An Objective Perspective on
Knowledge Management
The Typical Starting Point:
Explicit vs. Tacit Knowledge
? Explicit Knowledge:
? Can be expressed in words and numbers
? Easily communicated and shared in hard form
? Examples: scientific formulas, market data, codified
procedures
? Tacit Knowledge:
? Difficult to formalize
? Examples: scientific expertise, operational know-how, industry
insights
Three Essential Components of
Knowledge Management
? Knowledge discovery and capture
? Knowledge organization
? Knowledge sharing
Implementing Knowledge Management
? Business Intelligence
– Processes used to enable improved decision
making
– Data mining and warehousing, advanced
technologies that glean valuable insight from
stored data
? Knowledge Discovery
– Text mining techniques enable knowledge
discovery from text sources
? Knowledge Mapping
– Knowledge sources (people & information) are
represented in a context defined by relationships
? Expertise Location
– Finding, cataloging & making available the best
expertise in the corporation when needed for
business decision making
Implementing Knowledge
Management (cont.)
? Collaboration
– Enables people to share information, expertise
& insights
– Amplification of tacit knowledge
– Enhanced innovation & motivation
? Knowledge Transfer
– Extends reach of available knowledge & skill
transfer resources to remote locations
– Enables virtual teams to perform at high-level
organization standards, independently of the
geographical location of the team members

A Common Definition of Knowledge
? No clear consensus despite long history of epistemology
? Knowledge comprises individual beliefs that:
– Define cause and effect relationships
– Enable value judgements
– May also include learned or acquired skills
Increasing ability
to define value or
relevance in
context
Wisdom
Knowledge
Information
Based on common syntactical
rules—explicit and accessible
to many
Based on deep understanding
of underlying relationships—
individually idiosyncratic and
accessible to few
A key challenge is characterizing knowledge outside the realm of practice
Knowledge is Embedded in All
Aspects of Organizational Activities
? Product Technology
? Process Technology
? Organizational structure and reporting
relationships
? Group norms and values
? Informal information flows
Knowledge is a By-product of Individual
and Organizational Activity
Enterprise Knowledge Evolves
Over Time
? Knowledge in use evolves with changing activities
and priorities
? Cyclical process that builds upon past experience,
capabilities, and relationships
– Enterprise may draw on internal or external
sources as needed to satisfy requirements
? Experience, capabilities, and relationships are
adapted as new requirements emerge
– Dramatic changes (increased novelty) force
equally significant changes in knowledge in use
and relationships that link that knowledge
together

Knowledge Management in Complex
Settings Forces Focus on Boundary-
spanning and Integration
? Demands of system performance require multiple actors with
specialized knowledge working in concert
– Boundaries differentiate the actors but also potentially
inhibit communication and collaboration
? Specialization of tasks means that no single actor has all the
answers — forcing integration of activities and creating mutual
dependence
? Over multiple cycles, relationships between specialized
sources of knowledge are developed to improve process
performance
– System architectures
– Learning curves
? Novelty from cycle to cycle potentially disrupts BOTH
competence within areas of specialized knowledge and
relationships between or across boundaries

Characteristics of Boundary Objects and
Boundary Infrastructures
1. Establishes some shared language/syntax of
representing each other’s knowledge.
2. Provides individuals a concrete means of
specifying their differences and dependencies.
3. Allows individuals to negotiate and transform
their knowledge to collectively create new
knowledge.
4. Supports an iterative approach where individuals
get better at representing, specifying and
transforming knowledge.

Emerging Findings Around
Adaptability in the Design Phase
? Effective System Representations (SR) enable adaptability by
facilitating knowledge transfer between stakeholders
– SR’s portray the evolving design and facilitate “what if”
analyses
– Stakeholders used SR’s to identify and evaluate adaptations
? SR effectiveness depends on fidelity, timing and usage
– Fidelity: show system level detail & high interest aspects of
design
– Timing: provide insight while trade space is still open
– Usage: in-depth SR interaction by knowledgeable
stakeholders
? The user makes a valuable contribution to design by sharing
operational considerations – often underutilized!
– Timely feedback promotes improvements by helping
designers understand how operators foresee using the
system
– Prioritizing needs allows bounding of overall scope to
manage risk

