66 THEMIS & RHESSI NRC Irvine 2/01/2005 PI Mode Experience Peter R. Harvey Project Manager Space Sciences Laboratory University of California, Berkeley

67 THEMIS & RHESSI NRC Irvine 2/01/2005 Tasks (1) examine and assess the selection process and objectives for PI-led missions, including the balance between science objectives and cost and management criteria, (2) examine the roles, relationships, and authority among members of the PI-team (e.g., PI, university, industry, field center) in past missions, (3) identify lessons learned from the scientific and technical performance of previous PI-led missions, (4) investigate and analyze the factors contributing to cost overruns of missions, including any requirements that are imposed on PI-led projects during their development, (5) identify opportunities for knowledge transfer to new PIs and sustained technical management experience throughout the program, and (6) identify lessons learned and recommend practices and incentives for improving the overall conduct of future PI-led missions. SSB Subcommittee Tasks

68 THEMIS & RHESSI NRC Irvine 2/01/2005 Questions 1.Please list those problems and challenges that were distinct from a program-led mission that you have faced/are facing in your effort to accomplish your proposed PI-led project. What is the status of each or what was the outcome? 2.What were the responsibilities of the program manager, project manager, and PI? 3.Comments on communications and interactions among the PI, PM (project manager), NASA, industry, and other key players? 4.What aspects of the PI program do you think facilitated your work and getting the mission done on time and on budget, and what do you consider the most significant obstacles in achieving mission success? 5.What changes would you make to the way PI-led missions are defined and/or executed to improve them at the proposal, development, and/or implementation phases; 6.Please comment on lessons learned from your experience managing a PI mission(s). 7.Would you do it again, why or why not? SSB Subcommittee Questions

69 THEMIS & RHESSI NRC Irvine 2/01/2005 PI mode is cost-capped but PL mode is not operating under strict cost cap. –Problems and challenges same in both, but solutions are different –PI mode provides flexibility not available in PL mode; this helps both science and costs RHESSI Examples PL mode viewPI mode view HESSI cryocooler challengingBuy expensive ($$)Buy many and test Support with in-house development JPL vibration table broke HESSIMajor overrun ($$)SAI w/ UCB joint rebuilt I&T at UCB HESSI launch before solar maxWhen we can (sci)Can do now: simplify spacecraft HESSI GridsBuy one and monitor ($$)Parallel path HESSI Operations expensiveOK, nominal ($$)Build UCB antenna, use automation Q1. PI vs. PL mode: Problems and Challenges

70 THEMIS & RHESSI NRC Irvine 2/01/2005 THEMIS Examples PL mode viewPI mode view THEMIS SST too noisyRelax requirements (SCI)Develop in-house THEMIS schedule riskDelay launch ($$, SCI)Change I&T venue (org-chart) THEMIS mass growthSend help ($$) or accept (sci)Instruments accommodate a new tank THEMIS thermal/power Restrict s/c attitudes (risk)Instrument-bus personnel work together THEMIS cost projectionOK, it was tough to do ($$)Reorganize team to recover costs IIRT reports to centerNaturalDriven not by cost/schedule but only risk Authority over PM, PL, PI, and Science Defies PI mode – and notion of cost cap Extra reviews (ITA, Code500)Bring them onSame as above Q1. PI vs. PL mode: Problems and Challenges

71 THEMIS & RHESSI NRC Irvine 2/01/2005 Status and Outcome: All problems retired successfully due to flexibility of the PI mode, relative to PL mode Notable positive attributes of PI mode (should be strengthened): One contract and a clear line of authority to PI-PM allows team to: Trade effectively between science, mission design, schedule and cost Exercise parallel paths and implement at critical junctures Re-organize team efficiently when in trouble Work as a single-team with instruments accommodating spacecraft and vice-versa Technically experienced PI institution ensures science goals are met at cost by having: Good technical insight into mission elements and capability to determine risks early Capability to line-up in-house or new partner solutions when critical to mission success Notable risks of PI mode as implemented currently Line of authority to PI-PM that goes with responsibility to stay on cost is threatened: IIRT, AETD, Code 500, ITA (technical reviews) which have power over PI-PM Q1. PI vs. PL mode: Problem Status and Outcome

