Characteristics of Complex Defense Projects
� Life cycle 40-50 years cradle to grave � Driven by external threat environment � Almost always requires new technology
development � Almost always ‘in design’ (planned and
unplanned iterations) throughout system life � Strong political influence factors � Many technologies in each system and
subsystem

+
- Environment & Infrastructure
� Contractual project challenges � Design Agent errors occurred (for various reasons
including CAD limitations and as-built variations),and became government liabilities in the shipyard
� Key goal is to keep GFE off the critical path � ‘Constructive changes’ frequently occur ‘on the
deckplates’ � Principal players geographically separated
� NAVSEA in Washington � Newport News Shipbuilding in Tidewater VA area � IBM Federal Systems in Manassas, VA � Electric Boat in Groton, CT
23 Oct 2003 - ESD.36J SPM 14
+
- Environment & Infrastructure
� Mid-1980s: no MS Project, no graphical tools, no SE tools (requirements mgmt, risk mgmt, etc.) � Mainframe and mini-based text schedules, PERT
calculations � Only PC-based tools were early spreadsheets
(VisiCalc, Symphony) and word processors (WordStar)
� No integration across projects, contracts � No requirement or tools for integration � Executing PM (SUPSHIP) responsible for ultimate
delivery

Enterprise haschosen what productor system to develop
� Each acquisitionmanager focused onown contract & ‘image’
� Integration, evenintegrated planning, isoften only possible atthe shipyard level
� All integration and testplans & procedures for688i & BSY-1 are new and untested
� Risk assessment & management requireintense ‘manual’ integration effort
� People, in each organization, are thekey resources
� All contractors are incentivized for both cost and delivery
23 Oct 2003 - ESD.36J SPM 16
+
- Management Tools
� Each major organization used some variation of a scheduling and planning system � Most mainframe-based, ‘green bar’ text output � Usually structured around either material/cost flow
(shipyard) or CPM/PERT (Navy and IBM) � At the integrated implementation level, these
data must be integrated and tracked‘manually’: � Derive integrated GANTT using major milestone
information from each organization � Perform independent risk assessment & determine
options for mitigation
23 Oct 2003 - ESD.36J SPM 17
+
- Monitoring the Integrated Project
� In the absence of ‘automated’ tools & processes, critical decision support data must be assembled ‘manually’: � Daily shipyard project reviews- know the capabilities and
credibility of the attendees � Reviews at major contributing organizations (IBM, NUSC, etc.) on
a frequent basis � Attendance and substantive technical input at frequent integrated
reviews (often created by project manager) � Homework- understand all technologies and key components at
the system level, dive deeper when required � Outside of meetings, ‘progress reviews’ in person, ‘on the
deckplates’ (or integration lab, etc.) � Learn the strengths, weaknesses, motivations, credibility and
commitment level of all key project personnel � Repeatedly update personal assessment of risks/mitigation
23 Oct 2003 - ESD.36J SPM 19
+
- Managing the Integrated Project ‘Rules’ that worked:� Never ‘manage’ from an office- lead from the scene
of the action � Develop two-way trust with project personnel
� Go to bat for the people and teams, with data � Ensure your input is heard at evaluation time
� Use people as teachers in their areas- have them assess the risk in their portion of the project
� Challenge assumptions on schedules and risks � Assemble your own ‘progress report’, whether for
senior management or yourself, on a regular basis-emphasize content, not prose
� Elevate risks and problems, with data and recommendations

- Software Development Challenges
� IBM & subcontractors had formidable task: � Integrate numerous legacy code packages at
machine language level (usually with little/no memory remaining)
� Create millions of source code lines in an era of little accepted SW process standards or tools
� Sea-06V/IBM ran intensive BSY-1 CCBs � All problems and change requests graded for
severity, assigned priority � Software CCB dealing with 8-15,000 PTRs
(Program Trouble Reports) during development
23 Oct 2003 - ESD.36J SPM 22
+
- Software Test in the Shipyard
� Ultimate integration responsibility was shipyard project team responsibility � SUPSHIP chair, Shipbuilder Test department conduct tests and
generate TPRs, NAVSEA/lab representatives, SUPSHIP, ship’s crew (later stages) grade & assign action
� Added shipyard input to Sea-06V/IBM (prime) CCB � Flowed shipyard test PTRs up to prime CCB as required- jointly
generated priority
� Dramatically illustrated the difference between ‘Requirement’ and ‘Nice to Have’ � Started yard test with 8000+ TPRs � Went to initial sea trials with just under 4000 open TPRs
23 Oct 2003 - ESD.36J SPM 23