Political
Characteristics
Cultural
Characteristics
Political characteristics
provide “traction” for the
strategic direction within
the organization
Cultural characteristics inform and guide the
behaviors that fulfill the strategic direction
Strategic characteristics provide the foundation and
operating context for successful PLE efforts
Strategic Characteristics
? Goals and metrics:
– Strategic plans clearly defined goals relating to
the development of platforms and/or product lines
– Metrics used that apply specifically to product line
engineering
? Amount of technology sharing
? Extent to which a product meets established coherence
requirements
? Number of derivative products a platform can generate
? Amount of unique part numbers
– Organization-wide coherence requirements
reinforce platform and product line strategy
Strategic Characteristics, cont.
? Strategies:
– Product line engineering strategies implemented uniformly
across organization (e.g., “zero tolerance policy”)
– Smallest percentage of projects use new design strategy
– Over half of projects leveraged product development through
concurrent technology transfer (a defined strategy for
knowledge transfer from one project to another overlapping
project)
? Resource and technology sharing:
– Resources organized around platforms to dictate resource and
technology sharing
– Individuals designated to recognize and act upon
opportunities for organizational sharing
– Modular system architectures to facilitate sharing
– Initiatives to standardize components and parts to increase
technology sharing
Political Characteristics
? Management and Stakeholders:
– Senior management defines and enforces product
line strategies (not a “grass roots” movement)
– Supplier stakeholders have “buy-in” to platform
strategy through risk-sharing partnerships
– P&L responsibility at a level where decisions can be
made at the portfolio level
? Responsibility and accountability:
– Responsibility for maintaining platform and
derivative alignment held at a high level in the
organization
– Change control boards comprising platform team
members control platform architectures
Cultural Characteristics
? Communication and training:
– Communication modes defined specifically to
convey product line engineering strategies
– Communication modes designed to facilitate
resource and technology sharing
– New employee orientation covers general
product standards and specific product lines of
the organization
Product Family Management Process
Observations
? Senior management buy-in to phase gate process
? Continuous review of how projects line up against
strategy
? Ensure new products fit within strategic plan
? Formal product development process defined
? Formal portfolio management processes in place
Observations consistent with previous LAI research
on managing the front end of product development
Taking a Lifecycle View Requires Perspective
Across Multiple Enterprises and Stakeholders
Source: Murman et al., Lean Enterprise Value, Palgrave, 2002
Examples of Commonality in
Lifecycle Operations
? Commercial Airline:
– Main engine starter is common across 747-400, 767,
and 767-300ER
– 26 airports service these aircraft (11 common)
– Airline only has to stock 14 spares, as opposed to 25 if
they were not common
? PMA-276
– UH-1Y and AH-1Z deploy together on the same MEU,
relying on the same mobility, maintenance, training,
and sustainment infrastructure
– 85% commonality between UH-1Y (utility) and AH-1Z
(attack) reduces the detachment maintenance
personnel requirement from between 4 and 14 people
(3 to 12%)
– Nearly $1.5 billion in savings from commonality over 20
year lifecycle of program

Research Finds Limited Evidence That
Knowledge Sharing Infrastructure Exists in
“Downstream” Product Lifecycle
? 5 Fleets of aircraft with ~decades legacy between
EOM and user communities
? Operating data painstakingly collected by
maintainers
– Paper-bound but willingly shared
? OEM has little/no insight into data sources or
lessons to be learned
? Operating metrics and data proved useful in a
sample of subsystems to guide a redesign of the
product architecture
? Spurs new models for customer/OEM
relationships and enterprise interfaces
Intellectual Capital Defined
? IC is intellectual material -- knowledge,
information, intellectual property (IP), and
experience -- that can be put to use to create
wealth and value
? Includes:
? employees’ skills
? patents & trade secrets
? an organization’s technologies, processes, and
experience
? info about customers and suppliers
Assertion: IC, like other forms of capital, can be
made more productive through proper management
From presentation by Rebentisch at LAI Plenary conference, March 2002
Investigating “Design Team Capability”
? Recent LAI study on role of IC in aircraft design:
? Setting: new commercial aircraft designs over a
generation of change in the industry
– Same target markets
– Company-funded development
– Same FARs, certification requirements
– Mature multi-product firms (with significant
military business)
? Data based on interviews and extensive archival
document search