72 THEMIS & RHESSI NRC Irvine 2/01/2005 AO-01-OSS-03 (Same for RHESSI and THEMIS) Explorer program: Designed to utilize streamlined and efficient management approaches Seeks PIs who commit to cost limits, control business and technical processes The responsibility for implementing a selected investigation rests with the Principal Investigator (PI) and the investigation team, which will have a large degree of freedom with which to accomplish its proposed objectives with appropriate NASA oversight to ensure mission success. GSFC is responsible for NASA's fiduciary responsibility to ensure that Explorer missions are achieved in compliance with the cost, schedule, performance, reliability, and safety requirements committed to by the PI. GSFC's involvement in this role may vary from mission to mission, depending on the implementing organization and other programmatic considerations. Q2. Responsibilities (Explorer AO)

73 THEMIS & RHESSI NRC Irvine 2/01/2005 THEMIS selection letter March 22, 2003. From: AA for Space Science To: THEMIS PI “The Explorer Program Office, located at NASA Goddard Space Flight Center (GSFC) in Greenbelt, Maryland, is responsible for overall management of the Explorer program, while explorer program definition and project selection remain at NASA Headquarters. For your investigation, project management is assigned to the University of California at Berkeley as outlined in your proposal. The project will be required to regularly report status to the Explorer Program Office and to the GSFC Program Management Council (PMC).” Q2. Responsibilities at THEMIS CSR plan review, THEMIS selection (2003)

74 THEMIS & RHESSI NRC Irvine 2/01/2005 Responsibilities Mission Manager (Frank Snow, GSFC) Works with KSC for Launch Vehicle, Launch Services Works with HQ for ODA and International Agreements, Status Works with GSFC engineering for variety of support items Works with JPL for Environmental Test Finances Project Manager (Peter Harvey, UCB) Works with S/C Contractor Works with Instrument developers Works with Ground Based Observatory developers Works with Ground Station Developer (RHESSI) Principal Investigators (Robert Lin, Vassilis Angelopoulos, UCB) Works with Science Team to define Measurement Requirements Works with Operations Team to define Mission Profile Works with Instrument Teams to detail capabilities Q2. THEMIS Roles and Responsibilities

75 THEMIS & RHESSI NRC Irvine 2/01/2005 Sets Explorer Guidelines, (based on GSFC practices), reports to GPMC and HQ Ensures adherence to margins,resources and requirements committed to by PI (e.g., INST-001). If margins are threatened, GSFC recommends action, offers resources, takes on more active role in technical decisions and resource management. Review teams: Peer, IIRT Q2. THEMIS proposed authority lines IIRT (formal): Ensures, for MM, technical, schedule and cost margins are met. Recommends but does not enforce actions to PM. An asset for both MM and PM. Disposition of actions within PM authority. Peer (informal): Ferrets out issues before they become problems. Disposition within subsystem. Ultimate closure of issues by PM. Day-to-day program management for the PI, within allocated resources. Science/Technical decisions involve PI. Reports resource trends and margins to PI and Explorers office. Responsibility and authority to conduct investigation within proposed resources. Delegates daily management to PM. Reports to GSFC (resource and science margins) and HQ (decisions that affect L1).

