Knowledge Management
Baskar Subbarao Sarah Sullivan Michael Tobin
Knowledge management reflects a point made by Lew
Platt, former CEO of Hewlett-Packard "If HP
knew what HP knows, we would be three times as
profitable."
Ref. 28

Introduction - KM
  • Before something can be managed, it must be
    understood.
  • A discussion of Knowledge Management must start
    with
  • Data Data Management
  • Information Information Management
  • Knowledge Knowledge Management

3
Background of Knowledge Management
  • Although knowledge and management have been
    around for a long period of time, the topic of
    Knowledge Management is fairly new and is
    generating much interest and study.
  • Neither information management, nor information
    and communication technology are the same as
    Knowledge Management.
  • Information management is data based and
    generally addresses information which can be
    processed by the programming of computers.
    Information management has influenced knowledge
    management and indeed plays a role in the
    knowledge management process.
  • Information and communication technology (ICT)
    often act as a catalyst for Knowledge Management.
    The availability and development ICT has
    facilitated the Knowledge Management process.

Background of Knowledge Management
  • DATA
  • Data includes Facts, figures, statistics
  • Data is easy to store, sort, and manipulate (it
    is greatly enhanced by ICT)
  • Data is clear cut and concise
  • Data is of limited value by itself
  • Data is very easy to share
  • EXAMPLES OF DATA

6
Data and Data Management
Information
Data
Knowledge
DATA is a collection of discrete, factual
records Data Management The storage and
addressability of data. Purpose - Ensure that
data resources are continuously available for
manipulation and interpretation.
7
Background of Knowledge Management
  • INFORMATION
  • Information consists of patterns of data
  • Information is developed when people analyze
    Data and put into useable terms
  • How the Data is interpreted can change from one
    person to another
  • The value of Information is increased over raw
    Data, but so is ambiguity
  • Information is relatively easy to share, open
    to various interpretations
  • EXAMPLES OF INFORMATION

Ref. 11

Information Management
Information
Data
Knowledge
  • Information is meaningful organization of data
    that is communicated.
  • It is a complex function with
  • Specific intentions of the originator
  • Specific context
  • Depends on interpretation by recipient.
  • Specific goal
  • Information Management
  • Management of the communication channels that run
    between the people in an enterprise.

9
Background of Knowledge Management
  • KNOWLEDGE
  • Knowledge is the information inside peoples
    minds
  • Knowledge is the understanding of the
    information data
  • Knowledge is very valuable
  • Sharing of knowledge is much more difficult
    than the sharing of data or information
  • The creation of knowledge in organizations is a
    collective process of sense making.
  • EXAMPLES OF KNOWLEDGE

Ref. 7

Knowledge
Information
Data
Knowledge
  • Knowledge is the meaningful organization of
    information.
  • Knowledge includes Data, Information and personal
    experience know how
  • Knowledge consists of Explicit knowledge and
    Tacit knowledge
  • Results in a greater use and sharing of valuable
    information and thus eliminates the need for
    everyone to reinvent the wheel

11
Background of Knowledge Management
  • KNOWLEDGE
  • Knowledge in peoples heads is the most
    important resource a company has. Only a small
    amount of a companys knowledge is available in
    exchangeable data files.
  • It is the explicit and tacit knowledge which
    makes up the knowledgebase of a company.
  • Explicit Knowledge
  • Explicit knowledge is easy to code, it comes in
    the form of books, company policy manuals,
    mission statements, company documents, databases,
    reports and etc.
  • Tacit Knowledge
  • Tacit Knowledge is hard to code and extract. It
    is the practical knowledge on how to get things
    done and personal knowledge based on individual
    experience. Tacit knowledge is invisible and the
    most difficult to share.
  • EXAMPLES OF TACIT KNOWLEDGE

Ref. 30
12
Managing Knowledge
  • Managing Knowledge well means creating an
    culture that demands, supports, encourages and
    rewards the sharing of knowledge. This includes
    paying attention to people and organizational
    structure, as well as to the information
    technology for knowledge sharing and use.

13
KM Interview - Accenture
  • Knowledge is important for the success of the
    company.
  • Knowledge Source - People on the front lines,
    actually doing the work.
  • Knowledge Users - Everyone.
  • Knowledge captured in databases usually
    self-submitted, sometimes external.
  • Distribution Next generation mobile devices.
  • KM tools used - Intranet and proprietary
    software.
  • People aren't threatened by KM.
  • Success Criteria Difficult to measure value.
    Showing value is difficult. Support from company
    leadership is critical.
  • KM obstacles - Lack of management support, Poor
    communication and communication devices,
    financial resources
  • Lisa Pappalardo, has a Masters in
    Industrial/Organizational psychology and has been
    with Accenture for over six and half years.