Comparing 4 Commercial Aircraft
Programs in a Study
? Ranked performance across all 4 programs:
– Design effectiveness (i.e., weight, range, etc.)
– Design quality (i.e., ECPs, etc.)
– Program performance (i.e., milestones)
– Intellectual capital (e.g., # new designs in prior
10, 20 years, management depth, skills)
? Sum scores and check for correlation
Depth of IC is positively correlated with
design and program performance
From presentation by Rebentisch at LAI Plenary conference, March 2002
Study Observations
? Strong Linkage between IC metrics and Program Performance Metrics
? 70s-era design efforts outperformed the 90s-era efforts in
meeting program/ performance objectives
– Better weight, payload margins; closer to delivery
milestones
? Performance extremes were in the same company—allowing
convenient comparison
– Can address evolution of in-depth through
interviews with “graybeards” and documents
? Test phase an important downstream indicator of design
performance and IC
– Test personnel positioned to understand design
system weaknesses through exposure to recurring
problems

Footnote to A70 Design Experience
? Evolutionary derivative program 7 years later experienced
greater difficulties
– Delayed type certification
– Reduced performance (poor weight control)
? WPP tool still existed, but originating team had moved on
to new assignments
– Discipline to use WPP methodology was not as
strong as in original A70 program
– Other codified lessons learned were circumvented
Perceived relevance of captured knowledge (WPP
and others) was apparently affected by passage of
time and turnover in workforce

From presentation by Rebentisch at LAI Plenary conference, March 2002
Contrasting the A70 and A90
Design Experiences
? A70:
– Management team built on senior engineering leadership
emerging from a key military program competition victory
– Hand-picked team of senior engineers with experience on
multiple programs—”fully staffed” program
– Aggressive use of lessons-learned and risk reduction
strategies (employing familiar, common tools and concepts)
? A90:
– 1 prior major program from which to draw experiences (but
housed in a separate facility
– Program leadership experience primarily with
legacy/derivative program; few key players (1-deep at times)
from flight sciences
– Manufacturing quality higher as a result of advanced design
tools
– Simulation tools graphically compelling, but underlying data
deficiencies (in part due to reduced reliance on wind tunnel
testing) lead to late design changes
From presentation by Rebentisch at LAI Plenary conference, March 2002
Summary Observations From Intellectual
Capital Research
? Knowledge capture and/or knowledge codification methods may be only
partially effective if not backed up with experience in practice
? Prototype and experimental aircraft experience alone is inadequate to bring
a new aircraft design through certification and rate production
? There must be adequate "critical mass" of intellectual capital—a few stars
can’t carry the entire team
? Use of modern design tools:
– Modern computational tools did not fully offset impact of
intellectual capital declines on program performance
– Failure to refresh/support knowledge systems resulted in mis-
prediction/rework that caused major delays
– Modern computational tools can inhibit development of user
tacit knowledge compared with predecessor analysis methods.

Implications: Thinking About Investment in
IC/KM Tools
NPVIC= discounted value of future net IC contributions to
enterprise performance
Investment in people and tools may increase net IC productivity
and yield a return to the enterprise, but:
– Organizational return from knowledge creation
decays with time
? Employee turnover, new requirements,
forgetfulness, etc.
– Current productivity metrics make economic
justification of IC/KM investment difficult

Illustration from DoD 4245.7-M, 1985
? “Production breaks” make the next unit more expensive because
of “lost learning”
? IC analogy: years between exercise of design skills results in
higher costs due to relearning or mistakes not avoided
– Case studies showed that programs with broken or
disrupted IC continuity with prior programs suffered in
performance and programmatics
From presentation by Rebentisch at LAI Plenary conference, March 2002
Strategic Choices Around Knowledge Creation
Illustrative knowledge creation and capture investment strategies:
? Short-term (periodic and predictable customer pull for new
products):
– Firm bridges gaps in knowledge creation activities
through own investments in development of derivatives,
IRAD, productivity enhancements
? Long-term (many years until next new design):
– Externalize cost of knowledge creation by allowing
customer to fund technology demonstrations, concept
studies, and prototypes
– Customer or firm adopts “spiral” or adaptive
development process to “load level” design experience
over several years
– BUT–customer acknowledges and accepts potentially
significant relearning penalties to develop follow-on new
products if the break in knowledge creation activity
stretches on too long