76 THEMIS & RHESSI NRC Irvine 2/01/2005 THEMIS Confirmation Letter, May 4, 2004 From: AA for Space Science, Ed Weiler To: GSFC Director, Al Diaz “Based on the THEMIS project’s presentation on April 22, 2004, to the Enterprise Program Management Council, I approve THEMIS to proceed into mission implementation. … This is a cost-capped mission requiring tight control in order to maintain cost and international schedule commitments for launch in October 2006. The project in conjunction with the Explorer Program Office and GSFC’s engineering directorate shall provide status on the development and conduct schedule reviews of the spacecraft every 2 months. This oversight will serve to facilitate early detection and correction of problems thereby improving mission success.” Q2. Responsibilities at THEMIS confirmation (May 4, 2004)

77 THEMIS & RHESSI NRC Irvine 2/01/2005 Q2. THEMIS actual authority lines since confirmation (2004+) SMO office UCB PI, PM, MSE… Science, Resource, Cost or Subsystem (Swales, Instr.) Explorers Office MM, OM, other IIRT Peer Review Panel GPMC GSFC Director HQ GSFC Code 500 Engr Review Team RAO ITA

78 THEMIS & RHESSI NRC Irvine 2/01/2005 Reason for change: GSFC is told by HQ that the it has responsibility for project success. Therefore, it is natural that GSFC will assume the authority to ensure mission success, treating THEMIS as any GSFC mission, implemented in accordance with its own management practices and heritage. Effects: Mitigation plans require review and approval if not proposed in CSR Organization changes take a long time to make and are perceived risky GSFC involved with subsystems Involvement often construed as direction GSFC a stake-holder in status quo, reluctance towards alternate paths GPMC using own PL-mode management practices and heritage Cost adherence no longer a priority (HQ picked mission!) Risk-adversity addressed thru formal review channels drives decisions Resources and trades discussed openly with subs, outside of PI sphere Q2. Line of authority evolution: reason for PI mode change and effects

79 THEMIS & RHESSI NRC Irvine 2/01/2005 Practical Resolution: Constant, open, direct communications between PI-PM and Explorers office Amicable working relationship and capable team members Strong UCB ties with Explorers and GSFC allow efficient interaction Q2. Line of authority evolution: day-to-day implementation

80 THEMIS & RHESSI NRC Irvine 2/01/2005 Q2. Line of authority evolution risks and recommendations Risks: Possible misunderstanding of sub-contractors Line of authority confused Top-down decisions may risk science Bottom-up decisions take long time to review and implement (inefficient) Management practices at UCB and GSFC different Who is committed to cost (PI, GSFC, both)? Unclear HQ guidance. Who is responsible for science adherence? Unclear HQ guidance. Recommendation: Authority and responsibility must lie at the same place That place should be same for technical resources and science The appropriate place is where the science is conducted unless delegated PI flexibility to trade science, cost and technical resources depends on that

81 THEMIS & RHESSI NRC Irvine 2/01/2005 Q3. Communications Obstacles to Work Teaming Arrangements  UCB was and is Prime on RHESSI and THEMIS.  Spectrum Astro / Swales Aerospace are the Spacecraft Subcontractors  In Both Projects, GSFC Generally Ignores Relationship between UCB and S/C  GSFC Review Teams & Engineers Often Direct Effort at S/C Contractor  S/C Contractor Uses This to Explain Cost Overruns NASA GSFC UCB S/C Contractor Contractual Arrangement NASA GSFC UCBS/C Contractor Effective Arrangement

82 THEMIS & RHESSI NRC Irvine 2/01/2005 Q3. Communications Facilitators to Efficient Communications How PI deals with current situation (I.e., effective PI mode arrangement)  Recognize GSFC holds the contract and go with the flow  Emphasize team-effort and strategic (as opposed to tactical) success  Agree with s/c contractor and GSFC on “terms of engagement” (even if moot point)  Information is key: obtain from both GSFC and subcontractors  Extract information when not provided, utilize agreement above  Open and honest communication between PI-PM and MM (parallel paths, costs, and outlook)  Pick main battles where it matters: on technical and science issues  Call out and tabulate out-of-scope items; insist only on heavy-hitters  Recognize that Explorers Program is on the same boat, change is coming from further above !

