we can start drawing current reality tree
CRT depicts as it is and focuses on undesirable effects in our processes.
-
It seek cause and effect connection and connects them with whole system’s condition and tries to find genuine causes.
-
CRT is designed to reach next objectives:
- Understanding of complexity and the system.
- Articulate what inhibits development of the system. UDE. Effects that are contradicting goals, CSF and NC.
- Work from top UDE to the root cause and see where the problem is lying.
- Identify which root cause creates the worst effect on the system.
- Determine which of the RCs a lying beyond our spheres (control and influence).
- Isolate few causal factors (constraints)for maximum effectiveness of the system? (how is it done?).
- Search for simplest potential changes. TRIZ law of ideal object. [[Идеальный объект]]
-
Working with CRT we assume that:
- cause and effect is not correlation.
- Correlation embedded in CRT are invalid. They isolate wrong causes and lead to incorrect root causes. Cost energy and effort. BEWARE.
- Decisions based on them less sound than those that are based on cause and effect.
- CLR can help us not to fall victim to correlation.
- all elements of the system are interdependent.
- all processes could be changed.
- both effects are produced DE and UDe.
- Several UDE are working in accord.
- cause and effect are managed by CLR and subjected to scrutiny beforehand.
- there are unstated assumptions.
- all cause and effects are replicable in every next iteration. If not then changes have been made.
- cause and effect is not correlation.
Good example of synthetic problem. Marshak have translated the poem inside, Could be adapted into Russian.
[[an example on which CRT building could be practiced]]
The main objective of CRT it to isolate what needs to be changed.
- CRT if properly depicted overlaps spheres of control, influence and outside uncontrolled environment
Undesirable effects p.101
By what standard?
To determine UDE phrase the effect in grammatically sound full sentence it can identify UDE as UDe or fact of life that can’t be influenced.
- Next step is to check for negativity:
- Do others agree with me on that? That UDE is negative in correlation to goals CSF and NC? Numbers don’t mean anything.
- Agreement of society. Would they see negativity as I see it. For example, bad marks of a student is a problem of bad education, unskillful teachers or lack of attention to what children do at home?
- Does UDE constitutes an unacceptable deviation from the goal?
- Does it affect throughput of the system?
If we have several root causes, a good habit is to determine which RC is guilty for 70 percent of UDE or simply put for the majority of problems. And deal with it. When we were reading [[Thought and Knowledge An Introduction to Critical Thinking]], Halpern introduced rule of making good decision it is called 2/3 rule. It can be measured by a specifically designed worksheet.
Core problems are not root causes. CP builder is trying to tie up several disparate branched, which in beg trees leads to expenditure of resourced and brings cognitive stress, when working with RC is much easier, though it also has some drawbacks.
Firstly, dealing with RC requires consensus of what ISN’T UDE, IOM helps in that. It helps us understand what’s good for the system and what should be happening, and limits our ability on putting tags on everything that might be undesirable. Secondly, in building our tree we stop looking for vague and over-broad core problems and concentrate on a few RC. But the IOM needs to be drawn in the first place.
Don’t plant any CRT without drawing IOM!
Definition of critical root cause:
A critical root cause is a policy, practice, or prevalent behavior that constitutes the lowest level of causality in existing reality lying within someone’s sphere of influence to change.
Solving problems starts with a search of a conflict. And if search is thorough, we can find several conflicting problems. Reach one goal and second goal destabilizes. To resolve the conflict Dettemer offers a tool for conflict resolution Evaporating cloud
