Hi Tony,
Would that it were so simple!
The knowledge types I am refering to are the types of knowledge people posses:
|
Explicit
|
Information that can be got through conversation, interview and questioning.
Example: Are only UK addresses in scope?
|
|
Tacit
|
Sort of knowledge that a doctor uses to diagnose patients. This knowledge is built up from years of training and experience and cannot easily be conveyed verbally.
Example: try explaining verbally how to maintain your balance on a bicycle.
|
|
Semi-Tacit
|
What everyone assumes everyone else knows. Major source of errors for Business Analysts as the users will assume that the Business Analyst knows this information and (worse) the Business Analyst might assume they know it as well but they don’t!
Example: Obviously, everyone knows that cars stop at red traffic lights. This example shows the dangers of semi-tacit knowledge: in America on a right turn, if the road is clear cars do NOT stop at red traffic lights which is pretty important to know if you are pedestrian!
|
Then (so they say) there is this fourth knowledge type: Future System. The only definition I have is
"This is what users and other stakeholders think they know about the new system – they are their predictions for what will be true after the new system has been implemented.
Example: When the new system is in place postcodes will be verified automatically.".
However, this is disputed and I wondered if there is an accepted defintion in the BA community (there does not seem to be one on the internet).
Even by Business Analysis standards, this a vague term!!!
