KM-05: Capturing Tacit Knowledge
What Is Knowledge Capture ?
A process by which the expert’s thoughts and experiences are captured
A knowledge developer collaborates with an expert to convert expertise into a coded program
In simple terms, we want to “know” how experts know what they know 4-3
KM-05: Capturing Tacit Knowledge
Three important steps
Use an appropriate tool or technique to elicit information from the expert
Interpret the information and infer the expert’s knowledge and reasoning process
Use the interpretation to build rules that represent expert’s solutions 4-4
KM-05: Capturing Tacit Knowledge
Improving the Knowledge Capture Process
Focus on how experts approach a problem Look beyond the facts or the heuristics Re-evaluate how well the problem domain is understood How accurate the problem is modeled 4-5
KM-05: Capturing Tacit Knowledge
Using a Single Expert Advantages: Ideal when building a simple KM system A problem in a restricted domain Easier to coordinate meetings Conflicts are easier to resolve Shares more confidentiality than does multiple experts 4-6
KM-05: Capturing Tacit Knowledge
Using a Single Expert (cont’d) Disadvantages:
Sometimes expert’s knowledge is not easy to capture
Single expert provides only a single line of reasoning
Expert knowledge is sometimes dispersed
Single expert more likely to change scheduled meetings than experts in a team 4-7
KM-05: Capturing Tacit Knowledge
Using Multiple Experts Advantages:
Complex problem domains benefit from expertise of more than one expert
Working with multiple experts stimulates interaction
Allow alternative ways of representing knowledge
Formal meetings often a better environment for generating thoughtful contributions
4-8
KM-05: Capturing Tacit Knowledge
Using Multiple Experts (cont’d) Disadvantages:
Scheduling difficulties
Disagreements often occur among experts
Confidentiality issues
Requires more than one knowledge developer
Overlapping mental processes can lead to “process loss” 4-9
KM-05: Capturing Tacit Knowledge
Developing a Relationship With Experts
Create the right impression Understanding the expert’s style Prepare well for the session Decide where to hold the session 4-10
KM-05: Capturing Tacit Knowledge
Approaching Multiple Experts Individual An
extension of single expert approach
Primary
and secondary
Start
with the senior expert first, on down to others in the hierarchy
Small
groups
Each expert tested against expertise of others in the group 4-11
KM-05: Capturing Tacit Knowledge
Analogies and Uncertainties in Information Experts
use analogies to explain events
Expert’s
knowledge is the ability to take uncertain information and use a plausible line of reasoning to clarify the fuzzy details 4-12
KM-05: Capturing Tacit Knowledge
Analogies and Uncertainties in Information (cont’d) Reliable
knowledge capture requires understanding and interpreting expert’s verbal description of information, heuristics, etc.
For
example, words like possible, likely, and definite show relationships between words and belief 4-13
KM-05: Capturing Tacit Knowledge
The Interview As a Tool Commonly
used in the early stages of tacit knowledge capture
The
voluntary nature of the interview is important
4-14
KM-05: Capturing Tacit Knowledge
The Interview As a Tool (cont’d) Interviewing
as a tool requires training and preparation
Convenient
tool for evaluating the validity of information acquired
4-15
KM-05: Capturing Tacit Knowledge
Types of Interviews
Structured: Questions and responses are definitive. Used when specific information is sought
Semi-structured: Predefined questions are asked but allow expert some freedom in expressing the answers
Unstructured: Neither the questions nor their responses specified in advance. Used when exploring an issue
4-16
KM-05: Capturing Tacit Knowledge
Variations of Structured Questions
Multiple-choice questions offer specific choices, faster tabulation, and less bias by the way answers are ordered
Dichotomous (yes/no) questions are a special type of multiple-choice question
Ranking scale questions ask expert to arrange items in a list in order of their important or preference 4-17
KM-05: Capturing Tacit Knowledge
Guide to a Successful Interview
Set the stage and establish rapport Properly phrase the questions Question construction is important Listen closely and avoid arguments Evaluate session outcomes 4-18
KM-05: Capturing Tacit Knowledge
Things to Avoid Taping
a session without advance permission from the expert Converting the interview into an interrogation Interrupting the expert Asking questions that put the domain expert on the defensive 4-19
KM-05: Capturing Tacit Knowledge
Things to Avoid (Cont’d) Losing
control of the session Pretending to understand an explanation when you actually don’t Promising something that cannot be delivered Bring items not on the agenda 4-20
KM-05: Capturing Tacit Knowledge
Sources of Error that Reduce Information Reliability Expert’s
perceptual slant Expert’s failure to remember just what happened Expert’s fear of the unknown Communication problems 4-21

Problems Encountered During the Interview Response

Nonaka’s Model of Knowledge Creation and Transformation TACIT TO TACIT (SOCIALIZATION)
TACIT TO EXPLICIT (EXTERNALIZATION)
e.g., Individual and/or Team Discussions
e.g., Documenting a Team Meeting
EXPLICIT TO TACIT (INTERNALIZATION)
EXPLICIT TO EXPLICIT (COMBINATION)
e.g., Learn from a report and Deduce new ideas
e.g., Create a Website from some form of explicit knowledge; Email a Report 4-24

Build vs. Buying Option Cost In-house Usually high development
Time Factor Much shorter than development by user
Customization High, depending on quality of staff
Development Usually low by end users
Depends on skills High to the user set, system priority, specifications and so forth
Outsourcing Medium to high Shorter than in-house
High
Off-the-shelf Low to medium Nil Solution
Usually up to 80% usable 3-27

Deciding where to hold the sessions Beneficial
in recording the expert’s knowledge in the environment where he or she works
An
important guideline is to make sure the meeting place is quiet and free from interruptions