14
Have you ever heard of a little company called
General Electric?
  • Annual Sales Roughly 132 billion
  • Major Products Power systems, aircraft engines,
    plastics, television media, medical systems,
    consumer finance, corporate finance, lighting,
    real estate, insurance, transportation,
    appliances, to name a few
  • Who are GEs customers? Just about everyone!
  • Who is the CIO? Gary Reiner, a GE veteran
  • Who does he report to? The CEO

Ref. 17,22
15
A case study General Electrics Knowledge
Management success 
  • Jack Welch took over in 1981
  • GE must become
  • Lean, and
  • Agile  

16
Why was the change needed?
  • A decision that should have taken a half an hour
    would take months
  • GEs numerous reporting layers hindered the flow
    of information
  • From the top down, and
  • The bottom up   

17
I mean business
  • Become either 1 or 2 in its respective area, or
    face the consequence of being divested   
  • Welch cut nearly 20 of the global GE workforce
  • So in his first moves, he let them know he meant
    business

18
The culture shifts
  • It was at this point that Welch believed the
    company was primed for the vision.  
  • Welch began his crusade with changing the culture
    at GE
  • Shun the incremental and go for the leap
  • He started with attitudes
  • He started at the top  

Ref. 5
19
TALK TO ME!!
  • Welch began
  • The constant interactive process
  • Aiming to produce consensus
  • Teaching by example that listening was more
    important than talking
  • Emphasizing that Real communication takes
    countless hours of eyeball to eyeball contact
  • Idealizing honesty and clarity as business
    imperatives  Those managers who could not get
    on board with GEs new vision, well, they had to
    go  

Ref. 5
20
Share the vision
  • The next steps
  • Ensure that every single employee understood what
    the business was trying to achieve
  • Engender self-confidence in his people, which he
    believed to be central in unfettered
    organizational communication  people who were
    freed from the confines of their box on the
    organizational chart, whose status rests on
    real-world achievement-those are the peoplewho
    share every bit of information  

Ref. 5
21
See how easy this is?
  • Business isnt complicated. Complications arise
    when people are cut off from information they
    need  
  • As people began to feel free to exchange
    information, decisions that used to take months
    were taking minutes

Ref. 5
22
Let the games begin!
  • Corporate Executive Council
  • An intensive 2-day session
  • Held quarterly
  • To candidly and openly share ideas and
    information

23
And KM takes shape
  • Welch soon began 2 extremely significant KM
    programs  
  • Work Out
  • Best Management Practices  

24
Work Out
  • The Work Out Process 
  • Based upon the sharing of knowledge internally
  • Brings thousands of employees together to share
    knowledge and perspectives
  • Fights middle managements tendency to do
    nothing with ideas from below
  • -hot seat example
  • Encourages trust, teamwork, independence and
    confidence in the system
  • Allows for empowerment of the employees, thereby
    doing more with less  The goal of Work-Out was
    to get to a point where people challenge their
    bosses every day 

Ref. 5,16
25
Best Management Practices
  • Best Management Practices 
  • Based on the gathering of external knowledge
  • Involves a system whereby
  • weaknesses are identified
  • superior processes are located
  • -Welch goes to market example
  • those processes are communicated
  • those practices become embedded in the company
    through intensive and extensive training  

Ref. 16
26
If you build it, will they come?
  •  
  • GE employees are continually motivated to
    participate in KM programs by 
  • Compensation plan overhaul
  • Stock and bonus awards
  • Strong cultural promotion of KM  
  • Intense management support of KM
  • Evaluation criterion for success within GE
  • Re-defined the internal concept of loyalty from
    giving time to an affinity among people who
    want to grapple with the outside world and win

Ref. 5
27
What has this meant to GE?
  • Ideas developed and implemented as a result of
    the Work-Out process saved over 200,000 in
    1991 
  • GE expects a 5 to 1 return on every dollar of
    working capital invested 

Ref. 5
28
Can I get a CIO over here?
  • In 1996, Welch appointed GEs first ever CIO,
    Gary Reiner.
  • Reiner encouraged employee use of technology in
    KM by
  • Eliminating other options so the only option left
    is the one we want them to take
  • Get complete company support and commitment, from
    the top down
  • Talk to you internal customers listen to what
    works, and what doesnt

Ref. 26
29
Examples of it all coming together
  • Destroy Your Business!!
  • GE Capital Fleet Services
  • GENet
  • GE Answer Center USA