- Critical Importance of Broadband
The critical safety sensor for submerged operations
23 Oct 2003 - ESD.36J SPM 25
+
- The BSY-1 Broadband Problem
� The level of integration, additional acoustic processing, and software structure provided excellent performance, but � System crashes were still occurring 3 months
before scheduled sea trials � Following such a crash, a system re-initialization
(all functions of equal priority) required more than 5 minutes
� 5 minutes ‘blind’ in sea trial submerged operations off Long Island (or elsewhere) was unacceptable!
23 Oct 2003 - ESD.36J SPM 26
+
- Risk Mitigation Project
� All SSNs carried HP85 portable computers for calculating SONAR conditions from temperature and salinity (among other) data to predict performance
� SSNs have a ‘line array’ (BQR-7) with far fewer acoustic elements than the sphere, but proper orientation/frequency characteristics for a simple, less capable forward- and side-looking SONAR
� Cabling from BQR-7 ran near SONAR room and HP85, but had no connection point and no suitable beamforming capability
23 Oct 2003 - ESD.36J SPM 27
+
- A ‘Baby Broadband’ is Born
The HP85 and BQR-7 were combined in a ‘rapid prototype’ generation of a back up broadband SONAR � Programming done by NUSC engineers � Cabling changes designed by NUSC,
completed by shipyard � Resulting unit worked so well it was
replicated for several additional ships � SSN 751 never lost broadband on sea
trials 23 Oct 2003 - ESD.36J SPM 28
+
- Bow Planes and Grease
� Bow planes on WWII submarines folded, but were not retractable
� Dynamics of high speed ship control and flow noise targets required retractable planes for 688i
� Retractable planes require lubrication
23 Oct 2003 - ESD.36J SPM 30
+
- Dynamic & Acoustic Considerations
23 Oct 2003 - ESD.36J SPM
688- Planes near center of pressure, in flow field of sail
688i- Planes forward on large moment arm, in main hull flow field
31
+
- Bow Planes, Grease & SUBSAFE
� Following loss of the Thresher, the Navy instituted a new program called SUBSAFE � History and substance of SUBSAFE
� Only hull penetrations exempt from SUBSAFE were those with <0.25” diameter
� Proposed grease line was D=0.75” except where it passed through elliptical bulkhead, where it necked to D=0.25”
� Grease flow characteristics � Pump designed for 3500 psi; tested to 10000- no
grease flow!
23 Oct 2003 - ESD.36J SPM 32
+
- Magic ‘Blue Grease’
� UK allies identified a synthetic lubricant with much better flow characteristics
� Suggested ‘blue grease’ worked at acceptable pressures
� Seals designed to leak…and did � Can you track a 688i using blue grease
detection technology? � By the way, the answer is ‘No’!
23 Oct 2003 - ESD.36J SPM 33
+
- Lasers vs. Experience
� Critical alignment point in torpedo room is the ‘Load Line’
� Must maintain alignment to acceptable tolerances at all depths (to quote Jane’s Fighting Ships, “greater than 400 feet…”)
� All structure in the room compresses and expands with depth excursions
� Solution: Use state-of-the-art laser theodolite alignment methods, coupled with extensive FEM models
23 Oct 2003 - ESD.36J SPM 35
+
- Experience Wins!
� Following weeks of extensive measurements and intensive (and expensive) adjustments, initial load line measurements on trials yielded unacceptable results
� Prior to noise and weapons trials, the two waterfront gurus (no degrees, but 80+ years combined experience) ‘eyeballed’ the room and provided required adjustments
� On successive trials, load line was measured and confirmed within specification
23 Oct 2003 - ESD.36J SPM 36
+
- Summary- Key Success Factors
� Methods and tools are an important part of preparation, but can only supplement: � Thorough technical understanding of major
project content � Intense and repeated reviews of project
assumptions, risk and risk mitigation requirements
� Comprehensive leadership, personal commitment, professional judgment and understanding of the human capital available in project teams
