missions that are not currently conceived. The (OE will implement the following tasks:

1. The COE Office will coordinate the support for planning future programs as requests are

received and opportunities identified.

2. The COE Community will voluntarily participate in the planning activities as

requests/opportunities arise.

3. The responsibility to communicate throughout the COE Community the information regardingrequests and opportunities is jointly shared by the COE Office and the COE Community members.

4. The COE Office will engage in regular discussions wi_:h key personnel in Enterprise and

Program Offices. These discussions are intended to be i_formational in content. (Advocacy forimplementing recommendations is part of the responsibility for conducting periodic assessments ofcurrent technical capabilities.)

5. The COE will organize and participate in workshops of specific technical issues of interest tothe COE Community. Emphasis will be given to the long-term view, especially where structuresand materials has an opportunity to provide a "technology push" that enables a future Agencymission. (Participation on the organizing committee and in the workshop is voluntary.)

7.4 Serve as the primary point-of-contact for requests for structures andmaterials technical information and for requests to participate in urgentinvestigations of critical problems ("911 calls").

In order to fulfill the reactive role illustrated notionally in Figure 4, the COE will implementthe following specific tasks:

1. The COE Office will respond to requests for technical information as the need arises. The COEOffice will use the Directory of Key Personnel (points-of-contact included in the CapabilitiesInventory) provided by each Center as a source of referrals when the Office cannot fulfill a request.

2. The COE Office will assign action items to appropriate Centers when requests to participate inurgent investigations of critical problems ("911 calls") are received.

3. The COE Community will voluntarily participate in "911 calls" at a level judged to beappropriate by the Center(s) receiving the request from the COE Office.

4. Those requests for technical information or "911 calls" that involve multiple Centers will becommunicated throughout the COE Community by the COE Office and/or the members of theCommunity.

7.5 Build strategic alliances / partnerships with all NASA Field Centers, otherCOE's, industry, academia, other Government Agencies, and internationalpartners.

The foundation of the Cehter'of Excellence for Structures and Materials is the partnershipestablished among the NASA Field Centers. The voluntary participation of all NASA Field

Centers in the COE partnership is viewed to be essential for success. The NASA community ofexcellence in structures and materials will benefit from alliances with external organizations.Numerous alliances and partnerships already exist between members of the COE Community andexternal organizations.

In the context of the COE Implementation Plan, an alliance will be defined as an enduringrelationship, connecting parties with common interests (needs), that does not disappear withspecific programs. The COE will implement the following specific tasks:

1. The COE Office will canvas the COE Community, compile, and distribute a list of existingstructures and materials alliances. (Table 5 contains a list of some of the existing alliances.)

2. The COE Community will identify opportunities for oth_._r community partners to join existingalliances.

3. The list of alliances will be evaluated by the COE Office and Community to identify needs notcurrently fulfilled by the existing alliances.

4. The COE Office will inform the COE Community of opportunities to form new alliances.

5. The specific actions to form new alliances will be the vcluntary initiative of the individualmembers of the COE Community.

10.0 Agencywide Collaborative Activity Leads to Revolutionary New Technology

It is interesting to note that one of NASA's most significant and lasting technicalcontributions in the field of structures and materials was a direct result of a collaborative effort

among all the NASA Field Centers. In January 1964, key personnel from all NASA Field Centersgathered at Headquarters in Washington to discuss efforts underway to improve structural analysismethods, particularly as it applied to the shell configurations commonly used in aerospacestructure. Each representative described how his group had written special-purpose computerprograms to analyze particular shell configurations. After this meeting, NASA Headquarterscommissioned an ad hoc committee, with a representative from each NASA Center, to investigate

the state of analysis methods in the aerospace industry. The first action taken by the committeewas to visit the aircraft companies which were doing prominent work in developing computer-

commlt_.ee s ws_ts to the aircraft companiesbased advanced structural analysis methods. The " " ' " "revealed that no single computer program incorporated enough of the best analysis features desired

by NASA. Therefore, the committee recommended to Headquarters that NASA sponsor thedevelopment of its own computer program as a means to upgrade the analytical capability of thewhole aerospace industry. Headquarters endorsed the recommendation and selected Goddard

Space Flight Center (GSFC) to manage the development of the computer program. Under theleadership of GSFC, the ad hoc committee developed a visionary and thorough technicalspecification for the computer program and released a Request for Proposals in July of 1965.Much of the eventual success of the project was directly a:tributed to the initial work of the NASAcommittee in developing the thorough specification for the computer program [3]. In December1965, NASA awarded two Phase I contracts for preparation of a Technical Evaluation Report, one

to a team led by the MacNeal-Schwendler Corporation (MSC) and one to the team led by DouglasAircraft Company. After an evaluation of the two competing Phase I Reports and the associatedPhase II proposals, MSC was selected as the recipient of the Phase II contract and begandevelopment of the computer program in July 1966. Shoaly thereafter, NASA designated thename of the computer program to be the N_..AASAS__T_Tructur_lANalysis (NASTRAN) ComputerProgram. The contracting team completed the computer program in 1969 and delivered it to all theNASA Field Centers. In February 1970, the Program Office at Goddard was disbanded. Later

that year, NASA Headquarters established the NASTRAN Systems Management Office (NSMO)at Langley Research Center. The NSMO had the dual mission of maintaining NASTRAN anddeveloping new capabilities for the program. A NASTRAN Advisory Group was set up to

14

provideguidanceto theNSMO. ThisAdvisoryGroupconsistedof membersfrom eachof theNASACentersandwas,in effect,acontinuationof theadhoccommitteewhichdraftedtheinitialNASTRANspecificationin 1964.

11.0 Concluding Remarks: Keys to Success

The implementation plan documented herein relies on three fundamental keys to success.These keys to success are building the COE community, a commitment of resources by theparticipating Centers, and developing high-payoff advanced technologies. First, the Structures andMaterials COE Community is built on the voluntary partnership among 9 NASA Field Centers.Strategic alliances with external organizations will expand the Community. Collaborative activities

among the Community partners will evolve from the thorough knowledge of the technicalcapabilities of each Community member. The COE communications network will fostercollaboration. Second, the COE Community does not anticipate that the COE Office will be a

source of funding to support research, technology development, or mission support. However,membership in the COE Community requires that each Center provide those resources necessary toimplement the responsibilities listed in section 9.2 above. Third, it is encumbent upon the COECommunity to identify and develop those high-payoff advanced technologies that enable future

Agency missions. Each of these three "keys to success" are essential to achieving a meaningfulfulfillment of the requirements set forth in this implementation plan.

Appendix: Inventory of Technical Capabilities

This Appendix contains the Agencywide inventory of structures and materials technical

capabilities. The inventory contains the following data for each Center:

• summary of technical capabilities• directory of technical points of contact• FY 98 programs and the associated structures and materials civil service workforce• brief summaries of recent technical accomplishments

• technical skills mapped against specific applications• descriptions of the dedicated structures and materials facilities and laboratories.

Some of the data in the inventory, such as the listing of programs and the associated civil

service workforce, may only be valid for the year in which it was compiled, FY 98. The COEexpects to update and publish the inventory on a periodic basis.