30
Applying what we have learned for the future
  • As a result of the huge amount of knowledge GE
    has gained, GE took on a new 3-prong e-business
    strategy to improve yet again in the processes
    of
  • Making goods
  • Buying goods
  • Selling goods  

31
The make side
  • Digitize internal processes for competitive
    advantage
  • Aims to eliminate manual and paper processes to
    increase efficiency
  • Get there by using the Six Sigma process
  • -Process starts with mapping workflow and
    determining the cycle of corresponding actions
  • -Desired result is to reduce defect rates,
    improve productivity, and efficiency  
  • Current implementation identified 1.5 billion in
    cost savings for 2001 

Ref. 17
32
The buy side
  • Apply e-business to improve sourcing and
    purchasing
  • E-Auctioning which provided 480 million in
    annualized savings in the first 6 months
  • The process drives costs down by a competitive,
    open bidding process  The price of a each
    transaction has decreased by about 8  

Ref. 17
33
The sell side
  • Digitize the online sales process
  • New customers are attracted through online
    offerings
  • Old customers are migrated to the online system
     Online transactions have grown from 0 to over
    7 billion in 3 years  

Ref. 17
34
Other successes resulting from GEs KM process
  • Mentor program provides for reverse mentoring for
    top management, regular meetings and reviews on
    e-business learning's and practices, discussion
    groups for best practice sharing
  • The Six Sigma approach to quality significantly
    reducing manufacturing errors
  • 2001 won Most Admired Knowledge Enterprises study
    for world-class effort in managing knowledge,
    resulting in superior performance
  • (noted in subcategories Establishing an
    enterprise culture, management support for
    managing knowledge, maximizing the value of
    intellectual capital, establishing a culture of
    continued learning, managing customer knowledge
    to increase loyalty/value, manage knowledge to
    increase shareholder value.)

35
GEs Corporate Values

37
Lessons learned
  • It starts at the top
  • Dont be afraid of change
  • Share ideas, and promote idea sharing
  • Culture is KEY

Explicit Knowledge
Tacit Knowledge
  • Tacit Knowledge often takes the form of a mental
    model
  • Beliefs and perspectives so ingrained that they
    are difficult to articulate.
  • It's the wisdom and expertise in people's heads

Written or otherwise recorded. It can be readily
identified, articulated, captured, shared, and
applied. Examples - Books, manuals,
patents, databases, reports, libraries,
policies, and procedures.

Knowledge Management - Aspects
  • Five aspects to be considered
  • 1. People or personnel (who does the work)
  • 2. Culture, communication, corporate climate,
    society (where, when and why the work gets done)
  • 3. Processes (how the work gets done)
  • 4. Resources (what can help work get done
    better-- intellectually)
  • 5. Tools, including technology (what can help
    work get done better--physically or mechanically)

  • Secure resources
  • Promote best practices and outcomes
  • Champion Education
  • Champion communities of practice
  • Create and Use Common Language
  • Provide Tools Technology
  • Use incentives and Awards
  • Measure outcomes

63
12 Guiding Principles of KM
  • Knowledge is messy
  • Knowledge is self-organizing
  • Knowledge seeks community
  • Knowledge travels via language
  • The more you try to pin Knowledge down, the more
    it slips away
  • Looser is probably better
  • There is no one solution
  • Knowledge doesnt grow forever
  • No one is in charge
  • You cant impose rules and systems
  • There is no silver bullet
  • How you define knowledge determines how you
    manage it

Ref.
64
Challenges to Knowledge Management
  • It is almost impossible to directly tie results,
    sales, income to Knowledge Management
  • As such, the task of judging success or failure
    is not cut and dry. While the importance of
    Knowledge Management may be agreed upon, the
    disconnect between KM and results may pose
    justification challenges. This reinforces the
    need for strong support from the top down.

65
Take Away Points
  • We have discussed how knowledge is in the minds
    of the employees. The extraction of this
    knowledge is a critical portion of knowledge
    management. This extraction presents a
    significant challenge both in process and
    cooperation. In many cases an employees value may
    be tied closely to their knowledge, convincing
    them to share this knowledge and possibly lessen
    their value is a tough task.

66
Take Away Points
  • Mastering Knowledge is a decisive factor for
    success. Optimizing knowledge acquisition and
    knowledge transfer results in competitive
    advantage.

Ref. 7
67
Take Away Points
  • Sharing Knowledge means the wheel does not have
    to be reinvented by everyone.

68
Summary
  • Everyday that a better idea goes unused is a
    lost opportunity. We have to share more, and we
    have to share faster. I tell employees that
    sharing and using best practices is the single
    most important thing they can do.
  • Ken Derr, CEO of Chevron