83 THEMIS & RHESSI NRC Irvine 2/01/2005 Q4. PI Mode Aspects Aspects Facilitating Work Flexibility in implementing technical and organizational workarounds Full trade space at the disposal of science under cost Parallel paths available even though not called out at proposal Direct Involvement of PI with Spacecraft & Instrument Developers Instruments Have Been Defined Well and Early Full Authority to Improve Spacecraft Design Obstacles to Work GPMC and Explorers office assuming more direct role in management Have different management style more in line with PL mode (not capped) NASA IIRT Action Items Not Constrained by Cost or Schedule ITAR NASA Declines to Provide Interface to State Dept for PI University Pressures Team to Steer Clear of ITAR required activities Project Has to Work Around ITAR Rules (Change Flow, Personnel, etc)

84 THEMIS & RHESSI NRC Irvine 2/01/2005 Q5. PI Mode Improvements, #1 PI Mode Definition Recognize that under GSFC management, PI mode under cost cap a challenge Mission Can Be PI Mode, or GSFC Mode (=PL Mode), but Not Both Unless GSFC is the proposing PI institution HQ must take responsibility for PI mode mission selection. Not GSFC. HQ must clarify that PI institution has the responsibility and authority: Authority and responsibility for both science and implementation must be at same place, and this should be the place committed to deliver on cost Place triggers for GSFC involvement in management If cost to complete or technical resources are threatened GSFC should ensure commitments by PI institution are met Ensures science and L1 commitments are on track Informs HQ of progress and projections Ensures processes and parts are in line with NASA expectations A resource for PI institution to get back on track if problems arise

85 THEMIS & RHESSI NRC Irvine 2/01/2005 Phase A Make Phase A Non-Competitive Allows Project to Develop Team Members Allows Team to Fully Explore (Detail) Cost Estimate HESSI Cost was Estimated Better than THEMIS Implementation Give PI Authority over the Project Do not Change Rules-of-the-Road Mid-Course Remove IIRT or Have it Report to the PI Remove the Mission Signoff Requirement from GSFC Development Discourage Developments During a Project Fund Development Efforts for Future Projects. Q5. PI Mode Improvements, #2

86 THEMIS & RHESSI NRC Irvine 2/01/2005 Q6. PI Mode Lessons Lessons Learned Technology Development  Very High Risk to Depend Upon Development. Always Have a Descope Position.  HESSI Developed a Backup Supplier of the 20 micron grids and Needed it.  HESSI Developed a Backup Roll Angle Sensor and Needed it  THEMIS Developed Backup Detectors and Needed them  THEMIS Is Currently Developing Multiple Backup Systems RECOMMENDATION : PI Team Should Substantially Fund Backups Proposal Development  HESSI was Proposed Multiple Times.  Partner Selection Process Involved 7 Companies  Selected a Small Growing Company Who Needed HESSI to Work.  HESSI S/C partner performance was considered Very Good. RECOMMENDATION : Select Partner Who Has a Huge Interest in Project Success

87 THEMIS & RHESSI NRC Irvine 2/01/2005 Q6. PI Mode Lessons Lessons Learned University Infrastructure  Very Small, Independent Research Groups Attached to Dean  Personnel Are Hired into Career Positions at Lower-than-Average Salary with Good Benefits.  Engineers are Motivated and Enthusiastic About Scientific Research.  Typical Manager is a Willing Engineer  No Centralized Training Program for Managers, Engineers, or Technicians  Internal Cost and Schedule Practices Only.  Minimal Subcontracting Work (SOW, RFP, Contracts, Termination Liability, Rate Changes, Requirement Flow Downs, Monitoring Technical Progress, etc...) RECOMMENDATION(s) [1] Invest in Training Programs for Personnel. [2] Investigate Supplemental Aerospace Support (e.g. Thermal, Contamination...) [3] Hire Project Contracting Officer, Scheduler, Accountant [4] Train Your Engineers to Be Subcontract Technical Monitors

88 THEMIS & RHESSI NRC Irvine 2/01/2005 Q7. The Future Would You Do it Again? Will there be more PI-Missions? Yes; based upon their success Definitely cost effective SMEX/MIDEX Provide Science results as well as large missions Do it Again? As Long as THEMIS gets on a chart like this one.
